These Words Should Send a Chill Down The Building Industries Back!

Maybe you didn't feel it, but on November 12th, the building industry was shaken up. Hard, like they got punched, and punched and punched. The law firm of Walkup, Melodia, Kelly & Schoenberger is representing Aoife Beary and another party who are suing for damages from the result of the balcony collapsing on June 16th of this year.  

The suit asks for damages, enough to make an example out of the defendants, enough so THIS NEVER HAPPENS AGAIN! Every person involved in building decks, especially cantilevered, are now on notice that it better be done perfectly and correctly. OR YOU WILL PAY. Remember to, the DA's office is investigating this too and criminal charges may still come!

BE AFRAID, BE VERY AFRAID! 

NO OSB SHOULD BE EVER USED! THIS LIST OF ALLEGATIONS IS A LIST
OF EVERY DECK PROBLEM I SEE ALL THE TIME

So here you are building industry, property management industry, design industry etc; start designing, building, sequencing and use the right materials cause the deaths of these poor kids WILL NOT BE IN VAIN! READ THIS LIST, IT'S JUST A WHO'S WHO OF THE SINS I SEE DURING INSPECTIONS AND WHEN I WAS WATERPROOFING DECKS! 

LESSON-IF YOU SCREW UP AND PEOPLE DIE, YOU PROBABLY WILL GO TO JAIL AND PAYA WHOLE LOT OF MONEY, AND HAVE TO LIVE WITH THOSE THAT DIED ON YOUR CONSCIENCE. 

NOT WORTH IT, DO IT RIGHT, IT ONLY COSTS A LITTLE MORE THAN DOING IT WRONG. 

From Contra Costa Times- Lawsuits Filed By Victims and Families of Berkeley Deck Collapse

Prior complaints by tenants about mushrooms growing out of balcony allegedly ignored.

Reporter Thomas Peele's (@Thomas_Peele) latest article on the Berkeley deck tragedy reports that the families and victims of the deck collapse have filed a lawsuit alleging some of the defendants named in the suit knew of problems with the deck after it was built and the building occupied. Other defendants allegedly "deliberately ignored" the plans for the deck.

"BERKELEY -- Tenants of a Berkeley apartment had complained to building managers for weeks that mushrooms were growing on a wooden balcony before it collapsed during a party in July, plummeting six people to their deaths, lawsuits filed Thursday allege.

But their complaints were ignored, survivors and families of the victims claim in a negligence lawsuit that alleges the building owners and construction company could have prevented the tragedy."

Read the whole article here- http://www.contracostatimes.com/breaking-news/ci_29110468/berkeley-tenants-reported-signs-rot-weeks-before-deadly

The allegations, if proved true, would leave many of the named parties at risk of being exposed to millions of dollars in liability costs.

I'll say it once again, decks must be built using best building practices and with the highest degree of skill and materials available, not the most cost effective, cheapest materials and labor. If successful, this lawsuit may just change the way builders hire sub-contractors-today the cheapest wins, the most responsible skilled contractor loses. It's time for a change.

Fire Pit Ignites Wood Deck - 60K in Damages is The Result

DO NOT USE FIRE PITS ON DECKS! DO NOT USE FIRE PITS ON DECKS! 

A family escaped with smoke damage to the interior and about 60k in dagaes to their deck and exterior of the home when embers from a fire pit on the wood deck apparently were blown out onto the deck. The deck ignited and the siding did to. Lucky these people weren't killed...

From Contra Costa Times-As Berkeley begins balcony inspections, records suggest safety problems are common in region

shows two balconies falling off a building in San Francisco.
The sliding doors are not blocked to prevent access, a
dangerous condition.

An investigative report on Berkeley's new deck inspection ordinance by Matthia Gafni, David Early Sr & Thomas Peele shows that other Bay area cities with inspection requirements reveals the difficulty in forcing building owners to repair their buildings. Gafni interviewed me on my opinions and expertise on the subject. 

"A rotting deck railing at a San Francisco house suddenly snaps during a birthday party, and three people fall onto concrete below, suffering serious injuries. Posts tenuously prop up the collapsing balcony of four San Jose apartments that city inspectors may soon order vacated, fearing an imminent collapse.

In Concord, inspectors find balconies at an apartment complex badly rotted and order immediate repairs, citing danger to residents.

These details -- gathered from inspection records reviewed by the Bay Area News Group -- suggest just how common the types of problems are that doomed a Berkeley balcony and killed six young adults last month."

My personal professional opinion is landlords and property management companies have decided to not fix decks until someone dies. Read my opinions in the article here at this link. http://www.contracostatimes.com/ci_28538504/berkeley-begins-balcony-inspections-records-suggest-safety-problems

Signs Your Deck Needs To Be Inspected

We have had a lot of traffic recently to our site from people who are concerned about their decks. We want to assure you that your waterproofed deck probably isn't going to collapse, but many wood decks do collapse on a near everyday basis in the US. How can you check your waterproof solid surface deck to see if it has any warning signs of danger?

Do use our photograph's to check your deck for signs of problems and dangerous conditions. If you find these conditions, you'll want to have a deck inspector review your deck and give you a report with a basic scope of work to use to obtain bids with. Don't let a deck waterproofing contractor write his scope of work, they may be complete and truthful or they may be adding extra work and profits on.

Even if your deck is in no danger of collapse, water getting under the surface of a waterproof deck can cause damage to framing and the plywood substrate.

1.) Therefore, cracks on a deck are a warning sign. Look at your deck carefully in the field of the deck. Many times plywood moving will cause a deck to crack.

Urethane deck with seam tape showing through coating.
We recommend a professional inspection and evaluation. 

Long cracks in the field of the deck
should be inspected and repaired. 

Some decks crack because of moving plywood. This deck's
coating cracked because of plywood not being level. 

Cracks at the edge of a deck may indicate a more serious issue underneath.
Further evaluation is recommended.

2.) Rusted metal flashings on deck edges or at deck to wall areas. Rusted areas in field of deck. Rusted railing bases.

Rusted railing bases have lost their strength and now may present a hazard
as they won't be able to retrain you from falling. An inspection and fast repairs
need to be done in many cases to maintain safety. 

Any type of plant growth around a railing bases indicates moisture
conditions underneath. 

Rust on the metal flashing like this is a sign that further inspection
should be done and a scope of work written.

3.) Ponding Water. After a rain storm, your waterproof deck should be dry within 24 hours to at most 48 hours. Water should not ever pond longer than that. An inspection of the problem areas can help you determine what work can and needs to be done to correct a ponding water issue.

Ponds in the middle of a walkway always create problems.

Water sitting at the wall can attack exposed sheet metal causing rust and leaks.

Water sitting on an edge indicates a high edge. 

Watch for future articles discussing drains and scuppers.

Westcoat Buys Mer-Kote Brand From Parex

Westcoat announces acquisition of the Mer-ko brand – Weather Deck and Shur Deck to be Featured Systems

Westcoat is pleased to announce the purchase of the Mer-Ko brand from parent company Parex. The purchase agreement, signed April 16, 2015, certifies Westcoat receiving full and exclusive rights to the Mer-Ko name and its two premier waterproof decking systems.

Mer-Ko, one of the original manufacturers of waterproofing systems has been producing widely used elastomeric deck coatings, waterproof membrane systems and underlayments since the mid-80s. Mer-Ko’s two primary systems, Weather Deck and Shur Deck will be re-introduced to the industry with wide-ranging manufacturing and technical support by Westcoat.

Weather Deck is a pedestrian walking deck system incorporating floating slip-sheet technology designed to isolate the waterproofing membrane and seamless decking from the substrate. This high performance system design eliminates concerns related to cracking and surface imperfections and offers superior durability.

Shur Deck is a metal lath reinforced walking deck and flat roof top deck system designed for use over plywood or concrete substrates. Shur Deck provides long-term durability and waterproofing protection using a latex modified polymer mortar to prevent cracking.

“Mer-Ko has always been a key player in the waterproof coatings industry with a loyal following,” said Paul Koury, president of Westcoat. “We couldn’t be more pleased to take ownership of the Mer-Ko brand and re-instill faith in the performance and longevity of their core systems. Our team intends to provide the same high level of quality control, technical support and customer service expected and experienced when doing business with Westcoat.”

Mer-Ko is available through U. S. distributors in the waterproofing, specialty coating business. For sales inquiries, contact Dean Jarmusch at 84

Architects, General Contractors & Pest Control Technicians Have Little Understanding of Waterproofing, Why Does Berkeley Want Them to Inspect Decks Then?

On June 24th I wrote a detailed letter to the City of Berkeley's Building Department, City Manager and City Solicitor regarding their memorandum of proposed changes to the Cities Building Codes.

They want to implement various changes related to the construction of and methods of waterproofing balconies, along with requiring inspections of decks and balconies on apartment complexes and condominiums, While their proposed changes are well intentioned, some of them are a little crazy in my opinion.

My biggest objection is having Architects, General Contractors and Pest Control Technicians inspecting decks...why do I say that?

Read my letter and leave a comment telling me what you think!

June 24, 2015

City of Berkeley

Mr. Eric Angstadt, Christine Daniel, Zach Cowan

Building & Safety Department

2120 Milvia Street

Berkeley CA 94704

Dear Mr. Angstadt, Ms Daniel and Mr Cowan,

Let me first say that I am deeply sorry and anguished over the tragedy that occurred last week with the deaths and injuries to thirteen people. I cannot fathom the sorrow that the bereaved parents and families must be experiencing.

My background includes six years as an estimator/sales person for several large deck waterproofing companies doing business in the San Diego/LA/Orange County/Ventura/San Luis Obispo areas, as well as being a CSLB licensed (currently inactive) waterproofing contractor for seven years. I am now a consultant and perform deck inspections for real estate transactions and for HOA's. I have sold and installed hundreds of thousands of square feet of deck systems in my career.

I have been one of the experts used by several media sources for comments and opinions on the causes of the deck failure. As owner of DeckExpert.com I promote the use of Pedestrian Traffic Coatings at our website of the same name for use on balconies, stairs, roof decks and walkways. Pedestrian Traffic Coatings are walkable waterproof membranes typically used on decks, stairs and balconies covered with plywood decking and these are also listed and evaluated as roof assemblies for low slope roofs. These membranes are listed in ICC-ES' website under Division Seven Thermal and Moisture protection under 07 18 13.

I would like to take a few moments of your time to lay out my recommendations that the City of Berkeley should consider implementing to avoid another tragedy in the future. I understand that there are several recommendations already in the works, and I would hope you will consider incorporating my recommendations as well.

As you know already, the deck that failed appeared to have a Grace 3000 bituthene membrane as it's waterproofing, covered with a topping slab of concrete. Basically this is the same as a plaza deck, found over below grade parking structures with the living units built using wood framed construction. These plaza type decks must be carefully assembled as once covered with a topping slab, the waterproofing is impossible to inspect or repair without removal of the topping slab. Plaza decks must have a subsurface drain system in place to deal with water that is bound to get under the topping slab.

Plaza decks in my opinion and experience have had many problems with their assemblies in the past, due to the technical skill necessary and the usual lack of skilled labor who understands how to assemble them. I believe that these types of assemblies should be banned from use on top of wood framed and plywood covered decks.

1. In lieu of plaza deck assemblies, I would instead propose that the City of Berkeley consider implementing a requirement that only pedestrian traffic coatings be used on plywood covered decks. The main reason for this is that pedestrian traffic coatings are “an all in one” solution to waterproofing these decks while providing a walkable surface at the same time. They can be easily inspected and are relatively easy to repair if damaged. Most Division Seven Pedestrian Traffic Coatings are also Class A roof rated systems (ASTM E-108) and many are also rated as One Hour assemblies (ASTM E-119), therefore meeting the Cities fire resistant requirements. Many of these systems can be finished in any number of ways with texture and pigmented sealer as well as stained/stamped etc to look like tile, stone, wood etc. There are several different system types available, leaving architects and specifiers choices among concrete based coatings, liquid applied coating, slip sheet systems and sheet goods. Concrete and many of these coatings can also be used to correct deficient slope conditions, so achieving a 1/4” slope per foot is very easy to do on flat decks that were not framed with slope in them.
2. In regards to the Berkeley Building Code changes proposed, I concur with the recommendation to require Ventilation of weather exposed enclosed assemblies under Section 1203.6. Most of our manufacturer's already require this in their general requirements in their CSI specifications. I also concur with the inclusion of access panels on the underside for inspection of the framing.
3. In regards to adding Section 1404.13 Projections exposed to weather, after consideration, I concur with using pressure treated wood or steel for framing the deck. I do believe that properly waterproofed, conventional douglas fir framing is perfectly suitable for the framing, however, rot resistant materials will certainly perform better if exposed to water over a longer period of time.
4. Under Section 2304.11.4.2 Wood structural members, I propose that the City eliminate the use of moisture permeable floors or roofs such as concrete or masonry slabs. My reasoning is that these types of assemblies trap water in them and as they are typically part of a plaza type deck system, are not conducive to using them on balconies covered in plywood anyway.
5. Regarding adding Section 601.4 Structural Maintenance; I concur with requiring inspections. I have several changes to propose; these being requiring inspections every two years instead of the proposed five year interval. In my experience as a waterproofing contractor and consultant, five years is to long between inspections. A lot of serious damage can occur in a short time. Manufacturer's of Pedestrian Traffic Coatings require as part of their warranty that their systems be inspected yearly. Regarding who should inspect the decks-waterproofing is a specialty trade. In my work as an educator, I usually have a room full of people where 90% or more are general contractors. General contractors are just that, generalists. I've found in my experience that most do not understand waterproofing in general and decks in particular. While structural pest control licensees know the signs of dry-rot, wood destroying organism infestations etc, they do not understand waterproofing either. Engineers and architects are generally familiar with waterproofing concepts and can certainly recognize inherent defects and issues with contiguous building materials and would be suitable candidates to perform inspections. I believe the best candidates to perform deck waterproofing inspections are waterproofing consultants. As a group, we are very familiar with installing and maintaining waterproofed decks and balconies. It may sound self-serving and I appreciate anyone thinking that it is, however, as an example, I've spent nearly 14 years as an estimator and owner and applicator of a firm specializing in waterproof deck installations. I've found that many of my peers were applicators and as we “age” out of being able to work on our hands and knees we seem to transition into consulting and inspecting. The Roof Consultants Institute (RCI) and Sealant Waterproofing Roofing Institute (SWRI) are two organizations that are focused on roofs, decks and waterproofing systems and are probably best qualified to do such inspections. We have familiarity with general building requirements and understand the importance of contiguous building materials needing to be weather resistant as well.
6. I would suggest that the City add the following requirements for deck waterproofing; these being that building inspectors begin inspecting the waterproofing of the decks as it's being installed, including inspecting the flashing system and substrate prior to covering with a membrane. Most importantly, inspectors should verify that the deck is sloped or tag the deck so that it will be sloped and they can check the slope before signing off and allowing finish coats to be installed. Once the membrane is installed, but before it is decoratively finished, it be inspected again. As part of the requirements, the City should allow only ICC-ES pedestrian traffic coatings with Class A ratings minimum and One Hour where already required. The ICC-ES report should be made part of the submittal for building permit approvals.
7. Regarding substrate-the use of Oriented Strand Board (OSB) for pedestrian traffic coatings is not accepted by ICC-ES nor any manufacturer. All fire testing is performed using plywood only. OSB, in my experience, despite the claims by manufacturer's that it's better at water resistance, is a sponge. I've seen OSB expand and it doesn't return to it's original dimensions. Therefore, OSB should be banned for use on decks and plywood be the only acceptable substrate allowed. I would caution against requiring pressure treated plywood, mechanical fasteners used on some systems may not be compatible and liquid applied coatings may have issues as well with compatibility.
8. Regarding railings-steel/aluminum railings that mount onto the deck should be banned. In my experience I've found that it is impossible to guarantee a waterproof deck won't leak when railings penetrate the waterproofing. Only metal railings that mount to the fascia should be allowed. Wood 4x4 posts penetrating through the plywood and bolted to the deck framing can be flashed and waterproofed. The key in waterproofing these wood posts is that they MUST be wrapped with bituthene/Tyvek/building paper and then either boxed in for a final finish or a post sleeve, typically made of plastic/synthetic materials is slipped over and finished on top with a decorative “hip roof” style cap to shed water.

As a general note, it is contained within the CBC 1998 code 1402.2 that openings in exterior walls are required to be flashed in such a manner as to make the opening weatherproof. For waterproofing purposes on decks, metal flashings, be they galvanized steel, copper or stainless steel, are meant for the purpose of terminating our coatings to. All deck waterproofing systems must be run up the vertical leg of the flashing so that contiguous building materials are installed down over the flashing, forming a weather resistant barrier. Counter-flashings, be they Z bar or weep screed for stucco provide the mechanism for water to be shed off and away from the buildings interior.

Furthermore, as a general note, building inspectors and the building department must ensure that proper weather resistant barriers meant to waterproof the decks, the building and the foundation are specified and installed properly. These systems are just as, if not more important to long term comfort, use and enjoyment of the building than framing, mechanical and electrical systems. Inspectors should be required to closely inspect all weather resistant barriers, including siding, windows, doors, foundation waterproofing and the decks and roofs to ensure they meet or exceed code requirements.

I sincerely appreciate your concern in wanting to strengthen and improve building codes and requirements for the safety and security of occupants. I hope these recommendations will be considered and implemented. I am willing and able to appear in front of any panel, council meeting or with the building departments staff to discuss these recommendations. Please let me know if you would like me to appear to testify/discuss.

Sincerely,

William Leys  

New San Francisco Chronicle Article Reports Witnesses Say Balcony That Failed in Berkeley Had "Unusual Slope"

Award winning reporter Jason Van Derbeken in his latest article reporting on the Berkeley deck tragedy reports-

"Attorneys representing the family of a Berkeley balcony collapse victim have contacted prosecutors to alert them to witness accounts that the deck had a “seemingly unusual slope” before it gave way during a party."

Decks are required to have a minimum of 2 percent slope to them do water will drain of and away from the building. If the deck pitches much more than 3 or 4 percent, anyone standing on the deck will feel like they are being pitched forward and will have to make adjustments to their posture, but will remain uncomfortable. Imagine walking down a steep hill; it's not comfortable and you make adjustments in your gait and posture.

The same feeling will occur on a deck with a high degree of slope on it. To me this indicates a warning sign of problems in the deck. It wouldn't necessarily indicate that the deck was ready to fall, but I would, if I was inspecting a balcony with that condition, raise a red flag.

Deadly Berkeley Balcony Collapse - Poor Design, Poor Workmanship in Installation

The six people that died and seven who were seriously injured in the balcony collapse on an apartment building on Kittridge St in Berkeley CA never should have died or been injured. That's my opinion, based on the information and documents I've received and photograph's I've reviewed.

Eventually a jury or a mediator will award the dead and injured money to compensate them. Who will pay and how much they will pay will be the only question.

Broken off joists from dryrot due to water intrusion.
Decks must be pre-sloped, then waterproofed. 

From what my review and discussions with other experts have come up with, the wood cantilevered deck was framed out flat, despite the plans calling for a 2% slope on it. After being built, it was waterproofed using Grace 3000 bithuthene membrane, a peel and stick waterproofing sheet good.

Grace 3000 waterproofing system on horizontal surfaces
requires the use of a sub-surface drainage membrane under the concrete
overburden to allow water to escape unimpeded. 

Waterproofing detail for deck shows Grace 3000 bituthene membrane
but the drawing FAILS to include Grace Hydroduct 660 Drainage Membrane.
We presume water WILL get under concrete overburden and will need a way
 to drain sub-surface water out

After being waterproofed, it appears that sloping materials in the form of concrete backer board type materials were placed on top, then screwed down through the waterproofing membrane. Grace advertises that their membrane is "self healing" but also advises that any penetrations be patched. Near impossible to do in this type of situation. But someone probably thought hey it's self sealing so no problem screwing through it.

Apparently no further waterproofing over the sloped materials was done.

Then a concrete deck was poured over this assembly. Water will leak through concrete. It's permeable unless it's waterproofed. Stucco was applied as the finish under the balcony. One design flaw with the stucco was that no vents were installed on the underside of the deck.

Clearly there are no vent strips on the underside of the stucco covered deck. 

My theory is that water got through the concrete and in at the door area. The fasteners used to screw the concrete board down allowed water to penetrate to the waterproofing membrane. As screws rusted, they provided a channel for water to penetrate into the deck substrate and framing. Now with the wood wet, dryrot could begin.

This pic clearly shows the joists of the deck in a rotted condition.

Now I want to be clear, the design of the waterproofing appears to have been a problem too. I've reviewed details of the waterproofing assembly and the architect appears to have left out on critical piece of the system assembly-subsurface drainage. 

The Grace 3000, like nearly every Grace waterproofing product, requires a drain board assembly to be placed on top of the waterproofing membrane over a pre-sloped substrate. Without the ability to drain water out, concrete will hold the water against the waterproofing membrane, allowing it to sit, especially on a flat deck. The Grace system, if properly designed and assembled, should have worked for years and years without issue. 

So a flat deck, with waterproofing on it without slope, allows water to sit on it under the concrete overburden. Theoretically this deck as it began to deteriorate. My question then becomes, were the decks at the property ever inspected by the management company or a building evaluation specialist? My reason for asking is I would think that some signs of distress may have been present and noticeable to an expert. I say this because experts inspected the other decks on this property and determined several were dangerous and were red-tagged. Therefore it's reasonable to assume this deck, had it been inspected, could have been found to be dangerous before this tragedy happened. 

The lawyers will figure it out, the insurance company will pay out and we as a industry in building and protecting occupants, must become better at our trades, in both design and assembly. Someone has to own their work and take pride in it and do it right. 

We can't afford cheap construction.  

Gas Grill Propane Tank Explodes on a Deck, Resulting Fire Burns Everything

Once again tragedy strikes when attempting to cook with a grill on a deck...

From South Washington County Bulletin- "Two Woodbury senior citizens lost their home and they're lucky to be alive after the propane tank on their grill exploded on the deck last Wednesday. 
Robert Hamer and his wife, Katherine, escaped via the front door of their home in the 5700 block of Fawn Trail Circle, spending the night at a neighbor's house after a shocking accident on their backyard deck turned the $340,000 home into an inferno."

A woman was trying to move a barbecue away from the home when it tipped over and flared, causing fire to spread to the deck and the back of the house, said Peter Andrews, a division commander with Halifax Regional Fire & Emergency.

No one was inside the home at the time.

“It was quite a spectacular fire when our crews got there,” Andrews said Thursday night. “The house was fully involved from the deck right up to the roofline because the siding and the Styrofoam underneath it are quite flammable.

Check Your Deck® During Deck Safety Month® in May

QUAKERTOWN, PA – Your deck is the perfect place to enjoy warm weather with friends and loved ones. However, a poorly maintained or unsafe deck could possibly collapse, causing serious injuries to you and your guests. During Deck Safety Month^® in May, experts at the North American Deck and Railing Association (NADRA) recommend homeowners Check Your Deck^® before starting to plan family activities.
“Our number one priority and message to the public is to ensure that the decks they use are safe,” says Michael Beaudry, executive vice president of NADRA. “Outdoor structures like decks are exposed to sun, rain, snow and extreme temperature changes over the years. The need to maintain and inspect them is critical for keeping decks strong and safe.”

NADRA has created campaigns and educational programs, along with certifications for home inspectors, deck builders, remodelers, builders, code officials, engineers, architects, distributors, lumberyards and manufacturers to improve proper installation practices. The organization has also developed checklists and safety awareness information for consumers to assure they have details available to them to evaluate their decks. The information can be found HERE.

With an estimated 40 million residential and 10 million commercial decks in the United States that are more than 20-30 years old, it’s important for homeowners to check their deck on a yearly basis.

Consumer Checklist

A key element to enjoying your deck for years to come is making sure it is safe and code compliant. NADRA’s “10-Point Consumer Safety Checklist” is an efficient way to take a good look at the different parts of your deck, with an eye to what might need maintenance, repair or replacement. The checklist can be found at http://bit.ly/NADRA10PointConsumerChecklist.

Homeowners should consider a professional deck inspection. “A professional inspector will thoroughly examine your deck, provide information on your deck’s capacity limits, identify any dangerous problem areas and give you some insight of what to keep your eye on in the future,” says Beaudry. “NADRA provides industry professionals with a Deck Evaluation Form that is available HERE.

Older decks require closer scrutiny and regular inspections. Many decks were built before code requirements were established to protect consumers. Some of these older decks may have deck-to-house attachments using only nails instead of the current recommended construction using deck tension hardware that greatly helps in the prevention of ledger failures.

“We recommend ASHI-certified home inspectors or a knowledgeable deck builder for inspections of older decks,” says Beaudry. “Our NADRA member deck builders are required to adhere to a code of ethics and comply with state licensing and insurance requirements. This brings peace of mind to homeowners using our NADRA members.”

Deck inspection requires special knowledge, expertise and experience. NADRA offers training and certification for its members along with ASHI home inspectors and others interested in professional deck inspection. For additional information on NADRA certification classes, click HERE.

The North American Deck and Railing Association (NADRA) is dedicated to increasing public awareness of the necessity for regular inspection and maintenance of existing decks and proper installation of new decks. For more information visit www.NADRA.org
