Deck Expert recommends Quickflash Weatherproofing Products

In the mind to recommend a few products and try to reduce our headaches in the waterproofing industry; Quickflash Weatherproofing Products Inc manufactures a unique line of flashings that enable one to quickly and easily weatherproof plumbing, electrical, hvac and gas lines that penetrate exterior vertical wall penetrations.

So many times in new production homes that i worked on, a leak complaint centering on the deck area would come in and after extensive time inspecting our work, we would look at penetrations adjacent to our work and invariably there would be an electrical box or gas bbq line etc. nearby. Pour some water from a hose into the area and lo and behold, there'a a leak.

The picture shows a Quickflash electric box flashing. One would slip the building paper up underneath the bottom of the flange, then drop building paper down over the top, completing a weather shedding barrier.

Deck contractors should recommend to their contractors to use these products on their job-you'll reduce call backs on leak problems that weren't yours in the first place!

Sheet Metal Association Contractors (SMACNA) newlstter warns about deck coating and flashing problems

From a 2001 newsletter, still relevant today though...

Most Residential Construction Defect cases start as a result of actual leaks in roofs, walls, decks, doors or windows. Some cases get started as a result of a clever attorney convincing a homeowners’ association that they might have leaks later on. Regardless, if you did any exterior sheet metal work, they want you. Short of not doing that work, your best protection is to do it right and to document your work with photos and written correspondence concerning flashing details, including any and all suggestions you might make as to improving flashing, especially those buried in deck or hot-mop roof assemblies. If you see a bad detail in the plans, discuss it, document it, suggest your improvement and price it. Any documented rejections of this type of proposed improvement could be your ticket out of a lawsuit if that flashing is questioned later on. Also document with photos and correspondence any problems with the work of related trades that touch your work, i.e., roofing, siding, stucco, deck coating, windows and doors.
