Our HOA contracted to do several asphalt shingle roofs as part of a major multi-year re-roofing project for roofs at end of life. The contractor was apparently overcommitted, and did not start until November, despite being contracted and deposit paid in early September. He stripped off the old shingles in late October/early November, and dried in with underlayment, then left the roofs sitting for a month of good weather, only to show up and install the shingles in the rain and snow of late November.
As a result, much of the work was done in the cold (below 40 degrees) and rain and snowfall. At various points, they were installing shingles in the rain and/or blizzards. The underlayment was laid down in sub-40 degree weather, often on top of cold and damp (from rain, light snow, or frost) decking, without priming. And then the shingles were stored outdoors bent over the rook peak in overnight freezing weather, and were often installed first thing in the morning in the sub-40 degree (or worse) cold and even rain. The overnight temperatures often dropped down to well below freezing. The roofers worked on and walked across the underlayment extensively (both the ice shield and synthetic felt), while it was dripping wet.
So… I am not an expert on roofs, I am a Board member. These practices are clearly in violation of both the shingle and the underlayment manufacturers’ specs, as well as the consensus of all the best practices guides that I consulted which universally specify roofing above 40 and dry underlayment. But I have no way of evaluating how important an issue this really is, and what are the possible consequences of these practices over the lives of the roofs.
I don’t even know how we can accept the work now in December, since the shingles are all wavy and won’t adhere at earliest until late spring.
Some of the Board members don’t want to make a fuss. “Other contractors in our area shingle year round” they say. “Roofs are done in places like Seattle where it rains all the time” they say. “It’s a small town and we don’t want to get a bad reputation with the few roofing companies” they say. In the process of spending a half million dollars of other people’s money, I’d like to be more certain we can rely on the work and stand behind our due diligence.
I believe the products were WIP 100 ice shield, Grip-right synthetic underlayment, and GAP Timberline shingles. Our two-paragraph contract is no help, so our only recourse is via a warranty of workmanship.
Advice welcome. Thanks.
