I’ve read the Atlas shingle warranty from top to bottom and the one point that gives me pause is this:
SEALANT FEATURE: In order to activate the sealant feature, the shingles must be exposed to direct sunlight for a continued period of time for the shingles to seal. Shingles installed in fall or winter and not exposed to adequatesurface temperatures, or other conditions, which temporarily or permanently preclude activation of the sealant, may never seal and must be hand sealed at the time of installation. It is not a manufacturing defect if shingles fail to seal under the above circumstances, and Atlas will not be responsible for repair, replacement, or hand sealing shingles under these circumstances.
I assume this happens to all similarly made shingle brands? I also read that installation should be avoided with temperatures below 50F but that the shingles need to be warmed by radiant heat from the sun to about 70F to effectively seal. The question is, how long typically does it take for shingles to seal when temps are generally above 70 degrees? I’ve read that they can be hand sealed, but of course at an added cost. We’ll continue to have temps above 70 for several weeks I suspect but I’m not sure if that’s long enough? I haven’t the slightest clue.
