What is the max temperature for putting down roof shingles?


It takes a combination of atmospheric temperature and radiant heating combined with the roof slope to cause this to be a concern.  So 80 degrees and high sun on a 6:12 pitch might yield conditions that are no longer conducive for shingle installation.  A cloudy 95 degree day may be just fine.

In general, if the foot traffic on the shingles is resulting in the granules being disturbed and exposing the underlying asphalt, then the shingles are too hot and the work should stop.

hope this helps,
