| AGDEAL - 9/17/2024 09:24 This morning the Gap was about half of yesterday afternoon. Cooler temps and out of sun. Builder didn’t install shingles but he did climb up and bend it down flat. Found another spot really bad that needs totally replaced. How much expansion is normal for those of you with roofing experience? Should drip have been butted up or overlapped?
Virtually no expansion, it's always nailed tight, and 1.5" overlap, never seen it buckle from heat. As said before, that was bent before it was installed. |
