[quote=“jac99”]I talked to my contractor and he says everything I am worried about is just cosmetic, the roof won’t leak. Yes its going to last. If anything is going to leak, its going to leak in the first year and I have a 5 year warranty.
He said he will put granules on the uncovered black parts of the modified bitumen. I think with a torch. Is that a good idea on adhesive modified bitumen? How is that going to look?
He says the wrinkles are just cosmetic. They won’t hurt anything. No flat roof is wrinkle free. They may flatten out in the heat of the sun. He says they have used a roller.
The drip edge/drooping shingles are due to how the roof was built and he can’t fix that without rebuilding that part of the roof. He said something about the trusses. That was a small added on front porch so doesn’t surprise me if the construction was wrong. But my old 3 tab shingles didn’t droop like that. I added a before shot of my porch corner. Its not a great angle, but it shows the shingles were laying flat.
There is a layer of blue material stuck with adhesive to the plywood deck. On top of that is the weathered wood modified bitumen. There were certainly some waves and lumps in the plywood. Photos added of the blue material.
I added some more photos of the shingles since you mentioned them.
Thanks for your help.[/quote]
I wouldn’t use a torch on Self Adhered modified ever, for any reason.
The reason you are seeing part of the seam is because the seam is not lapped at spec, it’s too small.
Who wants to replace work they recently did?
The bottom line is that the modified is obviously improperly installed, a professional wouldn’t do that nor accept that work from the people under them.
Many of the posters on this forum install low slope roofing on a daily basis, with no wrinkles in it.
Occasionally we will get a small wrinkle, this is the exception rather than the rule.
Your roof has several large wrinkles.
