Good size wrinkles in new EPDM roof?


I have just had a flat rolled roof striped and EPDM applied in Boston MA. The roofer finished the job just prior to Tropical Storm Irene arriving. The roof appears to be watertight.

There are number of good size wrinkles in the EPDM.

Is this acceptable? Am I going to have premature leaking problems due to this?

Thank you.

Leakproof should not be the only measurable aspect of a properly installed roof.

I would not be happy with that finished product if it were my roof but I do not know what his contract states.

I think that this is not a problem.

The wrinkles will cause problems eventually, but so would cutting them out and patching the roof.

Thank you for your reply.

Do you have experience with this type of roof?

Does it remain flexible in the winter? Might the weight of ice and snow on it cause it to crack. Or, if I step on the wrinkles in winter while brushing snow off the roof will it crack at those wrinkles?

Thank you.

I think so too. Not sure since I never had a wrinkle problem. I do think that if you try sweeping snow off, cracked bones will be much more of an issue since wet EPDM can be awfully slick!
