CNewhouse Posted October 26, 2021 Report Share Posted October 26, 2021 My inspection today had a modified bitumen roof. I don't see product this often, aside from the occasional neglected detached garage. Reading through a few installation manuals made me realize how many different application options there are. The roofing today had no bitumen squeeze out at the overlapping seams, which had me thinking that the bitumen wasn't properly heated before being applied. Could it be that this is a self adhesive membrane, hence the lack of squeeze out? The end laps were very poorly adhered and lacked proper offset and the flashing details were a bit screwy so I recommended a roofer take a peek either way, but I'm curious how one knows which application method the "roofer" was attempting to apply.
