how much danger in 10+ roof layers?
I'm a handyman, not a roofer. I recently was hired to reroof a patio cover attached to the back of a house. While doing the job, I discovered the main house has nearly 2 inches of roofing material on it. I can't get an exact count, but I'd say it had at least 10 layers of roofing on it. The last time it was roofed was over 5 years ago.
I know this is not good. It probably doesn't help that part of the house has vaulted ceilings, which means there is no support for the rafters except at the walls and at the top. I can see the boards that support the roofing material have a slight sag between each rafter.
I want to know how much "fear" to instill in the home owner as to his current situation. If his roof is in danger of failing, I want to be sure he understands this.
Thanks for any replies!!
