All the roofers I spoke to and received estimates from said if I wanted to save money I should simply do a layover. This is what I was looking to do because the roof was only 12 years old and other than the moss growing all over it, it didn’t look too bad. Then my last estimate came from Rep. Mark from Exclusive Roofing Inc. I told him I was considering a layover and the first thing he said was “what condition is the decking in?” I said “I guess it’s fine why?” To make a long story short, Mark was the only person to actually inspect my loft and boy am I glad he did. Not only was the plywood completely delaminated and weak but I had moisture in the deck that had spouted black mold all over it. I wasn’t happy about the extra cost to strip off the old deck, but I have piece of mind that the job is now 100%. If I had chosen another roofer I might still be living with a moldy weakened roof. Thank’s “Exclusive” for hiring such a knowledgable nice guy.
