Hey everyone I have a house that is 6600 sqf and has clay tiles on it, two roofers have already inspected it and say that there is 15 pound under the roof and the builder is saying there is 30 pound felt.
The two roofers say that the 15 pound felt should have never been used and has a high rate of failure.
Does anyone have any facts on this matter archived deep in there computers?
And has anyone seen any legal mumbo jumbo on the can or cannot’s on the use of 15lb felt on the underside?
Thanks in advance
