[quote=“firstname.lastname@example.org”]I have alot of tabs that are worn clean through. If I do recover , do I need to place felt down first, or can I just put shingle on top of shingle? do I need a construction permit?
Thanks You guys, This is really helpfull.
I just went through this situation last week the people have a 300,000 dollar home and with 30 yr architects that are fading and couple tabs missing. They insist on a lay over but fail to understand that it would not last as long due to moisture would start to deteriorate the shingles at a faster rate and if you do the layover and have to do it again it will be much more expensive to tear off two layers. Lay overs in my opinion are not industry standard in my book just accepted by people who want to save money. I have done a few but I am very reluctant and quite frankly you leaving the old shingles will not save you as much as it will cost you in the long haul. Please highly consider stripping the old layer off before installing brand new shingles. What a waste but Ill consider if you highly insist. Hey its your money. No you do not use felt on layovers. On my estimates layovers are not much cheaper than tear off mainly because I dont like layovers.
