When you install shingles over an old layer of shingles do you have to put down felt or do you put the new layer of shingles directly over the old layer?

With composition shingles, no felt is necessary between shingle layers. When the exposure of the shingles is the same as the old exposure, the bottom edge of the old shingles is used as a guide for the upper edge of the new shingles in placement. This ability to place the shingles would be lost if covered with felt.

Can you install dimensional shingles over dimensional shingles?
Any time you layer on top of existing shingles you cut down the life span of the new roof. (Roof gets hotter and so the materials deteriorate faster.) So you may be able to do it (check local codes) but it isn't advisable. If you're looking to save, you may be able to do the tear-off yourself.

Why should you remove the old tar paper when you put on a new roof?
yes, i am not trying to sound like a smart alek but if you don't know the answer please seek advice from a professional roofer you will be better off in the long run. ================== Check with the info on your shingles, some recommend NOT putting down tar paper first others go as far as voiding the warranty if you do install them over tar paper. Personally, I would not put shingles on my own house without tarpaper, it is a cheap and fast extra layer of protection from water that can cause a lot of damage sometimes before you can see it.

Absolutely NOT! Shingles are caused from a similar virus to what causes chicken pox. A vegan generally is going to have a very strong immune system, so would be no more likely, and potentially even less likely to come down with shingles.
