Hi.

I want to apply a second rolled roof over another rolled roof and
would like some tips and opinions please. For me its economical and I
can do it myself.

I have a 12 x 18 3 season attached porched with black ashpalt rolled
roofing that is looking kind of shabby. It has some ashphalt coming
loose, but the basic roofing is intact. The ends are not curled, but
is looking thin from shoveling snow off of it, etc.

I would like to apply rolled ashphalt roofing that has a sticky
backing all over the undersurface. I used this stuff to roof a shed
and it seals everywhere and works great. I want to also add new drip
edges on sides and outside edge.

I plan to sweep current roof with stiff brush to remove all loose
material. Nail drip edge (about 3" wide stuff") on 3 sides. And on a
warm but not hot day, lay the new roof on the old about the same
position as the first starting from the outside and overlapping about
4 strips to cover eave of house the same as before.

Is this okay and will it work? Any tips, sugestions? Thanks.

Fred
