Red Rosin only as underlayment | Ask The Experts Forum

Guest User 5/10/2010	I am roofing a 12x8 storage shed with dimensional shingles due to subdivision covenant. Anyway, it is my first go at it. When I went to the improvement place to buy shingles I looked at the felt paper rolls and saw that they were way more material than I needed. i also saw the red rosin. The associate seemed to think that using this instead of the felt paper would be fine for a shed. So I have attached just the red rosin and have installed most of the shingles on top of it. Have I made a mistake by not also using felt or will it probably be okay?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14735/find/

As long as they don't leak, you will be okay. Remember that asphalt shingles do absorb and release moisture so you may see some red staining.
