Replacing shingles

June 19th 2001

Question from: Carla

Dear Shell,

Can you use plastic (heavy) in place of roofing paper when replacing shingles on roof? If not why?

Thanks, Carla

Dear Carla,

Absolutely not Never use plastic over a roof deck before applying roofing shingles. This will harbor moisture. Why? Your roof structure must have a breathing feature: tar paper will give you that feature. Use minimum #15 felt over entire area before applying shingles.

Its just that easy.
