Asphalt Shingles Underlayment Asphalt Saturated Organic Roofing Coiled Roll
Introduction
Asphalt saturated organic roofing felt is a felt paper that is soaked in asphalt and other water resistant compounds to produce a membrane.
It is widely accepted as underlayment under asphalt shingles, forming a secondary waterproof level. For decades, roofers have been installing felt paper as underlayment when replacing roofs. Felt is time-tested and approved as a viable option with most residential roofing systems. Felt is commonly sold in either 15# or 30# rolls measuring 36inches wide.
Reasons to use felt paper:
1. Water resistance.
2. Protection from resins in the decking that can be damaging the asphalt shingles.
3. Vapor protection.
4. Temporary protection in the event of storm damage.
