Synthetic Roofing Underlayment
Roofing underlayment is laid between the roofing shingles and the roof decking. This is done for Three reasons:
1. As a water barrier; preventing external water vapor or precipitation from percolating onto the roofing deck
2. Prevents parts of the shingles chemical mixture from leaking onto the roofing deck, causing expensive repairs
3. Acts as a secondary ambient barrier, reinforcing the purpose of heat and sound insulation
When laying your roofing underlayment, you may want to compare the differences and distinctions between Felt and synthetic underlayment. It is the subject of a lot of debate for roofing solutions in the determination of efficiency, cost and durability.
