Roofing Felt underlayment
Felt underlayment is an essential part of a roofing system and helps protect your roof from the elements. It acts as a barrier between the roof deck and the shingles, preventing water from seeping in and causing rot and damage.
The felt also helps reduce noise, adds insulation, and provides additional protection against wind-driven rain. Additionally, it helps keep shingles in place by providing a uniform surface for them to be attached to.
Felt underlayment is an essential part of a quality roof that will last for years to come.
Best practices to use an underlayment in roofing
- Ensure the roof deck is dry and free from debris before installing underlayment.
- Start installing the underlayment from the eaves and work your way up to the ridge.
- When installing the underlayment, overlap the edges by at least 4 inches.
- Secure the underlayment to the roof deck with staples or nails.
- When installing near valleys or around roof penetrations, use a tar roofing cement to seal the seams.
- Install an ice and water shield along the eaves and in any areas where there is potential for ice dams.
- Install an appropriate number of roof vents to allow for proper air circulation and attic ventilation.
- Make sure to follow all local building codes and manufacturer instructions when installing an underlayment.
