Synthetic Underlayment
Lightweight, UV-stable, high-traction synthetic felt — safer to walk and longer open time than organic felt.
Haselton Lumber supplies synthetic roofing underlayment for use under shingles, metal roofing, and other roof systems.
Synthetic underlayment is commonly used because it is lightweight, durable, high-traction, and can provide longer exposure time than traditional felt, depending on the product.
Common uses include
- Shingle roofing
- Metal roofing
- Roof dry-in
- Steep-slope roofing
- Residential and light commercial projects
Underlayment selection depends on the roofing material, exposure conditions, manufacturer requirements, installer preference, and project schedule.
