Buyer's guide
Single-Ply vs Built-Up Felt
Built-up felt is the legacy commercial flat-roof system — multiple layers, hot-bonded. Single-ply (PVC, TPO, FPO) is one engineered membrane, mechanically or adhered. Single-ply now dominates new commercial work for good reason.
- Single-ply: 25–30 year design life
- Built-up: 15–20 year life
- Single-ply faster to install and lighter
- Built-up still viable for short-term repair overlays
- Single-ply detailing requires manufacturer-trained installers
