About Air Compressors for Roofing
Coil roofing nailers typically draw 1.5–3 CFM. A pair of roofers sharing one compressor will need 4–6 CFM and a tank of at least 24L to avoid waiting for the pressure to rebuild.
Choose a wheeled portable with a steel rollcage, oil-lubricated belt-drive pump for site durability, and an electric start regulator that holds your nailer's exact pressure.
