Firestone Clad-Gard MA
Firestone Clad-Gard MA (Mechanically Attached) Underlayment is easy to carry and easy to fasten. It is available in 10-square rolls that are 4' (1.2 m) wide. At only 31 lb (14 kg) per roll, Clad-Gard MA underlayment is much lighter than roofing felt. It lays flat and stays wrinkle free, so it needs fewer nails to stay fastened to the underlayment.
