Comes with either a smooth or mineral-covered surface on a heavy felt base that has been saturated with asphalt and then coated on both sides with more asphalt.
Easy to install.
A typical roll roofing, known as 90-lb. granule-coated, will cover 100 square feet.
A 45-lb. smooth roofing, without granules, will also cover 100 square feet.
A properly applied roll roofing should last from 10 to 20 years.
