What is roll roofing?

Roll roofing is another asphalt roofing product much like asphalt shingles. Asphalt roofing rolls are common in residential roofing projects for flashings and underlayment. There are four basic types of roll roofing, each have their own best uses. Roofing codes in the state of Arizona do not allow for roll roofing to be used for flat roofs.

Roll roofing is an inexpensive roofing material that is used to cover low slope roofs.  A lot of DIY homeowners have used it and installed on top of a felt underlayment as a temporary roofing material. It has been used as the primary roof covering it is better used utility structures. The rolls are 36 inches wide and are typically sold as 36 feet in length. The common colors of the roll roofing are black, brown, and white. This material is sometimes referred to as 90 lbs felt by pro roofing companies as the weight of it is about 90 lbs.

The first types of roll roofing were made from felt canvas or sheets of cloth. These sheets were saturated with asphalt and then applied to low slope roofs. The long edge of the material was laid parallel to the eaves of the roof. Today 90 lbs asphalt roll roofing is made from either organic mat material or fiberglass reinforced mat. Both sides of the roll roofing are coated with asphalt and the exposed, or side that faces up is also coated with granules to protect it.

Roll Roof Installation

Single layer roll roofing typically has exposed nails with a 2 inch overlap between sheets.  To overcome the exposed nails many roofs are covered with a double layer of roll roofing. This means the nails are covered up under the lap joints that are in turn sealed with asphalt lap cement.  With a double layer of protection roll roofing can be used for small areas that are not flatter than 1:12 pitch.

Homeowners that want to do a DIY installation of this type of roofing should know the life expectancy of roll roofing. Due to the slopes roll roofing is used for the wear life is up to a decade, but many times can be as short as 5 years. This is because it gets “bald spots” or areas where the granules wear off from weather and the elements. If you can see these areas or areas where there are cracks you should know that the roofing is at the end of its useful life.

Mineral Surfaced

While this type of roofing is used as a primary roofing by itself it can also be a base under tile or shingle roofing. The top is imbedded with mineral granules that help increase durability. It also serves as roofing for secondary buildings like sheds, barns, and other outdoor structures.

Saturated Felt

The felt is asphalt impregnated and is an organic material. It has been used widely as underlayment between the roofing material and roof decking. For different types of installations the felt is sold in different weights, or thicknesses.

Smooth Surfaced

This type of roll roofing is used commonly at valleys, eaves, and to protect the roof decking. It can also be used to help protect protrusions, and roof line intersections. It is a smooth roofing material that is covered with mica or ground talc.

Eave Flashing Rolls

For colder climates or for superior eave flashing this is a specially designed material. It is self adhering, and made of a polymer-modified bituminous sheet. For places where water backup and ice damns this roofing helps protect the eaves from water penetrating the roof.
