Rolled roofing is made from the same material as asphalt shingles, but it is manufactured in rolls that range in width from 18 to 36 inches. While rolled roofing is relatively cheap and easy to install, its lifespan is much shorter than that of strip shingles. As a single-ply material, rolled roofing has a shorter life expectancy than shingles, which can last for 15 to 30 years. Because of this, the material should not be used in areas where heavy rain is common. roofing contractor
The life expectancy of a modified bitumen roof depends on several factors, including the architectural design, location and climate of your home. Although some manufacturers claim that rolled membrane roofing can last up to 20 years, this is unlikely to be true in Florida, where there is a lot of wind. In addition, a home with a lot of vegetation and high wind exposure may require continuous maintenance over time. Luckily, higher-sloped roofs shed water much more efficiently.
Rolled roofing is most common on low-slope roofs. Because it is inexpensive, many homeowners prefer it for their roofs. It can also be installed over #15 felt underlayment, which prevents water from leaking onto the roof deck. The best part about this type of roofing is its color variety. You can choose from black, white, brown, or brown rolls. Some roofers call it “90-pound felt.”
When installing rolled roofing, the first layer of rolls should overlap by four inches and should be nailed in place. The second sheet should overlap by four inches, and the third should overlap by the same amount. Then, place the second roll roofing course at 32 inches above the first course. Nailing them together is a good way to ensure a watertight layer. Once you have installed the first layer of roll roofing, it’s time to start installing the next one.
There are two main methods of installing rolled roofing. The first method is called exposed nailing, and it is used in industrial and agricultural roofs. The second method, the concealed nailing method, is more expensive and durable. In either case, it will take a couple of days to install the roof. It is easy to install rolled roofing with an exposed nailing system, but it will be harder to install it with a concealed nailing system.
The life span of rolled roofing depends on the material used. Asphalt shingles typically have a lifespan of five to fifteen years. At that point, deterioration becomes noticeable. However, some types of rolled roofing can last longer than others. One common type is self-adhesive roofing, which provides greater security and ease of installation. The self-adhesive material also requires less cleanup and is often faster to install.
Roll roofing is made of mineral surfaced oil-based asphalt. It is great for low-slope and flat roofs. One roll of rolled roofing is approximately 100 square feet in size. The material can be purchased at any home improvement store. Although rolled roofing is less durable than asphalt shingles, it can be found at most home improvement centers. It is also easy to install, and its advantages far outweigh the downsides.
