There are two ways to install roll roofing on a low slope roof: overlap and nailing. Overlapping the roofing material ensures that the entire surface is covered and that rain does not get through the seams. To install the roll roofing, use roofing cement to secure the nails and adhere the roll roofing to the roof sheathing. Afterwards, cut the excess rolled roofing with a razor knife. Mark 35 inches from the bottom edge of the roof sheathing.
If you are installing roll roofing on a low slope roof, make sure you set a chalk line at the seams to relax the curl. You can then nail the first layer of roll roofing to the roof sheathing. Next, use a hammer to drive the nails into place. Once the first layer is in place, you can nail the next layer of roll roofing down. To install a second layer of roll roofing, measure 32 inches from the first and nail it down. Once you have installed the first layer, you can use the same process but apply lap cement on the roof deck to seal the seams.
If you want to install rolled roofing on a low slope roof, you must know how to properly install it. First, you need to prepare the roof sheathing. It may be primed or not. Make sure that the roof is smooth and level before applying the roofing material. After that, you will need several tools. For this task, you need a ladder, roofing cement, paintbrush, caulk gun, hammer, and nails.
You should mark the end of the first row with a chalk line, which should be approximately 35 inches from the bottom edge of the roof. Next, you should use a meter stick to make sure that your line is straight. After that, you can begin applying roofing cement. Wear gloves while working with roofing cement. Spread the cement out until it reaches the chalk line. Next, you should apply the cement to the horizontal section, which will be the first layer of roll roofing.
One of the advantages of roll roofing is its ease of installation. Since it goes down quickly, it can be rolled out in minutes. Professional roofers use a crane or forklift to install this type of roof covering. But do-it-yourselfers can also move the rolled roofing by hand. Unlike hammer-down rolled roofing, there is no need to use heavy machinery to install roll roofing on low slope roofs.
Depending on the type of roll roofing you choose, you may want to install an underlay before installing the shingles or rolls. Although it is not a mandatory requirement, it adds protection and helps keep the roof from buckling and wrinkling. A minimum slope of three units vertically and twelve horizontally, or 25 percent, is required for metal roofs. To make sure that you get the best installation, measure the slope of your roof.
