Products needed to install roll roofing include galvanised roofing nails, roofing cement and underlay. A chalk line, tape measure and utility knife are handy for the project as well. Roll roofing bends and cracks easily in cold weather, so avoid installing it in such conditions.Continue Reading
To install roll roofing, lay an underlay on the roof, smooth the underlay, and secure it with tacks. Measure and mark several 35-inch intervals from the point of the roof that meets the building. Snap a chalk line to act as a guide for laying the roll, and roll out the first sheet, making sure it is smooth and even. Apply a 2-inch layer of cement under each side of the sheet, and use a hammer to nail it down across the bottom edge.
Once you have rolled the first sheet, apply a 2-inch layer of cement on the top, and nail down the second row. Secure the remaining rows of the roofing in a similar manner, overlapping the vertical seams by 6 inches and horizontal seams by 2 inches. Be sure to apply cement on all of the seams and overlaps, and leave 1 inch of overhang on either side. Roof the hips and ridges, and cut away extra overhang with a utility knife.Learn more about Carpentry
