Granules are made from mined rock that has been crushed. To protect against wind and hail damage the sheet is covered with a strip of sealant. Nail the shingles with no tabs such as precut pro start shingles and apply asphalt cement from a caulk gun in many dots along the drip edge under the edge then press the tab less shingles down onto the line of asphalt cement dots with adequate spaces between the dots. Typically 10 by 8 inch 253 mm x 203 mm flashing is chosen.

For example 3 tab shingles usually have a 5 5 8 inch 143 mm exposure. There are some simple techniques to follow when attempting this project. Attach and align shingles to attach a 3 tab shingle align it with the layout line and drive nails 1 2 inch above the cutout slots including the half slots at each side. A continuous bead of asphalt could trap condensation or windblown water under the roofing at some point.

Understand the physics of how a sloped shingle roof works. Cut your last shingle on each row to size repeating all the way to the ridge. Once you ve reached the ridge bend the shingle over the ridge so that each side is equal and nail it into place with a single nail on each side. Make sure this row has a slight overhang 1 4 to 3 8 in beyond the drip edge.
