About Asphalt roof shingle installation

If your roof is missing shingles or if the shingles are cracked, broken or even just curling at the edges, you should consider installing new shingles. Replacing roofing is not a job for everybody - it's a heavy, tedious job and requires you to work off ladders and right up on the roof itself. However, shingling is not overly complicated, and it is a job homeowners can do themselves (or preferably with the help of two or three friends).

Shingles are sold in "squares" that cover an area of 100 square feet. An individual shingle is 36 inches long and 12 inches wide with tabs cut every 12 inches halfway through the width of each shingle. At the base of the tabs is a line of soft tar that will soften in the heat and help seal the shingles to the roof.
