The asphalt shingle roof is the most popular type of Atlanta roofing. Cost-effective and relatively easy to maintain, a good roof made of asphalt shingles can provide you with years of dependable service. Eventually, however, shingles wear down. They shed their granules, curl up at the ends, and even come loose. When this happens, the only solution is to replace your roof. If you’ve never installed asphalt shingles before, here are a few tips on how to go about it.
You can’t install new shingles without removing the old ones first. Using a garden fork or roofing shovel, pull them off one by one, starting at the point furthest from the trash container or wherever you intend to discard the old shingles. Lean a piece of plywood against the side of the house where you’re working. This will protect the siding and windows from errant tiles or tools. While you’re at it, pry up all the nails and ridge caps you find and remove the flashing around the chimney, vents, and any other protrusions in the roof. After everything’s been removed, sweep the roof and take the opportunity to pull out any nails or anything else you might have missed.
Before the tiles can be installed, you’ll need to lay the underlayment first. Many roofers prefer 15-lb roofing paper, but a self-sealing membrane with a rain screen provides better protection from wet Atlanta weather. Overlapping each row at least three inches, generously staple the underlayment to the roof deck. In valleys in the roof or places where the roof meets a wall, install sticky back ice and water shield to prevent the buildup of ice, leaf, and twig dams. Finally, install the new flashing around the chimney, vents, and walls.
Before installing can proceed, you might want to make a chalk guideline to simplify the process. Basing your measurements on the width of the shingles you’re using, outline at least four rows across the roof. To make sure you’ve got the right size three-tab shingles for laying rows (courses) correctly, you’ll need to cut the shingles you’ve purchased into several different sizes. Cutting off one half tab-width from the first course’s tabs, continue cutting an additional 1/2 tab from each succeeding course so that each slot is 1/2 tab away from aligning with the courses above and below each shingle. When installing the shingles, hammer one nail approximately two inches from each end, and adding an additional nail one inch above each of the cutouts. As you apply further shingles, you’ll want to cover the nails one inch vertically, while horizontally, your end nails should be concealed by about half a tab. When you reach the end of each course, you’ll have an uneven space, so you should measure the amount of roof you’ll need to fill so you can cut an appropriately sized shingle to complete the course.
