Asphalt Roofing Problems

Repair

• When part of a shingle is missing, the best repair method is simply to replace the entire shingle. Try to find an extra shingle left over from when the roof was installed. If you don't have one, go to your local building supply and find the closest match. For shingles that start to curl, apply roofing sealant underneath the shingle, and place a brick on top for 24 hours. To repair a torn shingle, apply roofing sealant under the torn area and then on top of the damaged spot.

Removing Old shingles

• One difficult decision the average homeowner faces when putting on a new roof is whether to remove the old roof. You can often apply new asphalt shingles over old ones; however, home improvement expert Tim Carter recommends removing the old roofing material before laying down the new shingles. You can take advantage of having the roof deck exposed to repair or replace any decayed sheathing and to ensure all the nails and fasteners remain secure.

Keeping Shingles Plumb

• Use chalk lines, taut strings held down by nails, to guide you when you apply shingles. Place a chalk line down the center of the roof to help you center the starter course, a row of shingles with the bottom sections cut off. Setting up a horizontal chalk line that allows the first course to overhang the starter course by 1/4 inch keeps the shingles properly aligned, advises Tom Silva of This Old House. Continue to use chalk lines every 5 inches for horizontal lines and every 6 inches for vertical lines as you work your way up the roof.

Safety and Tips

• Installing an asphalt roof is a difficult task for the average homeowner. You may want to hire a professional. If you have above average handyman skills and decide to do the job yourself, get a friend or two to assist you. Investing in a pneumatic nail gun helps the work go faster. Place roof jacks, metal brackets with a hook on one end, to secure your footing. Although making minor repairs is not as difficult, always take the appropriate safety precautions.
