A roof is the home’s primary source of protection from the elements, and as such, the homeowner should make sure it stays intact. However, like other shields, a roof has its weak spots, and there’s always the potential for failure. Whether a roofer is starting from scratch or repairing a home’s current roof, they should look for these signs of trouble.
A leak is one of the biggest roofing disasters, whether it’s in a poorly installed new roof or an older one. Leaks commonly occur at joints such as the one between the chimney and roof, and they can also happen at penetration points where flashing is used. When the roof is installed, the membrane should be sufficient and the seams should be solid.
Whether the roof has a high or a low pitch, it must be designed to prevent the collection of standing water, which can cause gradual degradation. Roofs should be installed with a very slight taper to prevent ponding, and drains should be kept clear to allow water to run off and away from the home.
To prevent blown-away shingles, the roofing contractor should look at areas such as those around pipes, chimneys and other penetration points. When the roof is newly installed, the seams should not be exposed to the elements until they are cured, or they might lift in the future.
Cracks and Punctures
An aging roof is more likely to be damaged by the weather. Punctures and other problems may occur when objects strike the roof, and leaks may not show until much later. Cracked and broken shingles can also cause leaks, and a contractor can inspect them annually for damage. Gutters should be cleaned regularly, and they should quickly remove water so it doesn’t stay in one place for too long.
Warping and Shrinking
Over the years, shingles can blister, buckle and curl. During the contractor’s annual inspection, he or she will look for indications of damage. As roofing warps and shrinks, it’s more likely to leak or come off during a storm. If the roof is severely damaged, part or all of it may need to be replaced.
Whether the owner needs a new roof or minor repairs, they can count on local contractors for help, inspections and advice. By looking for the above trouble signs, homeowners can protect their roof and their investment.
