Atlanta Roofing: Article About Roof Repairs
Atlanta roofing professionals have seen that many of their clients think that they need a new roof if they see a leak in the ceiling. While a ceiling leak may indicate a failing roofing system, a leak can sometimes be easily repaired. There are some signs that definitely point to needing a roof replacement.
One example of this is the age of a roof. Asphalt shingle roofs are designed to last between 20 and 25 years. Their longevity will change depending on ventilation and the number of shingle layers that are present. If there are multiple layers of shingles on the roof and the outer layer is more than 20 years old, it is likely that the roof needs to be replaced.
If shingles are bucking or they curl, this is another indication that a home may need a new roof. Curling and loss of granules will be more prominent on the south side of the home since it receives the most direct sunlight. When shingles lose their granules or when they curl, this is usually an indication that they have passed their life expectancy and need to be replaced. It could also be a sign that the roofing material used or the installation process used was defective.
Homeowners should pay special attention to the shingles that are in the valley of the roof.

A roof's valleys are the most important areas on the roof. They allow precipitation to travel to the gutters. If the shingles in the valley areas are damaged, it is likely that the roof will leak.
Another indication of a failing roof system is missing shingles and damage to the chimney flashing. Flashings that are made from roof cement or tar should be replaced with a watertight metal flashing system.
Shingles are made from a combination of fiberglass and asphalt. When a shiny gray or white color becomes visible on a shingle, it means that the outer layer of protection has fallen off and the fiberglass part of the shingle is showing.
Homeowners who have roofs that are younger than 20 years old but are exhibiting some of the above mentioned signs should speak to a roofing contractor and have their roof inspected. Things such as improper insulation, improper ridge vents, the accumulation of moist debris on the roof, and using off brand shingles may cause a roofing system to fail prematurely.
Taking steps to address roofing issues immediately is the best way to prevent long term roofing disasters from taking place.
