I live in an older home, how long can a roof last?
If your roof is over 10 years old, you may want to look for other signs of trouble.
1. Algae Growth
Caused by growth of airborne algae deposited on roof. This does not affect the service life of the material. A common problem in warm, humid climates. Algae resistant shingles available regionally.
The bending and twisting of shingles can be caused by lack of ventilation. Can also be caused by improper number of fasteners.
Caused by moisture in shingles. Caused by excessive use of asphalt plastic cement.
4. Missing Shingles
Caused by improper fastening and, also, from exposure to high winds. This problem can usually be solved by replacing individual shingles.
Decaying shingles caused by absorption of moisture by mat at the core of the shingle. This is a common problem with organic-based shingles.
6. Missing Granules
Excessive loss of grains and particles in aging shingles indicates the need for replacement. On newly applied shingles, a certain number of loose granules is normal.
7. Damaged Flashing
Damage to the protective layer around the base of the chimney can be caused by drying and cracking, and, also, by improper installation. This can usually be repaired without replacing roof.
Several things contribute to warped shingles. Improperly applied felt, lack of ventilation and/or movement in deck can cause buckling.
9. Ceiling Spots
Dark water spots on the ceiling or in the roof are caused by leaks in the roofing system. Need to check roof for damaged shingles and attic/crawl space for leaks in deck. Look for cracks in flashing around chimney and vents. On rafters, check for leaks that travel away from original source.
What causes a roof to wear out?
All roofs over time deteriorate. Mother Nature, especially in the Southeastern US, puts many homes to the test with thunderstorms, wind, hail, and severe weather. Many local residents wonder how long do roofs last for Atlanta home owners?
The sun also greatly impacts a roof’s life expectancy. The asphalt used to hold the granules together on the fiberglass mat can deteriorate prematurely over time if exposed to direct sunlight.
The temperature extremes in your area; inadequate ventilation; exposure to wind, snow, ice and rain; hail and or wind damage can punish a roof.
If poor installation exists, such as the use of staples, too few nails in the shingles, high nailed shingles, inadequate/poor flashing, or nail holes, a roof can fail at any time.
What causes wood roof shingles to split and crack?
Splitting and cracking of the wood occurs naturally as part of the aging process, largely due to shrinking and swelling caused by moisture and subsequent drying.
Can an existing roof be covered with another?
Putting a roof over an older roof can be like putting a band aid on an infected cut. Unless the problems that the old roof has are known, covering them up might only delay problems from happening.
Additional roofs add a tremendous amount of weight to a roof and repairing or replacing a roof with additional layers can be costly, messy, and hard to troubleshoot.
In areas prone to heavy snowfall, strong winds or hail, or when an existing roof is wood or tile, overlay may not be appropriate. In some locales, when a composition roof is replaced, the roofer may not be able to apply the new material directly on the old layer, depending on its condition.
