How Do I Know When I Need A New Roof?

Old Shingles

Roofing materials such as asphalt, clay, wood and slate, do not last forever. Over time, there will be a lot of damage and wear and tear that will require a new roof. Asphalt roofing begins to deteriorate as soon as you install it because it is made of oil impregnated paper or fiberglass. The impact of the weather and the sun’s UV rays contributes to an asphalt roof’s deterioration. The following is a list of signs indicating that it may be time to get a new roof:

  1. Roof has reached end of its life: A typical roof like common asphalt will last between 8 and 15 years, depending on many factors that can accelerate the aging of shingles, such as the climate, type of roofing materials, and quality of installation. When a roof has aged, its quality and durability are greatly reduced. If your roof is near the end of its life within a few years, it is a good time to start considering a new roof.
  2. Moss and Mold Growth: Moss and mold can grow on shingles in moist and cool environments. This can be a sign of significant deterioration of the shingles. It can also be a sign of wood rot. Moss retains moisture against the roof surface and over time, in the cold weather, damage to the shingle granules will occur. Mildew is also a sign of deterioration.
  3. Noticeable Deterioration of Shingles: There are a number of signs of damage that are quite apparent with damaged shingles. These signs include: roof just looks old and worn, bald spots where granules are missing, cracked shingles, shingle edges are curled, dark streaks caused by airborne algae. All of these signs could mean the shingles are past their life expectancy.
  4. Roof Valleys: Shingles that are falling apart or missing is a definite sign a new roof is needed. Valleys are essential to a roof because rain and melted snow flow through valleys and into gutters. If the roof valley is deteriorated, roof leaks can develop.
  5. Spongy feel when walking on roof: When you walk on your roof and it feels spongy, it means there has been moisture that has weakened the underlying decking. Check for moisture in the insulation and if there is daylight coming through the roof boards when you look up from within the attic.
  6. Increase in Energy Bills: If your roof is not acting as an insulator against heat and cold, your air conditioner or heating system will be working harder to maintain a comfortable temperature. The result will be a rise in your energy bills.
