General Contractor, expert advise, ProfessionalQuestion:  I was told it would be better to replace my roof because of its age instead of repairing it.  Its only 15 years old isn’t that too early to replace a roof?  MC

Answer:  This really depends on the actual condition of the existing roof and the type of roof materials.   Its always good to get more than one expert to look at your roof.

In the mean time being educated on your roof may help you.

Here is some data I got from a local roofing company:

Roofing Material

  1. Asphalt Shingles, 3-tab – 15 to 20 years
  2. Asphalt Shingles, Architectural – 24 to 30 years
  3. Galvalume (metal) – 30 to 45 years
  4. Concrete Tile – 35 to 50 years
  5. Built-Up or Modified Bitumen – 10 to 16 years
  6. EPDM (rubber) – 10 to 16 years (Ethylene Propylene Diene Monomer)

Roofs: Slate, copper and tile roofs can last more than 50 years. Homeowners with wood shake roofs should expect them to last about 30 years, while fiber cement shingles last about 25 years.

But average lifespan estimates are based on “average” conditions. Many factors contribute to a longer or shorter life of the roof; so a particular roof’s life can vary—sometimes significantly—from the average. Here’s a list of conditions that affect roof longevity:

  • Color of roof – A dark roof absorbs more heat, which shortens the lifespan.
  1. Angle of roof slope – Higher pitch roofs tend to last longer.
  2. Orientation of roof surface – A roof slope facing south will get more sunlight, and have a shorter life.

Hope that helps!                                            Dave Silva, GC
