Roofs need to be repaired, or even replaced, immediately when they stop doing their job. The job, keeping out water, sounds simple, but there are many parts to the roof and many ways they can go wrong. Knowing the signs of when this breakdown is happening is vital to preventing more significant damage to the structure underneath. Let’s look at a few of the common signs that it’s time to replace your roof. 

  1. Time: Once 20 years have gone by, the clock has started ticking on your roof. Some roofs, like those using architectural shingles, will last longer than the 20 to 25-year life span, but mostly, your typical “three-tab shingle” roof is on its last legs when it reaches this milestone. 
  2. Layers: When an original layer of shingles has outlived its use, it is common practice for roofers to add a second layer of shingles to the first one. If there is damage to the decking underneath, this will not be possible because other repairs have to be made first. But when a second layer has been added, their lifespan is shorter than a single layer. The 20-year life span should be seen as the limit for two-layer roofs, not just the beginning of the end, like it is for single-layer roofs. 
  3. Moisture: Of course there will be moisture on the exterior of the roof at times, since its job is to direct it away from the home, but when there is moisture inside, your roof is clearly not functioning correctly. Inspect your attic area with a flashlight, and check for wet boards and insulation. These are a sign your roof needs immediate attention.
  4. Decking: The boards between the roof trusses and the shingles are called decking, and are typically made of plywood. While in the attic, also check that the decking boards are not sagging, wet, cracked or otherwise damaged. If you can see light between the boards, this is also a common sign of failure. 
  5. Valleys: The place in a roof where two sections meet is called a valley. These are meant to direct water towards the gutter. They are arguably the most sensitive part of a roof, because there is more room for error and more potential for damage if not operating properly. Check that all the shingles in the valley look like they are in place and undamaged. 
  6. Shingles: Other damaged shingles may not be quite as big of a deal to replace if it is an isolated issue from wind or a branch falling. If the shingles all look good but with one or two damaged ones, have them replaced by a professional roofer and ask him to check the health of the others while he is up there. Once many shingles begin to curl, warp and bend, it’s another sign your roof needs to be replaced.
  7. Granules: The shingles are manufactured with a sandpaper-like grit on top. These make the shingles more durable and resistant to the elements. Once the granules loosen and fall off, you will find bald spots, or entire smooth shingles. Another sign this is occurring is to find these granules in the gutter. 
  8. Flashing: In the past, they would use roof cement or tar to flash around chimneys, skylights, vents and other protrusions into the roof. This would protect these points from becoming weak points where water could enter. Now flashing is done with metal, so if you have old flashing made of tar or cement, it was likely done a while ago. Metal flashing can also go bad, so it’s good to have it checked as well.
