Six Signs Your Roof Needs To Be Replaced

Posted on: 18 May 2015

Roofs have a limited lifespan, and will wear away over time due to weather exposure and general wear and tear. A roof that has reached the end of its lifespan can quickly cause other problems in your house by allowing water to seep inside, which can lead to water damage and mold growth. Knowing the warning signs of a roof that needs to be replaced can help avoid such problems from developing.

Exterior Signs

Damaged Shingles: Looking at missing or damaged shingles can tell you whether or not you need to replace your roof. Missing shingles can usually be attributed to high winds and heavy precipitation, but shingles that have begun to curl at the edges have reached the end of their lifespan and should be replaced.

Rot: Any signs of significant mold or rot growth (usually discoloration, but sometimes actual plant growth can be observed, or soft and sagging spots in the roof) means that your roof should be replaced. However, if there is rot and mold growth on your roof, it has probably already spread into your home, which will require removal and cleaning.

Gutters: Check your gutters after a period of heavy rainfall. If there are lots of small black granules collected in there, your shingles will probably have to be replaced, as they have become extremely worn down and thus less able to resist weather exposure.

Interior Signs

Light: If you can see sunlight when inspecting your roof in the attic, there is a serious problem, and your roof is not providing adequate coverage. Light usually means that water can get in as well.

Water Damage: Any form of water damage in your attic means that your roof has reached the end of its lifespan. Look for any signs of mold and mildew growth, or discoloration. Discoloration does not necessarily mean mold – water runoff from shingles will be tinted black, and leave long trails of black stains on your walls and floor if it manages to get inside.

Sagging: If the roof deck (which is the base to your roof on which shingles and other roofing materials are applied) is visibly sagging downwards at any point in your attic, your roof should be replaced immediately. Sagging means that water can flow underneath the shingle layer and build up on top of your roof deck, which at one point will give way and release a large amount of water into your home.
