What do rain, snow, ice, sun and high winds have in common? They all contribute to the “wear and tear” of your roof and, eventually, the need for a new one. Among the telltale signs that your roof may need to be repaired or replaced are:
- Curled, buckled or cracked shingles. Curled shingles, for example, are vulnerable to high winds and ice damage. They’ll become rigid and can break easily.
- Broken or missing shingles. Broken or missing shingles weaken the roof’s ability to shed water.
- Granule loss from asphalt shingles. When shingles lose their protective granules, they begin to harden from heat and sun exposure, accelerating their aging process.
- Damaged flashing. Damaged flashing can allow water to penetrate to the roof deck beneath.
- Excessive mould or moss growth on shingles. This occurs most often in humid climates and typically appears as dark or greenish stains.
- Pools of water on a flat or low slope roof.
- Streaking along exterior your walls.
- Water stains or discolouration of interior ceilings or walls. Generally, this means that water has penetrated the wood roof deck, the roofing structure (trusses), attic insulation and has made its way through your drywall.
- Sagging ceilings.
- Outside light visible through your roof.
If you observe one or more of these things, contact a roofing contractor for a professional inspection. Depending on the degree of damage, the contractor may recommend some repairs or a full replacement. From there, you need to decide what’s best for you. Just remember that the cost of fixing or replacing a roof is usually less than repairing the damage an old roof can cause to your home.
And remember, repairing or installing a new roof isn’t typically a “do it yourself” project. It’s labour intensive and can be dangerous, too. Let a professional roofing contractor do it for you and do it right.
What the experts say…
According to industry experts, it’s a good idea to get have your roof professionally inspected every few years or following a major storm involving excessive winds.
