Several ways to identify whether your roof requires replacement:
- Age: Roofs have a lifespan, typically 20 to 30 years, but it can vary depending on the material. If your roof is approaching or has exceeded its expected lifespan, it’s a sign that you may check it for replacement or repair.
- Missing or damaged tiles: Look for any roof tiles that are cracked, curled, blistered, or missing. Damaged roof tiles expose the underlying structure to water and can lead to leaks.
- Leaks and water damage: If you notice water stains on your ceiling or walls, it’s a clear sign of a roof problem.
- Granule loss: Often, roof tiles shed their granules as they age, causing a sandy residue in your gutters. This can reduce the effectiveness of the tiles and indicate the need for replacement or repair.
- Sagging or uneven roof: An irregular roofline or sagging sections suggest immediate structural issues. It’s best to call a roofing contractor and get your roof checked.
- Algae or moss growth: Algae, moss, or mould pose severe risks to your health, whether inside or outside your house. If you can see such things, it indicates a moisture problem that needs addressing.
- Damaged flashing: Cracked or deteriorating flashing around roof penetrations like chimneys and vents can lead to leaks. Ensure the flashing is in good condition.
- Excessive energy bills: If your energy bills have unexpectedly increased, it could be due to deteriorating felt covering and/or lack of insulation.
