Asphalt Shingle Roofing in Charleston

Expected Lifespan of Asphalt Shingle Roofs

The lifespan of asphalt shingles can vary depending on the quality of the shingles and the type of roof they're installed on. On average, asphalt shingles will last about 20 years before needing to be replaced. However, this can be extended to 25 years if the shingles are installed on a roof with a layer of foam insulation.

Roofing materials are often affected by natural weather conditions, such as strong winds, heavy rain, and extreme temperatures. These conditions can shorten the lifespan of asphalt shingles, especially if they're installed on an older roof that lacks adequate insulation.

Ashley River Roofing can inspect your roof and let you know if it's time to replace your shingles. We'll also let you know if your roof is ready for a new layer of shingles or if it needs to be repaired and strengthened before it can support another layer of shingles.

Does My Asphalt Shingle Roof Need Repairs?

Regular inspection of your asphalt roof is crucial to identify any signs of damage or wear early on.

Here are some common signs that indicate your asphalt roof may need repair:

1. Missing or Damaged Shingles: Look for any missing, cracked, or curling shingles. These can expose the underlying layers of the roof and make it vulnerable to leaks.
2. Bald Spots on Shingles: If the granules on the shingles are worn away, leaving bald spots, it indicates that the shingles are aging and may need replacement.
3. Visible Roof Leaks: Water stains on the ceiling or walls inside your home are clear indicators of roof leaks. Address these issues promptly to prevent further damage.
4. Sagging Roof Deck: A sagging roof deck may suggest structural damage. If you notice a dip or sag in the roofline, it's essential to have it inspected by a professional.
5. Water Stains in the Attic: Inspect the attic for any signs of water stains, mold, or mildew. These can indicate leaks or poor ventilation.
6. Damaged Flashing: Check the flashing around chimneys, vents, and skylights for signs of damage or deterioration. Damaged flashing can allow water to seep into your home.
7. Gutter Issues: Clogged or damaged gutters can lead to water pooling on the roof, causing damage over time. Ensure that gutters are clean and in good condition.
8. Rotting or Mold Growth: Rotting or mold growth on the roof surface is a sign of excess moisture. This can compromise the structural integrity of the roof and should be addressed promptly.
9. Visible Nails: If you see nails poking through the shingles, it indicates poor installation or that the shingles are aging and may need replacement.
10. Daylight Through the Roof Boards: In the attic, check for any daylight coming through the roof boards. If light can penetrate, so can water. This may indicate gaps or damage in the roof structure.
11. Aging Roof: If your asphalt roof is approaching the end of its expected lifespan (typically 20-25 years), it's advisable to proactively assess its condition and consider replacement if necessary.

Regular inspections and timely repairs can extend the lifespan of your asphalt roof and help prevent more extensive and costly damage.

If you notice any of these signs, it's recommended to consult with a Charleston roofing professional to assess the extent of the damage and determine the appropriate course of action.
