Asphalt Lifespan … What to Expect From Your Roof
There are several factors involved in estimating the lifespan of an asphalt roof. First is the type of shingles you choose, second has to do with the climate and third is maintenance. Read on to learn about some of the determining factors for your roof’s health.
Here is information on asphalt types, the impacts of weather, and extending your roof’s life.
WHICH TYPE OF SHINGLES DO YOU HAVE?
There are three main types of shingles and their properties impact their longevity.
1. Common three-tab shingles have a lifespan of 20-25 years. This type of roofing material is affordable, durable and accessible. They are a popular choice for sloped roofs.
2. Architectural shingles are made of fiberglass with a layer of asphalt, giving them a dimensional appearance. They are durable, with a typical warranty for 30 years.
3. Premium shingles are typically found on high-end homes. They have a higher profile and are reliable for 20-30 years.
DO YOU HAVE HARSH CLIMATE CHANGES?
Asphalt shingle deterioration is more rapid in areas with severe weather conditions. In extremely cold climates with snow and wind, the granules of asphalt roofs take a beating. In areas with harsh sunlight, roof shingles also might not last as long. Thermal shock and other heat-related problems create cracks and ultimately create damage to your shingles.
DILIGENT MAINTENANCE EXTENDS ROOF LIFE
Regular maintenance – we recommend Spring and Fall – is the best way to guarantee a longer life for your shingles. Maintenance includes inspecting your roof for missing and damaged shingles, promptly repairing leaks and cleaning debris off your roof. Periodic cleaning also prevents the growth of moss, which deteriorates your shingles.
Applying roof coatings or sealants, as recommended by your roofing professional, will add an extra layer of protection from UV and weathering. Homeowners who pay close attention to their roofs … and gutters … will enhance the performance of their roof’s asphalt shingles.
Another thing to monitor is attic ventilation. Poor ventilation can contribute to moisture buildup, leading to the growth of mold, mildew and wood rot. These are serious considerations, affecting the structural integrity of your roof. Effective attic ventilation helps regulate temperature and moisture, reducing thermal expansion, and preserves the resiliency and life of your shingles.
When to replace shingles
- Age: Consider replacing your shingles when they are between 20 and 30 years old.
- Water damage: Persistent leaks and/or water stains in your attic or ceilings are signs that your roof requires immediate attention.
- Buckling: Curling or buckling shingles are exposed to wind and water damage. These are obvious signals that they need replacing.
- Granule loss: Excess sand-like grains accumulating in your gutters or downspouts indicates shingle deterioration.
- Missing shingles: A few missing shingles can compromise the integrity of your roof. Replacement of missing shingles is urgent.
