Discover How Long a Shingle Roof Should Last
Three primary types of asphalt shingles are 3-tab, dimensional, and premium.
Shingle roofs can last between 20 to 35 years. However, many factors influence a roof's lifespan, including age, current condition, material, design, and regional weather conditions. Since it's an expensive investment, caring for the roof is critical.
Please keep reading to find out how long a shingle roof should last.
Type of shingles
Three primary types of asphalt shingles are 3-tab, dimensional, and premium. All three types should last for 80% of the expected lifespan if properly installed. A 3-tab shingle roof can last between 20 and 22 years, while a dimensional roof lasts from around 25 to 28 years, depending on installation and ventilation.
A 3-tab shingle roof is a good option for temperate areas and a household on a budget. A strip roof contains a fiberglass base and is easily installed, portable, and cheap.
As the name suggests, a thin layer of asphalt on a dimensional roof gives them a three-dimensional look. Since this roof is constructed with more than one layer, its durability surpasses a 3-tab roof but costs more.
Premium shingle roofs last from 20 to 30 years on average. This type seems more luxurious in appearance, but the cost is not much higher than dimensional shingle roofs. The premium shingle roof is a good choice for severe weather, including hurricanes and tornadoes.
The weather conditions
Both warm and severe weather impacts the roof and its durability. Warm weather can produce cracks on shingle roofs, while extreme weather causes granular loss. Harsh weather conditions are one of the reasons for premature failure of the roof.
Quality installations
One must correctly install quality roofing materials. Otherwise, the roof's lifespan will be shortened. Householders should always consult with a professional firm when considering a shingle roof.
Attic ventilation
A well-ventilated attic is essential for the lifespan of the roof. Good air circulation is needed to avoid moisture and heat damaging the roof. When left unchecked, the attic gets too warm and damages the roof. Keeping the temperature cool in the attic saves money on utility bills too. Moisture in the attic may lead to a leak, yet another problem people with asphalt roofs must worry about in cold weather.
Accumulations on the roof
Moss accumulation typically means the roof has remained wet for extended periods. Also, moss shouldn't accumulate on the roof or gutter lines, valleys, and downspouts. These problems lead to a leak and reduce the average lifespan of the shingles.
Look for the signs
Many aspects affect the lifespan of a shingled rooftop. Significant damage may arise from harsh storms or too much heat. Call a professional roof specialist if you notice that the roof requires repairs.
