Installing a new roof can be a significant investment, so it is always a good idea to take steps that protect your roof and make it last as long as possible. But how long does the average shingle roof last?

Shingle Service Life

The lifespan of your roof will depend on the type of shingle that is installed. Here are the expected service life figures for the most common types of shingles:

• Three-tab shingles: Three-tab shingles are the most economical type of shingle, and they feature a typical lifespan of 15 to 20 years.
• Architectural shingles: Featuring a distinctive 3D profile, architectural shingles are thicker and more durable than the three-tab design, with an expected service life of 20 to 30 years.
• Premium shingles: High-end premium shingles can last anywhere from 25 to 40 years, or longer, depending on the manufacturer and product line.

What Affects Shingle Service Life?

Certain factors can significantly reduce how long your roof will last, including:

• UV radiation: Sun exposure, and specifically UV radiation, can degrade the tar and asphalt that bond the different layers of the shingle together, and this is a major concern in the Las Vegas area.
• Granule loss: The granules cover the surface of the shingle to protect it from UV radiation, and as this layer is lost due to the effects of wind, hail, heat, and foot traffic, damage from UV exposure will accelerate.
• Excessive heat: Sun exposure and high heat can soften the asphalt layer that retains the shingle granules, accelerating UV damage.
• Lack of attic ventilation: Heat is a major factor in the lifespan of a shingle, and if there is not adequate ventilation in the attic to cool the underside of the roof, the shingles will degrade much quicker.

How To Maximize the Service Life of Your Roof

To make your roof last as long as possible, choose the best shingles possible within your budget, and work with a professional roofing company to ensure they are installed correctly. Have your roof inspected every year or so to check for potential issues, and work with a qualified roofer to repair any problems right away, such as missing flashing, nail pops, or torn shingles. Finally, keep up with regular maintenance like cleaning the gutters to keep your roof protected, and install attic insulation to keep roof temperatures as low as possible.
