Due to their relatively low cost, 20-year average lifespan, energy-efficiency, and recyclability, asphalt shingles are a top roofing solution for homeowners. Despite these many benefits, some consumers are reluctant to invest in the solution because of myths surrounding the product. If you’re unsure how to approach an upcoming roof installation or replacement project, here’s what you should know. 

5 Common Misconceptions About Asphalt Roof Shingles

1. They Are Weak

In the past, asphalt shingles featured design flaws that made them more prone to blistering, curling, and cracking. However, modern enhancements now allow the material to satisfy its expected service life—such as reinforced fiberglass mats and self-sealing adhesive tabs.

Since product quality can vary depending on the manufacturer, it’s important to work with your roofing contractor to avoid low-grade materials—such as those that use stone fillers.

2. There Shouldn’t Be Loose Granules After Installation  

Over time, shingles gradually lose their top layer of crushed stone granules, which, in turn, leaves the roof susceptible to damage. For this reason, many homeowners get concerned when they see a high amount of granules after the initial roof installation.

This granule loss, however, is a normal result of the installation process and shouldn’t raise concerns. Eventually, your new roof’s granule loss will diminish. 

3. Nail Gun Installation Is Problematic

Roofing contractors will either hand-nail shingles to the structure or use a nail gun. Each of these methods is effective, so long as the roofer makes sure the right amount of nails are placed in the right position.

4. Darker Colors Boost Energy Costs

While it’s true that lighter colors help reflect sunlight, darker asphalt shingles won’t necessarily harm your roof’s energy efficiency. If you have high cooling bills in the summer, the problem may be linked to poor insulation or ventilation.

The color of the roof typically only makes a significant difference in climates that receive warm sun year-round. The dark color helps the home absorb and retain heat in winter, off-setting slightly higher costs in summer. 

5. Materials Contain Asbestos

Some asphalt shingle brands once contained asbestos—a known carcinogenic. Thanks to strict regulations introduced in the 1980s, manufacturers no longer use this potentially harmful material to produce shingles.
