Architectural Roofing Shingles: How to Protect Your Home from Algae

If you're tired of spending the beginning of each fall season cleaning algae off your roof, exchange your current 3-tab shingles for architectural roofing shingles. Architectural roofing shingles come with a number of features that protect your home from algae growth in the summer. Although algae doesn't cause structural damage to your roof, siding or attic, it makes your home appear unattractive and neglected, which can reduce the value of your property. Instead of using harsh chemicals to remove the black streaks of algae from your roofing shingles, install architectural shingles instead. Here's how algae forms on your roof and how architectural shingles improve the appearance of your home.

How Are Architectural Shingles Different from 3-Tab Shingles?

Although 3-tab roofing shingles cost less than architectural shingles, they don't protect your roof from algae growth due to a number of things, including their density. Three-tab shingles are lightweight and thin, which allow water and moisture to penetrate their surfaces easily. Algae needs a damp surface to grow and thrive. 

Manufacturers design architectural roofing shingles with thicker or denser textures. Rainwater and moisture can't penetrate the thickness but will bead or roll off the shingles instead. Without a wet surface to attach to and grow, the spores of algae die once they land on the surfaces of architectural shingles.

Architectural shingles also come with several, heavy layers of asphalt or fiberglass material that stick firmly to the roof's surface. The layers keep heat from building up beneath your roof's underlayment and inside your attic. Three-tab shingles can trap moisture and heat beneath them, which gradually damages the roof's underlayment and wooden frame. If your 3-tab roofing shingles have a history of developing blisters on their surfaces, switching to architectural roofing shingles eliminates this problem. 

In addition, architectural shingles come in numerous styles, colors and sizes you can use to create a unique look for your home. For instance, if you have turrets or other high-standing structures on your roof, you can use architectural shingles to create a dramatic look that makes your home stand out in the neighborhood. Roofers overlap lightly-colored shingles with darkly-colored shingles to form the look you want to create for your home

Can You Add Other Features to Architectural Shingles to Prevent Algae Growth on Your Roof?

If you want to protect your home from algae even further, have your roofing contractors coat your architectural shingles with a algae prohibitor. Algae prohibitors, such as zinc granules, are treatments that don't fade, wear down or deteriorate soft and hard materials after application. Instead, the treatments form a strong barrier on the surfaces of your architectural shingles.

Although zinc granules look like tiny grains of sand, they blend in easily with the white and gray specks on the shingles' surfaces. If algae spores land on the treated shingles, they die or wither away. Additionally, roofers can seal the granules with a waterproof material that keep them in place during heavy rainstorms, snowstorms and winds.

After your roofers replace your 3-tab roof with architectural shingles, minimize the growth of algae on your property by having your trees professionally trimmed back away from your home. Along with moisture and water, algae requires shady areas like those under overhanging branches of large trees to grow.

However, don't worry about the sun's rays damaging your new roofing shingles or home. The thick surfaces of architectural shingles protect your home from heat and sun damage by forming a shield over your attic and other interior structures. Instead of penetrating your home's foundation and building up, the sun's heat stays on the outside of the shingles to keep your home cool and comfortable.
