Which Type of Shingles is Right for Your Commercial Roof?

Whether you’re constructing a new commercial building with a steep-slope roof, replacing the roof on an existing building, or beautifying a historic roof, it’s important to understand the differences in the types of shingles available to you.

Three-Tab Asphalt Shingles for Commercial Buildings

If you’re searching for a cost-effective commercial roofing solution for a steep-slope roof, asphalt shingles might be the solution for you. You can expect these roofs to last for up to 30 years (with proper installation and preventive maintenance). Plus, our shingle roof installation company offers a wide selection of available colors and grades.

Architectural Shingles for Commercial Structures

Compared to three-tab asphalt shingles, architectural shingles are sturdier and thicker, making them more durable and wind and water-resistant. These features do equate to a higher price point. However, these shingles often include lifetime warranties from our manufacturers. Architectural shingles need expert installation and regular maintenance to utilize these lifetime warranties fully.

Is Shingle Roofing Right for Your Commercial Building?

Not every commercial structure is a prime candidate for shingle roofing. Shingles are a good choice when the roof’s pitch is a minimum of 4:12 (that’s a vertical rise of 4 inches for every 12 inches of horizontal distance).

With various colors and textures, shingles can enhance your building’s aesthetic, helping to pull the entire look of your building together to match your vision. Some available colors include blue, red, brown, tan, white, green, gray, and many combinations of blended colors.

Asphalt shingles are also viable when your project’s budget is tight.

If your roof’s pitch is less than 3:12, shingles are not an ideal choice. Also, if you vent grease, fat, oil, or other flammables at roof level, shingles can ignite faster than other more fire-resistant roofing materials.

Shingle Roof Restoration in Ephrata, PA

GSM Roofing completed a full roof replacement on the historic Acorn Cottage — a 1928 Gordon-Van Tine kit home. The project involved removing the original roof and carefully installing new CertainTeed Landmark and GAF HD shingles to replicate the look of the original cedar while offering modern durability.

To address the home’s unique rounded eaves, our team built a mock-up, custom-fit the shingles, and added a j-channel for support. Berger Bros. gutter supports and hangers were also installed to maintain the home’s historic charm. The result preserved the cottage’s original aesthetic while delivering a long-lasting roofing solution.

Shingle Roof FAQ

How Long will a Commercial Shingle Roof Last?

While manufacturers provide lifespan estimates — typically ranging from 20 to 30 years for high-quality architectural shingles — the actual service life of a commercial shingle roof is not a fixed number. It is a dynamic outcome determined by the interplay of four critical, interconnected factors: the quality of the materials used, the excellence of the initial installation, the specific challenges of the local climate, and the rigor of the ongoing maintenance program.

How do Shingles Hold up against Heavy Rain, Wind, and Snow?

Modern asphalt shingle roofing systems are engineered to provide robust protection against a variety of weather conditions, but their performance depends heavily on the quality of the materials chosen and the precision of the installation.

Asphalt shingles are designed to handle tough weather. They shed heavy rain effectively, especially when installed with proper flashing around chimneys, vents, and valleys. High-quality architectural shingles also stand up well to strong winds — many are rated for gusts up to 130 mph — making them a durable choice for long-term protection.

In snowy areas, the bigger concerns are ice dams and freeze-thaw cycles, which can cause water to back up under shingles or weaken them over time. That’s why proper installation, insulation, and ventilation are key.

What Factors Determine the Cost of a New Commercial Shingle Roof?

A professional and transparent estimate from a reputable contractor will provide a detailed breakdown of the key factors, moving beyond a simple price-per-square-foot to give a complete and accurate picture of the project investment. These key variables include:

Roof size and complexity
Material selection
Condition of the existing roof and decking
Accessibility and site logistics
Permits, codes, and warranty level

Can a Shingle Roof Help Lower My Building’s Energy Costs?

Yes, a modern shingle roofing system can make a significant and measurable contribution to reducing a commercial building’s energy consumption and lowering utility costs. However, achieving these savings requires a holistic, system-based approach. The benefits are derived from the combined performance of three key components

Reflective shingle technology
Proper attic or plenum ventilation
Adequate insulation

I do not check the work. But I can say that the two men answered my question with courtesy. They assured me that the roof is in good order. And your company responded to the work order on short notice as coordination with plumber’s installation was key. My association with your company has always been more than satisfactory.
