New Commercial Roofing Construction Backed by Old-Fashioned Workmanship

New buildings need great roofs—we all know that. But when it comes to new construction, there are so many variables to juggle. Commercial roofing construction for brand-new buildings can be an afterthought, even though it’s a critical element that you shouldn’t push to the bottom of the priority pile.

If you’re an owner, project manager, or general contractor, we will work with you to choose the right new commercial roofing system, so you have one less thing to worry about when it comes to your business.

As you plan for commercial roofing construction, what’s on your must-have list? Do you want energy efficiency? The best guarantee in the industry? Proven long life? A unique finish to your distinctive structure?

These are just the opening questions in the quest for the perfect roof for your new building. And with so many options, the possibilities are virtually limitless.

With the help of the commercial roofing construction specialists at GSM Roofing, you will have the following options to choose from:

Built-Up Roofing Systems

Built-Up Roofing Systems are some of the most durable roofing solutions available, and we’ve been using this technology on low-slope roofs since 1946. Application processes vary and include hot-mopped or cold-applied, gravel-surfaced or smooth-coated, and traditional or modified bitumen.

We offer the highest-quality shingles for your dollar with our manufacturer affiliations and never overlook a single detail when expertly applying them to your new roof.

Slate Roofs

Slate Roofs are a specialty that earned us the privilege of contributing to the updated slate installation manual for the National Slate Association. This expertise is essential when installing a slate roof—particularly when you want a distinctive historical look for your new construction.

Tile Roofs

Tile Roofs can take on several different looks, thanks to various available tile shapes, colors, and sizes. Make your new building stand out with clay, barrel-shaped, or cement tiles that offer wind and fire resistance, durability, longevity, long-term economy, and more.

Metal Roofs

Metal Roofs installed by our roofing experts can be of the custom or pre-manufactured variety. Custom new roof construction can include options like domes, standing-seam copper, and zinc panels, while pre-manufactured roofs offer benefits like affordability and many styles and color options.

Cedar Roofs

Cedar Roofs add character to any building. We have decades of experience installing cedar shake shingles over traditional lathe and plywood with a cedar breather. With all of cedar’s intricacies, it will last more than 50 years if properly installed with metal flashings, valleys, and ridge caps.

Roof Installation at F&M College

GSM Roofing successfully completed a complex new construction project at Franklin & Marshall College’s Multi-Purpose Stadium in Lancaster, PA.

The work included multiple advanced waterproofing systems: Grace Preprufe 300R for the elevator pit, Grace Bituthene 3000-LT for below-grade walls, and American Hydrotech MM6125 hot melt waterproofing for structural slabs and plaza roofs, complete with insulation, EFVM testing, and concrete topping.

Our team also installed a striking Virginia slate roof featuring a random 4-color pattern, copper gutters, and custom fascia and soffits, along with a Firestone (Elevate) EPDM system on the shed dormer roof — ensuring durability, performance, and architectural appeal across the entire facility.
