Detail-Oriented and Customized Commercial Roofing
The most important thing regarding commercial roofing is proper installation. The flashing. The details. This work must be performed by a master roofer for proper installation, otherwise, your roof investment won’t perform as long as promised. Maryland business owners love working with G and Bros for that very reason.

Insurance, Permits, and Code Compliance
Commercial roofs aren’t just about shingles. They’re about meeting Maryland and Delaware building codes, satisfying your building’s insurance carrier, and passing inspection before the certificate of occupancy. We pull every permit ourselves. We coordinate directly with your insurance adjuster when storm damage is involved. We handle the paperwork so you can keep running your business.
Our team is fully licensed in Maryland and Delaware. We carry general liability and workers’ comp on every job. We work with all major commercial insurance carriers including Cincinnati, Travelers, Liberty Mutual, and The Hartford. If your insurance company needs documentation, drone photos, or written reports, we have them ready before they ask.
G and Bros has been a family-owned Eastern Shore roofing company since 2012. Our founder Guillermo Molina-Reyes brings 25+ years of hands-on Maryland roofing experience to every estimate, and every member of our sales team has worked on a roof, not just sold one. When you hire us, you get a crew that has been doing this together for years.
Energy-Efficient Commercial Roofing Options
A reflective commercial roof can drop your building’s cooling costs 10-30% per year. We install ENERGY STAR rated TPO and PVC membranes that meet Cool Roof Rating Council (CRRC) standards. For older flat roofs, we apply silicone or acrylic roof coatings that extend roof life by 10-15 years and qualify for ENERGY STAR credits without a full tear-off. Our team helps you weigh the upfront cost against your monthly energy savings before you commit.
If you’re chasing LEED credits, applying for a federal energy efficiency tax deduction (Section 179D), or trying to lower your building’s operational footprint, we’ll spec the right system for your goals and your budget.
Different buildings need different roofs. Here’s what we install and repair across Maryland’s Eastern Shore, and where each one fits.
| Material | Lifespan | Best Fit |
|---|---|---|
| TPO | 20-30 yrs | The most common modern membrane. Single-ply white sheet that reflects sunlight, ENERGY STAR rated, can drop cooling bills 10 to 30 percent. Warehouses, offices, big-box retail. |
| EPDM (Rubber) | 20-25 yrs | The original commercial membrane, since the 1960s. Black rubber sheet that handles big temperature swings. Lowest upfront cost. Older industrial buildings and storage facilities. |
| PVC | 20-30 yrs | Resists grease, chemicals, and fire better than TPO or EPDM. Class A fire rating. Restaurants with grease-vent exhaust, hospitals, chemical-exposure environments. |
| Modified Bitumen | 20 yrs | Multi-layer asphalt system, torch-applied or self-adhered. Extra puncture resistance for HVAC foot traffic. Solid retrofit option when you don’t want a full tear-off. |
| Standing Seam Metal | 40-70 yrs | The longest-lasting commercial roof we install. Raised seams shed water, snow, and high winds. Critical on the Eastern Shore during hurricane season. Agricultural buildings, churches, modern offices. |
| Silicone Coatings | +10-15 yrs | Restoration over an existing membrane with 5 or more good years left. Seals seams, fills punctures, reflects heat. No tear-off, no tenant disruption, fraction of replacement cost. Best for property managers deferring a capital expense. |
| Architectural Shingles | 30-50 yrs | For pitched commercial roofs that aren’t flat. GAF Timberline HDZ with lifetime warranty. Churches, schools, historic buildings where the roof is visible from the ground. |

Frequently Asked Questions
What kinds of commercial properties can you serve?
We can install roofs on any commercial property, including offices, churches, retail stores, restaurants, warehouses, schools, and more!
What commercial roofing materials can you install?
We repair and replace TPO, PVC, EDPM, and metal roofing materials.
What is TPO roofing?
TPO stands for thermoplastic polyolefin, and it’s a single-ply white roofing membrane used on low-slope roofs. Since TPO is white in color, it reflects heat instead of absorbing it, which keeps the building cooler.

For qualifying residential roof replacements, we can provide enhanced GAF warranties, including the Silver Pledge Limited Warranty, as a GAF Certified Plus Contractor.
