Find the Best Roof System for Your Building
Reinforced Fabric Membrane
Key Benefits
Embedded fabric stops tears from spreading while staying flexible through Pennsylvania’s temperature swings without cracking.
Best For
Buildings that need regular roof access for equipment maintenance and properties with heavy rooftop mechanicals.
Metal Roof Restoration
Key Benefits
Coating existing metal costs far less than replacement. It extends roof life and improves energy performance by sealing fasteners.
Best For
Older industrial buildings with surface corrosion but solid structure, common in pre-1980 commercial properties.
PVC Commercial Roofing
Key Benefits
Heat-welded seams create permanently bonded joints stronger than the membrane itself, resisting grease, chemicals, and foot traffic. The white surface reflects up to 80% of UV rays helping cut down cooling costs.
Best For
Restaurant kitchens along West Liberty Avenue, medical facilities where leaks create liability issues, and manufacturing plants where downtime is expensive.
TPO Roofing Systems
Key Benefits
Welded seams create waterproof barriers, while the reflective finish helps manage building temperatures and reduces cooling loads at an accessible price point.
Best For
Retail centers, office complexes, and mixed-use developments that need reliable protection on a budget.
Spray Polyurethane Foam
Key Benefits
Foam expands to fill every gap and adds significant insulation in a single application. This seamless system eliminates weak points and reduces both heating and cooling expenses.
Best For
Properties with rooftop HVAC equipment, warehouses focused on energy savings, and older buildings with complicated roof shapes.
Premium Roofing Materials for Commercial Applications
Commercial Grade TPO Membrane
Heat-welded seams create a permanent waterproof seal, while the reflective white surface helps resist ponding water and reduce heat absorption. The result is long-lasting performance with improved energy efficiency.
Elastomeric Metal Roof Coatings
Designed specifically for metal roofs, these flexible coatings seal fasteners, prevent rust, and expand and contract with temperature changes to reduce cracking and extend roof life.
Fabric-Reinforced Membrane Sheets
Embedded polyester fabric strengthens the membrane to prevent punctures from spreading. The material remains flexible in freezing temperatures, helping your roof withstand heavy stress and harsh weather.
Closed-Cell Polyurethane Foam
Spray-applied foam expands into gaps and irregular surfaces to create airtight coverage and exceptional insulation. This seamless barrier improves energy efficiency and reduces heating costs during cold Pennsylvania winters.
Commercial PVC Membrane
Heavy-duty sheets are welded on-site to form seams stronger than the membrane itself. PVC resists chemicals, extreme temperatures, and heat absorption, making it ideal for demanding commercial environments.
