When we say we protect you from the elements, including time, we mean it.
Commercial roofing isn’t one-size-fits-all. Different buildings need different solutions. Our expertise spans across all major commercial roofing systems, so you can have peace of mind knowing that our recommendations come from years of experience and care for your success.
PVC (polyvinyl chloride) roofing offers exceptional durability and weather resistance. This single-ply membrane system resists chemicals, fire, and punctures better than many alternatives. The heat-welded seams create watertight bonds that outlast adhesive or mechanical attachments.
PVC roofs reflect sunlight, helping reduce cooling costs during warm months. They require minimal maintenance and typically last 20-30 years with proper care. We install Duralast PVC systems backed by comprehensive warranties.
TPO (thermoplastic polyolefin) roofing combines affordability with performance. This popular single-ply membrane is lightweight, energy-efficient, and relatively easy to install. TPO’s reflective white surface helps lower energy costs by keeping buildings cooler.
We install TPO systems with heat-welded seams for maximum water resistance. This roofing type works well for various commercial applications, from small offices to large warehouses. Modern TPO formulations provide excellent UV resistance and flexibility.
EPDM (ethylene propylene diene monomer) rubber roofing has protected commercial buildings for decades. This durable, flexible membrane handles temperature extremes without cracking or becoming brittle. EPDM’s proven track record makes it a reliable choice for flat and low-slope roofs.
Available in black or white, EPDM can be mechanically attached, fully adhered, or ballasted depending on your building’s needs. It resists ozone and UV radiation naturally. Many EPDM roofs last 20-25 years or longer with proper maintenance.
BUR (Built-Up Roofing) is one of the most tried and trusted commercial roofing systems. Built-up roofing is made of multiple layers of bitumen and reinforced fabrics to create a thick, durable membrane. This redundancy means that even if one layer fails, others continue to protect your building.
BUR systems handle heavy foot traffic well, making them ideal for roofs with regular maintenance access. We apply reflective coatings to improve energy efficiency. These roofs typically last 20-30 years and can often be restored rather than replaced.
Metal roofing delivers unmatched longevity and strength. Steel, aluminum, and other metal systems can last 40-70 years with minimal maintenance. They resist fire, rot, insects, and extreme weather conditions that damage other roofing types.
Modern metal roofs come in various profiles and colors to match your building’s aesthetic. They’re lightweight, reducing structural load, and highly recyclable at end-of-life. Metal’s durability makes it a smart long-term investment for commercial properties.
Silicone roof coatings extend the life of existing roofing systems without complete replacement. These liquid-applied coatings create a protective barrier that seals minor leaks, reflects UV rays, and resists ponding water. We’re factory-certified installers of Gaco silicone roof coatings.
Coating application is cost-effective compared to tear-off and replacement. It reduces landfill waste and disruption to your operations.
Properly applied coatings can add 10-20 years to your roof’s lifespan while improving energy efficiency.
Curious which system suits your building? Let’s discuss your options.
Project timelines vary based on roof size, system type, and complexity. Small commercial roofs might take 3-5 days, while larger buildings can require 2-3 weeks. We provide detailed timelines during the planning phase.
Yes, we work with property owners and insurance companies to document damage and process claims. Our detailed reports and documentation help streamline the claims process.
Lifespans vary by material. EPDM and TPO typically last 20-25 years, PVC lasts 20-30 years, BUR lasts 20-30 years, and metal roofing can last 40-70 years. Proper maintenance extends these lifespans.
Absolutely. We coordinate scheduling to minimize disruption to your operations. Many projects can be completed during evenings, weekends, or slow business periods.
We recommend annual inspections at a minimum. After severe storms or if you notice any issues, schedule an inspection immediately. Proactive inspections prevent costly emergency repairs.
We offer manufacturer warranties extending up to 50 years on materials, plus workmanship warranties on our installation. Specific coverage depends on the roofing system and manufacturer.
We believe in straightforward pricing that you can actually understand.
When we provide a quote, that’s the price you pay—period.
