Commercial Roofing Systems We Install
Commercial properties have very different roofing requirements than residential homes. Big Fish Roofing installs all major systems and recommends the best option for your building’s design, budget, and performance goals. TPO — highly reflective, reducing cooling costs, with heat-welded seams that create a watertight bond. Ideal for flat and low-slope roofs on retail, warehouse, and office buildings. EPDM, a durable synthetic rubber membrane that resists extreme temperatures, UV, and weathering. One of the most cost-effective options for large flat-roof buildings. Modified Bitumen — multi-layer systems with excellent waterproofing and foot-traffic resistance, ideal for buildings with rooftop equipment. Built-Up Roofing (BUR), alternating layers of bitumen and reinforcing fabric for redundant waterproofing and proven durability. Metal, the longest service life (40-60+ years), superior wind resistance, and minimal maintenance. PVC, the premium choice for buildings exposed to chemicals or grease, popular for restaurants and food processing facilities.

Commercial Roof Maintenance & Repair
Regular inspections and small repairs are the cheapest way to extend a commercial roof’s life. Big Fish Roofing offers preventive maintenance tailored to your building’s roofing system, age, and exposure conditions. Common issues we address include ponding water that accelerates membrane deterioration and adds structural load, membrane punctures from foot traffic or equipment installations that compromise the waterproof barrier, flashing failures at edges and penetrations caused by thermal expansion, and clogged drains and scuppers that prevent proper water flow. Emergency repair service is available when storm damage, sudden leaks, or equipment-related punctures threaten your building. A well-maintained commercial roof can last years beyond its expected service life, saving tens of thousands in premature replacement costs.
How to Choose a Commercial Roofing Contractor
Selecting the right commercial roofing contractor directly impacts the performance and longevity of your roofing system. Not every roofer is equipped for commercial work. Verify commercial experience — ask how many commercial projects the contractor has completed and request references from similar buildings. Confirm licensing and insurance — look for general liability appropriate for commercial work and workers’ compensation for all employees. Look for manufacturer certifications — certifications from manufacturers like GAF demonstrate strict standards for training and installation quality, and qualify you for manufacturer-backed warranties. Evaluate warranty options, the best commercial roofers offer both a workmanship warranty and a manufacturer’s material warranty. Check references on projects similar to yours in size and system type. Do not choose the lowest bidder — in commercial roofing, the lowest price often means thinner membrane, fewer fasteners, or inexperienced labor. A qualified contractor with proper materials saves you significantly over the life of the roof.

What Property Owners Say About Big Fish Roofing
Our reputation is built on delivering consistent results for property owners across Western Pennsylvania. Here is what a few of our satisfied clients have to say about working with the Big Fish Roofing team.
The estimator that looked at my roof started with the company as a laborer, worked his way up to boss and then as sales/estimator. He inspected my roof. We sat down and talked. He told me what he found, which sounded accurate. He also explained that they might need to replace some sheeting. They would provide 2 sheet of plywood and any more would be on me. Gutter guards and a larger fan was included in the quote. The quote also had a 50 year transferable warranty.. He had a printer in his vehicle and printed out the quote before he left. A few other contractors were contacted. They would provide a quote and usually, well. . .if you want a warranty you might need to pay for X.
My life got complicated. Last month Marc was contacted and my project was put on the schedule. They showed up today at about 8:00 a.m. After seeing all the roofing in the neighborhood, my surprise at a 1 day promise of completion raised some doubt. Before the project began, all the shrubs were covered with heavy tarps and anything in the way was was moved. They stripped the old roof, flashing, pipe buckets and started putting back about 9:30 a.m. First was a waterproof layer, then a layer of grid and then the shingles. All the flashing was replaced, all the pipe boots, a new ventilation fan was installed. the gutter guards were installed. They used a big magnet to pick up the nails. When they left everything was cleaned and put back.
THEY WERE DONE AND IN THEIR VEHICLES BY 1:30 p.m I have NEVER seen a group that worked so well together. I got a discount for paying the full price. Guess what! NO ADD ON. The same as the original quote.
In today’s world it is truly fantastic to have a contractor like Big Fish. Call them. . .you won’t be disappointed
Big Fish was fantastic from start to finish! After receiving quotes from a few different roofers, their presentation of their services and quoting process was very helpful and impressive! They were more than willing to help work within our budget. Communication with their office and project managers was always friendly, prompt and efficient. On the day of the install, everything went smoothly and seemlessly. The project manager was on site overseeing the job the entire time. They said they’d be done in a day, and they worked so quickly and with such precision, it took just under a day’s time! I’d definitely recommend Big Fish to any and every one who is looking for a roofer!
Our new roof is beautiful! We are so pleased. The help and guidance provided by project manager Marc Kania made all the difference from choosing the right color shingles to choosing the right package. Thank you very much. We will be using Big Fish for our siding in the future!
Frequently Asked Questions
What types of commercial roofing systems does Big Fish install?
Big Fish Roofing installs all major commercial roofing systems including TPO, EPDM, modified bitumen, built-up roofing (BUR), standing seam metal, and PVC membrane. Each system has specific performance characteristics suited to different building types, budgets, and environmental conditions. Our team evaluates your property and recommends the system that provides the best long-term value for your situation.
How long does a commercial roof last?
The lifespan of a commercial roof depends on the system type, installation quality, and maintenance. TPO and EPDM membranes typically last 20 to 30 years. Modified bitumen and built-up roofing systems last 20 to 25 years. Metal roofing can last 40 to 60 years or more. PVC membranes generally last 20 to 30 years. Regular preventive maintenance can extend the life of any commercial roofing system by several years.
How much does a commercial roof replacement cost?
Commercial roof replacement costs vary based on the size of the roof, the system selected, the condition of the existing roof deck, and accessibility. Most commercial projects range from $5 to $12 per square foot installed, though complex projects or premium systems can cost more. Big Fish Roofing provides free, detailed estimates for commercial projects. Call 724-954-3827 to schedule an inspection.
What is the difference between TPO and EPDM roofing?
TPO is a white, reflective thermoplastic membrane with heat-welded seams that is highly energy efficient and resistant to chemicals and punctures. EPDM is a black synthetic rubber membrane that is extremely durable, performs well in extreme temperatures, and is typically more affordable. TPO is often preferred in warmer climates or where energy savings are a priority, while EPDM is a strong choice for large flat-roof buildings where cost-effectiveness and proven long-term performance are the main considerations.
How often should a commercial roof be inspected?
Commercial roofs should be inspected at least twice per year, typically in spring and fall, and after any major storm event. Regular inspections catch small issues like membrane punctures, flashing separations, and clogged drains before they lead to costly leaks or structural damage. Big Fish Roofing offers preventive maintenance that include scheduled inspections and priority repair service.
What are the signs that a commercial roof needs to be replaced?
Common signs include persistent or recurring leaks that cannot be permanently repaired, widespread membrane blistering or cracking, significant ponding water that does not drain within 48 hours, visible sagging in the roof deck, moisture or mold in the building interior, rising energy costs due to lost insulation value, and the roof approaching or exceeding its expected service life. If you notice any of these issues, schedule a professional inspection to assess whether repair or replacement is the better option.
What is a roof coating and when is it appropriate?
A roof coating is a liquid-applied membrane that is rolled or sprayed onto an existing commercial roof to extend its service life. Coatings can add 10 to 15 years of protection, improve energy efficiency through reflectivity, and seal minor cracks and seams. Coatings work best on roofs that are structurally sound with no significant moisture intrusion. They are not a substitute for replacement on a roof that has reached the end of its useful life.
Can a commercial roof be made more energy efficient?
Yes. Reflective roofing membranes like white TPO and PVC significantly reduce heat absorption and lower cooling costs. Additional insulation can be added during a roof replacement to improve thermal performance. Roof coatings applied to existing dark-colored roofs add reflectivity without a full replacement. Proper drainage and ventilation also contribute to energy efficiency by preventing moisture buildup that degrades insulation.
Does Big Fish Roofing handle emergency commercial roof repairs?
Yes. Big Fish Roofing provides emergency repair service for commercial properties. When a sudden leak, storm damage, or equipment-related puncture threatens your building, our crew responds quickly to secure the roof, prevent further interior damage, and perform temporary or permanent repairs. Call 724-954-3827 for emergency service.
Does Big Fish handle insurance claims for commercial roof damage?
Yes. Insurance claims assistance is a core service for our commercial clients. When storm damage occurs, Big Fish documents all damage with detailed photos and measurements, meets with your insurance adjuster on-site, and advocates for a fair settlement that covers the full scope of necessary repairs. Our team has extensive experience navigating the commercial insurance claims process.
What is the advantage of a preventive maintenance program?
A preventive maintenance program catches small problems before they become expensive emergencies, extends the life of your roofing system, preserves warranty coverage that may require documented maintenance, reduces the risk of unexpected business disruption from leaks, and provides budgeting predictability through scheduled service rather than surprise repair bills. Most commercial roof failures are preventable with regular professional maintenance.
How long does a commercial roof replacement take?
The timeline depends on the size of the roof, the system being installed, and weather conditions. Small commercial projects may be completed in a few days, while larger buildings can take one to three weeks. Big Fish Roofing provides a detailed project timeline before work begins and schedules installation to minimize disruption to your business operations.
Can Big Fish Roofing work on occupied buildings?
Yes. Most of our commercial projects are completed while the building remains fully occupied and operational. We coordinate work schedules with building owners and tenants, manage noise and debris carefully, and maintain a safe work environment throughout the project. Minimizing disruption to your business is a priority on every commercial job.
What should I look for in a commercial roofing warranty?
A strong commercial roofing warranty should cover both materials and workmanship, clearly state the coverage period, define what is and is not included, and specify any maintenance requirements needed to keep the warranty valid. Manufacturer-backed warranties are stronger than contractor-only warranties because they are supported by the material manufacturer regardless of whether the installing contractor is still in business. As a GAF Master Elite Contractor, Big Fish Roofing offers manufacturer-backed warranty options for commercial projects.
Does Big Fish Roofing offer financing for commercial projects?
Yes. Big Fish Roofing offers financing options to help business owners and property managers manage the investment in a new commercial roofing system. We work with lending partners to provide competitive rates and flexible terms. Ask your project manager about available financing plans during your free inspection.
