Commercial roofing covers the flat and low-slope roof systems used on business, industrial, and government buildings — and in 2026 a commercial roof replacement in Texas typically costs $7.50 to $16.00 per square foot installed, depending on the material. This guide from Montgomery Roofing explains the main commercial roofing systems, what they cost, how long they last, and how to choose the right commercial roofing contractor in Central Texas.
What is commercial roofing?
Commercial roofing is the installation, repair, and maintenance of roofs on commercial buildings such as offices, warehouses, retail centers, restaurants, and government facilities. Unlike the sloped, shingled roofs on most homes, commercial roofs are usually flat or low-slope and use membrane or metal systems like TPO, PVC, EPDM, modified bitumen, or standing-seam metal. These systems are built for large surface areas, foot traffic, rooftop equipment, and drainage.
How much does a commercial roof cost in Texas?
A commercial roof replacement in Texas costs about $7.50 to $16.00 per square foot installed in 2026. Price depends mainly on the material and the condition of the existing roof. By system: single-ply membranes such as TPO and PVC run roughly $8.00 to $14.50 per square foot, EPDM (rubber) runs about $7.00 to $12.50, and metal roofing systems run about $12.00 to $22.00. Tear-off of the old roof, new insulation, drainage corrections, and code upgrades can push the total higher.
What is the best commercial roofing material?
There is no single best commercial roofing material — the right choice depends on your building, budget, and climate. TPO is popular for its energy efficiency and reflectivity, which helps in the Texas heat. PVC offers excellent chemical and fire resistance, making it ideal for restaurants. EPDM (rubber) is durable and cost-effective for large flat roofs. Metal roofing lasts the longest, often 40 to 50 years. Modified bitumen and roof coatings are strong options for restoration. A commercial roofer can recommend the best system after inspecting your roof.
Why do commercial buildings have flat roofs?
Commercial buildings have flat roofs because they are more cost-effective and practical for large structures. Flat roofs are cheaper to build over a wide footprint, provide space for HVAC units, solar panels, and other equipment, and are safer and easier to access for maintenance. Modern flat commercial roofs are not perfectly level — they include a slight slope so water drains toward internal drains or scuppers.
What is the lifespan of a commercial roof?
Most commercial roofs last 20 to 30 years, though lifespan varies by material. TPO and PVC membranes typically last 20 to 30 years, EPDM around 20 to 25 years, and metal roofing 40 to 50 years or more. Regular inspections, prompt repairs, and preventive maintenance are the biggest factors in reaching the upper end of that range.
How much does a commercial roof inspection cost?
A commercial roof inspection typically costs a few hundred dollars, though many commercial roofing contractors — including Montgomery Roofing — offer free inspections and estimates. A professional roof inspection documents the roof’s condition, identifies leaks and damage, and helps you plan repairs or budget for replacement before small problems become expensive ones.
How often should a commercial roof be inspected?
A commercial roof should be inspected at least twice a year — typically in spring and fall — plus after any major storm. In Central Texas, where hail, high winds, and intense summer heat are common, regular inspections catch damage early and are a core part of any preventive maintenance program. Twice-yearly inspections help extend roof life and avoid emergency repairs.
How do you choose a good commercial roofing contractor?
To choose a good commercial roofing contractor, look for a company that is fully insured and bonded, has strong local experience and reviews, specializes in commercial systems (not just residential), provides detailed written estimates, and offers solid workmanship and material warranties. Ask about their experience with your specific roof type and request references from local commercial clients. Montgomery Roofing has served Central Texas businesses for over 25 years and is fully bonded and insured.
How do you fix a commercial roof leak?
Fixing a commercial roof leak starts with a professional inspection to find the true source, which is often away from where the water appears inside. Common fixes include resealing seams and flashing, patching membrane punctures, repairing damaged drains or scuppers, and re-coating worn areas. For older roofs with widespread damage, a restoration coating or replacement may be more cost-effective than repeated repairs.
