What Is Commercial Roofing and How Does It Work?
Commercial roofing is the process of installing or restoring low-slope roofing systems on buildings like warehouses, offices, and retail spaces. Unlike steep-slope residential roofs, commercial roofs use membranes such as TPO, EPDM, or modified bitumen, which are designed to shed water with minimal pitch. A typical installation begins with a roof asset survey, where we inspect the roof deck, insulation, and parapet to identify any rot or decay. We then prepare the surface, install a self-adhered underlayment, and lay the membrane in staggered courses, using ring-shank nails or heat-welding seams depending on the material. The goal is a watertight barrier that withstands Novato's foggy mornings, heavy winter rains, and hot, dry summers.
For property managers and facility directors, commercial roofing involves more than just materials—it requires coordination with tenants and compliance with local building codes. We handle the entire process, from obtaining permits to scheduling work during off-hours to minimize disruption. Whether you need a full tear-off or a recover over an existing roof, we'll recommend the system that fits your building's structure and your long-term budget. With warranties ranging from 15 to 30 years on most single-ply systems, you can count on lasting protection.
When Do You Need Commercial Roof Repair or Replacement?
Commercial roof repair is necessary when you notice leaks, ponding water, or visible membrane damage. Water can seep through small punctures and wick along the insulation, causing rot and decay that compromise the roof deck. If you see granule loss on a built-up roof, or the membrane is delaminating at the seams, it's time to act. Other signs include blistering, alligatoring, or widespread cracking—all indicators of end-of-life wear. Ignoring these issues leads to costly interior damage, mold, and even structural sag. If your roof is over 20 years old or has experienced storm damage, a professional inspection can determine whether repair or replacement is more cost-effective.
For commercial roofing, we recommend a roof asset survey every year, especially after heavy storms. This proactive approach catches small problems before they escalate. When repair is possible, we use techniques like patching, resealing flashing, or applying a coating to extend the roof's life. If replacement is the better option, we'll guide you through material choices—TPO for energy efficiency, EPDM for budget-friendly durability, or modified bitumen for high-traffic roofs. We also assist with insurance claims, helping you document storm damage and navigate the adjuster inspection. Our goal is honest communication about what your roof needs, so you can make an informed decision.
How to Choose a Novato Roofing Contractor for Commercial Projects
Choosing the right Novato roofing contractor for your commercial project starts with verifying credentials. Look for a licensed and insured roofing company with experience in low-slope systems like TPO, EPDM, and built-up roofing. Ask about their process—do they perform a thorough roof asset survey before quoting? Do they provide line-item estimates that explain costs? A reputable contractor will walk you through the scope of work, including tear-off, deck repair, and flashing details. They should also be familiar with local building codes and manufacturer requirements for warranty validity.

Frequently Asked Questions About Commercial Roofing
What is the lifespan of a commercial roof?
Commercial roofing systems typically last 20 to 30 years, depending on the material and maintenance. TPO and EPDM membranes offer 20-25 years, while modified bitumen can last up to 30 years with proper care. Regular inspections and prompt repairs extend your roof's life significantly.
How much does commercial roof replacement cost?
Commercial roof replacement costs vary based on square footage, material, and roof complexity. On average, expect to pay between $5 and $12 per square foot for TPO or EPDM, and more for built-up roofing. We provide free, detailed estimates after a roof asset survey, so you know exactly what to budget.
Can you repair a commercial roof instead of replacing it?
Yes, commercial roof repair is often possible if the damage is localized and the membrane is still in good condition. We can patch punctures, reseal seams, or apply a coating to restore waterproofing. If the roof has widespread decay or end-of-life wear, replacement may be more cost-effective long-term.
