Commercial Roofing

A commercial roof protects more than a building — it protects your business, your employees, your inventory, and your revenue. In Austin’s punishing climate, where flat and low-slope roofs absorb extreme heat, withstand hail impacts, and manage heavy rainfall, a compromised commercial roof quickly becomes a business interruption. Onward Home provides commercial roofing services for Austin businesses — from retail storefronts and office buildings to warehouses, HOA properties, and multi-family complexes.

Why Austin Businesses Need Commercial Roofing Services

Commercial roofs in Central Texas face the same extreme conditions as residential roofs — but with additional challenges. Most commercial buildings use flat or low-slope roof systems that must handle ponding water after heavy rains, resist thermal expansion across large surface areas, and maintain waterproof integrity under constant UV exposure. A 10,000-square-foot commercial roof absorbs significantly more solar heat than a pitched residential roof, placing enormous stress on membrane materials and seam integrity.

Energy costs are a major factor for Austin businesses. According to Austin Energy data, cooling represents the largest portion of commercial energy consumption in the Austin metro. An aging or poorly insulated commercial roof drives up HVAC costs substantially. Modern cool-roof systems — including reflective TPO and coated metal — can reduce rooftop surface temperatures by 50–60°F and lower cooling energy usage by 10–30%.

Beyond energy and weather, commercial roofs must meet building codes, fire ratings, and warranty requirements that differ from residential standards. Texas commercial building codes require specific wind uplift ratings, fire classifications, and drainage standards. Working with a licensed commercial roofing contractor who understands these requirements protects your investment and avoids code violations.

Our Commercial Roofing Process

1. Free Commercial Roof Assessment — We perform a comprehensive inspection of your commercial roof, including membrane condition, seam integrity, flashing and penetration seals, drainage performance, and insulation. We use infrared moisture scanning when appropriate to identify trapped moisture beneath the membrane. The assessment includes a written condition report with photos.
2. Scope & Proposal — Based on the assessment, we present options ranging from targeted repair to full replacement, including material recommendations, energy efficiency improvements, and budget-conscious alternatives. Our proposals include itemized pricing, projected timelines, and warranty details.
3. Minimal Disruption Scheduling — We schedule work to minimize impact on your business operations. For occupied buildings, we can phase the project by sections, schedule work during off-hours or weekends, and coordinate with property managers and tenants.
4. Professional Installation — Our commercial crews are trained in flat roof membrane systems, metal panel installation, and coating applications. We follow manufacturer specifications for every product and meet all City of Austin commercial building code requirements.
5. Project Documentation — Upon completion, we provide a full documentation package: as-built drawings, warranty certificates, maintenance recommendations, and permit close-out. This documentation is essential for property management records and future roof maintenance planning.

Types of Commercial Roofing We Offer

TPO (Thermoplastic Polyolefin)

TPO is the most widely installed commercial roofing membrane in Texas. It offers excellent heat reflectivity, strong weld seams, and resistance to UV, ozone, and chemical exposure. TPO is available in white, gray, and tan — with white being the most energy-efficient option for Austin’s climate. Typical lifespan is 20 to 30 years.

Metal Roofing for Commercial Buildings

Standing seam and exposed-fastener metal panels are popular for retail, restaurant, and mixed-use commercial buildings in Austin. Metal roofs provide 40+ year lifespans, superior wind resistance, and significant energy savings through solar reflectance. We install structural and architectural metal systems in steel, aluminum, and galvalume.

Modified Bitumen

Modified bitumen is a layered asphalt-based system well-suited for flat commercial roofs that need to handle foot traffic (HVAC servicing, rooftop equipment maintenance). It provides excellent waterproofing, puncture resistance, and a 15- to 20-year lifespan. Cap sheets are available in reflective finishes to improve energy performance.

Roof Coatings

Silicone and acrylic roof coatings can extend the life of an existing commercial roof by 10 to 15 years at a fraction of the cost of full replacement. Coatings are applied directly over the existing membrane, providing renewed waterproofing and UV protection. This is an excellent option for roofs that are aging but not yet leaking.

Multi-Family and HOA Roofing

We serve apartment complexes, condominiums, and HOA communities across the Austin metro. Multi-family projects require coordination with property managers, tenant communication, phased scheduling, and consistent quality across multiple units. We handle all aspects of multi-unit roofing projects from initial assessment through warranty documentation.

Frequently Asked Questions

How long does a commercial roof replacement take?

Timeline depends on the building size, material, and complexity. A 5,000-square-foot TPO replacement typically takes 3 to 5 days. Larger projects (10,000+ square feet) may take 1 to 3 weeks. Metal roof installations generally take longer due to panel fabrication lead times. We provide a specific timeline in our proposal and keep you updated throughout the project.

What is the best commercial roofing material for Austin?

For flat and low-slope commercial roofs in Austin, TPO is the most popular choice due to its heat reflectivity, durability, and cost-effectiveness. For buildings seeking maximum lifespan, standing seam metal is the premium option. The best choice depends on your building type, budget, energy goals, and aesthetic preferences. We assess your specific situation and recommend the most appropriate material.

Can you repair my commercial roof instead of replacing it?

In many cases, yes. If the membrane is generally intact and damage is localized — around penetrations, at seams, or in low spots — targeted repair can extend the roof’s life significantly. Roof coatings are another effective option for aging but functional roofs. We always present repair options alongside replacement so you can make an informed decision.

Do commercial roofs require regular maintenance?

Yes. We recommend semi-annual commercial roof inspections — once in spring (before storm season) and once in fall (before winter). Regular maintenance includes clearing drains, resealing penetrations, inspecting seams, and addressing minor issues before they become major problems. A proactive maintenance program can extend your roof’s lifespan by 5 to 10 years.
