How We Work

A structured approach from inspection through finish ensures your roof is installed right.

Diagnose What Needs to Happen

We inspect your roof's condition, measure the footprint, and assess building access. This step identifies structural needs, material choices, and local permit requirements for Fontana commercial properties.

Prepare a Clear Plan

We outline the scope, material specs, and workflow. You'll know what to expect before work begins and understand how installation minimizes disruption to your business operations.

Perform the Replacement

Our crew removes the old roof system, addresses any underlying damage, and installs new materials to code. We manage debris, protect site safety, and keep the work organized throughout.

Verify Everything Works

We test all seams, flashing, and drainage points. A final walkthrough confirms the roof meets local standards and performs as designed.

You'll always know what's happening next—and when.

Our Services

Commercial roof replacement tailored to Fontana's industrial and retail sectors.

Full Membrane Systems

TPO, EPDM, and PVC membranes suit large-span industrial and warehouse facilities. These systems offer reliable weatherproofing for the intense sun and occasional heavy rain Fontana buildings experience.

Full TPO membrane install on a Southwest Industrial Park warehouse.

Membrane roofs resist UV damage and adapt to seasonal temperature swings. Installation includes base sheets, insulation layers, and sealed seams that keep water out for decades.

Metal Roof Systems

Standing-seam and corrugated metal roofs deliver strength for buildings in Downtown Fontana and surrounding commercial zones. Lightweight, reflective, and long-lasting, metal performs well in full-sun exposures.

Metal roofs shed snow and ice, allow easy drainage, and come in multiple finishes. We install fasteners, flashing, and ridge caps to spec, with all seams locked tight against water entry.

Modified Bitumen & Built-Up Roofs

For older commercial buildings or specific load needs, modified bitumen and built-up systems offer proven durability. We replace or upgrade these layers on structures across all Fontana neighborhoods.

These methods handle moderate roof slopes and accept future roof-mounted equipment without compromising integrity.

Why It Matters

A sound roof protects your building, assets, and operations every day.

Avoid Costly Water Damage

Leaks lead to mold, structural rot, and inventory loss. A properly installed roof eliminates these risks and keeps your business running without interruption or insurance claims.

One undetected roof leak can cost tens of thousands in repair, remediation, and downtime.

Meet Building & Insurance Requirements

Fontana building codes mandate roof systems that match your structure's design load and wind rating. Insurance may require a new roof or documentation of a compliant installation. We ensure your replacement passes all inspections and satisfies underwriter standards.

Secure Long-Term Performance

A new roof system installed to spec lasts 20–40 years depending on material and maintenance. You avoid repeated repairs and gain years of worry-free protection.

What Does a Commercial Roof Replacement Cost to Estimate?

Cost depends on roof size, material choice, and removal complexity. TPO membranes, standing-seam metal, and built-up systems each carry different material and labor costs.

Small warehouse (5,000–15,000 sq. ft.): budget for basic inspection and material quotes first
Mid-sized retail or mixed-use (15,000–50,000 sq. ft.): complexity increases with roof penetrations and load requirements
Large industrial (50,000+ sq. ft.): phased installations may apply; site access and logistical factors influence price

Always get a detailed site assessment before committing to any figure.

Frequently Asked Questions

Common questions about commercial roof replacement in Fontana.

When should we replace our commercial roof?

Replace your roof if it shows widespread leaks, sagging, visible membrane damage, or is nearing the end of its lifespan (15–25 years depending on material). An inspection will confirm whether repair or replacement is the right call.

Do we need a permit for roof replacement in Fontana?

Yes. City of Fontana requires permits for commercial roof work. We handle all permitting, inspections, and code compliance so your project stays legal and properly documented.

Can we install a new roof over the old one?

Sometimes. Overlay installations are possible on some systems but not others. If the old roof is deteriorated, wet, or structurally compromised, removal is required. We assess your roof and recommend the best approach.

How do weather and UV affect commercial roofs in Fontana?

Fontana's intense sun and occasional heavy rain accelerate material breakdown. UV exposure weakens membranes and coatings over time. Metal roofs resist UV better than bitumen; reflective coatings extend all system lifespans.

What happens if my roof fails during or after installation?

Our installation includes testing all seams, flashing, and drainage before final sign-off. We stand behind our workmanship and address any issues that arise from installation defects.

Can roof replacement affect my business insurance?

A new roof typically lowers your insurance premium and may satisfy policy requirements. Some carriers offer discounts for recent replacements. Contact your insurer to discuss rate adjustments after the project.
