Why Choose Valiant Roofing?
Commercial roofs fail in ways that cost you far more than the roof itself: inventory, downtime, tenants, insurance headaches. We build and repair roofs that are made for Wisconsin winters, and we do it with materials and details that hold up long after the crew leaves. Here is why property owners and facility managers keep calling us back.
- EPDM and flat roof specialists. Most of the low slope roofs we install are EPDM rubber. We know how these systems behave in deep cold, how the seams and flashings actually fail, and what it takes to make them last decades instead of years.
- Every commercial system under one roof. EPDM, TPO membrane, metal, and architectural shingles for apartment complexes, churches and other large buildings. We recommend the system your building needs, not the one we happen to sell.
- Built for Wisconsin weather. Snow load, ice damming, wind uplift and hard freeze thaw cycles drive every detail we install, from fastener patterns to snow retention on metal roofs.
- Quality you can inspect. Premium materials, manufacturer approved details, tidy work and a final walk through with you before we call the job finished.
- A team that answers the phone. You get direct communication from estimate to final invoice, plus emergency response when something goes wrong at the worst possible time.
Commercial Roofing Systems We Install
Flat and low slope roofs dominate commercial construction for good reason, and the membrane you put on top of them decides how the building performs for the next thirty years. Here is a plain English look at the systems we install most, and where each one makes sense.
Flat Roofing Systems
- Efficient installation. Fewer materials and faster install time keep costs down compared with a framed steep slope roof.
- Easy maintenance access. A level surface makes inspections, service calls and equipment work safe and straightforward.
- Usable space. Rooftop equipment, solar arrays and green roof assemblies all mount cleanly on a properly built flat roof.
- Drainage first. Every flat roof we build is designed around positive drainage, because standing water is what kills low slope roofs early.
EPDM Rubber Roofing (our most requested commercial system)
EPDM is the black rubber membrane you see on the majority of commercial and apartment roofs across the Midwest, and it is the system we install most. It is a single ply synthetic rubber sheet that stays flexible in extreme cold, moves with the building instead of cracking, and can be repaired or restored decades into its life.
- Made for cold climates. EPDM stays pliable in subzero temperatures and handles the constant freeze thaw expansion that pulls Wisconsin buildings apart.
- Long service life. A properly installed EPDM roof commonly delivers 25 to 30 years of service, and the membrane itself is one of the most field proven materials in the industry.
- Dark surface, real winter advantage. The black membrane absorbs solar heat, which helps shed snow and ice load rather than holding it on the roof all winter.
- Fewer seams, fewer problems. EPDM comes in wide sheets, so there is less seam length across the roof than most alternatives, and seams are where roofs leak.
- Simple, affordable repairs. Damage is patched cleanly and permanently, which makes EPDM one of the easiest systems to maintain over the long run.
- Installed to fit the building. Fully adhered, mechanically attached or ballasted, depending on your structure, exposure and budget.
TPO Roofing Systems
TPO is a white thermoplastic single ply membrane and a strong option on buildings where cooling costs and heat gain are the bigger concern. We install it when the building calls for it.
- Reflective and energy efficient. The white surface reflects sunlight and reduces heat absorption, which lowers summer cooling loads.
- Durable membrane. TPO resists UV exposure, many chemicals and punctures, and holds up well in harsh weather.
- Heat welded seams. Seams are hot air welded into a continuous bond rather than adhered.
- Recyclable. TPO is a recyclable material and contributes to a lower carbon footprint.
- Flexible. The membrane accommodates building movement without cracking.
When we recommend TPO instead of EPDM: buildings with heavy cooling demand, restaurants and refrigeration, grease exposure, large unshaded roof areas, or ownership groups with a reflective roof requirement.
Commercial Metal Roofing
Metal is the longest lasting roof we install, and in snow country it earns its keep. We handle standing seam and exposed fastener systems on commercial, agricultural, municipal and mixed use buildings.
- Decades of service. A quality metal roof routinely outlasts two or three shingle roofs.
- Sheds snow and ice. Smooth panels shed load instead of trapping it, and we add snow retention where people, entries or equipment sit below.
- Wind and fire performance. Properly fastened metal panels handle high wind events and carry excellent fire ratings.
- Low maintenance. No granule loss, no seasonal patching, minimal upkeep beyond fastener and sealant checks.
- Color and profile options. Panel profiles and finishes that match your brand or your building’s architecture.
Asphalt Shingles for Large Buildings
For steep slope commercial properties, shingles are still the right call. We take on shingle work at scale: apartment and condo complexes, churches, schools, lodges and multi building properties.
- Built for occupied buildings. We phase the work building by building so tenants, congregations and staff stay safe and access stays open.
- Architectural shingle systems. Heavier profile shingles with full ice and water protection at eaves and valleys, correct ventilation and manufacturer backed warranties.
- Large project management. Dumpster staging, material drops, daily cleanup and a schedule your property manager can plan around.
- Insurance work handled. Storm and hail damage documented and coordinated with your carrier.
Which Commercial Roof Is Right for Your Building?
There is no single best commercial roof, only the right one for your structure, your climate exposure and how long you plan to hold the property. Here is how we usually guide the decision.
- Choose EPDM rubber if you have a flat or low slope roof in a cold climate, you want proven long term performance and easy repairs, and you want the best balance of cost and service life. This is the right answer for most Wisconsin commercial and apartment buildings.
- Choose TPO if cooling costs, heat gain or a reflective white surface are priorities, or your building has grease, chemical or refrigeration exposure.
- Choose metal if you want the longest possible service life, you want snow and ice to shed rather than sit, or the building has enough slope to show the roof off.
- Choose architectural shingles if the building is steep slope: apartments, condos, churches, lodges and similar properties where a membrane is not an option.
Not sure which one fits? We will get on the roof, take a look at what is actually up there, and tell you straight.
Our Services
Valiant Roofing covers the full life of your commercial roof, from the first inspection to the day it needs replacing.
Roof Inspections
Small problems on a flat roof stay invisible until they reach your ceiling tiles. We inspect seams, flashings, penetrations, drains and edge metal, document what we find with photos, and give you a clear picture of your roof’s condition and remaining life.
Roof Repairs
Leaks, storm damage, failed seams, punctured membrane, blown flashing. Our crews repair EPDM, TPO, metal and shingle systems with materials that match what is already on your building, so the fix lasts.
Roof Replacements
When repairs stop making financial sense, we replace the system with the one your building actually needs, on a schedule built around keeping your business running.
Emergency Services
Storms do not wait for business hours. We respond fast to stop active leaks, dry the building in, and protect your property and your inventory from further damage.
The Valiant Roofing Process
Our process is built to keep you informed and your building operating from start to finish.
- Consultation. We start with a conversation about your building, your timeline, your budget and any history of problems.
- Inspection and Diagnosis. We get on the roof and document the real condition of the membrane, flashings, drainage and deck, then recommend repair or replacement based on what we find.
- Proposal and Agreement. A detailed proposal covering scope, materials, system, timeline and cost. No surprises later.
- Execution. Our crew builds the roof to manufacturer specification, keeps the site clean and safe, and works around your operating hours where needed.
- Final Inspection and Handover. We walk the finished roof with you, review the warranty, and leave you with documentation of the completed work.
