Commercial roofing
built for the long haul

A commercial roofing contractor that protects what your business runs on

Your commercial roof is doing more than keeping rain out. It is protecting tenants, inventory, equipment, and operations that cannot afford to go offline. When the roof fails, the cost is rarely just the membrane. It is the lost productivity, the displaced tenants, the damaged finishes, and the emergency response that follows. The right commercial roofing partner prevents all of that long before it becomes a crisis.

Weddle & Sons has been installing, restoring, and maintaining commercial roofing systems since 1999. We work with property managers, building owners, facility directors, and capital planners who need a contractor they can rely on for one off projects, recurring maintenance, and long range portfolio planning. Every commercial customer gets the same locally operated attention to detail that built our residential reputation, with the systems and accountability a commercial scope demands.

Commercial roofing systems we install and service

Different buildings call for different systems. We install and service the full range of modern low slope and steep slope commercial roofing so the recommendation we make is based on what fits your building, your climate, and your hold period.

• TPO and PVC single ply membranes. The workhorse of modern commercial roofing. Energy efficient, highly reflective, and cost effective for retail, office, industrial, and warehouse buildings of any size.
• EPDM rubber roofing. Proven longevity for buildings where flexibility, chemical resistance, and freeze thaw performance matter.
• Standing seam metal. A 50 plus year solution for institutional, agricultural, and architectural commercial properties that want the longest service life available.
• Modified bitumen and built up systems. Multi ply redundancy for buildings with heavy foot traffic, complex penetrations, or specific code requirements.
• Silicone and acrylic restorative coatings. Seal leaks, restore reflectivity, and add ten or more years of service life without the cost or disruption of a full tear off.
• Commercial roof repair and emergency response. Active leak diagnosis, membrane patching, flashing repair, and storm damage stabilization, dispatched from our local offices.

TPO roofing: the modern standard for low slope commercial buildings

Thermoplastic polyolefin, better known as TPO, has become the dominant single ply membrane for commercial roofs in our region for good reason. It is bright white and highly reflective, which lowers cooling load and helps buildings hit energy code targets. It is heat welded at every seam, which creates a continuous watertight surface instead of relying on adhesives that can fail over time. And it is competitively priced against every other modern single ply system, so the budget math almost always works.

We install TPO from the major commercial manufacturers including GAF, Carlisle, and Johns Manville, with full mechanically attached, fully adhered, or induction welded assemblies depending on your building, wind zone, and warranty target. On most projects we specify 60 mil minimum membrane thickness because it qualifies for stronger NDL warranties and stands up better to foot traffic, hail, and rooftop equipment. For high traffic roofs or hail prone locations, we will recommend 80 mil and walk you through the warranty difference in writing before you decide.

Every TPO installation we do includes proper substrate prep, code compliant insulation and cover board, hot air welded seams that are probe tested before sign off, and detailed flashings around every penetration, curb, drain, and parapet. Cutting corners on any one of those steps is how cheap TPO roofs leak in year three. Doing them right is how a Weddle TPO roof lasts 25 plus years.

Roof coatings: extend the life of a roof you already own

If your existing commercial roof has years of life left but is showing wear, a manufacturer warrantied silicone or acrylic coating can be the single most cost effective decision you make this year. Our team inspects the existing system, performs the underlying repairs, primes where required, and applies a fully bonded coating that seals the surface, reflects heat, and reduces cooling load. The result is a watertight, energy efficient roof at a fraction of the cost of replacement, with a manufacturer warranty written specifically for your building.

Roof coatings work on a wider range of substrates than most owners realize. We coat aged TPO, EPDM, modified bitumen, built up, and metal roofs every year. Silicone coatings excel in ponding water conditions and resist UV breakdown indefinitely. Acrylic coatings are a strong fit for buildings in drier climates and where a lower up front cost matters more than ponding performance. Either way, the project usually finishes in days rather than weeks, your operation keeps running, and you avoid the disposal cost and disruption of a tear off.

Most restorative coating systems carry a 10, 15, or 20 year manufacturer warranty depending on the mil thickness applied and the underlying substrate. Many of our property manager customers also treat coating projects as a maintenance expense rather than a capital expense, which can change how the project gets approved and funded. We can model both paths during the estimate so you can take the right recommendation to ownership.

Capital planning and multi property programs

For property managers responsible for more than one building, we treat your portfolio like a long term partnership. That means annual condition assessments, written reports with photo documentation, prioritized capital recommendations, and projected service life on every roof. You get the visibility you need to budget intelligently and the heads up you need to avoid emergency replacements. When work is approved, the same Weddle team that wrote the report executes the project, so nothing gets lost in translation between vendors.

Commercial roof repair when you need it now

When a commercial roof is leaking on tenants, equipment, or finished space, the response time matters as much as the repair itself. Our service department prioritizes active commercial leaks, dispatches from the nearest local office, and can stabilize the roof the same day in most situations. From there we provide a clear written diagnosis, recommended permanent repair, and pricing you can take straight to ownership for approval.
