Commercial Roofing Questions in Terre Haute

Look for a roofer that works on low-slope membranes and metal systems, inspects the roof before quoting, and explains the deck, insulation, and drainage plan in writing.

Ask how they will keep your building operating during the work and how they handle permits with the city. Compare scopes line by line as well as the totals.

TPO is a white, heat-welded membrane that reflects sunlight and suits buildings with cooling loads and lots of rooftop traffic. EPDM is a black rubber membrane with taped or adhered seams that stays flexible in cold weather and is simple to repair. Roof size, penetrations, budget, and the existing roof decide which fits.

It depends on the system, installation quality, drainage, and maintenance. Single-ply membranes such as TPO and EPDM often last 20 to 30 years, and metal roofs often last longer. Ponding water, foot traffic, and neglected flashings shorten that. Twice-yearly inspections and prompt repairs help a roof reach the long end of its range.

Roof size, the number of existing layers to tear off, deck repairs, insulation thickness, the membrane or panel chosen, and the number of curbs, drains, and penetrations all drive the price. Access, crane needs, and working around operations matter too. A free on-site estimate measures these and sets the price for your building.

Yes. Commercial roof replacement covers tear-off, deck repair, new insulation, and a new TPO, EPDM, or metal roof system with new flashings and edge metal. We stage replacement in sections so tenants and production can keep working, and we close each section watertight before the end of the day.

TPO (thermoplastic polyolefin) is a single-ply roofing membrane, usually white, installed over insulation on low-slope roofs. Its seams are fused with hot air into a continuous sheet. On a Terre Haute warehouse it is mechanically fastened or fully adhered, and it reflects summer sun to help keep the space below cooler.

TPO quality varies by manufacturer and thickness, and thinner sheets wear sooner. The white surface shows dirt and can be slippery when wet or frosty. Seams depend on correct welding temperature and speed, so crew skill matters. It is also less forgiving of sharp debris and dropped tools than thicker membranes.

On a large warehouse, TPO's welded seams and white surface suit long runs and high summer heat. EPDM's rubber holds up well in freezing weather and is easy to patch. TPO handles forklift-style rooftop traffic paths better with walkway pads; EPDM often costs less to repair. We compare both against your drainage and penetrations.

A robotic or hand-held hot-air welder melts the overlapping edges of two TPO sheets so they fuse into one piece.

We test-weld each morning to set temperature and speed for the day's weather, then probe every seam with a tool to find gaps. Welded seams do not rely on adhesive, which helps them hold through freeze-thaw.

EPDM is a synthetic rubber roofing membrane, usually black, used on low-slope commercial roofs. It comes in large sheets with few seams, which are joined with tape or adhesive. It stays flexible in cold weather, which suits west-central Indiana winters, and it is often used on offices, schools, and older flat-roof buildings.

The most common issues are seam tape or adhesive letting go, shrinkage pulling at corners and flashings, and punctures from foot traffic or debris. Flashings around curbs and drains often fail before the field sheet does. Most of these problems can be repaired if they are found before water saturates the insulation.

Fully adhered EPDM is glued to the insulation, giving a smooth surface that is easy to inspect and repair. Ballasted EPDM is held down by stone, which is faster to install but adds weight and hides leaks. The roof structure's load capacity and wind exposure usually decide which one fits your building.

When seams are failing in many places, the membrane is shrinking away from walls, or cores show wet insulation across large areas, replacement usually makes more sense than repair. We tear off the old system, repair the deck, add insulation, and install new EPDM or another membrane with new flashings.

Industrial roofing covers the large, low-slope roofs of plants, warehouses, and processing facilities, where heavy rooftop equipment, exhaust, and process heat put more stress on the roof. On a food processing plant it also means planning around clean areas, fresh-air intakes, and grease or steam exhaust that can attack some membranes.

We flash each curb, duct, and support with membrane or metal flashings tied into the field sheet, and we raise curbs when the new insulation makes them too short. Walkway pads protect the path to units that need service. We coordinate shutdowns of exhaust and makeup air units so presses stay running where possible.

We survey the roof, core-test insulation, and plan the work in sections around production. Each day's section is torn off, the deck is repaired, insulation and the new membrane or metal system go on, and the area is sealed before crews leave. Equipment curbs, drains, and edges get new flashings as each section is finished.

Expect a written safety plan for working at height near running equipment, a work schedule built around your shifts, and a clear plan for protecting product and machinery below. Contractors should explain the system, deck repairs, and how they will handle rooftop units. Ask for daily updates while crews are on the roof.
