Commercial Roofing Services in Jeffersontown

Start with slope: membranes cover low-slope roofs, metal panels need more pitch, and the building code and each maker's instructions set the minimums. Then weigh use. A flat roof crowded with units points to TPO or EPDM, a pitched steel frame to standing seam or R-panel, and heavy cooling loads to white TPO or a light metal finish.

It can. IRS Publication 946 lists roofs on existing nonresidential buildings as qualified real property, next to HVAC, fire protection, and security systems. The 2026 maximum is $2,560,000, with phase-out above $4,090,000 in qualifying purchases. Residential rental property is excluded, and a CPA decides how your replacement is treated.

Once the problems spread across the roof. Wet insulation over large areas, seams failing in many places, and a membrane that cracks when folded point to replacement, while a few open seams or one wet corner point to repair. A moisture survey and core cuts show the reach first.

A tear-off removes every layer down to the deck, so it brings a large dumpster, more haul-off, and more interruption inside. A recover puts a new roof over a dry existing one and hauls far less. The code rules out recovers over wet or badly deteriorated roofs and over roofs that already carry a recover layer.

Wet insulation holds daytime heat, so an evening infrared scan shows it as warmer patches than the dry roof around it. Core cuts then confirm each patch: the number of layers, the insulation type and thickness, its moisture, and the deck below. Every core is patched before the crew leaves.

They are usually replaced with the membrane, because the new surface sits at a different height and old metal often has loose cleats. Gravel stops become cleated edge metal, coping is reset, counterflashing is cut into masonry, and gutters are resized. New edge metal follows a tested wind design that the code references.

Units run as long as possible, then a licensed mechanical trade disconnects, lifts, and resets them when the crew reaches their curbs. Curbs left too short by added insulation get an extension or adapter, abandoned curbs come out and get decked over, and a unit being replaced gets its new curb before the membrane.
