What We Repair

Commercial Roof Leaks We Repair in Louisville

Most commercial roof leaks in Louisville come from a short list of details. These are the repairs we make most often.

TPO and EPDM

Split or Lifted Seams

Seams take the most stress from heat, cold, and building movement. A probe finds the open lengths, which are rewelded or re-taped. Short open lengths are reworked the same visit they are found, before water spreads into the insulation.

Usually Means: The seam was welded cold or never primed

  • Pulled Base Flashing

    Flashing peels where the roof meets a wall or parapet, letting water run behind it.

  • Curb and Pipe Boot Leaks

    Unit curbs, pipe boots, and pitch pans dry out and crack at the seal.

  • Punctures and Cuts

    Service techs, dropped tools, and hail leave holes in single-ply roofs.

  • Clogged Drains and Scuppers

    Debris in strainers backs water up until it reaches seams and flashing.

Repair Options

Commercial Roof Repair Options for Louisville

Each repair matches the roof system already in place. Mixing materials that do not bond is a common reason a patched area leaks again.

Why Repair Now

Benefits of Commercial Roof Repair for Your Building

A prompt, well-matched repair protects more than the ceiling tile below the leak.

On The Roof

  • Steel Deck Protection

    Leaks left open rust the deck from the top down. Early repairs keep corrosion from spreading under the membrane.

  • Flashing Back in Place

    Rebuilt base flashing at walls and curbs stops water from running behind it and down the inside of the parapet.

Inside The Building

  • Insulation Stays Dry

    Closing the entry point quickly keeps water from soaking the boards around it, so fewer of them need replacing.

  • Business Keeps Running

    Most repairs happen from the roof surface while offices, stores, and warehouses below stay open.

For Planning And Budget

  • Replacement Pushed Back

    Targeted repairs on an otherwise healthy roof let you get the full service life out of it before planning a new one.

  • Clear Repair Records

    Photos of each repair and the detail it fixed give you a record to compare against the next inspection.

Active Leak Over Inventory or Equipment?

Call with where the water lands inside and what sits on the roof above. We make the area watertight first and plan the permanent repair around the weather.

Repair Process

How a Repair Visit Runs, Step by Step

Repairs follow a short order of work so the leak gets found, closed, and checked in one visit when the weather allows.

  1. Inspect Your Roof

    We start above the stain inside, then follow the water path across the roof to the seam, curb, or flashing where it enters.

  2. Check the Insulation

    Moisture readings and a small core show whether the boards under the leak are wet and how far the water has spread.

  3. Make the Repair

    The failed detail is cleaned, primed, and closed with matching membrane, tape, or flashing, and wet boards are swapped out.

  4. Test and Report

    New seams are probed, and you get photos of the before and after with any other weak spots we noticed.

Leak Tracing

Where Louisville Commercial Roof Repair Starts

A stain on a ceiling tile shows where water lands, which can be ten or twenty feet from where it gets in. On a Louisville warehouse or office, the water usually enters at a seam, a curb, a drain, or a wall flashing, then runs along the deck before it drips.

We follow that path on the roof, confirm it with moisture readings, and open a small core if the insulation looks wet. The repair goes where the water enters, and the wet boards around it get replaced.

  • Interior stain located and measured
  • Water path followed on the roof
  • Moisture readings around the entry point
  • Repair matched to the existing membrane

Louisville Commercial Roof Repair Questions

Answers about leaks, repair timing, and what changes the price of a repair.

Roof Condition

How do I know if my commercial roof needs repair or replacement?

Look at how far the problem spreads. If leaks trace to a few seams or curbs and core samples nearby come up dry, a repair fixes it. If wet insulation shows up across large areas, or the membrane is cracking everywhere, replacement is the better spend.

What causes most commercial roof leaks in Louisville?

Details cause most of them: open seams, flashing pulling away at parapets and rooftop units, clogged drains, and punctures from service traffic. Older brick buildings near downtown Louisville add worn counterflashing in the masonry, which lets water in behind the base flashing.

Membranes and Systems

Do you repair roofs installed by another contractor?

Yes. Most of the roofs we repair around Louisville were installed by someone else. We identify the membrane or metal system first, then use materials and methods that bond to it, so the repair holds alongside the original roof.

How quickly can a leaking seam be repaired?

Most seam repairs on TPO and EPDM roofs are finished in a single visit once the leak is traced, as long as the surface is dry. Larger wet areas take longer because the soaked insulation is cut out and replaced first.

Planning the Work

What affects the cost of a commercial roof repair?

Four things drive it: how big the damaged area is, what caused it, whether insulation underneath is wet, and how hard the spot is to reach. A single seam weld is a short visit; replacing a wet section of insulation and membrane takes materials and more labor.

Can a leaking flat roof be repaired in winter?

Yes, in most cases. A dry surface and cold-rated adhesives or welding equipment allow many single-ply repairs in winter. When a permanent repair needs warmer weather, we seal the area watertight first and return on the next suitable dry day.
