The Same Spot Leaks Again
A leak fixed last year is back in the same room.
Mastic was spread over a welded or taped roof and never stuck to it. Water runs underneath the old patch.

As a Boonville commercial roof repair contractor, we repair retail, municipal, and shop roofs across Warrick County, starting with the patches earlier repairs left behind.
Boonville commercial roof repair often starts with a roof that already carries years of patches in mixed materials.

Tar, mastic, tape, and membrane patches pile up as different roofers fix different leaks. Some never stuck to the roof below, and water runs under them. Knowing what each patch is decides how the new repair ties in.
We review past invoices, mark every old patch, and cut failed ones back to clean membrane. Each new repair gets photographed and located on a roof sketch, so the next roofer knows exactly what was done.
What old patches and humid summers leave behind.

New stains show up beside areas that were patched before.
A patch that ended short of firm membrane let water travel around its edge.
Leaks show up after long stretches of heat and humidity.
Heat ages sealant joints and membrane, then winter cold shrinks them, working seams and flashing loose.
Rust trails run down from screws in a metal shop or garage.
Humidity and age dried out the washers. New screws and washers go in along each row.
Nobody on staff remembers who repaired what or when.
We map each patch and record its material, so future repairs start from facts.

Answers on old patches, humidity, and coverage.
Coverage
Yes. We repair commercial roofs in Boonville, from retail and municipal buildings to metal shops and warehouses. If your building sits outside the towns on our list, call or send a message and we will tell you whether we can serve it.
Yes. Tenants and landlords both call us. We document what failed and where, so the people named in the lease have the same facts. Check your lease for who handles roof repairs before work is approved.
Weather
Heat and humidity age membranes and sealants and speed rust on metal roofs, while roofs swell in summer and shrink in winter. That cycle loosens seams, flashing, and screws. Checking seams, sealant joints, and fasteners each spring and fall catches the wear early.
Cost And Hiring
How many old patches need cutting out, the membrane type, wet insulation, the number of leak points, and access set the price. Roofs with heavy patch history take more prep before new material goes on. The estimate lists each repair area separately.
Ask how they handle old patches, whether they match the existing membrane, and how they record each repair. Ask for photos and a roof sketch with every repair marked. That record saves time and money on every repair after this one.
Send the address and any past repair invoices. We map the old patches and price the repairs in writing.
