Lake Station Commercial Roof Repair On Patched Roofs
Lake Station commercial roof repair often starts on a roof that already carries a decade of patches from different hands.
Old patches tell a story. Some still bond tightly and can stay; others hold water at their edges and feed the leak you are chasing now. Many were laid with asphalt cement over single-ply membrane, which softens the sheet underneath and lets the patch slide off over time.
We test each patch area, core the ones that feel soft, and give you a map of which patches to keep, which to replace, and where the real leak sits. Wet board under failed patches comes out so new repairs go down on dry insulation.

Commercial Roof Repair Problems On Lake Station Shop Roofs
Older shop and storage roofs show the same signs of patch-on-patch repair.
Wet Insulation
Soft Spots Under Old Repairs
Patches set over wet board keep the moisture in, and the soft area grows a little each season.
Mixed Materials
Incompatible Repair Materials
Asphalt mastic smeared on single-ply membrane breaks down the sheet and lets the patch slide.
Drains
Drains Raised By Repairs
Repeated layers around a drain lift the roof surface above the bowl, so water pools instead of draining.
Curbs
Old Curbs Sealed By Hand
Curbs on older units carry hand-troweled sealant instead of flashing, and it cracks every winter.
Metal Sections
Rusted Screws On Shop Additions
Metal additions on older shops lose washers and rust at the laps where they tie into the flat roof.
Lake Station Commercial Roof Repair: Keep, Patch, Or Replace
On a heavily patched roof, the call gets made patch by patch before it gets made for the whole roof.
| Check | Keep Or Repair | Time For A New Roof |
|---|---|---|
| Patch bond | Most patches tight at the edges | Most patches lifting or holding water |
| Moisture | Wet board in a few small areas | Wet board under most patch zones |
| Materials | Patches match the membrane | Mixed mastics and sheets everywhere |
| Drains | Drains still sit low | Drains buried by repair layers |
| Curbs | Flashed curbs with sealed corners | Hand-sealed curbs cracked all around |

Lake Station Commercial Roof Repair Questions
Answers for owners of older shop, storage, and light industrial roofs.
Industrial Roofs
Do you repair industrial roofs in Lake Station?
Yes. Industrial and commercial roofs in Lake Station are part of our work, from shops and storage buildings to light industrial properties.
We trace leaks, repair failed seams, curbs, and drains, and replace wet insulation, with the work scheduled around operations inside the building.
Businesses
How does commercial roof repair for Lake Station businesses handle old patches?
Every old patch gets tested for bond and moisture before deciding whether it stays.
Patches that hold are left alone, failing ones come out with any wet board beneath them, and the real leak gets a matched repair. The keep-or-replace list comes with photos of every patch area we tested.
Finding Help
Where can I find Lake Station commercial roof repair near me?
Lake Station sits right next to Portage, so visits there are short trips for us.
Call or request an estimate with the address and how long the roof has been leaking. A short note on past patches, and who laid them, helps us plan the first roof walk.
Contractors
How do I pick a commercial roof repair contractor near Lake Station?
Choose one who traces the leak before patching and explains which old repairs can stay.
Ask for photos and a list of what was removed, so the next repair starts from a known record. That record keeps the next roofer from patching over a seam that already failed twice.
Mastic
Is roof cement over a membrane a problem?
Often, yes. Asphalt-based cement softens single-ply membranes like TPO and EPDM, and the patch eventually slides or lifts.
We cut out the mastic, clean the sheet, and patch with matching membrane so the repair bonds.
How Long
How long can repairs carry an older roof?
That depends on how much of the roof is dry and how many patches still bond.
A roof with a few wet spots and solid patches can run several more seasons on repairs. One where most patch zones are wet is closer to replacement, and the moisture readings will show it.
Storage Buildings
Do unheated storage buildings need different repairs?
The methods match, but timing matters more, since cold decks make welding and adhesives harder in winter.
Leaks get temporary seals in cold months, and full membrane repairs go in once the deck warms up in spring.
