A Curb For Every Tenant
Each storefront has its own rooftop unit, and every curb corner is another place for flashing to split.

As a Griffith commercial roof repair contractor, we fix leaking curbs, seams, and drains over retail strips and warehouses while the stores below stay open.
Griffith commercial roof repair on a retail strip means one long roof over many tenants, each with its own hours and its own rooftop unit.
A leak over one storefront usually starts at a curb, a drain, or a seam shared by the whole strip, and it can show up two doors down from where it enters. We trace it on the roof and inside the affected unit, with the tenant's hours in mind.
Owners get a short notice to pass along, and the noisiest steps run before stores open. Every unit curb on the strip gets checked while we are up there, because the next leak tends to start at the curb with the oldest sealant.

Strip roofs collect units, signs, and drains in long rows. These details fail most often.
Each storefront has its own rooftop unit, and every curb corner is another place for flashing to split.
A clogged drain between two units floods the roof above both, and the leak shows up in whichever store sits lower.
Long membrane runs carry seams the length of the building, and one open lap can drip into several tenant spaces.
Years of quick patches around old sign mounts and abandoned units leave edges that lift and hold water.
Restaurant and salon vents add pipe boots and fan curbs that crack in summer heat.
Water gets behind the front parapet at the coping and shows up inside the storefront window line.
On a strip roof, a repair can stay with one tenant bay or cover the whole run. This is how the scope gets set.
| Check | Repair One Bay | Repair The Whole Run |
|---|---|---|
| Leak location | One store, one source | Several stores along the same seam or drain line |
| Unit curbs | One curb cracked | Most curbs showing the same split corners |
| Drains | One strainer clogged | Drains slow along the full length |
| Old patches | A few still bonded | Patch edges lifting across the roof |
| Front parapet | One open coping joint over a store | Coping loose along the whole facade |
Repairs on a retail roof protect the tenants as much as the building.
Work from the roof and early-hour cutting let tenants keep serving customers below.
Fixing the shared drain or seam ends the leak in every store it was reaching.
Checking all unit curbs together avoids a new call each time a different tenant gets wet.
Photos and notes show what failed and where, which helps sort repair costs under each lease.
Send the strip address and which unit is wet. We trace it on the roof and inside that space.
Property somewhere else? Call us or send us a message. The towns below each have a repair page.
Office and multi-building roofs, inspected together in one visit.
Lake wind at edge metal and snow at the drains.
Metal roofs with skylights, ridge caps, and wall flashing.
Older shop roofs with years of patches to sort.
Strip repairs follow the tenants' schedule as much as the roof's.

You get a short notice with the date and work hours to send to each store under the roof.
The wet store gets checked first, then the curbs, drains, and seams above and uphill of it.
Cutting and other loud steps run early, and quieter sealing and patching continue through the day.
All unit curbs on the strip get a look so the next leak gets caught before a tenant calls.
Photos and notes come back labeled by storefront, so each tenant and the owner can see what was fixed above them.
Answers for strip center and warehouse owners in Griffith.
Yes. Flat roofs on Griffith warehouses, retail buildings, and offices get the same repairs we do in Portage.
That includes sealing seams, reflashing rooftop unit curbs, clearing drains, and patching punctures or blisters, all done from the roof so the businesses below can stay open. Curbs above restaurants and salons get extra attention for grease and vent residue.
The roof system, how many curbs and seams need work, and how hard the leak is to trace set most of the price.
Checking every curb on a strip in one visit costs less than separate calls each time a tenant reports water.
Our visits run from Portage to Griffith on a regular basis.
Send the address and which storefront or bay is leaking, and we will schedule a roof walk. A photo of the stained ceiling tile helps us find the right spot on the roof faster.
Ask whether they check every unit curb on the strip or only the one above the leak.
Also ask for photos, tenant-friendly hours, and a written list of what was repaired for your lease records.
The lease decides. Some leases make tenants responsible for their rooftop units and curbs, others keep the roof with the owner.
Our photos show exactly which detail failed, which makes that conversation easier. Each photo is labeled with the storefront below it and the roof detail involved.
Kitchen exhaust fans add grease residue and vibration, and both work on the membrane and curb flashing around the fan.
A residue-resistant patch around the fan and a reflashed curb hold up far longer than sealant smeared at the base.
They can. Brackets and conduit left from past tenants punch holes through the membrane and parapet, and their old sealant cracks.
Abandoned mounts get removed and the holes patched with matching membrane, or reflashed if the sign is still in use.

Tell us which tenant space is wet and how many units sit on the roof. We will trace it and price the repair.
