Leaks at Tenant Units
Every storefront adds a rooftop unit and a curb. Cracked curb flashing is the first thing we check when one tenant reports a drip.
As a Ralston metal roof coating contractor, we coat strip-center and small commercial roofs while every storefront below stays open.

Ralston metal roof coating work usually lands on a shared roof over several tenants. Coating happens from the roof surface with no tear-off, so the shops, salons, and offices below keep their doors open.
The planning is about people: when tenants open, where they park, and which rooftop unit cools which space.

Strip-center roofs collect the same four problems. Each one gets fixed before we coat.

Long strip roofs carry panel laps across several tenant spaces. One open lap can drip into the space next door, so we trace water along the rib.
Rear gutters fill with debris from the alley side. Water backs up under the end laps until the gutter is cleared.
A stained tile inside one shop often traces to a penetration two bays uphill. We follow the stain from inside before climbing up.
Storefront parapets catch hail on their caps and coping. Split coping seams let water behind the facade, so we reseal them along with the roof.
Many rows share one roof hatch inside a single tenant's space. We arrange access with that tenant so ladders and materials pass through at set times.
For a multi-tenant roof, coating keeps every lease space open. Here is how it compares with replacing the roof.
| Roof Factor | Coat The Roof | Replace The Roof |
|---|---|---|
| Storefronts during work | Open all day | Spaces exposed under tear-off |
| Tenant notice | Dates and quiet hours shared ahead | Longer disruption to plan around |
| Rooftop units | Shut down one section at a time | Disconnected and reset |
| Planning cost | About $2.50 to $4.00 per sq ft | About $5 to $8 per sq ft |
| Parking lot | One small staging area | Dumpsters and lift traffic |
Each system below fits a different part of a Ralston commercial row.

Exposed-fastener panels over a row of shops get every screw, lap, and rust spot handled first, then primer and a full coating that runs continuously across each tenant's section.

Flat back sections behind the storefront parapet that pond after rain take silicone, once the rear scuppers and gutters on the alley side are cleared and tested.

Pitched front canopies that drain quickly take acrylic in a light color, applied on dry, mild days so the coat cures before evening dew settles on the panels.

A tenant space that runs cold in winter can take foam on its own section of roof, with a UV topcoat and the rooftop unit intake masked during spraying.

Shingled mansard fronts along the row get a shingle coating in the same mobilization, after lifted tabs are sealed and the flashing where they meet the flat roof is rebuilt.

On a shared roof, the schedule matters as much as the coating. This is the order we follow.

We walk the full roof, note each tenant's unit and curb, check every lap, and take moisture readings where stains show inside.
A roof-section calendar goes to you to share with tenants, with quiet hours set near salons, clinics, and offices.
Screws, laps, curbs, and gutters are fixed one tenant section at a time so each space is affected only briefly.
Each section is washed, primed, detailed, and coated before the crew moves to the next.
A closing walk checks thickness and drains, and you get photos of every section for your records.
Our coverage includes these towns as well. Not on the list? Call us or send us a message.
Commercial roofs booked around the late-spring-to-fall coating season.
Waterloo metal roof coatingQuestions property managers in Ralston ask most.
Yes, almost always. All work is on the roof surface, so storefronts keep operating. We stage away from entrances and work around each tenant's rooftop unit.
Roof size, the number of tenant curbs, lap and screw repairs, and gutter work. Coating plans at about $2.50 to $4.00 per square foot, and section-by-section scheduling adds little to the total.
Single-tenant buildings get coated as well as full rows. Smaller roofs get the same inspection, repair list, and coating sequence.
Much quieter than a tear-off. Most of the work is washing, rolling, and spraying, with short bursts of screw work at each lap.
A written schedule comes from us for you to share, with dates, roof sections, and quiet hours. Many owners forward it to tenants as is.
Section-by-section pricing works when leases split roof costs. We measure each tenant's section on the roof walk and list its screws, laps, curbs, and area, so the total breaks down by space.
Grease from kitchen exhaust breaks down coatings around the fan. That area gets a grease-resistant detail and a pad or box under the fan, and we set the hood shutdown with the tenant.
Usually nothing. Work stays on top of the roof. Tenants with stock right under a known leak can cover it until that lap is sealed, and we tell them which areas those are.
Send the address and tenant count, and we schedule a roof walk that works around your storefronts.
