Rooftop Units Over Restaurants

- What It Means
- Kitchen exhaust softens some coatings. Those areas get cleaned, primed, and coated with a product rated for that exposure.
Mount Lebanon metal roof coating starts by planning the work zone below. Then we coat the roof in sections around shoppers, diners, and tenants.



Mount Lebanon metal roof coating often happens over open businesses, with outdoor seating, sidewalks, and entrances right below the roof edge. We check wind exposure, access, and where people and equipment sit before choosing between rolling and spraying.
Some sections get a different order of work or a temporary barrier so roof prep never spills onto the activity below.
Storefront and office roofs here wear in a few familiar ways. Each card shows what drives the problem and what it means before coating.
Failures we often find on Mount Lebanon storefront roofs, paired with what the coating work does.
Lap leaks drip onto display areas and ceilings below.
Laps are sealed and bridged so the coating covers them in one surface.
Offices over storefronts heat up under dark roofs in summer.
A light topcoat reflects more sun and keeps the roof surface cooler.
Wind lifts panels and trim along exposed roof edges.
Edge fasteners and trim are reset before coating locks them in.
Standing meltwater rusts the low edge of the roof first.
Rust is treated and primed, and the edge gets an extra coat.
Coating choices for Mount Lebanon buildings follow the roof type and how close the work sits to people.
| Option | Where It Fits | What To Know |
|---|---|---|
| Rolled acrylic | Sloped metal over storefronts | Little drift near outdoor seating |
| Silicone on low-slope sections | Flat roofs behind parapets | Handles slow-draining corners |
| Shingle coating on mansards | Office fronts with shingle faces | Only where both makers approve |
| Spot repairs and walk pads | Roofs mostly in good shape | Fixes service paths and laps |

How a roof over an open business gets coated, step by step.
We walk the roof, check laps, caps, gutters, and rooftop units, and note what sits below each edge: seating, entrances, or parking.
Each roof section gets a time window agreed with the tenants under it, with deliveries and peak hours left clear.
Loose edge trim, failed parapet caps, and open laps are fixed before any prep reaches the field.
Washing and rust primer go on section by section, with runoff kept off sidewalks and doorways.
Coating is rolled near occupied areas and finished one zone at a time so each tenant has a short window.
Besides Mount Lebanon, we coat commercial roofs in the towns below. For anywhere else, call us or send us a message.
River terminals, fabrication shops, and hillside blocks with metal roofs.
Church, school, and office roofs checked from below.
Fabrication shops with old vent bases to rebuild.
Commercial roofs with worn rooftop service paths.
Warehouse roofs crossed by cable runs and supports.
Yes, when the application and protection can be controlled. We check wind exposure, access, and how close people and equipment sit before picking a method. Some sections are done in a different order or behind a temporary barrier so roof prep stays clear of the tables and sidewalk below.
Coating falls in a range of about $2.50 to $4.00 per square foot of roof, and replacement about $5 to $8. On storefront blocks, staging around tenants, parapet and gutter repairs, and the number of rooftop units often move a roof within that range more than its size does.
Restaurants, shops, offices, and mixed-use buildings make up most of the roofs we coat in Mount Lebanon. The work is scheduled around each tenant, and we keep materials and equipment off public walkways as much as the lot allows.
Call us with the address, and we will set up a roof walk at your building. We cover Mount Lebanon and the nearby towns listed here, and we can tell you right away whether your roof falls inside that area.
Most roofs here are coated with the businesses open. Quiet hours, delivery times, and entrance areas are agreed before work starts, and the noisiest prep is scheduled outside opening hours where tenants ask for it.
Near storefronts we roll instead of spraying, mask awnings, signs, and HVAC intakes, and keep a ground person watching the sidewalk while prep and coating are underway. Spray work, where it is used at all, is kept to calm days and sections well back from the edge.
Signs usually stay up. We seal and coat around the sign supports, and where a base sits in a puddle or has rusted, the support gets flashed so water runs past it. Any sign that must be loosened is handled with the owner and the sign company first.
