Rooftop Units
Each tenant space has its own unit, and each unit has four flashed corners. A split corner drips straight into a suite below.

As a Munster commercial roof repair contractor, we repair flat roofs on offices, medical buildings, and retail centers while the businesses below stay open.

Munster commercial roof repair usually happens over people at work. We plan noise, access, and staging around the tenants before going up.
Ladders and material go up at a side or rear wall, away from front doors and patient parking. Loud steps such as cutting out wet board are booked for hours you choose, and each repair area is closed before we leave.
Office and retail roofs here carry rooftop units over busy spaces. These five spots cause most of the calls.
Each tenant space has its own unit, and each unit has four flashed corners. A split corner drips straight into a suite below.
Single-ply laps open at corners and T-joints, often over hallways where the stain shows on a ceiling tile.
Retail and office roofs drain to bowls inside the building. A loose clamp ring leaks right above a storefront or exam room.
Short parapets around storefront roofs carry base flashing that pulls away, letting water run inside the front wall.
Technicians servicing rooftop units drop tools and screws. Small punctures near the units let water in slowly for months.
In an occupied building, a repair changes what tenants notice as much as the roof. These are the before and after.
Munster buildings call for different repairs depending on the roof and the tenants. These four cover them.

Most Munster offices and retail centers have single-ply flat roofs. Repairs focus on seams, interior drains, and the flashing at short parapets.

Some retail and service buildings here have metal canopies or metal roofs over back-of-house areas. Those panels get fastener and lap repairs.

A stain in one suite can start over the suite next door. A careful trace keeps us from opening roof above the wrong tenant.

Light industrial and flex buildings carry heavier equipment than offices. Industrial repairs handle their curbs, fans, and drains.

You pick the hours for loud work, and we note which tenants need notice and which entrances stay clear.
Ladders, material, and the truck go to a side or rear wall, away from storefronts and patient parking.
The leak is traced from the stained tile up, then the seam, curb, or drain behind it is repaired and tested.
Each repair area is sealed and the roof is cleared of scraps before we leave, with photos sent that week.

Offices, retail buildings, and professional buildings in Munster are a large share of our flat roof work. Typical repairs are resealing seams, fixing flashing at rooftop units, clearing drains, and patching blisters or punctures, with businesses staying open below and each area closed before we leave.
Call with the building address, the suite where water shows, and the hours tenants are in. We repair flat and metal roofs across Munster and plan the visit around the people below.
Expect questions about tenants, entrances, and quiet hours before the roof itself. A contractor working over occupied space should also carry insurance and send photos of the problem and the finished repair.
Cost depends on the roof type, the size of the damaged area, how much wet insulation comes out, and how the roof is reached. Work booked outside normal hours to protect tenants adds labor time, and that shows in the estimate.
Most repairs never touch the space below. Ladders go up away from entrances, loud steps are booked for quiet hours, and the only interior work is checking ceiling tiles under the leak with your permission.
Send the address, the suite with the leak, and the hours that suit your tenants. We walk the roof and price the repair.
