Repair the defined failure
A sound roof with a damaged seam, puncture or flashing can be a repair. Compatible materials and the surrounding system condition control how it is tied in.

Commercial roof repair, restoration and replacement decisions for Nichols Hills building owners and property managers.
A leak beside a rooftop unit can come from the curb flashing, a nearby seam or another opening uphill. The inspection follows the water path and examines the roof around it. Repeated patching at an interior leak location does not establish where the roof failed.
The next question is what lies below the surface. Suspected wet insulation and damaged deck areas need investigation to establish their extent. A dry-looking membrane alone is not enough to approve restoration or a new covering over an existing assembly.

The goal is a sound roof and an agreed plan for the building. The viable work depends on the existing membrane, support, moisture and drainage.

Explore Commercial Roof RepairA coating system starts with a compatible roof that can be prepared properly. Wet insulation, unstable support and unresolved drainage must be corrected first.
Explore Roof CoatingsWidespread deterioration, moisture and unsuitable support can move the decision toward removal and replacement. Drainage and insulation are part of the new system design.

| System | How it is joined | Where the assessment concentrates |
|---|---|---|
| TPO | Thermoplastic sheets with heat-welded seams. | Seams, perimeter attachment, equipment curbs and compatible repair material. Read about TPO roofing. |
| EPDM | Rubber membrane with system-specific taped or adhesive seam details. | Splices, penetrations, shrinkage or stressed flashing, and substrate condition. Read about EPDM roofing. |
| Modified bitumen | Reinforced asphalt sheets installed as a specified assembly. | Laps, surface wear, flashing transitions and moisture below the roof. Read about modified bitumen. |
Roof access, rooftop equipment and the activity beneath the project influence the work sequence. Tell us about occupied rooms, sensitive equipment, customer entrances, deliveries and any access restrictions. These details help establish workable staging and protection with the contractor.
HVAC, electrical and roof work sometimes meet at the same penetration. Trade coordination needs a clear owner so a completed roof detail is not opened again without a plan. Adhesives and installation conditions also depend on the selected system.
Current symptoms and earlier repairs help direct the assessment without predetermining the cause.
Access points, curbs, service paths and rooftop units affect safe work and sequencing.
Occupancy and business activity belong in the agreed schedule; no blanket downtime promise fits every roof.
A commercial budget depends on more than membrane square footage. Existing layers, removal, insulation moisture, deck repairs, drainage and perimeter details shape the project. The required attachment and insulation plan must fit the building and the selected system.
Our residential shingle calculator does not price commercial systems. Tell us the building use and known roof type so the discussion starts with the right assembly and a property-specific scope.

A coating can restore an eligible existing roof after compatible preparation and repairs. It does not replace wet insulation or damaged decking, and it does not solve poor drainage by itself.
Tell us the property location, building use, leak areas and known roof system. Existing roof records and access instructions are helpful when readily available. You do not need to investigate the roof yourself.
Yes. Request a free inspection and describe the building and concern so roof access and the next step can be discussed.
Tell us what the roof protects and where the problem is affecting the building.
