Leaks and targeted repairs
Investigate openings at seams, flashing, drains, edges, and rooftop equipment. A repair plan should address the water-entry point and any affected materials—not simply cover the interior stain.
Commercial roof repairRoof replacement planning
Evaluate recurring failures, wet materials, deck condition, drainage, and the existing assembly before selecting a replacement approach. Compare clearly defined scopes and alternates.

Document current conditions, prioritize repairs, and establish a record for future budgeting. Regular attention to drainage and vulnerable details is more useful than waiting for the next leak.
Commercial roof inspections · MaintenanceWhat a useful commercial roof assessment should include
- Building history: roof age when known, previous repair locations, leak timing, warranties, and available roof plans.
- Interior observations: locations of reported leaks and whether they occur during rain, snowmelt, or other conditions.
- Accessible roof details: membrane condition, seams, penetrations, edge metal, flashing, drains, and scuppers.
- Limitations and further testing: identify concealed conditions that a visual inspection cannot establish. Discuss any separately scoped moisture testing or investigative openings before proceeding.
- Documented next steps: distinguish immediate repairs, further investigation, maintenance, and replacement planning.
For repeated or difficult-to-locate leaks, review our commercial leak investigation service. An inspection is not a guarantee that every concealed condition can be identified without opening the roof.
Roof systems: match the material to the assembly
TPO and PVC membranes
These thermoplastic systems use heat-welded seam details. Material identification, weld preparation, attachment, insulation, and drainage all matter. Specify the actual manufacturer, membrane thickness, and installation requirements instead of comparing membrane names alone.
EPDM rubber roofing
EPDM requires compatible repair materials and seam or flashing details for the existing system. A proposed repair should identify the membrane and address substrate condition, surface preparation, and any underlying moisture concerns.
Existing roofs and coatings
A coating is not a substitute for evaluating leaks, trapped moisture, drainage, or a deteriorated roof deck. Confirm that the existing system and its condition are suitable before choosing restoration rather than replacement.
Commercial and multifamily projects need a site plan
Roof work affects more than the roof surface. For apartments, offices, and occupied commercial buildings, discuss entrances, tenant notices, delivery routes, parking, rooftop equipment, and the working hours the property can accommodate.
For bid requests, send the drawings, specifications, addenda, project address, bid deadline, anticipated construction dates, and required bid form. Identify required alternates, phasing, insurance, warranties, and any project labor requirements so the proposal can respond to the actual scope.
Sellers Roofing is a Black-owned union roofing company. Request current business credentials, insurance documentation, and project-specific qualifications before award.
Compare commercial roofing estimates by scope
A square-foot price is not useful unless the assemblies and exclusions match. Ask each bidder to identify:
- Measured roof area, removal layers, disposal, access, and staging.
- Insulation, cover board, membrane, attachment, flashing, and drainage work.
- Deck repairs and concealed damage: included quantities, allowances, and approval procedures.
- Permits, inspections, equipment coordination, and protection of occupied areas.
- Workmanship coverage, manufacturer warranty options, exclusions, and closeout documents.
Weather, material availability, roof access, phasing, and concealed conditions affect both cost and schedule. The written proposal should state its assumptions rather than promise the same price or completion window for every building.

Commercial roofing questions
Does an active leak mean the entire roof needs replacement?
Not necessarily. A localized defect may be repairable when the surrounding assembly remains serviceable. Recurring leaks, widespread deterioration, moisture below the surface, and drainage problems may require a broader evaluation. The condition of the assembly—not a leak alone—should guide the recommendation.
Can roofing work be phased around tenants or business operations?
Phasing and access requirements should be discussed during estimating. Tell us about delivery restrictions, tenant entrances, noise-sensitive periods, and equipment that must remain operational. Any special working hours or temporary protection should be included in the agreed scope.
Can you provide storm-damage documentation?
We can discuss inspection photographs and a roofing repair or replacement scope for your records. Coverage and claim-payment decisions remain with the insurer under the policy; a contractor inspection does not establish coverage or guarantee payment.
How do I request an estimate?
Send the property address, building type, roof information you have, a description of the problem, and your preferred contact method. Property managers and general contractors can request a project consultation and arrange how to share plans and bid requirements.
