Commercial Flat Roofing Services in Wellesley
Commercial roofing projects can range from a localized membrane repair to a complete roof replacement. The appropriate scope depends on the existing roofing system, leak history, drainage, insulation, roof deck condition, penetrations, rooftop equipment, access, and the overall condition of the roof.
Commercial Roof Repair
Repair work may address membrane damage, open seams, flashing, penetrations, drains, roof edges, rooftop equipment, or previously repaired areas.
Flat Roof Replacement
When localized repairs are no longer practical, we can evaluate partial or complete replacement based on the existing assembly and project requirements.
Inspection & Maintenance
Roof inspections and maintenance planning can help property managers document current conditions, drainage issues, previous repairs, and areas requiring attention.

Commercial Roofing Systems We Work With
Different roofing systems require different installation and repair methods. Identifying the existing membrane and roof assembly is an important part of planning the work.
PVC Roofing
PVC is a thermoplastic single-ply roofing membrane commonly used on commercial and low-slope buildings. Repairs and installation details may involve heat-welded seams, flashing, drains, penetrations, and roof edges.
TPO Roofing
TPO is another thermoplastic membrane system. Its condition should be evaluated at seams, flashing, penetrations, drainage components, rooftop equipment, and damaged membrane areas.
EPDM and Rubber Roofing
EPDM is a synthetic rubber membrane. Common repair considerations may include seams, punctures, flashing, shrinkage, penetrations, drains, and previous patch locations.
Modified Bitumen
Modified bitumen roofs may require evaluation of seams, flashing, cracks, blisters, surface deterioration, penetrations, drainage, and moisture within the roof assembly.
Built-Up Roofing
Built-up roofing systems consist of multiple roofing layers. Repair or replacement planning may require evaluation of the surface, underlying layers, insulation, flashing, drainage, and roof deck.

What We Evaluate on a Commercial Flat Roof
A commercial roof should be evaluated as a complete system rather than by looking only at the location of a visible leak.
- roof membrane condition
- seams and previous repair areas
- flashing at walls, curbs, and roof edges
- drains, scuppers, and other drainage components
- pipes, vents, and penetrations
- HVAC curbs and rooftop equipment
- punctures or physical membrane damage
- areas of recurring ponding water
- possible wet insulation or damaged roof decking
- roof access and project logistics

Commercial Roof Repair or Replacement?
Not every leak requires a roof replacement. A localized repair may be appropriate when the source of water entry can be identified and the surrounding roofing system remains serviceable.
A larger repair or replacement project may need to be considered when deterioration affects multiple areas, previous repairs repeatedly fail, insulation is wet across a larger section, drainage requires broader correction, or the existing roof can no longer support practical localized repairs.
The recommendation should follow inspection of the actual roof conditions rather than being based on roof age alone.
Commercial Roof Maintenance & Planning
Commercial roof maintenance can include inspection of membrane condition, seams, flashing, penetrations, drains, rooftop equipment, previous repair areas, and drainage conditions.
Keeping photographs, repair records, roof plans, warranty documents, and information about rooftop equipment changes can also make future roof management and leak investigation easier.
See our Commercial Roof Maintenance Guide for more information.

Active Commercial Roof Leak in Wellesley?
An active leak affecting occupied spaces, equipment, inventory, ceilings, insulation, or other interior materials may require urgent attention.
Emergency work may initially focus on locating the source of water entry, controlling the leak, or stabilizing the affected area. Permanent repair can follow once roof and weather conditions allow the complete scope to be evaluated.
For an active commercial roof leak, visit our Commercial Emergency Roof Repair page or call +1 (617) 299-0291.
