Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Donnellson Roofing & Maintenance has the training and equipment to handle all of it across Donnellson.
Our Commercial Roofing Process
Building Inspection
Our inspector walks your commercial roof and documents every issue: ponding areas, seam failures, flashing deterioration, clogged drains, and UV damage. Photos and measurements provided in a report you can share with your property manager or ownership.
Detailed Proposal
Your proposal includes material specifications, installation method, warranty terms, project timeline, and total cost. We itemize everything and explain why we're recommending the specific system for your building.
Expert Crew
Our commercial crew installs per manufacturer specifications and NRCA guidelines. Hot-air welded TPO seams tested with a probe at every joint. Flashing details custom-fabricated for your building's penetrations. Insulation installed to achieve minimum R-value per code.
Final Inspection
Manufacturer warranty registered upon completion, 15-20 year coverage depending on system and build-up. We offer maintenance contracts to keep your warranty valid and your roof performing for its full life span.
