Your commercial roof is protecting your inventory, your equipment, your employees, and your revenue. A leak doesn't just damage the building. It shuts down operations. Donovan Roofing & Maintenance provides commercial roofing services that keep Donovan businesses covered and dry.
Our Commercial Roofing Process
Commercial Roof Assessment
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
We present options when they exist: repair vs. replace, TPO vs. PVC, 15-year vs. 20-year warranty. Each option is priced so you can make an informed decision based on your budget and building plans.
Expert Crew
Installation phased to minimize disruption to your tenants and business operations. Debris containment, noise management, and clean work areas maintained throughout the project. Project manager on-site for every commercial installation.
Warranty Activation
Final roof inspection with photo documentation. Warranty paperwork provided. We recommend an annual maintenance plan to catch issues early and maintain warranty compliance.

About Our Donovan Commercial Roofing Services
Ponding water is the number one cause of commercial roof failure. Water that doesn't drain within 48 hours degrades the membrane and insulation underneath. Donovan Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
Call (877) 349-1553 for a free commercial roof assessment. We inspect the membrane, flashings, drainage, penetrations, and overall condition. You get a written report with photos and our honest recommendation, repair, coat, or replace.
