We recently completed a long-term repair for a customer experiencing persistent issues at a transition between two roof levels. The upper roof, covered with an EPDM rubber membrane, wraps down onto a lower metal roof, creating complex termination points that had seen multiple temporary fixes over the years.

Spring and summer are the ideal time to address your commercial roofing needs before small issues become major problems.

Cotterman & Company Inc.'s QTS NAL1 DC1 (Data Center) project in New Albany, Ohio was recognized as the Low Slope New Construction Sika Project of the Year by Sika Roofing & Waterproofing.

Preventative Maintenance: Address small issues now. Roof Replacement Planning: Budget for a replacement. Lock in pricing: Secure today's rates. Priority Scheduling: We still have room for your project this spring or summer!

Last week, after the snow and ice finally cleared here in Dayton, Cotterman & Company Inc. completed a roof evaluation on a large warehouse facility that had recently started experiencing leaks. As part of the inspection, a date stamp was located on the membrane: DL ’99. That simple marking told a big story.

After severe storms rolled through the area, our Service Department was called to a local hospital to investigate new roof leaks. Cotterman & Company responded quickly and delivered solutions that protected critical facilities with no shutdowns, no delays, and no compromises.

We want to take this opportunity to thank our valued customers for a wonderful year. Your trust and support have been the foundation of our success, and we’re truly grateful. We look forward to continuing to serve you with high-quality roofing solutions in 2026 and beyond!
