Commercial Roof Repair and Flashing Work in Skokie

A lot of commercial roof leaks don't start in the middle of the roof. They start at the edges and around equipment. Wall flashing that's pulled away from the brick, A/C curbs that were never properly sealed - that's where water finds its way in. And once it does, it doesn't stop on its own.

On this Skokie building, that's exactly what we were dealing with. We installed new modified wall flashing along the parapet, sealed around the A/C curbs, and then coated the repaired areas with aluminum roof coating. Each of those steps matters. The modified flashing creates a tight, durable barrier where the roof meets the wall. The sealant around the curbs closes off the gaps that equipment installation often leaves behind. The aluminum coating ties it all together and adds a reflective layer of protection on top.

This is what commercial roof repair and maintenance actually looks like when it's done right. It's not glamorous work, but skipping any one of these steps is how a small problem turns into a big one. Water intrusion in a commercial building is expensive - it damages inventory, disrupts operations, and can compromise structural elements over time.

Preventive maintenance on a flat roof is one of the best investments a building owner can make. Catching failing flashing or unsealed penetrations before they become leaks keeps repair costs manageable and extends the life of the roof significantly. We work on commercial and industrial flat roofs throughout the Skokie area and beyond, and this kind of targeted repair is something we do routinely.
