Soft Areas on Chicago Commercial Flat Roof? Urgent Substrate Repair

Noticing soft, spongy, or even sagging areas on your commercial flat roof in Chicago? This isn't just a minor issue; it's a critical warning sign of damaged substrate beneath your roofing membrane. The substrate, typically plywood or insulation board, forms the essential foundation for your entire roof system. When it becomes compromised by moisture intrusion, it loses its structural integrity, leading to:

Compromised Structural Support: A weakened substrate can't adequately support the weight of the roof membrane, equipment, and snow loads, potentially leading to dangerous structural failure.

Persistent Leaks: Even if the membrane appears intact, soft substrate beneath it means water has already infiltrated, and more significant leaks are likely imminent or ongoing.

Reduced Insulation Effectiveness: Saturated insulation within the substrate greatly diminishes your building's energy efficiency, leading to higher utility bills.

Accelerated Roof Deterioration: Ignoring damaged substrate will significantly shorten the lifespan of your entire commercial roofing system, making a full replacement inevitable much sooner.

At Anchor Point Roofing, we specialize in comprehensive commercial roof repair in Chicago, understanding the unique demands of flat roofing systems for businesses and properties. Our expert team will conduct a thorough inspection to accurately diagnose the extent of the substrate damage and identify the source of the moisture.

Our process for addressing compromised commercial flat roof substrate typically includes:

Precise Isolation: We carefully delineate the areas of damaged substrate.

Strategic Removal: The compromised sections of the existing membrane and insulation are systematically removed.

Substrate Replacement: We remove the rotten or weakened substrate and install new, sound decking material, ensuring a solid, stable foundation for your roof. This often involves new plywood or specialized insulation boards, depending on your roof's original construction.

New Membrane Installation: We then install new roofing membrane, precisely matching your existing system (such as modified bitumen, TPO, or PVC), ensuring a seamless and watertight seal over the newly repaired substrate.
