Chicago Commercial Roof Repair: Fixing Soft, Rotten Substrate Damage

f you've noticed soft, spongy, or sagging areas on your commercial flat roof in Chicago, you are likely dealing with rotten or damaged substrate. The substrate, or roof deck, is the structural foundation of your roof system, and when water penetrates the membrane, it saturates and destroys this essential material.

Ignoring damaged substrate leads to serious consequences for your commercial property:

Structural Failure: A rotten deck compromises the load-bearing capacity of your roof, posing a safety risk, especially under snow loads or heavy equipment.

Widespread Leaks: The damaged structure creates dips where water pools, eventually finding new entry points.

Compromised Insulation: The insulation beneath the membrane gets wet, losing its thermal resistance and driving up your energy costs.

At Anchor Point Roofing, we specialize in comprehensive commercial roofing solutions and lasting Chicago roof repair. We don't just patch the surface; we fix the structural root of the problem.

Our Expert Process for Fixing Damaged Substrate:

Detailed Assessment: We meticulously locate and mark all areas affected by soft or rotten substrate damage.

Removal of Damaged Materials: We carefully remove the existing roofing materials (membrane and insulation) and then completely remove the damaged substrate.

Installation of New Substrate: We install a new, sturdy roof deck substrate to restore the structural integrity and provide a sound foundation for the rest of your roof system.

Insulation Replacement: We install new insulation as needed to replace any material that was water-damaged, ensuring maximum thermal efficiency.

New Membrane System: We install a new base sheet followed by a durable modified bitumen membrane. This system provides multiple layers of protection against water intrusion.

Protective Coating: Finally, we touch up the surface with a reflective aluminum coating (for smooth modified bitumen). This coating reflects harmful UV rays, helping to regulate your roof temperature and extending the lifespan of your repair.

Don't let damaged substrate threaten the stability of your commercial building. Contact Anchor Point Roofing today for reliable Chicago commercial roof repair and a solution that restores the strength and watertight integrity of your roof.
