Why is My Commercial Flat Roof Membrane Open in Chicago? Causing Leaks

Discovering leaks in your Chicago commercial building, especially when you have a flat roof, often points directly to openings in the roof membrane. These aren't always obvious punctures. More commonly, you'll find issues like:

Open seams: Where sections of the membrane have pulled apart due to thermal expansion and contraction, adhesive failure, or age.

Blisters and delaminations: Air or moisture trapped beneath the membrane causing bubbles that can eventually rupture.

Cracks and tears: From weathering, impact damage, or structural movement.

Any of these openings allow water to infiltrate your roof system, leading to significant problems for your business. This includes interior water damage, saturated insulation (which ruins its efficiency), and potential structural damage to your building's deck. Ignoring these issues will inevitably lead to more extensive and costly commercial roof repairs down the line.

At Anchor Point Roofing, we specialize in expert commercial roofing services and Chicago roof repair. We understand the critical role your flat roof plays in protecting your business assets. When you contact us about membrane openings:

Our experienced team will conduct a thorough inspection to accurately identify all compromised areas and the underlying causes of the membrane failure.

We will then meticulously remove the damaged or open membrane sections. This ensures we're working with a clean, sound surface for the repair.

Finally, we will install new membrane that seamlessly matches your existing flat roof system. Whether your roof is a durable TPO (Thermoplastic Polyolefin) membrane, a robust granulated membrane, or a smooth modified bitumen membrane, we ensure a precise, watertight installation. For smooth modified bitumen, we also apply a protective aluminum coating for enhanced durability and UV resistance.
