Loose Wall Flashing on Your Chicago Commercial Roof? Causing Leaks
June 6, 2025

Is your Chicago commercial building experiencing mysterious leaks, especially along the interior of exterior walls or where your flat roof meets a vertical structure like a parapet wall? The culprit is very often loose wall flashing. Wall flashing is a critical component of your commercial flat roofing system, designed to create a watertight seal at these vulnerable junctures.
When wall flashing becomes loose, detaches, cracks, or deteriorates, it creates direct entry points for water. This can lead to:
Interior Water Damage: Leaks can manifest as stained ceilings, damaged drywall, ruined inventory, or compromised electrical systems.
Insulation Degradation: Water infiltration can saturate the insulation within your walls and roof, reducing its thermal performance and potentially leading to mold growth.
Structural Weakening: Persistent moisture can cause rot in wood framing or corrosion in metal components, compromising the structural integrity of your building.
Accelerated Roof Deterioration: Unaddressed flashing issues can hasten the overall breakdown of your commercial roof system, leading to more extensive and costly repairs down the line.
At Anchor Point Roofing, we specialize in expert commercial roof repairs in Chicago, understanding the unique challenges and critical importance of proper flashing on flat roofs. When you contact us about leaks due to loose wall flashing:
Our experienced team will conduct a thorough inspection to assess the condition of all wall flashing, identify the exact points of failure, and determine the extent of any underlying damage.
If coping stones are present, we will carefully remove and save the coping (the cap on top of the parapet wall) to access the flashing beneath.
We will then remove the loose or damaged wall flashing to prepare the area for a secure, long-lasting repair.
Next, we meticulously prep the underlying surface, ensuring it is clean, dry, and ready for optimal adhesion.
We will install new membrane that matches your existing commercial roofing system, whether it's a durable TPO (Thermoplastic Polyolefin) membrane, a robust granulated membrane, or a smooth modified bitumen membrane. This ensures a seamless and watertight tie-in with your existing roof.
For smooth modified bitumen membrane installations, we will apply a protective aluminum coating to enhance durability and UV resistance.
