Does My Flat Roof in Chicago Need Vents? What Happens If It Doesn’t?

If you’re dealing with leaks, trapped moisture, or bubbling on your flat roof in Chicago, it might not just be the roofing material that’s the issue — it could be poor or missing ventilation.

At Anchor Point Roofing, we’ve inspected countless low-slope and flat roofs throughout the city, and one of the most common issues we find is a lack of proper roof ventilation. Without vents, heat and moisture can build up beneath the roofing system, leading to premature wear, blistering, mold, and even interior water damage.

What We Do to Fix It

If your flat roof is missing vents, don’t worry — we can help. Our team will:

Install new vents designed for low-slope roofing systems to help regulate temperature and moisture.

Replace damaged membrane roofing with a new membrane that matches your existing system, whether it's TPO or modified bitumen.

For modified bitumen roofs, we can also apply an aluminum coating to help protect and extend the life of the material.

We’ll also perform targeted roof repairs as needed to make sure the system is watertight and functioning properly.

Whether you need a few quick repairs or a more thorough solution, Anchor Point Roofing is here to help. We’re proud to serve Chicago building owners and property managers with honest assessments, clear recommendations, and quality work.
