Leak Near Skylight in Chicago Flat Roof: What's Wrong?

If you've noticed water leaking around the skylight on your Chicago flat roof, you're not alone. Skylights, while adding natural light and ventilation, can be common sources of leaks on flat roofs, especially if they weren't installed perfectly or if the seals and flashing have deteriorated over time. The flat nature of the roof can also exacerbate this issue, as water tends to pond, increasing the chance of finding any weakness in the skylight installation.

One common reason for leaks around flat roof skylights is openings or gaps in the sealant or flashing where the skylight meets the roof membrane. Additionally, if there isn't proper drainage around the skylight, water can pool and eventually find its way through even seemingly small imperfections.

Here at Anchor Point Roofing, we understand the nuances of flat roof repair in Chicago, including the specific challenges posed by skylights. Our approach to fixing leaks around skylights includes:

Thoroughly inspecting the area to pinpoint the exact source of the leak and assess the condition of the existing skylight, flashing, and membrane.

Installing new tapered insulation or a plywood assembly to create a cricket on the downhill side of the skylight. A cricket is a sloped structure designed to divert water away from the skylight and prevent ponding.

Installing new membrane that seamlessly matches your existing flat roof system, whether it's durable TPO (Thermoplastic Polyolefin) or robust modified bitumen membrane. Our goal is to create a watertight seal around the skylight.

Applying aluminum coating to the repaired area if your existing membrane is modified bitumen. This provides an extra layer of UV protection and extends the lifespan of the repair.
