Are My Old Skylights on My Shingle Roof Causing Leaks?

Old skylights on a shingle roof are one of the most common sources of hidden water leaks in a home. Over time, the seal around the skylight can weaken, flashing can deteriorate, and the skylight unit itself may become brittle or cracked due to weather exposure. Even if the shingles around it still look fine, water can still find its way in through small gaps around the skylight frame or curb.

Homeowners often notice signs like water stains on the ceiling, peeling paint around the skylight, or damp spots after heavy rain. In many cases, the issue isn’t the entire roof—it’s the aging skylight that no longer provides a watertight seal.

At Anchor Point Roofing Chicago, we often see these types of issues during roof inspections. That’s why we recommend high-quality replacement options like Velux Skylights, which are known for their durability, energy efficiency, and superior leak protection. Velux skylights are engineered with advanced flashing systems designed to integrate properly with shingle roofs, helping to prevent the common leak problems associated with older skylight units.

Replacing or upgrading an old skylight can significantly improve both the protection and comfort of your home. It also helps ensure your roofing system works as one complete, sealed structure rather than a weak point that can lead to costly interior damage.

If your skylights are older or showing signs of leaking, it may be a good time to have them inspected before the issue gets worse.
