You’ve just replaced your roof—and then it happens. A few months later, you notice a water stain on the ceiling and think, “How can my brand new roof be leaking already?”
Here’s the truth: it’s probably not your roof.
Chimneys: A Common Source of Roof Leaks
Chimneys are one of the most common—and most overlooked—sources of roof leaks. Because they sit above the roofline and endure constant exposure to the elements, small cracks or gaps in the chimney’s masonry or flashing can allow water to seep in. Over time, that moisture makes its way inside, often giving homeowners the impression that their roof has failed when the real culprit is the chimney itself.
Why It Happens
In Northern New Jersey, we experience heavy snow, ice dams, and repeated freeze–thaw cycles every winter. These conditions expand even the tiniest openings around a chimney, allowing water to penetrate. Left unchecked, this can cause interior leaks, damaged ceilings, and even rot around roof framing.
Our Approach: Chimney Inspection and Waterproofing
At George J. Keller & Sons, we include a chimney inspection as part of every roof consultation. During your initial visit, our project consultants carefully examine both your roof and your chimney so nothing is overlooked. Our consultants will photograph any issues they see to share with you.
We typically recommend addressing chimney repairs before your roof replacement—this ensures both systems work together properly and your new roof remains watertight for years to come.
Our dedicated chimney waterproofing and repair division handles this work seamlessly as part of your overall project—making us your one-stop shop for complete exterior protection.
What’s Included in Chimney Waterproofing
- Crown (Top) Sealing: The top surface, or crown, is sealed with a high-grade silicone waterproofing product to prevent water infiltration.
- Face (Side) Sealing: The vertical brick or stone surfaces are inspected and treated with breathable silicone sealant to block moisture while allowing vapor to escape.
- Flue Cap Replacement: If your flue cap is damaged, missing, or rusted, we can replace it to ensure proper coverage and ventilation.
These steps work together to create a barrier that protects your chimney from the elements—and protects your home from costly leaks.
Your roof and chimney may be separate systems, but they function as one when it comes to protecting your home. A roof is only as watertight as the structures that penetrate it, and keeping your chimney properly maintained is essential to keeping your roof leak-free.
