Chimney Flashing
Chimney Flashing in Raleigh, NC
Your chimney is one of the most leak-prone areas of any roof. Where masonry meets roofing, a watertight seal is essential — and that seal is chimney flashing. At Simple Construction Roofing, we specialize in chimney flashing repair and replacement for homeowners across Raleigh, NC. Whether your flashing has rusted through, pulled away from the brick, or was never installed correctly in the first place, our certified crew will rebuild a watertight seal that protects your home for decades to come.
What Is Chimney Flashing?
Chimney flashing is the metal barrier that seals the joint where your chimney passes through the roof. A proper chimney flashing system has two parts working together: step flashing and counter flashing. Step flashing consists of small L-shaped metal pieces woven into each course of shingles along the sides of the chimney, directing water down and safely off the roof. Counter flashing — also called cap flashing — is embedded directly into the chimney’s mortar joints and folds down over the step flashing, so water running down the brickwork is thrown clear of the joint instead of seeping behind it. Quality flashing is typically fabricated from aluminum, galvanized steel, or long-life copper, and when it is installed correctly, it lasts as long as the roof itself.
Signs Your Chimney Flashing Is Failing
Because flashing sits at the intersection of two very different materials, it takes a beating from North Carolina’s freeze-thaw cycles, driving rain, and summer heat. Call us for a free inspection if you notice any of these warning signs:
- Water leaking around the chimney or fireplace, especially after heavy rain
- Rusted, bent, or visibly damaged flashing along the base of the chimney
- Water stains on ceilings or walls near the fireplace
- Cracked or missing caulk and sealant where the flashing meets the brick
- Loose or missing shingles around the chimney
- A musty smell or mold growth in the attic near the chimney chase
Flashing leaks only get worse with time. Water intrusion can rot roof decking, ruin ceilings and drywall, and invite mold — turning a simple flashing repair into a major restoration.



Our Chimney Flashing Repair and Replacement Process
Every chimney flashing project starts with a free, thorough inspection. We examine the existing flashing, the surrounding shingles, the mortar joints, and the attic side of the chimney for hidden water damage. Then we get to work:
- Remove the old flashing. We carefully take out the failed flashing and any damaged shingles around the chimney, protecting the surrounding roof.
- Install new step flashing. Each L-shaped piece is woven with the shingle courses so water is channeled safely down the roof plane.
- Set new counter flashing. We cut into the mortar joints, embed the counter flashing, and fold it down over the step flashing for a double layer of protection.
- Seal it watertight. Every joint is sealed with premium, UV-stable sealants for a clean, watertight finish.
- Test and clean up. We water-test our work, photograph the finished flashing for your records, and leave your property spotless.
Most chimney flashing replacements are completed in a single day, and you will barely know we were there — except the leaks stop.

Chimney Flashing FAQs
How much does chimney flashing repair cost in Raleigh?
Every chimney is different, but flashing repairs are very affordable compared to the water damage they prevent. We provide free inspections and upfront pricing before any work begins, so you will always know the cost in advance.
How long does chimney flashing last?
Quality metal flashing typically lasts 20 to 30 years or more, and copper flashing can last 50 years or longer. Poor installation, harsh exposure, and incompatible metals shorten that lifespan considerably.
Can you replace flashing without replacing the whole roof?
Yes. We carefully lift the surrounding shingles, install the new step and counter flashing, and reseal everything. A full roof replacement is only needed if the roof itself is at the end of its life.
What is the difference between step flashing and counter flashing?
Step flashing is woven into the shingle courses along the chimney sides to direct water downward. Counter flashing is embedded into the chimney’s mortar joints and folds down over the step flashing. You need both for a truly watertight seal.
Do you guarantee your chimney flashing work?
Absolutely. Every flashing project is backed by our $25,000 workmanship guarantee, on top of the manufacturer’s material warranties.

What is chimney flashing and why does it leak?
Flashing is the metal barrier sealed where your chimney meets the roof — its whole job is keeping water out of that joint. It leaks when the metal corrodes, the sealant dries and cracks in our NC heat, or step flashing was installed poorly (a common shortcut). Because the chimney is a big vertical surface catching wind-driven rain, failed flashing lets in a lot of water fast. It’s one of the most common leak sources we repair in the Triangle.
Can a roofer fix chimney flashing, or do I need a chimney company?
A roofer — flashing is roofing work, not chimney work. The flashing lives on your roof and ties into the shingles, so roofing contractors are the right trade for it. That said, we do chimney flashing only: we don’t do general chimney services like masonry repair, chimney caps, or flue work. If your issue is the flashing where the chimney meets the roof, that’s us — call (919) 576-9420 for a free inspection. If it’s the chimney structure itself, we’ll tell you honestly and point you to the right specialist.
