Why Some Chimney Flashing Isn’t Replaced During a Re-Roof — And What That Means for You

#1. Flashing Often Hides in Siding or Stucco

Much of the flashing around chimneys (step flashing, counter flashing, and back pan flashing) is tucked under siding, stucco, or even set into brick mortar. That placement protects it from the elements — but it also makes it inaccessible during a standard re-roof.

Removing siding or brickwork just to access flashing is outside the normal scope of roofing work and often requires another trade, like a siding installer.

 

#2. What We Replace — and What We Reinforce

At Braymar Roofing & Repairs Ltd., our practice follows industry standards:

  • ✔️ We replace accessible flashing such as valleys, drip edges, vent boots, and exposed areas around chimneys.
  • 🔒 We reinforce hidden flashing under siding or masonry by carefully tying in new shingles, applying water-resistant membranes, and sealing the area.
  • We note when another trade is required if full removal and replacement of hidden flashing is desired.

This ensures your new roof ties into the existing system and stays watertight, even if not every flashing piece is fully replaced.

 

#3. Our Workmanship Warranty

Our workmanship warranty covers the roof and all flashing that is accessible during installation. If flashing hidden under siding or mortar fails in the future, it isn’t a defect in the new roof — it’s a pre-existing condition that wasn’t part of the roofing scope.

We highlight this upfront so there are no surprises later.
