Book an installationChimney flashing is a thin sheet of metal installed at the intersection where the chimney meets the roof. Its primary purpose is to create a watertight seal, preventing rainwater from seeping into your home.
Without proper flashing—or if the flashing becomes damaged—water can leak into your attic, walls, or ceilings, leading to mold, wood rot, and even structural damage.

Even if you're not seeing signs inside your home, chimney flashing should be inspected regularly—especially after severe weather.
Our professionals follow a step-by-step approach to ensure your chimney is properly sealed:
We examine the condition of your existing flashing to assess the damage—cracks, corrosion, poor sealing, or structural gaps.
We clean the flashing area, remove old caulk or sealant, and clear away any debris to ensure proper adhesion.
We fasten the flashing securely and reinforce the seal with premium caulking to prevent leaks.
We test the repairs, check for leaks, and ensure the seal is weatherproof and watertight.
DIY chimney flashing repair is risky and typically requires climbing on a roof. For safety and effectiveness, we highly recommend professional service.
The cost to repair or replace chimney flashing can vary based on several factors, including the type of material used, the size of the chimney, the slope of the roof, and how extensive the damage is.
In addition to material and project-specific costs, labor rates also influence the total price. These typically range from $75 to $100 per hour, varying by location and the complexity of the job.
While small flashing issues may seem manageable, professional repair ensures long-term protection, safety, and compliance with local building codes.
