CHIMNEY FLASHING
At LUIS GUAMAN HOME IMPROVEMENT CORP, we provide specialized installation and repair services for chimney flashing in New York and New Jersey, serving properties in New York County, Westchester County, Orange County, Rockland County, and Stony Point.
The flashing around the chimney is an essential component of the roofing system, as it seals the connection between the vertical chimney structure and the roof surface, preventing leaks and structural damage.
When flashing is deteriorated, improperly installed, or separated, it can become one of the most common sources of water intrusion in a home. Proper technical intervention is essential to prevent moisture issues in attics, ceilings, and interior structures.

Common chimney flashing problems
- Cracked or deteriorated seals.
- Corrosion on metal sheets.
- Separation between the chimney and the roofing material.
- Visible leaks after heavy rainfall.
- Previous installation without a proper step flashing system.
Our work procedure
Each project begins with a detailed inspection to determine whether the issue requires a targeted repair or full replacement of the flashing system.
- Removal of deteriorated flashing.
- Installation of new step flashing and counter flashing.
- Application of technical sealing on critical joints.
- Proper integration with the roof’s waterproofing system.
- Final inspection to verify watertightness and structural fit.
Our focus is to ensure that the connection point between the chimney and the roof is properly sealed and fully integrated into the overall roofing system.
At LUIS GUAMAN HOME IMPROVEMENT CORP, we offer free inspections and estimates to evaluate the condition of the flashing and clearly explain the scope of work before beginning any intervention.
