Comprehensive Chimney Inspection 

Our repair service starts with a detailed inspection of your chimney flashing. We look for cracks, rust, gaps, and any signs of water infiltration that could compromise your roof or home structure.


Using specialized tools and visual checks, we assess the flashing condition and surrounding roofing materials. This allows us to identify hidden damage that may lead to leaks or rot.


We document all findings and explain the issues clearly. This ensures you understand the extent of the damage and the necessary repairs before any work begins.

High-Quality Flashing Materials Used

We use premium metals like galvanized steel, aluminum, or copper for flashing repairs. These materials resist rust and withstand harsh weather conditions.



Our choice of sealants and waterproof coatings complements the metal's durability, enhancing the watertight barrier around your chimney. This reduces the chance of water penetration and damage.


By selecting high-grade materials, we extend the life of your chimney flashing and prevent frequent repairs, saving you time and money in the future.

Our technicians apply precise, industry-standard methods for flashing repair and replacement. We remove any damaged flashing carefully without harming the surrounding roof structure.



Repairs involve cutting, bending, and securing metal flashing to create tight seals around your chimney. We also inspect and replace any deteriorated sealant to maintain a water-resistant barrier.


Each repair is completed with attention to detail, ensuring no gaps or weak spots remain. Our craftsmanship minimizes future leaks and protects your home’s overall structural health.

Common Chimney Flashing Issues

Chimney flashing faces several challenges that can weaken its effectiveness. These issues often lead to water intrusion and structural concerns if not addressed promptly.

Water Leaks and Damage

Water leaks are the most frequent problem related to chimney flashing. When flashing becomes cracked, warped, or separated from the chimney or roof, water can seep in. This causes damage not only to the chimney structure but also to the roof decking and interior ceilings.



Persistent leaks often result in mold growth, wood rot, and deterioration of surrounding materials. Detecting leaks early is crucial to prevent costly repairs. Regular inspection can reveal signs such as water stains, dampness around the chimney, or peeling paint.

Corrosion and Rust

Flashing materials, often metal, are subject to corrosion and rust when exposed to harsh weather over time. Rust weakens the flashing, making it brittle and prone to breaking or developing holes.



We find that corrosion commonly develops at seams and joints where moisture accumulates. This degradation reduces the flashing’s ability to form a watertight seal. Replacing corroded flashing promptly is necessary to maintain the roof’s integrity.

Improper Installation

Improper installation is a significant factor in flashing failure. Incorrectly installed flashing may not adequately seal gaps between the chimney and roof, allowing water to penetrate.



Common installation errors include insufficient overlap, wrong materials, or poor sealing with inadequate sealant. These mistakes can lead to early deterioration and recurrent leaks. Ensuring flashing is installed by experienced professionals is essential to prevent these issues.
