Frequently Asked Questions
What is chimney flashing & sealing, and why is it important?
Chimney flashing & sealing is the metal system installed where the chimney meets the roof. Its job is to seal that vulnerable joint and keep water from penetrating into your home. Proper chimney flashing and sealing prevents leaks, mold growth, framing decay, and interior water damage.
How do I know if my chimney flashing is leaking?
Common signs of a chimney flashing leak include water stains around the chimney, damp drywall, bubbling paint, musty odors, or visible rust or gaps in the flashing. During heavy rain, you may also notice drips near the fireplace or in the attic. Issues with chimney flashing & sealing are often the root cause, and a professional roofing inspection can confirm the exact source and location of the leak.
What causes chimney flashing to fail?
Flashing can deteriorate due to age, rust, poor installation, wind damage, settling of the home, or cracks in the chimney mortar. Temperature changes also cause expansion and contraction, which can loosen flashing over time. Even minor gaps can let water in.
Can chimney leaks be fixed without replacing the entire roof?
Yes. Chimney leaks are usually localized issues. In most cases, we can repair or replace the flashing, seal gaps, and correct water-entry points without needing to replace the entire roof. Only severe structural issues would require larger repairs.
What is chimney sealing, and how does it help?
Chimney sealing involves applying a waterproof sealant or coating around the flashing, masonry joints, counter-flashing, and other areas prone to water penetration. This creates a watertight barrier that prevents leaks and extends the lifespan of both the chimney and roof.
How long does chimney flashing or sealing last?
High-quality metal flashing can last 20–30 years when properly installed as part of chimney flashing & sealing. Sealants typically last 5–10 years, depending on weather exposure and the materials used. Regular inspections of chimney flashing & sealing help catch small issues before they turn into costly repairs.
Can you repair all chimney types (brick, metal, prefab, etc.)?
Yes. We work with all chimney configurations including brick masonry chimneys, prefab metal chimneys, wood-burning systems, gas chimney vents, and stone chimneys. Each type requires a slightly different flashing and sealing method, but we handle them all.
How soon can you repair my chimney flashing if it’s leaking?
If water is entering the home, we can typically schedule repairs quickly — often within 24–48 hours. During severe weather or emergency situations, we can apply temporary waterproofing or tarping to stop active leaks until permanent repairs can be safely completed.
Should I trim trees before getting chimney flashing repaired or sealed?
In many cases, yes. Trimming trees reduces debris buildup, prevents impact damage, and improves long-term flashing performance. Schedule professional tree care here: Tree Trimming & Removal Services.
How do chimney repairs connect to landscaping and drainage?
Your chimney flashing and sealing protect against water intrusion while your landscaping controls how water drains around the property, so when homeowners use Washington Roofing together with Washington Landscaping, they help protect the house, foundation, and yard.
