Chimney Repair & Flashing Services
King, Pierce & Snohomish County
Chimneys are one of the most common sources of roof leaks in the Pacific Northwest — and one of the most frequently misdiagnosed. Covertrust Roofing Solutions provides professional chimney repair and waterproofing services for residential properties across King, Pierce and Snohomish Counties. We inspect every chimney as part of a full physical roof walk, identifying deterioration, flashing failure and water ingress points that less thorough inspections routinely miss.

Why Chimneys
Leak
A chimney is a penetration through the roof plane, and every penetration is a potential failure point. In the Pacific Northwest, the combination of sustained rainfall, temperature cycling and freeze-thaw movement accelerates deterioration at the chimney interface faster than almost anywhere else on the roof.
The most common causes of chimney-related leaks include:
The metal flashing that seals the junction between the chimney and the roof surface degrades over time, pulls away from the masonry, and allows water to track directly into the structure.
Cracked or eroded mortar joints absorb water, which then migrates down through the chimney chase and into the roof assembly.
A chimney cricket is a small, peaked diverter installed behind wide chimneys to redirect water around the chimney rather than allowing it to pond against the back face — its absence is a leading cause of chronic leaks on wider chimneys.
A damaged or missing cap allows direct water entry into the flue and accelerates deterioration of the masonry below.

Warranty Transparency
Clarity Over
Confusion.
At Covertrust Roofing Solutions, we believe homeowners deserve clarity, not confusion. Most roofing companies do not explain how warranties really work — and some even mislead homeowners.
Material Ratings vs. Warranty
When distributors reference 20-year, 30-year, 40-year, or 50-year shingles, these numbers describe the grade, thickness, durability, and expected lifespan — not the warranty. Many roofers blur the line between lifespan and warranty on purpose.
How long shingles may last under normal weather conditions.
A manufacturer’s promise to cover defects, not wear and tear.
How Warranties Actually Work
Most manufacturers cover defective materials for the first 10 years (non-prorated), covering both material and labor. After 10 years, warranties become prorated — dropping more than 2% per year. The longer you own the roof, the less the warranty is worth.
Some manufacturers offer extended non-prorated warranties (40–50 years) but only to contractors who meet strict installation standards, use full roofing systems, and maintain manufacturer certifications.
The Covertrust Advantage
Because Covertrust Roofing Solutions follows strict manufacturer requirements, our clients may qualify for enhanced, longer warranties that many contractors can’t offer. We install every roof to specification, use proper accessories, and ensure ventilation and flashing meet all standards. If a contractor cuts corners, the warranty becomes void — a fact many roofers never mention.
Don't Wait
Concerned About
Your Chimney?
If you’ve noticed water staining near your chimney, damp patches on internal walls or deteriorating brickwork, don’t delay. Chimney-related leaks rarely resolve on their own and typically worsen through the wet season.
