Watertight and Leak-Free
Chimney Flashing Repair in
Vermont & New Hampshire
The point where your chimney meets your roofline is one of the most exposed spots on your entire home. Flashing — the custom-formed metal that bridges that gap — is what keeps rain, snow, and snowmelt from working their way into your attic and walls. When it's in good shape, you never think about it. When it's failing, you'll usually notice water stains on the ceiling long before you figure out where they're actually coming from.
Chimney Savers repairs and installs chimney flashing across Vermont and New Hampshire. Whether your flashing has pulled away, rusted through, or was never properly installed to begin with, we'll assess the situation honestly and take care of it the right way — a custom fit to your roof, not a coat of roofing cement over an old problem.
Why Proper Chimney Flashing Matters
A lasting flashing repair starts with understanding exactly where the problem is, then building a solution that's fitted to your specific roof, chimney, and climate. Here's how we approach it.
Site Assessment & Inspection
We access your roof and evaluate the flashing from the outside, and check the attic space where it's accessible, to map the issue and understand what's actually going on before we recommend anything.
Planning the Right Repair
Not every flashing problem calls for the same solution. We determine whether the existing metal can be re-secured and sealed, or whether a partial or full replacement is the right path — and we explain our reasoning clearly so you can make an informed decision.
Fixed-Price Proposal
Before any work begins, you'll receive a written proposal covering the full scope, materials, and total cost. No surprises at the end — just honest, upfront pricing.
Expert Flashing Repair or Replacement
We custom-form and install flashing fitted to your specific roof pitch and chimney dimensions — base flashing woven under the shingles, counter-flashing anchored into the mortar joints above. We do the work the right way, with materials built to hold up through years of New England winters.
Documentation & 10-Year Workmanship Warranty
We document the repair with before-and-after photos and walk you through exactly what was done. Every qualifying repair is backed by our 10-Year Workmanship Warranty for added peace of mind.
Trusted by Your Neighbors
Reliable, on-time, trustworthy - they did waterproof the exterior masonry and replaced counter flashing. Great team and overall excellent experience and can highly recommend them.

Not sure if your chimney flashing needs repair?
Here are the most common signs your flashing is failing.
Water Stains Near the Chimney
Damp spots, discoloration, or active dripping on ceilings or walls near the chimney, especially after heavy rain or snowmelt.
Old or Missing Caulk Along the Metal
Dried-out, cracked, or missing sealant along the edge of the flashing where it meets the chimney or the shingles below.
Leaks During Rain but Not Otherwise
Water showing up inside the firebox or on the interior masonry mainly during heavy rainstorms, which usually points to the flashing rather than the crown or liner.
Shingles Lifting Near the Base
Shingles right next to the chimney that are buckling, curling, or starting to lift are often a sign that water has been pooling underneath them.
Visibly Damaged or Lifted Metal
Flashing around the base of the chimney that looks bent, rusted, or is physically pulling away from the roofline.
Our Chimney
Flashing Repair Process
A permanent flashing repair requires a dual-layered approach. We don't just slop roofing cement over old leaks; we engineer a custom, interlocked metal system tailored specifically to your roof pitch.
Comprehensive Leak & Decking Assessment
We inspect the flashing structure from both the roof and the interior attic space to map the leak and evaluate the structural integrity of the surrounding wood decking.
Old Material Removal & Clean Down
Our team carefully strips away failing metal sheets, old roofing tar, and degraded sealants, exposing a clean masonry and shingle base for a flawless new installation.
Precision Base Flashing Installation
We custom-bend and weave individual metal step-flashing sheets directly under your existing shingles and up against the brickwork, creating a secure primary water shield.
Deep-Reglet Counter-Flashing Integration
We cut a precise horizontal groove (reglet) into your chimney's mortar joints, embedding a secondary layer of metal counter-flashing that sheds roof water seamlessly over the base layer.
Documentation & Warranty
We stand behind every repair we perform. That's why we thoroughly document our work with before-and-after photos and conduct quality control reviews to ensure every project meets our high standards. For added peace of mind, all qualifying repairs are backed by our 10-Year Workmanship Warranty.

Frequently Asked Questions
How do I know if my flashing is leaking or if it's my shingles?
It can be difficult to tell from inside the house — water travels along rafters and framing before it shows up as a stain, so the visible damage is rarely directly below the actual entry point. The most reliable way to know is to have someone who understands both roofing and masonry do a proper inspection. Chimney Savers assesses the full chimney penetration — the flashing, the counter flashing, the step flashing along the sides, and the condition of the surrounding shingles — so you get an honest answer rather than a guess. In many cases we find both are contributing to the problem.
Will my homeowner's insurance cover chimney flashing repair?
It depends on the cause of the damage. If your flashing failed due to a sudden event — like storm damage or a fallen branch — your homeowner's insurance policy may cover the repair. If it failed due to age, wear, or deferred maintenance, most policies will not. Either way, we provide full photo documentation of the damage before and after the repair, which gives you exactly what you need to submit a claim or support a dispute. We recommend contacting your insurer before the repair is completed if you believe the damage may be covered.
What is the difference between step flashing and counter flashing?
Flashing is a two-part system. Step flashing consists of L-shaped pieces of sheet metal woven into the shingles along each side of the chimney — it redirects water away from the roof-chimney joint. Counter flashing is embedded into the masonry and hangs over the step flashing, sealing the joint against water working behind the step flashing. Both components must be intact for the system to work. On standing seam metal roofs — common on older Vermont homes — the step flashing is integrated into the roofing material itself.
Are there temporary fixes for failed chimney flashing?
Yes. Flash Seal, a flexible waterproof membrane, can solve problem leaks around chimney bases, stacks, and vents and carries a 7-year warranty when used with reinforcement fabric. We use it in appropriate situations. Our preference, however, is always to repair with proper step and counter flashing techniques — because temporary fixes on a failed system are just a delayed version of the same problem.
How long does chimney flashing last?
Properly installed metal or lead flashing on a well-maintained chimney can last 30 years or more. Sealant-based repairs and lower-quality materials have much shorter lifespans, particularly in Vermont and New Hampshire's climate. The freeze-thaw cycle and heavy snow loads accelerate deterioration of any marginal installation.
Can damaged flashing cause interior mold?
Yes. Water that enters through failed flashing can saturate insulation, soak into framing lumber, and create the moisture conditions necessary for mold growth — all in areas that are not visible until the problem is significant. The sooner a flashing failure is repaired, the lower the risk of secondary moisture damage.
