Layered metalwork, not a bead of caulk

Custom chimney flashing for a durable roof connection

Step flashing, apron flashing, counterflashing, back pans and crickets fabricated to direct roof water around the chimney.

06

A reliable chimney flashing assembly is layered with the roofing and masonry so water is redirected before sealant becomes the only defense. The design changes with roof pitch, chimney width, roofing material and existing counterflashing detail. We evaluate the whole intersection, including the uphill side where water and snow can collect.

System options

Flashing metals and system options

Metal selection affects appearance, fabrication, corrosion resistance and service life. Dissimilar materials must be considered before combining systems.

01

Copper flashing

Best forPremium long-life work and traditional masonry homes

Highly formable and durable, with a natural patina over time. Common assemblies use custom apron, step and counterflashing pieces with carefully formed corners and masonry reglets.

02

Lead-coated copper

Best forPremium soldered work with a muted gray finish

Combines copper's fabrication qualities with a traditional gray exterior. Material compatibility, runoff and local requirements are reviewed before specification.

03

Stainless steel

Best forHigh corrosion resistance and crisp custom fabrication

A durable option for selected roof and masonry conditions. It requires proper forming, fastening and isolation from incompatible metals.

04

Galvanized steel

Best forCost-conscious repairs and compatible roofing systems

A common painted or mill-finish option. Cut edges, fasteners and coating condition require careful detailing because corrosion resistance depends on the protective zinc layer.

05

Aluminum flashing

Best forCertain compatible residential roof assemblies

Lightweight and corrosion resistant in many environments, but softer and not compatible with every masonry or metal condition. Gauge, finish and isolation details matter.

06

Cricket or saddle integration

Best forWide chimneys or uphill areas that collect water and debris

Creates a peaked water-diversion structure behind the chimney. The cricket is integrated with underlayment, roofing and back-pan flashing as one assembly.

What to look for

Signs the flashing assembly should be opened and evaluated

  • Interior staining appears near the chimney after rain
  • Roof cement or caulk is cracking around the base
  • Metal is loose, rusted, punctured or pulling from masonry
  • The uphill side traps leaves, snow or standing water
  • Roofing was replaced without rebuilding the chimney flashing
What the scope can include

A complete written scope

  1. Roof pitch, masonry and roofing material assessment
  2. Removal of failed surface patches within the written scope
  3. Apron, step, back-pan and counterflashing fabrication
  4. Reglet cutting or approved counterflashing attachment
  5. Cricket, underlayment and roof repair coordination when included
How the work moves

Our service process

  1. Trace leak patterns and inspect all four sides of the chimney
  2. Select compatible metal and the correct layered assembly
  3. Open the work area while protecting surrounding roofing
  4. Fabricate and integrate each flashing component
  5. Seal designated joints and complete a final water-shedding review
From selection to final review

A clear project path, with expectations in writing.

01

Inspection & documentation

We inspect accessible conditions, take measurements and document the parts of the system that shape your repair or installation options.

02

System options & written scope

You receive practical material and system choices, a defined scope of work and clear exclusions where hidden conditions may exist.

03

Contract, deposit & scheduling

Once you select your system:

  • We sign a clear, written contract
  • A 30% deposit is collected
  • We schedule your project
04

Installation & progress documentation

We protect the work area, install the approved scope and document important conditions and completed details as the project moves forward.

05

Cleanup & final inspection

We clean the property thoroughly. Most exterior construction sites are approximately 90-99% clean the same day. For qualifying multi-day masonry and exterior projects, our next-day closeout can include:

  • A final inspection
  • An additional magnetic sweep
  • Final drone photos when conditions and location allow
  • A complete quality-control review

Exact payment milestones, closeout steps and return visits are stated in the written contract for the selected project.

Service questions

Details worth understanding.

Final specifications depend on the inspected conditions, appliance listing, selected manufacturer and applicable local requirements.

Can chimney flashing be fixed with sealant alone?+

Sealant can maintain specific joints, but it does not replace missing step flashing, failed counterflashing or an undersized back pan. A repair should correct the path of water, not only cover the visible gap.

Is copper always the best choice?+

Copper is a premium, durable material, but the best choice also depends on the roof, existing metals, appearance and budget. Correct detailing is more important than using an expensive metal incorrectly.
