Chimney flashing consists of base flashing, step flashing, counter flashing, and a saddle or cricket behind wide chimneys. We repair all four components when separation, cracking, or corrosion causes water to enter the chimney-to-roof junction. Chimney flashing failures are among the most common sources of interior ceiling leaks in Oklahoma homes with masonry chimneys.
Valley flashing directs water runoff through the intersection of two roof slopes. We repair open metal valleys where the flashing has lifted, corroded, or been damaged by foot traffic, and we restore closed-cut valleys where shingles have separated from the valley centerline. Valley flashing failures produce high-volume leaks during heavy rain events common in northeast Oklahoma.
Vent pipe flashing (also called pipe boots or pipe collars) seals the gap between roof decking and plumbing vent pipes, exhaust fans, and gas vents. We replace cracked rubber boots and re-seal deteriorated lead or galvanized pipe collars that no longer create a watertight seal around roof penetrations.
Skylight flashing includes head flashing, sill flashing, and step flashing that integrate the skylight frame with the surrounding roofing material. We repair separated skylight flashing, re-seal counter flashing joints, and replace deteriorated sill flashing that channels water into the interior framing cavity below the skylight unit.
Step flashing consists of individual L-shaped metal pieces woven between shingles at roof-to-wall intersections on dormers, sidewalls, and additions. We replace missing or improperly installed step flashing pieces, re-integrate them with the shingle coursing, and apply appropriate sealant at the wall termination to prevent water entry at these high-risk transition zones.
Counter flashing overlaps base flashing at vertical surfaces such as chimney walls, parapet walls, and roof-to-wall junctions to prevent water from entering behind the base flashing. We repair loose counter flashing embedded in mortar joints, reseal tuck-pointed counter flashing, and replace surface-applied counter flashing that has separated from the vertical substrate.
Drip edge flashing at eaves and rakes directs water off the roof edge and protects the fascia board from moisture infiltration. We repair or replace missing sections of drip edge, re-fasten lifted drip edge flashing, and install proper eave flashing where deteriorated or absent flashing has allowed water to wick back under the starter course and rot the roof decking at the eave line.
Our flashing repair process identifies the failure mechanism, removes deteriorated materials, and restores the watertight seal using appropriate flashing materials and industry-standard installation methods.
Flashing Inspection and Leak Source Identification
We perform a thorough roof inspection to identify which flashing component has failed and locate the water entry point. For interior leaks, we trace water staining back to the roof penetration or transition zone to determine whether the failure is in the base flashing, counter flashing, step flashing, or sealant joint. We document all findings before beginning any repair work.
Deteriorated Flashing Removal
We remove only the failed flashing components — not the entire flashing system — to minimize disruption to the surrounding shingles and roofing materials. Where step flashing has been improperly installed without integration into the shingle coursing, we remove and reinstall the affected shingle courses along with the replacement flashing to ensure proper layering sequence.
Substrate Inspection and Repair
Before installing replacement flashing, we inspect the roof decking, wall sheathing, and framing members beneath the failed flashing area for rot, delamination, or structural damage caused by the water intrusion. We repair or replace damaged substrate materials before proceeding with flashing installation to ensure the new flashing has a sound structural base.
Flashing Material Installation
We install replacement flashing using appropriate metal gauges and profiles for the specific application. Chimney flashing uses step flashing and counter flashing cut from galvanized steel or copper. Vent pipe boots are replaced with EPDM rubber or metal collars rated for the pipe diameter. Valley flashing is installed using 26-gauge galvanized steel with 6-inch minimum overlap at splices. All metal flashing is fastened with corrosion-resistant fasteners and sealed with compatible roofing sealant at joints and terminations.
Final Inspection and Water Test
After flashing installation, we perform a final inspection to verify proper overlap dimensions, secure fastening, and complete sealant coverage at all joints. We document the completed repair with photographs for insurance records and provide the property owner with a written description of the work performed and the materials used.
Flashing failure is rarely caused by a single factor. In northeast Oklahoma, flashing systems are exposed to a combination of conditions that accelerate degradation faster than in more temperate climates.
Thermal Expansion and Contraction
Metal flashing expands in summer heat and contracts in winter cold. Repeated thermal cycling over years fatigues the metal, causes fasteners to work loose, and cracks sealant joints that were applied without expansion allowance.
Sealant Degradation
Roofing sealants applied at flashing terminations have a limited service life. UV exposure, temperature cycling, and moisture infiltration cause sealants to crack, shrink, and lose adhesion — typically within 5 to 10 years of initial application, even on new roofing systems.
Wind Uplift
High wind events common in Oklahoma can lift flashing edges that are secured only by roofing cement rather than mechanical fasteners. Once flashing lifts, water runs directly beneath the metal and into the roofing system at the exact location where the flashing was installed to prevent it.
Improper Installation
Many flashing failures originate from improper installation — inadequate overlap dimensions, missing step flashing pieces, sealant applied instead of mechanical fastening, or using incompatible materials that accelerate corrosion. We frequently repair flashing systems that were installed incorrectly during a prior roofing project.
Galvanic Corrosion
When dissimilar metals come into contact in the presence of moisture — such as aluminum flashing against copper gutters or galvanized steel in contact with treated lumber — galvanic corrosion accelerates metal deterioration far beyond normal weathering rates. We select compatible flashing materials to prevent galvanic reactions at repair locations.
Ice Damming
Ice dams form when heat escaping through the roof deck melts snow that refreezes at the eave line. Backed-up water can infiltrate under flashing at chimneys, in valleys, and at eaves — areas where the roofing system relies on gravity drainage that ice prevents. Proper attic insulation and ventilation reduce ice dam formation, but damaged flashing must be repaired to stop active leaks.
Aces Roofing and Exterior Solutions provides flashing repair services across northeast Oklahoma with a licensed roofing crew experienced in diagnosing flashing failures at chimneys, skylights, roof-to-wall intersections, and vent penetrations. We are a licensed roofing company registered with the Oklahoma Construction Industries Board (CIB License #80002690) and carry full liability and workers' compensation insurance on every job.
Our flashing repair process begins with a thorough inspection to identify the failure mechanism before any materials are touched. We do not apply sealant over failed flashing as a temporary fix — we remove the compromised section and restore the flashing system to proper working condition using appropriate metal gauges, fastening methods, and sealants for the specific application. All flashing repair work is backed by our 10-year labor warranty and we provide written documentation of every repair for insurance and property records.
We also assist property owners with insurance documentation when flashing failures result from storm damage. Our inspection reports and repair estimates are formatted to support homeowners' insurance claims for hail damage, wind damage, and related water intrusion caused by compromised roof flashing.
Aces Roofing provides flashing repair services across northeast Oklahoma. Our service territory includes the following communities and surrounding areas.
Flashing failures produce leaks that appear near roof penetrations and transitions — around chimneys, skylights, vent pipes, dormers, and in roof valleys — rather than in the middle of a large roof surface. If your ceiling stain appears directly below one of these features, failed flashing is a likely cause. A roofing inspection can confirm whether the leak source is the flashing or the surrounding shingles.
Properly installed galvanized steel flashing lasts 20 to 30 years under normal conditions. Copper flashing can last 50 years or more. However, the sealants applied at flashing joints have a shorter service life — typically 5 to 10 years — and require periodic inspection and reapplication to maintain the watertight seal even when the flashing metal itself is still in good condition.
In many cases, yes — particularly when only the flashing has failed and the surrounding shingles remain intact. For step flashing repairs, however, we typically need to temporarily lift or remove the adjacent shingle courses to access and reinstall the individual step flashing pieces correctly. We replace any shingles that are damaged during the access process.
Homeowners insurance typically covers flashing damage caused by covered perils such as hail, wind, or falling objects. Flashing failure due to normal wear and aging is generally not covered. If your flashing failed following a storm, we can provide inspection documentation and a repair estimate formatted to support an insurance claim.
Flashing repair cost depends on the flashing type, the extent of the failure, and whether any substrate repair is needed beneath the failed flashing. Simple sealant reapplication at a vent boot costs significantly less than a full chimney flashing replacement that requires removing and reinstalling multiple shingle courses. We provide written estimates before beginning any repair work so there are no surprises.
