Roof Flashing Repair

Roof flashing is a thin sheet of metal—often aluminum, copper, or galvanized steel—installed in vulnerable areas of your roof to direct water away from joints, seams, and penetrations. These spots include chimneys, skylights, roof valleys, vent pipes, and the intersection between roof and wall surfaces. Without properly installed and maintained flashing, water can seep into your home, causing leaks, wood rot, mold growth, and structural deterioration. In a climate like Kansas City’s, with frequent rain, hail, and freeze-thaw cycles, flashing is one of the most critical components for long-term roof health.

Signs of flashing damage aren’t always obvious from the ground. However, there are several indicators to watch for:

• Water stains or discoloration on ceilings or walls inside your home.
• Rust or corrosion visible near roof edges or around chimneys.
• Loose, bent, or missing metal pieces where the roof meets vertical structures.
• Cracked or missing sealant along roof joints.
• Shingles near flashing areas that appear lifted, warped, or loose.
  Because flashing is often partially hidden under shingles or siding, a professional inspection is the most reliable way to confirm its condition.

Several factors can lead to flashing problems:

• Weather exposure – Heavy rain, snow, hail, and extreme heat can weaken both metal and sealants over time.
• Corrosion – Even treated metals can rust when exposed to standing water or harsh elements.
• Poor installation – Incorrect overlaps, inadequate sealing, or improper fastener placement can lead to early failure.
• Building movement – Expansion and contraction from temperature changes can cause flashing to pull away from the roof.
• Storm damage – High winds or hail can bend or dislodge flashing entirely.

In many cases, flashing can be repaired rather than fully replaced. If the damage is limited to a small section – such as a loose fastener, cracked sealant, or minor corrosion – targeted repairs can restore its effectiveness. However, if the flashing is extensively rusted, warped, or incorrectly installed, replacement may be the better long-term solution. During our inspection, we evaluate the condition and recommend the most cost-effective approach for your situation.

The repair time depends on several factors, including the extent of the damage, the location of the flashing, and the complexity of the repair. Minor repairs may take only a couple of hours, while replacing flashing in multiple areas or in hard-to-reach spots—such as tall chimneys or steep roof valleys—can take longer. We always strive to complete repairs efficiently while maintaining thorough, precise workmanship.

If your roof leak is caused by damaged flashing, then yes—repairing or replacing that flashing should stop the leak. However, leaks can sometimes have multiple sources, such as damaged shingles, clogged gutters, or underlayment issues. That’s why we start every job with a detailed inspection to identify all potential entry points for water, ensuring the repair addresses the root cause.

Because of the region’s variable weather, we recommend having your flashing checked at least once a year, ideally in the spring or fall. It’s also wise to schedule an inspection after major storms, especially those involving hail or high winds. Regular checks help catch small issues before they develop into costly repairs.

We work with durable, weather-resistant materials suited to your specific roof type and style. Common options include:

• Aluminum – Lightweight and corrosion-resistant.
• Copper – Extremely durable with a long lifespan, often used for high-end projects.
• Galvanized steel – Strong and cost-effective for many residential roofs.
  We match new materials to your existing roof for both performance and appearance.

Yes, flashing repairs can be performed during colder months, although extreme weather may delay work for safety reasons. In fact, repairing flashing in winter can prevent ice dams and further water infiltration during freeze-thaw cycles. If immediate repairs aren’t possible, we can apply temporary waterproofing measures until conditions improve.

Simply fill out our online contact form with your name, address, and a brief description of your roof issue. We’ll schedule an inspection, assess the condition of your flashing, and provide a clear, detailed estimate. Acting quickly can prevent additional damage and save you from more expensive repairs in the future.
