Metal Roof Flashing Replacement in Dallas, TX

Permanent flashing replacement restores integrity and stops recurring water issues

When a homeowner in the DFW area contacted Shepherd Metal Roofing about an ongoing leak around her skylights, we initially expected a standard resealing job. But as we began our inspection, it quickly became clear that a more permanent solution was needed.

Skylight leaks on metal roofs are deceptively common, and just as easy to underestimate. Many homeowners assume that a fresh bead of sealant will solve the problem, but sealant alone is rarely enough, especially when the issue lies in flashing design or water flow dynamics.

The Initial Symptoms: Skylight Leaks and Panel Movement

The homeowner had noticed water stains appearing near her skylight during rainstorms. She’d also heard rattling noises during wind gusts, indicating loose panels; another early red flag on standing seam metal roofs.

We conducted a thorough on-site inspection and used our metal roofing expertise to pinpoint the root causes:

• Sealant around the skylight frame had failed in several areas
• Water was traveling underneath panels and into the curb framing
• Flashing was improperly installed or deteriorated
• Several panels near the skylight had begun lifting at the seams due to movement and age

The Real Fix: Removing and Rebuilding the Skylight Flashing

Initially, we considered a light repair: resealing joints and re-fastening panels. But after reviewing the project further and consulting with another experienced tech, we made the right call: to fully remove and rebuild the flashing system around the skylight for a permanent, watertight solution.

Here’s what our metal roofing team did:

• Removed and loosened metal panels around both skylights for full access
• Inspected skylight framing for rot or deterioration, fortunately, it was structurally sound
• Removed old flashing and sealant debris
• Fabricated new metal flashing to redirect water away from the curb
• Installed step and counter flashing using proper overlapping techniques
• Sealed seams using premium butyl tape, ensuring a flexible, weather-resistant bond
• Reset metal panels with tight locking at seams and mechanical fasteners

Why Flashing Is the Most Critical Part of Skylight Installation

Flashing is the unsung hero of every successful skylight install. It’s the barrier between the skylight and water intrusion, especially on metal roofs where water can travel far before becoming visible inside.

Poor flashing design can cause:

• Water infiltration during wind-driven rain

• Freeze-thaw separation at seams

• Structural damage to skylight framing

• Premature deterioration of insulation and drywall inside

By rebuilding the flashing properly—not just sealing what’s visible—we restored the homeowner’s confidence and created a long-term, code-compliant fix.

Preventing Leaks on Metal Roofs: Best Practices

At Shepherd Metal Roofing, we always aim to go beyond the fix. Here's what we recommend to anyone experiencing skylight or panel issues:

1. Schedule a full roof inspection every year, especially before and after storm season
2. Look for signs of sealant failure, lifted panels, or water stains on ceilings
3. Don’t rely on caulk alone: rebuilding flashing is often the safest and most cost-effective long-term option
4. Choose a roofing contractor who specializes in metal systems and understands how water moves on your roof
