Flashing is the thin metal that seals the joints and transitions on your roof, the exact spots where leaks tend to start.
Sherak fabricates custom flashing on site to fit the unique angles and joints of your roof, so every vulnerable area is sealed and protected.
What is custom flashing?
Custom flashing is thin metal installed at the joints and intersections of your roof to keep water out. It goes around chimneys, skylights, vents, and other roof penetrations, and along the valleys where roof sections meet. Because it is fabricated to your roof's exact dimensions and angles, every vulnerable area is correctly protected.
Why is flashing important?
Flashing keeps rainwater and snowmelt from getting into your roof structure. Without it, water penetrates and causes leaks, rot, mold, and structural damage, and even slow seepage weakens a roof over time. Good custom flashing seals every corner and joint for long-term waterproofing.
Types of custom flashing we install
We fabricate flashing to fit your roof's exact design, using durable aluminum and galvanized steel:
- Chimney flashing: seals around chimneys to stop water seeping in
- Valley flashing: channels water away where two roof slopes meet
- Step flashing: used where the roof meets vertical walls, dormers, or sidewalls
- Drip edge flashing: at the roof edges to protect the fascia and siding
- Vent and skylight flashing: sealed around penetrations to prevent leaks
How much does custom flashing cost?
Cost depends on your roof's size, the materials, and the complexity of the job. Most homeowners pay $500 to $2,000 for installation, with larger or more complex roofs costing more. Contact Sherak for a free, accurate estimate.
