Custom Metal Work & Specialty Flashing

Precision Metal Work Built For Your Roof, Home, & Project

At Guaranteed Roofing, our custom metal work services include bay windows, regular metal bay window metal work, specialty flashing, and on-site metal fabrication. Each piece is measured, formed and installed to integrate properly with your roofing system and protect your home.

Our Custom Metal Work Services

Copper Bay Windows

We provide custom copper metal work for bay windows and architectural details, including properly formed transitions and flashing designed to direct water away from the structure.

Bay Window Metal Work

We fabricate and install custom metalwork for bay windows to create a clean, weather-resistant transition between the window structure, roof and exterior of the home.

Specialty Flashing

While many roofing applications can use standard flashing components, some homes and roofing details require something more specific. We fabricate specialty flashing for unique application

On-Site Metal Fabrication

Some roofing projects require a solution that cannot be accurately produced from standard materials or components. Our team can perform on-site metal fabrication, allowing us to measure, form and modify metal to suit the actual conditions of your home or project.

  • Bay windows and architectural projections
  • Specialty flashing applications
  • Difficult or unusual roof details

Frequently Asked Questions About Custom Metal Work

What is custom metal work in roofing?

Custom metal work involves fabricating metal components specifically for a home’s roofing or architectural features. This can include custom flashing, bay window metalwork, roof transitions and other details where standard components aren’t suitable.

The appropriate material depends on the application, design requirements and existing roofing system. Copper is commonly used for architectural features such as bay windows, while other metal options may be appropriate for flashing and specialty applications.

Yes. Guaranteed Roofing provides specialty flashing for unique roofing details and areas where standard flashing components may not provide the right fit or configuration.

Yes, when the project requires it. On-site fabrication allows our team to measure and form metal to suit the actual conditions of the roof or architectural feature.

Flashing helps direct water away from vulnerable areas where different roofing materials or building components meet. Properly designed and installed flashing can help reduce the risk of water infiltration and damage.

We focus on long-term solutions, not quick fixes. With over 30 years of experience, we provide honest assessments, quality workmanship, and dependable service backed by a family-owned reputation.
