Signs You Need a New Roof
If you notice that the metal roof above your bay window is discolored, warped, or showing signs of rust, it’s a clear indication that a roof repair or Replacement may be necessary. Over time, exposure to the elements can cause metal roofing to deteriorate, leading to potential leaks and structural damage.

Step-by-Step Metal Roof Replacement for Bay and Bow Windows
Remove the old roof above the bay or bow window.
Inspect the wood decking – if it’s in good condition, we re-screw it; if it’s damaged, we replace the rotted wood.
Install 1/2″ rigid foam insulation for added energy efficiency.
Apply ice and water shield to fully waterproof the area.
Install custom metal roofing, with options like galvanized steel or copper.
Add a gutter system above the window to properly manage rainwater and prevent leaks.
Custom-Fabricated Metal & Copper Roofing Solutions
Our trucks are fully equipped with metal bending machines, allowing us to fabricate custom metal and copper panels directly on-site. For metal roofing, we typically use 24-gauge steel, while for copper installations, we work with 16 oz or 20 oz copper sheets.
Each sheet is hand-formed and adjusted on location to fit the exact shape and structure of your roof decking. This ensures a precise fit, clean finish.
