C3B and C4B Bow Roof Installation Instructions

Polymer window roofs are designed to be installed with auxiliary casing provided by window manufacturer or others .See illustration below. This casing is sometimes no more than a piece of 1"x1" pine to fill in the space between the platform or head board and the outer edge of the window and is used to provide fastening for the roof. Sometimes this piece could be a little wider to better fill in the space between the window and the roof or perhaps higher and wider to provide space for a crown molding.

  1. Install Auxiliary casing: install trim strip.

  2. Caulk surface of flashing and other surfaces of roof where it meets building and window.

  3. These bow window roofs are attached in front by fitting over trim strip.

  4. After the roof has been attached to the window use galvanized or stainless steel roofing nails to attach the roof flashing to the building. Use the nail holes provided or drill at least 3/16" holes. Do not nail tight: leave room for expansion.

  5. Install the siding: do not nail through the flashing flange.

  6. No other finishing is recommended and may void warranty.

  7. Care must be taken to insure that windows are installed in accordance with manufacturers instructions including support by cables or knee brackets to keep windows from sagging.
