Tips for A Quality Metal Roof Installation
- Install roof decking 5/8" or thicker.
- Apply a high quality underlayment. We use High-Temp Ice and Water Shield by W.R. Grace, exclusively.
- Install 24 gauge metal.
- Always install thru-wall flashings where vertical walls are above lower roofs.
- Install thru-wall flashings and caps on all chimneys.
- Never allow plumbing or mechanical roof vent stacks to fall in standing seam.
- Clad vent stacks with the same material as the roof.
- Install roof panels with concealed fasteners and space them according to manufacturer's specifications (generally 24").
- Insure all roof material is obtained from same master coils to avoid color or shade variation.
- Complete painting or staining of upper walls and eaves and install gutter and downspouts before installing lower roofs.
- Determine gutter type before installing roof panels, as some brackets position the gutter up to 3/4" from fascia. With open rafter tails or where a crown moulding is present, brackets should be installed prior to the roofing.
- Fabricate and install drip edge so that gutter will be behind it.
- Do not install mechanical drain lines so that they drip onto the roof panels (ugly staining will occur).
- Avoid foot traffic on roof panels.
- Research the experience of your roofing contractor and inspect some of their completed projects.
