Roof Application

Notice: Prior to beginning your installation use a check list to make sure you have everything you will need to install your metal roof.  (See Sect. 1 – Pg. 12 in the complete PDF version link below)

If installing over existing shingles the roof should be strapped with minimum 1″ x 4″ strapping at 24″ centres.

  • Panel Installation should begin at the gable end of the roof opposite the prevailing rain bearing wind (this will help ensure that wind driven rain will not penetrate the lap).
  • The minimum roof slope recommended is 4″ in 12″ of rise (4/12 pitch). You can apply metal roofing to as low a pitch between 2″ in 12″ of rise and less than 4″ in 12″ of rise. This is called a low slope application and requires extra steps (see above under roof pitch).

Siding Application

The standard fastening and overlap patterns should be used when installing siding to ensure optimum performance.  Hemmed corner flashings should be used for strong neat corners.  Other flashings you will use when installing side panels are drip cap (over windows), J-Trim (around windows and doors), and door jamb flashing.  You should not run siding panels all the way to the ground, and the bottom edge should be terminated on a base flashing.  When the wall consists of more than one panel in each vertical row, install panels from the bottom up so water is directed away from, and not into, the lap joints.  Siding panels installed horizontally should have Butyl tape or caulking applied at the vertical laps, as this will ensure weather-tite joints.
