Bracket Fastening

Overview

This procedure covers how to install the accessory bracket for securing roof fixtures (for example, a snow fence or chimney supports) to the Solar Roof. The bracket does not support satellite dish or lightning rod applications.

Tools and Equipment:

  • Accessory Bracket Kit
  • Measuring Tape
  • Metal Snips
  • ½ in Socket Bit
  • 3/16 in Drill Bit
  • Hammer
  • Impact Driver
  • Caulk Gun and Sealant

Work Instructions:

  1. Identify the tile course where the accessory bracket(s) will be installed. When installing a snow fence, refer to the manufacturer's installation instructions or job plan set for allowable spans, mounting schedules, and cantilever dimensions to determine the exact location and quantity of accessory anchors to be installed.

    1 - Snow Fence

  2. First, determine the locations of rafters used to anchor the brackets. The below example shows bracket installation for mounting a snow fence.

    1 - Rafter spacing can vary; always double-check with a hammer and if necessary, chalk a line to have a reference of where the rafter location may be.

  3. Next is determining the location of the bracket on the metal tile. The bracket must be positioned vertically with the rounded edge up-roof.

    The bracket can land between 3 in above the leading edge of the tile and 3 in below the top edge of the tile. This will ensure that the bracket does not interfere with the engagement shoulder/hook of the metal tile.

    1 - Bottom leading edge of the bracket

    2 - Top edge of the tile

    3 - Leading edge of the tile

    CAUTION
    Avoid installing the bracket under the water channels of the tiles. It is best practice to either shift the array or, in cases of chimney supports, move them to the tile course above when possible.
  4. As with installing a snow fence, make sure that the brackets are in line with each other. This can be done by measuring or chalking a line.
  5. Once the location of the bracket has been determined, place the accessory bracket over the rafter location and make pilot holes for the lag screws.
    Clean debris away from the pilot holes.
  6. Add sealant to the bracket and pilot holes, then secure the bracket with three lag screws and bonded washers (provided with the accessory bracket kit).
  7. Once the brackets are installed, begin the tile installation.
    1. When installing metal tiles over a bracket, it is recommended to measure where the bracket is going to sit underneath the tile and mark it on the back of the tile.
  8. At this point, you may need to snip away any supports that are interfering with the bracket.

    1 - Location of the bracket once it is installed

    2 - Snip

  9. Fixtures can now be attached to the accessory bracket. Ensure that all the screws are installed through the accessory bracket. If screws miss the accessory bracket, the fixture will not be secure.

    Note
    PRO TIP: Use a string/chalk line to ensure that the snow fence is installed in a straight line.
  10. Follow the manufacturer's instructions for the assembly and installation of snow fences.
