Most roof anchor installations require the removal of shingles to install. This can pose a problem, especially on older roofs with brittle shingles. No need to remove the ridge cap to install fall arrest anchors because this flashing allows you to install anchors directly over your existing roofing material.
The D- Minus anchor can be mounted directly over existing asphalt shingle roofs without removing any shingles. To cover the anchor and fasteners and protect it from the elements we invented the RetroFlash. It is a special metal flashing made from 20-gauge metal that slips under the course of roofing just above the anchor. It is held in place by the roofing material and the caulking used during installation. This product can be painted to match the color of the roofing material.
- D- into Top-Chord/Truss: Simply center the anchor over the truss and nail or screw the anchor down securely.s
- D- through Roof Decking into Backer-Board: Install our ¾” backer board under the current roof sheeting. Screw the D- Anchor through the roofing/decking and into the backer board
Our 4-page Instruction/Specification Manual is very comprehensive and has the information needed to install the anchor and flashing system.
