Lift Your Shade Sail with a Roof Anchor Mast Fixing a shade sail directly to a fascia or gutter line rarely holds up under real lateral load, defeating the purpose of installing one in the first place. A shade sail roof anchor solves this with a raised steel mast that bolts to the rafter, wall top plate and wall studs, lifting the sail's attachment point above the roofline so it clears the gutter entirely. Roof Extenda's Shade Sail Anchor is Australian patented and strength tested, with engineer computations available and weather seal variants suited to both tile and metal roofs.
