Here’s a simple way to add a patio roof cover. SkyLift Roof Risers are steel brackets that elevate the patio roof well above the surface of the home’s main roof. To install, you cut a hole in the home’s roof directly above the exterior wall and bolt the bracket to the top plate. (You seal the hole in the roof with standard pipe-jack waterproof flashing.) The elevated design creates a gap between the two roofs, which pulls in natural light, allows trapped heat to escape, and creates more headroom. It also lets you put more of a pitch on the patio roof. Risers come in lengths from 24 to 36 inches and cost $140 to $200.
