Attached or freestanding, and the roof tie-in
An attached cover joins the house one of two ways. New rafters can continue the existing roof plane or form a gable that meets it. Or a lower roof can hang from a ledger bolted to the wall framing, which is simpler but limited by eave height, since a low eave leaves little room for slope.
Either way, the joint is about water. Flashing must carry rain over the seam where new roofing meets old, and the pitch must suit the roofing chosen. If an old gutter ends up beneath the new roof, downspouts are rerouted so a cloudburst doesn’t dump against the foundation. We also check that existing walls and rafters can carry the added weight.
A freestanding cover stands on its own posts and beams. It fits beside a pool, at the edge of a slope facing the view, or where the house roof is too low or complex to join neatly. With no wall to lean on, its bracing and footings resist wind alone.
