Ledger on the house or posts on all four corners?
An attached cover borrows the house for one side of its support, which saves two columns and lets the new roof flow off the existing eave. It works cleanly on newer homes in Pecan Grove, Long Meadow Farms, and Harvest Green, where the framing is known and the wall behind the ledger is straightforward. On older in-town houses the picture is less certain. The wall may carry old siding over odd framing, the eave may sit too low for a workable pitch, and the rafters may not want the extra load. That is where a framing inspection before design earns its keep.
A freestanding cover stands on its own footings a few inches off the house, with flashing bridging the gap so rain does not run down the wall. It costs a little more in posts and concrete, but it sidesteps every question about what the old roof can hold and it never disturbs the existing shingles or fascia. On a historic-core property with a low eave or a delicate exterior, freestanding is often the honest answer. We recommend whichever the house is asking for, not whichever is simpler to price, and the engineer's drawing reflects that choice.
