Room Additions in Temple City
Temple City room additions with a flashed sliding door, a sill pan and a patio that drains away, planned for inland valley rain.
A sliding glass door sits lower than any other opening in the house, so it is the first place water looks for a way in on a Temple City addition. A sloped sill pan under the frame, flashing tucked behind the weather barrier and a patio that falls away from the threshold keep rain and sprinkler water outside.
Under the glass
The sill pan is a sheet metal or molded tray that slopes toward the outside and turns up at both ends, so any water that passes the door track runs out and away from the floor framing. Tape and flashing lap over it in shingle order. The threshold sits above the finished patio surface by enough to clear standing water, and the door track gets weep holes that are kept open through the finish work. A drip edge on the cover or eave above sheds water clear of the track.
The inland valley setting
Inland valley lots get dry spells broken by the odd hard storm, so drainage is sized for a downpour, not a drizzle. The patio slab or pavers pitch away from the wall, and any drain at the doorway ties to a pipe that leaves the yard side. Downspouts near the door are moved clear of the sill. The section through the door goes on the drawings showing the pan and flashing, so a reviewer at the city counter can follow the water path.
Room Additions in Temple City: what people ask
Yes, once the engineer has chosen a beam to cross the span. The wall can be mostly glass, with the door set on a pan and the patio pitched away from it. The pan and flashing detail is the part that keeps that much glass dry.
A ground floor room places the glass at patio level, where drainage matters. A floor above moves living space up and leaves the lawn, subject to a structural check of what exists below. Setbacks and height limits from the city set what either can add.
The tie-in appears as a line of its own, and glass doors with their pan and flashing work are a separate item, so the garden wall stays easy to read. The room totals apart from both.
