Claremont Full Home Remodeling Under a Sealed Roof
A Claremont whole-house remodel that seals the roof deck with closed-cell foam, routes the kitchen hood and ducts through it, then finishes room by room.
Closed-cell polyurethane foam, bonded to the underside of the roof deck, turns the attic of a Claremont house into space the cooling system already serves. On an inland lot, hard sun bakes the shingles and dry wind drives dust through vents and gaps. A sealed deck keeps both away from the ducts, wiring and hood run that cross overhead. We plan that layer with the kitchen, since the kitchen layout decides where each of those runs travels.
What a sealed roof deck changes upstairs
Once foam covers the deck, the old eave and ridge vents get closed off, because the attic now sits inside the insulated shell. Soft or stained sheathing is found from below and replaced before the foam goes on, since the foam hides those boards for good. Ducts left up there stop running through a space that bakes all afternoon, so they lose far less of the cooled air they carry. Building code calls for an approved ignition or thermal barrier over the foam wherever the attic can be entered, and the permit drawings show which one. New wire and pipe meant for the attic go in ahead of that crew.
Kitchen ventilation in a tighter house
A range hood that moves a lot of air has to pull that air from somewhere, and a sealed house leaks far less of it back in. Past a set airflow, the mechanical code asks for make-up air, usually a motorized damper wired to the hood that opens a duct to the outdoors when the fan starts. The hood duct gets its own insulated, airtight path through the foam to a roof jack. A gas furnace or water heater left in the attic is reviewed for combustion air, and trading it for a sealed-combustion or electric unit is often simpler. The panel then gets checked for that load plus any induction cooktop.
Full Home Remodeling in Claremont: questions to settle first
Tear-out comes first, then framing for any moved walls, headers and new openings. Drain and supply piping, gas, wiring and ductwork follow in the walls and attic, and a city inspector signs off each rough-in while the cavities still stand open. The roof deck gets its foam next, wall insulation and board go up after it, and the kitchen leads the finish trades.
In most houses, yes. From above we check which way the joists run and whether any of them splice or rest on that wall. If it bears weight, a structural engineer sizes a beam and posts, with footings below the posts when the load calls for them, all shown in the permit set. If nothing rests on it, the wall goes once its wires, pipes or duct are rerouted.
The range hood model and its airflow come first, because they set the duct size and whether make-up air is needed. Gas or induction for the cooktop follows, since it changes the panel load. Whether the roof deck gets foam decides where the furnace and water heater can stay. Cabinet layout, window sizes, floor heights from room to room and every light and switch location round out the list.
