Winnetka Room Additions That Keep Roof Water Moving Away
Room additions for Winnetka houses with the roof water plan drawn in from the start: flashing, gutters, downspouts and the grade at the new foundation.
A bigger roof sheds more water, and every gallon off the new slope needs a planned path away from a Winnetka foundation. Rain is infrequent on an inland lot but can arrive hard, so the gutters, downspouts and ground slope are drawn in with the rest of the plans. The addition is then ready for the first storm, and the old walls beside it are protected as well.
Roof water, from ridge to downspout
Where the new roof meets the old one and where it meets a wall, metal flashing is lapped like shingles, the upper piece over the lower. Gutters sized to the roof area feed downspouts placed to discharge away from the walls. Where a downspout cannot reach open ground, a buried drain line carries the flow to a safe outlet. A kickout flashing at the end of each roof edge that meets a wall turns water into the gutter and keeps it off the siding.
Grade and the base of the walls
Soil beside the new foundation is shaped to slope down and away from the wall, and the finished floor sits well above the surrounding ground so splash and ponding stay clear of the sill plate. Crawl space vents, if the addition has them, go above grade. A patio or walkway meeting the new wall slopes away from it, with a flexible joint at the wall. On a flat lot, shallow swales or a drain basin may be needed to move the water off to a safe low point.
Room Additions in Winnetka: what families ask
The lot answers it first. Rear and side yard setbacks, a cap on the covered share of the parcel, a floor area ceiling and a height limit all apply. Covered porches and patios can count toward coverage in some zones, so they are measured in too. The plans then show the footprint that fits.
Yes. A temporary wall seals the construction zone, and the old house stays closed up and dry beside it. Water and power shutoffs fall on days agreed beforehand, and the new roof goes on early so a rainy day does not stall the interior work.
The existing roof gives the lead. Its pitch, overhang and shingle color are carried across, and gutters and fascia continue in the same profile. Wall finish and window styles follow the house, and a threshold strip lets floors meet evenly inside.
