Porch building

A covered porch built to the house, from the footings to the ceiling.

What this covers

A porch is a small building attached to the house: a foundation or footings, a floor framed to shed water, columns that carry a roof, and a roof that ties into the house walls or roof with proper flashing. The builder designs it to the style of the home, sizes the columns and beams for the roof load, frames the roof to drain away from the house, and finishes the ceiling, steps, railing and trim. Front porches add an entry and curb appeal; back porches extend the living space. Where the local code requires a permit, the company pulls it. Careful work shows where the porch roof meets the house.

When to call

  • A front door with only a stoop and no cover from rain.
  • A back of the house that would be used more with shade over it.
  • An old porch with a sagging roof or rotted floor that is better rebuilt than patched.

Questions people ask

Can a porch be added to any house?

Most houses, but the roof line, the window heads and the setback from the property line shape what is possible. The design stage sorts this out.

What flooring works on a covered porch?

Tongue-and-groove wood painted or stained, composite boards, or a concrete slab with tile or pavers. The choice depends on the style of the house and how exposed the floor is.

Why is the ceiling often painted blue?

It is a long tradition, especially on older homes, and the pale color brightens the shade. Any color or a natural stained wood ceiling works as well.
