A porch is an extension with a roof on the exterior of the residence.  Porches differ in design and purpose from decks and landings. Railings, posts and other decorative elements provide character to a house, but they should be examined to ensure that they are free from deterioration and will provide the necessary structural support.

Porches that are open to the weather should have floors that slope away from the residence. The slope should be incorporated into the design so that water drains easily off of the porch. Entry must be gained underneath the porch area to examine the supporting structure and to be sure that the posts and columns are acceptable. Wood elements should have a separation from the ground or soil area. Brick and masonry components should be plumb, with their mortar joints in good condition.

Porches may also be an entrance to the residence. Wood stairways leading from the ground to the porch should be examined from underneath as well as from the top to ensure that the stringers and other supporting members are not deteriorating. Handrails should be examined to ensure that they are properly fastened to the supporting structures. If the stairway is masonry or concrete, examine it for cracking, settling, or tripping hazards.
