Truss Uplift

A home inspector may observe during a home inspection a crack in the corner of an interior ceiling made of drywall. The crack may be at the top of the wall, and it may appear very thin or narrow (a hairline crack).

Crawlspaces

Access openings must be a minimum of 18 inches high by 24 inches wide. Access to all under-floor spaces must be provided with access openings through the floor not smaller than 18 inches by 24 inches (457 mm by 610 mm).

Hydrostatic pressure refers to the pressures caused by water pushing against slabs and foundations, particularly underground concrete block or poured concrete walls of foundation and crawlspaces. Water is dense and weighs about 60 lbs. per cubic foot of volume and is therefore capable of generating immense hydrostatic pressure on anything that restricts its natural movement or flow.

The weight and pressure of the dry soil may affect and crack a foundation. There is wet soil that can exert a force against a foundation.

Collar Ties

Collar ties span between and connect opposing rafters, and they are typically placed in the top third of the attic spaces. Collar ties hold the rafters down against the ridge board and, to an extent, help prevent rafter spread. Home inspectors should take note of attics without collar ties, especially where the rafters run perpendicular to the joists. Collar ties must be at least 1x4 (nominal) and spaced not more than 4 feet on center. A lack of collar ties may allow roof rafters to separate and cause sagging of the roof's ridge and structure.www.nachi.org

A brick wall is not necessarily considered to be waterproof. Water can penetrate through a masonry crack that is hairline or as small as 1/100th of an inch (0.3 mm). And masonry exterior-covering materials (siding) is porous and can absorb moisture during a weather event.

inspectors should look for and note:
