Siding is a key part to the exterior inspection. Because siding is highly visible, its condition is a big factor in the salability of the house. Siding is designed to protect the house from rain, snow, wind, cold and/or heat. When it cannot keep the elements out, energy bills sky-rocket and the house structure is exposed to decay.
A qualified property inspector will inspect your home's siding as a part of a general home inspection. An inspector will first note the type of siding on your home (brick, vinyl, stucco, exterior plywood, etc.). A professional will then check the condition of the exterior surface, including the presence/absence of any cracks, blisters, chips, evidence of moisture intrusion and improper installation practices.
Each siding type and style reacts differently to weather conditions and age. A professional will note any areas in need of maintenance and recommend repairs.
