1) Detective Plumbing 

Defective plumbing can manifest itself in two different ways: leaking and clogging. A visual inspection can detect leaking, and an inspector will gauge water pressure by turning on all faucets in the highest bathroom and then flushing the toilet. 

If you hear the sound of running water, it indicates that the pipes are undersized. If the water appears dirty when first turned on the faucet, this is a good indication that the pipes are rusting, which can result in severe water quality problems. 

2) Inadequate Wiring & Electrical 

Your home should have a minimum of 100 amps service, and this should be clearly marked. Wire should be copper or aluminum. Home inspectors will look at octopus plugs as indicative of inadequate circuits and potential fire hazard. 

3) Roofing Problems

Water leakage through the roof can occur from a variety of reasons such as physical deterioration of the asphalt shingles (e.g curling or splitting) or mechanical damage from a wind storm. When gutters leak and down spouts allow water to run down and through the exteriors walls. This external problems becomes a major internal one. 

4) Poor Heating and Cooling Systems

Insufficient insulation, and an inadequate or a poorly functioning heating system, are the most common causes of poor heating. While an adequately clean furnace, without rust on the heat exchanger, usually has life left in it, an inspector will be asking and checking to see if your furnace is over its typical lifespan of 15-25 yrs. For a forced air gas system, a heat exchanger will come under particular scrutiny since one that is cracked can emit deadly carbon monoxide into the home. These heat exchangers must be replaced if damaged- they can be repaired.
