OIC Inspection Techniques & Procedures 3

Question 1

When walking a roof during an inspection, an inspector feels the decking deflect underfoot. What does this most likely indicate?

Accepted Answer

Rotten or damaged sheathing below the shingles

Answer

Soft or spongy areas underfoot on a roof typically indicate deteriorated, wet, or rotten roof sheathing that requires further evaluation.

Question 2

Which of the following best describes the correct procedure for operating windows during a home inspection?

Accepted Answer

Operate all accessible windows to check for ease of operation, locking hardware, and condition

Answer

Oregon inspection standards require that inspectors operate all accessible windows to evaluate their function, hardware, and condition.

Question 3

An inspector finds the main electrical panel has double-tapped breakers (two wires on one breaker). This is significant because:

Accepted Answer

It can cause overheating and tripping issues unless the breaker is rated for multiple conductors

Answer

Most breakers are rated for a single conductor; double-tapping can cause loose connections, overheating, and nuisance tripping unless the breaker is specifically listed for multiple conductors.

Question 4

What is the inspector's primary concern when examining chimney flashing?

Accepted Answer

Whether the flashing properly seals the joint between the chimney and roof to prevent water intrusion

Answer

Flashing must create a watertight seal at the chimney-roof junction; failed flashing is one of the most common causes of roof-related water damage.

Question 5

During plumbing inspection, an inspector tests water pressure and finds it is 100 psi. What should be noted in the report?

Accepted Answer

Pressure exceeds the recommended maximum of 80 psi and a pressure-reducing valve should be evaluated

Answer

Normal residential water pressure should be 40–80 psi; readings above 80 psi can stress pipes and fixtures, warranting a PRV evaluation.
