CCS Chimney Inspection & Assessment 3

Question 1

When a chimney inspection reveals that the mortar joints are recessed more than 3/4 inch, what corrective action is typically recommended?

Accepted Answer

Repointing (tuckpointing) the joints

Answer

When mortar joints are recessed more than 3/4 inch, repointing (tuckpointing) is required to restore the mortar to the proper depth and prevent further water infiltration.

Question 2

A chimney inspector notices that the flashing at the roofline has pulled away from the masonry. What is the most significant risk this creates?

Accepted Answer

Water infiltration into the home structure

Answer

Improperly sealed or separated flashing allows water to run directly into the joint between the chimney and the roof, causing serious structural damage and leaks.

Question 3

Under NFPA 211, what clearance is typically required between a single-wall metal connector pipe and combustible materials?

Accepted Answer

18 inches

Answer

NFPA 211 requires a minimum of 18 inches clearance between a single-wall metal connector pipe and combustible materials to prevent ignition.

Question 4

During a Level 1 inspection, the inspector finds that the damper plate is warped and will not fully close. What should be documented?

Accepted Answer

The damper deficiency as a safety concern affecting energy efficiency and draft control

Answer

A warped damper that won't fully close is a deficiency that allows unconditioned air to enter or escape, reduces draft control, and should be documented as a safety and efficiency concern.

Question 5

What is the recommended minimum height a chimney should extend above the highest point of a roof within 10 feet (measured horizontally)?

Accepted Answer

2 feet

Answer

NFPA 211 and standard practice require chimneys to extend at least 2 feet above any part of the roof within 10 horizontal feet to ensure proper draft and prevent downdrafts.
