Q

Underground terminations usually connect to one of three system types. Name the 3 types of systems:

A

On-site drainage: The gutters connect to subterranean piping that simply takes the run-off to a low area on the property, well away from the foundation. and discharges it to the ground,

Connection to foundation drains: In these systems downspouts connect via vertical drains to the home’s foundation or drain tile system.

French drains and dry-wells: A pit or channel is dug and lined with a membrane, and normally filled with crushed stone.

Q

What causes a Roof to have a wavy appearance?

A

rafters or trusses set too far apart;

roof sheathing that’s too thin;

moisture-damaged sheathing;

sheathing that’s fitted too closely together; and/or

sheathing that’s missing H-clips.

21
Q

Why should an inspector also pay close attention to the wall structures when inspecting the roof structure from outside:

A

The inspector may possibly observe signs of the walls bowing out, or the soffits pulling away from the tops of the walls. A condition called rafter spread.

22
Q

Define Rafter Spread?

A

A condition where the weight of the roof has pushed the roof rafters outward. This results in a separation of the roof structure from the walls, and pushing the top of the walls outward

23
Q

The horizontal board enclosing the ends of the rafter projections (or tails) is normally referred to as the _____ board.
fascia
cornice
soffit

A

FASCIA

24
Q

Roof sheathing should be installed ___________ to the rafters.
vertical
parallel
perpendicular

A

PERPENDICULAR

25
Q

The distance that should separate the siding from the roof’s surface is __________.
less than 1 inch
2 to 4 inches
1 to 2 inches

A

1 TO 2 INCHES

26
Q

A soffit that is attached directly to the underside of the rafter tails is called a(n) _______ soffit.
open
box
enclosed

A

ENCLOSED.

27
Q

The clips that are required between many sheathing panels are called ___-clips.
L

28
Q

Drip edge flashing should be installed ____________.
over the roofing paper/felt along the eave edge
under the roofing paper/felt along the rake edge
over the roofing paper/felt along the rake edge

A

over the roofing paper/felt along the rake edge

29
Q

If a gap exists between the wall and soffit, it may indicate __________.

moisture in the soffit
rafter sag or spread
blocked gutters

A

RAFTER SAG OR SPREAD

30
Q

Name the different types of roof coverings?

A

asphalt shingle;

tile, slate; clay tile; concrete tile; & asbestos cement tile.

wood and shake shingle

roll roofing;

built-up roofing;

membrane roofing;

metal roofing systems,
standing seam systems; and
metal oddities (shingle, sheet, corrugated).

31
Q

What is a Gable Style Roof?

A

They have two slopes and the ridge extends the length of the home. The lower, level edges of the roof are called the “eaves,” and the sloped edges are called the “gables” or “rakes.”

32
Q

How many Hip Style Roofs are there?

A

There are two types of hip roofs; Basic and Full.

33
Q

What is a Basic Hip Roof?

A

The basic hip roof has a level ridge that doesn’t extend all the way to the exterior walls. Instead, hip rafters slope diagonally down to each corner.

34
Q

What is a FULL Hip Roof?

A

Full hip roofs have no real ridge. The hip rafters all meet to form a point at the peak of the roof.

35
Q

Name other less common Roofs?

A

Clerestory, Cupola, Conical Roofs, Bonnet, Butterfly, Flat, Gambrel, Mansard, Shed,

36
Q

What is a Dormer?

A

Dormers are projections built into the slope of a roof. Inspection concerns are valleys, headwall and sidewall flashing.

37
Q

Regardless of roofing materials used, What variables are all roofs susceptible too?

A 
weather;
impact damage; 
environmental conditions;
orientation;
ventilation;
insulation;
structural issues; and 
installation defects.
38
Q

What are some of the factors which can influence the Life expectancy of a Roof?
