What is the purpose of a foundation?

Distributes the weight of the building so that the building does not experience excessive shifting or settling


What is the enemy of foundations?



What exterior system is exposed to the harshest conditions?



What are the effects of the 7 environmental conditions on roofing materials?

1. Direct sun: can destroy water proofing materials
2. Rain: Can pool on flat roofs, or build an ice dam
3. Snow: Can build up and cause the roof to collapse
4. Ice: Can crack and lift the roofing material
5. Wind: Can lift and remove roofing material
6. Dirt and pollution: Can destroy the roofing material
7. Workers walking on the roof: Possibly damaging to the UV light protection or water proofing later


What is the function of a roof deck?

Supports the roofing and prevents excessive shifting and deformation of the roofing


What are the four types of materials that roof decks are commonly made from?

1. Wood
2. Steel
3. Concrete
4. Gypsum-Concrete


Describe WOOD as a roof deck material

1. Typically a composite material, it is light and relatively inexpensive
2. A slip sheet must be installed between the deck and the roofing to prevent changes in the wood from damaging the roofing


Describe STEEL as a roof deck material

1. Strong and stiff
2. Frequently used for flat roofs


Describe CONCRETE as a roof deck material

1. Can be cast in place or preset
2. Concrete shingles are also available for pitched roofs


Describe GYPSUM-CONCRETE as a roof deck material

1. Similar to concrete, but usually lighter
2. Not strong and not suitable for buildings with high humidity interiors


What is the function of the vapor barrier in a roofing system and where should it be located?

Function: Prevents moisture from condensing in the insulation or on the surface of the deck
Location: Placed between the warm interior of the building and the insulation


What is the function of the air gap and where should it be located?

Function: Air moves through the gap, carrying heat away that has moved through the roof. Helps keep your roof cool
Location Between insulation and the roof deck


What is the difference between coal-tar pitch and asphalt?

1. Asphalt is stronger, more rigid, and doesn't require UV protection
2. Coal-tar is self-sealing but does require UV protection (layer of gravel usually)


What are the four different types of materials used on pitched roofs?

1. Composite shingles: Fiberglass reinforced asphalt shingles
2. Exotic shingles: wood, concrete, slate, tile, etc.
3. Rolled roofing: Can have same appearance as composite shingles
4. Metal: Can be rolled or shingles


What happens if a roof covered in fiberglass reinforced asphalt shingles gets too hot?

The shingles will curl and crack


When should roofs be inspected?

Twice a year, in the spring and in the fall


What should you look for in a roof inspection (inside vs. outside)

1. Inside
a. Look for holes and leaks
b. Signs of leaks include discoloration, rust, peeling, and warped material
2. Outside
a. Blocked drains
b. Damaged flashing and other terminal points
c. Pooled water, roof should be totally dry 48 hours after a rain storm
d. Problems around entries into the roof
e. Sharkfins (when water makes it through the built up roof) and alligatored asphalt (Asphalt roof starts to crack like a pothole)


What are the (5) major objectives to be accomplished by sign systems?

1. Identify property
2. Set the mood
3. Supplement marketing
4. Provide information
5. Influence guests' behavior


What are the (5) major concerns when installing large outdoor signs?

1. Must match facility
2. Must be readable by users
3. Don't block the right of way
4. Don't let landscaping hide it
5. Must meet zoning requirements


What are (8) ways to reduce landscaping and grounds maintenance costs?

1. Planting mature plants
2. Planting disease and insect resistant and drought tolerant plants
3. Plant indigenous plants
4. Use large planting beds as opposed to grass
5. Plant perennials instead of annuals
6. Place shrubs and small trees close together in beds
7. Install automatic irrigation system
8. Don't over fertilize
