About This Quiz
Do you know what you might want to use a truss for, or which materials are the most effective forms of insulation for small spaces? Think you know the code related to fire-rated drywall, or what size egress window you need in a basement bedroom? Take our quiz to test your home construction knowledge and find out if a career in the building field is right for you!
Many men and women who end up building homes for a living do so to take advantage of certain natural skills and interests, including experience with carpentry or tools, a desire to work with their hands and a passion for working outside of the boring office environment. Yet many quickly learn that home construction requires so much more than the ability to actually construct things or puzzle out a tricky installation.
A good home builder is essentially a jack of all trades, and must understand the basics about every single system required in a home - from plumbing and electrical to heating and cooling to structural support, humidity and moisture control, and everything in between. They must understand which type of foundation or framing works best on a specific piece of property, which insulation will keep occupants comfortable all year long, and whether alternative materials could work better than standard stick framing in some cases.
Yet for all that knowledge and hard work, the home builder is rewarded with watching his or her creations come to life in the form of a house, which will one day house a family. Thing you've got what it takes to master this industry? Prove it with this quiz!
What word do construction pros use to describe ground level?
Masonry
Grade
Contractors use the term grade when referring to ground level. That means footers are installed below grade - underground - while all the windows in the house are above grade. The term grading also refers to the process of bringing the earth on the site to the desired slope or level before building a home. Grading is the first step in the home construction process.

Which of these is the most common roofing material used on homes in the U.S.?
Metal
Clay
Asphalt
There's a reason asphalt shingles are the most commonly-used roofing material for homes - they're among the cheapest roof finishes available, but still last for decades when properly installed and maintained. Unlike clay tiles and metal roofs, they are also fairly easy to install.
Wood

What material is typically installed directly over the exterior wall framing of a house?
Siding
Trusses
Sheathing
After framing up a home, the next step in construction involves installing wall sheathing. This consists of screwing sheets of plywood or similar sheet wood over the framed walls to add structural support. The sheathing is then covered with building paper or some form of moisture barrier.
Forming

Which material is the most common siding used on U.S. homes?
Vinyl
Vinyl siding is the most popular siding finish for American homes. According to the U.S. Census Survey of Housing Materials, around 27 percent of all homes are covered in vinyl. Many builders and homeowners choose this finish because it is affordable, easy to work with, and fairly durable and long-lasting.

Which of these areas always requires fire-rated drywall, according to the National Residential Code?
Garage

10 to 20 gallons
20 to 30 gallons
50 to 60 gallons
No modern house is complete without plenty of hot water for showers, laundry and other functions.

Which of these materials is the most effective insulator?
Fiberglass
Spray foam
Insulation reduces thermal transfer between the interior and exterior of the home. Materials with a higher R-value have higher thermal resistance, and are more effective insulators. Spray foam is the most effective of these materials, with an R-value of 5.9 per inch, better than that of fiberglass batts, loose fill fiberglass, cellulose and polystyrene sheets, according to the U.S. Department of Energy.
Cellulose
Polystyrene sheets

Foundation
Successful home builders know that there is no getting around local inspection requirements.
