Course Description

Introduces the theory and practice of roof framing. Includes calculations to determine rafter lengths for slopes and spans. Addresses erecting and installing trusses and techniques for rafter installation. Prerequisites: MTH 98 or placement into MTH 65; placement into IRW 115 or WR 115. Audit Available.

Course Outcomes

Upon successful completion of this course, students will be able to:

  1. Demonstrate safe practices associated with Construction industry.
  2. Apply math formulas to calculate trusses and rafters construction.
  3. Classify and describe various roof types.
  4. Follow local building codes for roof construction.
  5. Analyze and build a functioning structural roof system.
  6. Describe the framing methods for different types of roofs.

Suggested Outcome Assessment Strategies

The determination of assessment strategies is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: writings (journals, self-reflections, pre writing exercises, essays), quizzes, tests, midterm and final exams, group projects, presentations (in person, videos, etc), self-assessments, experimentations, lab reports, peer critiques, responses (to texts, podcasts, videos, films, etc), student generated questions, Escape Room, interviews, and/or portfolios.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Course Content

Outcome #1: Demonstrate safe practices associated with Construction industry.

  • Cleanliness of work area
  • Recognizing margins for specific tool safety – Red Zone
    • Saws
    • Drills
    • Hand tools
  • Maintaining tools in proper working condition
  • Safety rules of thumb:
    • Don’t force tools to do something they are not meant to do
    • Be present when using tools
    • Stay alert to what is going on around you

Outcome #2: Apply math formulas to calculate trusses and rafters construction.

  • Understand the purpose of roof trusses and rafters
  • Identify common truss parts, including plates and connectors
  • Calculate truss load based on number of members and nodes
  • Create a scale model of a truss pattern
  • Describe installation of trusses and rafters

Outcome #3: Classify and describe various roof types.

  • Identify and apply elements of gable roof
  • Identify and apply elements of hip roof
  • Identify and apply elements of an intersecting roof
  • Identify and apply elements of a truss roof

Outcome #4: Follow local building codes for roof construction.

  • Identify appropriate codes that apply to roof construction
  • Read and interpret codes
  • Follow and apply code standards

Outcome #5: Analyze and build a functioning structural roof system.

  • Determine which roof type is right for the project – Pros and cons
  • Apply principles of roof layout
  • Determine roof pitch and unit rise
  • Identify span and run

Outcome #6: Describe the framing methods for different types of roofs.

  • Consider load issues with flat roofs
  • Identify angles used for upper roof surfaces and lower roof surfaces
  • Recognize special framing problems that may occur, and identify possible solutions
