c7.1 3 BASELINE ROOF FORMS
The gable, the hip, and the shed roof .
c7.2 STICK FRAMING OVERVIEW
Stick framing of these 3 roof geometries.
c7.3 TRUSS OVERVIEW
Truss roof framing for these same roofs
c7.4 TRUSS FLEXIBILITY AND LIMITATIONS
With computer assistance truss profile flexibility is vast.
c7.5 TYPICAL TRUSS PROFILES
Typical roof designs shown in profile and 3d.
c7.6 TYPICAL STICK FRAME PROFILES
Comparable roof designs shown in stick frame format.
c7.7 GRAVITY LOADING
Basics of gravity dead and live loads on roof profiles.
c7.8 WIND LOADING
Wind behavior on the roof, and resistance techniques.
c7.9 THRUST RESOLUTION
Roof rafters want to push the walls out. That is not allowed.
c7.10 COLLAR TIES, RAFTER TIES, CEILING TIES
Ties connect one rafter side to the other. Where and why?
c7.11 HEEL JOINT CONNECTION LOADING
That rafter thrust needs to be held fast at the wall.
c7.12 HEEL JOINT CONNECTION OPTIONS
Rafter connections to wall vary. So must thrust resistance.
c7.13 RIDGE CONNECTION OPTIONS
Ridge boards, ridge beams require different connections.
c7.14 RAFTER TYPE OPTIONS 1
Rafter span and length, rafter choices, rafter spacing.
c7.15 RAFTER TYPE OPTIONS 2
Span charts for the 3 common rafter options.
c7.16 HIP AND VALLEY MEMBERS AND MATH
Member options, spans, member lengths, cut heights.
c7.17 HIP AND VALLEY STRUCTURAL ROLES
The structural role of ridge, hip and valley are conditional.
7.18 GABLE ROOF LOAD DISTRIBUTIONS
Braced and ridge beamed rafter roofs distribute loads differently.
c7.19 HIP ROOF LOAD DISTRIBUTIONS
Braced and beamed hip roofs distribute loads differently.
c7.20 RIDGE BEAM AND SUPPORT POSTS
A roof beam needs carefully positioned posts.
c7.21 CONDITIONS WITH THE BRACED ROOF
The braced roof sometimes needs specific assistance.
c7.22 HIP, VALLEY SUPPORT OPTIONS
Finding post support for longer valleys and hips can help.
c7.23 HEADERS AND DORMERS IN THE ROOF
Both are structured openings in the roof.
c7.24 THERMAL ENVELOPE OPTIONS 1
Profiles explain thermal envelopes and insulation strategies.
c7.25 THERMAL ENVELOPE OPTIONS 2
Rafter and insulation depths noted per strategy, climate zone.
c7.26 CODE REQUIRED ROOF INSULATION
Code chart plus rafter and insulation depth guide.
