  3. Roof PlansTerms & Definitions • Gable roof – one of the most common roof types in residential construction; constructed with two sloping sides that meet to form a ridge • Gambrel roof – a traditional shape that dates back to the colonial period; the lower level is covered with a steep roof surface, which connects into the upper roof system with a slighter pitch

  4. Roof PlansTerms & Definitions • Mansard roof – similar to a gambrel roof with the angled lower roof on all four sides rather than just two • Dutch hip roof – a combination between a hip roof and a gable roof

  6. Roof PlansTerms & Definitions • Rafter – the inclined structural member of a roof system designed to support loads • Ridge – the top of a roof where two sloping edges meet • Ridge board – the top horizontal member that rafters are aligned against to resist their downward force

  7. Roof PlansTerms & Definitions • Ceiling joist – the horizontal member of the roof which is used to resist the outward spread of the rafters and to provide a surface on which to mount the finished ceiling • Soffit – usually the underside of an overhanging cornice

  8. Roof PlansTerms & Definitions • Fascia – covers the rafter end enclosing the overhang • Lookout – a beam used to support eave loads • Valley – the internal corner formed between two intersecting roof surfaces • Hip – the exterior edge formed by two sloping roof surfaces
