A rafter is a sloped structural framing member that helps form the shape of a roof. Rafters support the roof decking, which then supports underlayment, shingles, flashing, and other roof materials.
Why It Matters
Rafters are part of the structure beneath the roof system. If rafters are damaged, sagging, improperly altered, or not providing sound support, the roof surface above them can be affected.
Common Problems
Common problems include sagging rafters, water damage near long-term leaks, improper cuts or modifications, poor ventilation around the roof structure, and confusion between cosmetic roof issues and structural framing concerns.
Building Codes & Industry Standards
Rafters need to be sized, spaced, connected, and supported according to the home design and applicable building code requirements. Structural changes should not be guessed at in the field.
Exterior Echelon Notes
Exterior Echelon looks for signs that the roof structure is supporting the roof system properly. If a framing concern appears to be structural, it should be evaluated carefully before roofing materials are installed over it.
