Ibc Flashing Roof
Fastening and do not address underlayment flashing and other roof covering components.
Ibc flashing roof. Weep screeds are common and code required ibc section 2512 for cement plaster over framed walls. Ibc 2012 s section 1510 1 general indi cates materials and application methods used for re covering or replacing existing roof systems must comply with the same re quirements as new roof systems except reroofing projects need not comply with the code s minimum 12 slope require ment for roofs that provide positive drainage. Where flashing is of metal the metal shall be corrosion resistant with a thickness of not less than 0 019 inch 0 5 mm no. Test standards such as astm d7158 are available to provide performance metrics for asphalt shingles.
The weep screed may be made for galvanized metal plastics or aluminum. Flashing shall be installed at wall and roof intersections at gutters wherever there is a change in roof slope or direction and around roof openings. R903 2 2 crickets and saddles. Where flashing is of metal the metal shall be corrosion resistant with a thickness of not less than 0 019 inch 0 483 mm no.
The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. One of the most critical elements of the roof system is the flashing component. A flashing shall be installed to divert the water away from where the eave of a sloped roof intersects a vertical sidewall. The new icc 600 standard is the residential design standard for hurricane resistant construction replacing sstd 10 and to reference the astm d7158 standard.
Typically they should be set at or below the foundation plate line to allow moisture to exit or weep out and to prevent ground moisture from wicking up. The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process. The minimum required thermal resistance varies depending on insulation placement relative to other materials. The ibc includes the principle that flashing shall be installed to prevent moisture from entering the wall or to redirect that moisture to the exterior.
Ibc dictates acceptable placement and composition of roofing materials in chapter 15 but describes required thermal efficiency of the roof in chapter 13 which references the international energy conservation code iecc.
