Update to underlayment requirements in the
7
th
Edition (2020) FBC-Building and FBC-
Residential:
A sealed roof deck (SRD) is required.
where felt underlayment is used, it must be
30# or equivalent (ASTM D 226 Type II,
ASTM D4869 Types III or IV)
installation techniques such as number of
plies, lapping, and fastener spacing has been
strengthened
For concrete and clay roof tile,
underlayment is required to be in
accordance with the FRSA/TRI Florida High
Wind Concrete and Clay Roof Tile
Installation Manual, 6
th
edition.
For asphalt, metal, mineral surfaced, slate and
slate- type roof coverings, there are essentially
three options for creating a sealed roof deck that
vary a bit depending on the type of roof covering.
A summary of the three options available is as
follows:
Option #1 a self-adhering polymer-modified
bitumen underlayment complying with ASTM
D1970 applied over the entire roof.
Option #2 a minimum 4-inch wide strip of self-
adhering polymer-modified bitumen complying with
ASTM D1970 or a minimum 3 ¾ - inch wide strip of
self- adhering flexible flashing tape complying with
AAMA 711, applied over all joints in the roof decking. A
felt underlayment complying with ASTM D226 Type II,
ASTM D4869 Type III or IV,
or ASTM D6757, or a synthetic underlayment meeting
the performance requirements specified, is required to
be applied over the strips/tape over the entire roof.
(See Table 1507.1.1.1 of the FBCB or Table R905.1.1.1
of the FBCR for fastener type and spacing).
Option #3 two layers of felt underlayment comply
ASTM D226 Type II or ASTM D4869

(3" × 0.120") nails. The RSRS designation indicates the
fastener is a ring shank roof sheathing nail.
