Section RR1525
HIGH VELOCITY HURRICANE ZONES REQUIRED OWNERS NOTIFICATION
FOR ROOFING CONSIDERATIONS
§RR1525 Scope. As it pertains to this section, it is the responsibility of the roofing contractor to provide the
owner with the required roofing permit, and to explain to the owner the content of this section. The provisions of
Chapter 15 of the Florida Building Code, Building govern the minimum requirements and standards of the industry
for roofing system installations. Additionally, the following items should be addressed as part of the agreement
between the owner and the contractor. The owner's initial in the designated space indicates that the item has been
explained.
1. Aesthetics-Workmanship: The workmanship provisions of Chapter 15 (High Velocity Hurricane
Zone) are for the purpose of providing that the roofing system meets the wind resistance and water intrusion
performance standards. Aesthetics (appearance) are not a consideration with respect to workmanship provisions.
Aesthetic issues such as color or architectural appearance, that are not part of a zoning code, should be
addressed as part of the agreement between the owner and the contractor.
2. Renailing Wood Decks: When replacing roofing, the existing wood roof deck may have to be
renailed in accordance with the current provisions of Chapter 16 (High Velocity Hurricane Zones) of the Florida
Building Code, Building. (The roof deck is usually concealed prior to removing the existing roof system).
3. Common Roofs: Common roofs are those which have no visible delineation between neighboring
units (i.e., townhouses, condominiums, etc.). In buildings with common roofs, the roofing contractor and/or owner
should notify the occupants of adjacent units of roofing work to be performed.
4. Exposed ceilings: Exposed, open beam ceilings are where the underside of the roof decking can be
viewed from below. The owner may wish to maintain the architectural appearance; therefore, roofing nail
penetrations of the underside of the decking may not be acceptable. The provides the option of maintaining this
appearance.
5. Ponding Water: The current roof system and/or deck of the building may not drain well and may
cause water to pond (accumulate) in low-lying areas of the roof. Ponding can be an indication of structural distress
and may require the review of a professional structural engineer. Ponding may shorten the life expectancy and
performance of the new roofing system. Ponding conditions may not be evident until the original roofing system is
removed. Ponding conditions should be corrected.
6. Overflow Scuppers (wall outlets): It is required that rainwater flow off so that the roof is not
overloaded from a buildup of water. Perimeter/edge walls or other roof extensions may block this discharge if
overflow scuppers (wall outlets) are not provided. It may be necessary to install overflow scuppers in accordance
with the requirements of Chapter 15 and 16 herein and the Florida Building Code, Plumbing.
7. Ventilation: Most roof structures should have some ability to vent natural airflow through the interior
of the structural assembly (the building itself). The existing amount of attic ventilation shall not be reduced. It may
be beneficial to consider additional venting which can result in extending the service life of the roof.

For Moment based tile systems, choose either Method 1 or 2. Compare the values for M
r
with the values from M
f
. If the M
f
values are greater than or
equal to the M
r
values, for each area of the roof, then the tile attachment method is acceptable.

For Uplift based tile systems use Method 3. Compared the values for F’with the values for Fr. If the F’values are greater than or equal to the Fr values,
for each area of the roof, then the tile attachment method is acceptable.
