Underwriters Laboratories (UL) External Fire Ratings
All regional building codes and most local building code officials require that roofing systems meet minimum performance
requirements when exposed to external fire sources. The accepted method for measuring external fire resistance is ASTM
E-108. This test standard, and closely related standards such as Underwriters Laboratories UL-790 and Uniform Building
Code 15-2, is used to determine the ability of a roof system to hinder the horizontal spread or vertical penetration of an
external fire source. In accordance with these standards, all classified roof covering assemblies fall into one of the three
following categories.
•
•
•

CLASS A: Includes roof coverings which are effective against severe fire exposures
CLASS B: Includes roof coverings which are effective against moderate fire exposures
CLASS C: Includes roof coverings which are effective against light fire exposures

Noncombustible Roof Decks (NC): Steel, Concrete, Poured Gypsum – require testing for horizontal spread of flame.
Combustible Roof Decks (C): Wood, Plywood, Tectum – require testing for both horizontal spread and vertical penetration
of flame.
The following information has been referenced from the UL Online Certification Directory document:
TGFU.GuideInfo
Certified gypsum wallboard, any thickness, may be included in any roofing system without adversely affecting the
certification. Insulations may be attached to the deck with fasteners, hot mopping asphalt or certified adhesive.
Certified insulated systems may be installed over existing certified insulated systems when:
1) the new system is certified for use with the existing roof insulation type (glass fiber, perlite, wood fiber, foamed plastic,
etc.)
2) the total thickness of insulation in both systems does not exceed the maximum specified for the new system being
applied.

MAINTENANCE AND REPAIR SYSTEMS
These roofing systems are composed of various types of roofing applications which are specifically limited for installation
(recover) over existing roofing systems as specified. These systems may not meet certification requirements without being
used over existing systems. Recovering may also be accomplished with certified new construction roofing systems where
compatibility has been determined by test, by empirical data or by known performance properties of similar materials to the
test methods. The following guidelines are provided to assist Authorities Having Jurisdiction in determining the suitability of
a new construction roofing system as a recover system.
Noncombustible Deck Construction:
1. Insulated roof systems may be utilized over any type of existing roof system and maintain its new construction rating
when the roof deck is noncombustible.
2. Insulated multiple-layered hot mopped, cold application or modified bitumen membrane new construction systems
with a base ply of Type G1 or Type G2 may be used over any existing roof system and maintain its new construction
rating when the roof deck is noncombustible. The insulation may be omitted from the recover system.
3. Uninsulated multiple-layered hot mopped, cold application or modified bitumen membrane new construction
systems with a base ply of Type G1 or Type G2 may be used over any existing uninsulated roof system and maintain
its new construction rating when the roof deck is noncombustible.
Combustible Deck Construction:
1. Insulated roof systems certified for use over combustible deck can be used over any type of existing roof system
and maintain its new construction rating.
2. Insulated roof systems certified for use over noncombustible deck may be used over any type of Class A, B or C
existing roof systems. The resultant Class will be the lesser rating of the existing system or the new construction
(recover) system.
3. Uninsulated multiple-layered hot mopped, cold application or modified bitumen membrane new construction
systems with a base ply of Type G1 or Type G2 may be used over any existing uninsulated roof system and maintain
its new construction rating.

The class of roof covering required by each regional building code depends upon many factors, including the use and
location of the building and the type of construction. The local building authority should always be consulted as to what the
roofing assembly classification will need to be for each roofing project.
It should be noted that these classifications apply to roofing assemblies, and NOT the roofing membrane. A roofing
membrane that is classified as part of a Class A assembly when installed over a particular insulation may not qualify as part
of a Class A assembly with another insulation.
The “UL Item Number” in the following listings has been added as a service to those who have the UL Building Materials
Directory. It identifies the UL listing from which our Code Approval Guide listing derives (e.g., “A,FA,23” means Class A,
Fully Adhered, item number 23; “B,MA,04” means Class B, Mechanically Attached, item number 04, etc.).

General Notations
•

PLEASE NOTE: Not all UL-rated assemblies that use Firestone roofing products are eligible for the Firestone Red

UL Internal Fire Ratings
To determine the resistance of a building to internal sources of fire, Underwriters Laboratories has conducted extensive
testing and classification of wall, floor/ceiling and roof/ceiling assemblies. UL classified assemblies are rated according to
the time in hours the assembly will contain a fire and still maintain structural integrity. Testing is conducted in accordance
with UL Standard 263 (ASTM E-119), which is recognized by all major building codes.
Roof/Ceiling Assemblies are listed in the UL Fire Resistance Directory - Vol. 1 under the prefix “P” and are classified by
hourly fire rating according to the type of protection used to contain a fire:
Assembly

Protection Used

P000 – P099
P200 – P299
P400 – P499
P500 – P599
P600 – P699
P700 – P799
P800 – P899
P900 – P999

Concealed grid suspended ceiling
Exposed grid suspended ceiling
Metal lathe (plaster) ceiling
Gypsum board ceiling
Miscellaneous fireproofing
Spray-Applied Resistive Material
Spray-Applied Resistive Material
Unprotected concrete or composite decks

It should be noted that the roof membrane forms only a small part of the total roof/ceiling assembly. For a structure to
qualify for a “P” Assembly or Roof Deck Construction, all materials used to construct the assembly (including roof decking,
ceiling materials, light fixtures, duct work and structural support members) must be UL classified and installed as described
in the appropriate UL Directories.
The insulations listed with each of the following “P” Assemblies are not, in most cases, the only UL accepted insulations for
that assembly. Consult the UL Fire Resistance Directory - Vol. 1 for “P” Assembly information and the UL Roofing Materials
and Systems Directory for Roof Deck Construction information, or call Firestone Technical Services for additional accepted
insulations.
UL has indicated on page 8 of the 2008 Fire Resistance Directory - Vol. 1 that "Class A, B or C roof coverings consisting of
hot mopped or cold applied bituminous materials or a roof covering material classified under 'Roofing Membranes' (CHCI)
may be applied directly to the concrete or wood surface of floor designs being used as roofs without a reduction of fire
resistance ratings." They further state on page 8 that "Roof insulation is to be carefully controlled relative to manufacturer,
type and thickness as specified. Less than the specified thickness could result in higher temperatures on the roof covering
while a greater thickness of insulation could cause earlier structural failure. Classified polystyrene insulation, with a density
of 5 pcf or less, may be placed on concrete floors or structural concrete roofs without reducing the assembly rating. When
polyisocyanurate insulation is used over concrete in D 900 Series Designs, the unrestrained beam rating shall be increased
by a minimum of ½ hour."
Roof Deck Constructions are listed in the UL Roofing Materials and Systems Directory and are rated according to the
interior flame spread of the assembly as compared to the flame spread of a typical built-up roof installed over a metal deck
(UL 1256). Roof Deck Constructions may also be classified according to wind uplift performance. The fire rating of a UL
Roof Deck Construction is similar to the Factory Mutual Class I internal fire (calorimeter) rating and they are deemed
equivalent by the Model Building Code Agencies.
UL Roof Deck Constructions and “P” Assemblies
Deck Constructions (Tested in accordance to UL 1256)
Firestone UltraPly TPO 96/120 roofing systems are classified for use in the following Deck Construction:
1, 2, 9, 14, 120, 123, 158, 200, 219, 237, 260, 276, 289, 292, 325, 374, 411, 412, 413, 419, 421, 440, 441, 444, 457, and
458. Consult Roof Deck Constructions (TGKX) in the UL Roofing Materials and Systems Directory, your regional technical
coordinator or the Firestone Codes Department for an acceptable insulation for use in these constructions.
“P” Assemblies (Designs)
Firestone TPO 96/120 roofing systems are classified for use in the following hourly roof / ceiling designs. Ballasted,
adhered or mechanically attached systems with or without optional wood fiber or mineral board insulation for use
in Design numbers:
P215, P216, P225, P227, P230, P231, P242, P246, P251, P259, P405, P406, P407, P410, P508, P510, P511,P512,P51

NOTE: The accepted insulation must be used in a UL Class A, B or C rated roofing assembly. UL acceptable system (e.g.,
adhering EPDM to Perlite or Fiberglass) listed for "P" design may not be approved for installation and warranty by Firestone.
Contact Firestone Specifications and/or your Firestone Regional Technical Coordinator concerning acceptance.
Factory Mutual General Information
Factory Mutual Class 1 Approvals cover a wide range of testing of roofing products, including tests for fire resistance,
corrosion resistance, fuel contribution and hail damage, Factory Mutual Approvals are known best for the uplift resistance,
1-60, 1-90, etc. afforded by an FM Approved roofing assembly:
•
•
•

FM 1-60 assemblies have been tested to withstand 60 psf air pressure applied for a period of one minute as well
as one minute at the 30 and 45 psf levels.
FM 1-90 assemblies have been tested to withstand 90 psf air pressure applied for a period of one minute as well
as one minute at the 30, 45, 60 and 75 psf levels.
Higher uplift ratings are possible based on the deck type and its attachment, fastener density and row spacing
where applicable.

When Factory Mutual 1-60 or 1-90 uplift ratings are specified, additional insulation attachment and reduced perimeter and
corner batten (in-seam plate or batten for Reinforced Systems) spacing will/may be required. Consult the current edition of
Factory Mutual Loss Prevention Data Sheets 1-28 and 1-29 for instructions for determining the required corner and
perimeter dimensions and reduced spacing and increased fastener densities.
Ground Roughness Definitions
The descriptions below are based on information in ASCE 7. While information on this subject in the body of that standard
is relatively brief, the designer must read the considerable additional information provided in the related commentary section
of that document, particularly when then exposure is not obvious.
For Exposure Category B to be used:
A. The exposing terrain should include urban and suburban areas, wooded areas, or other terrain with numerous
closely spaced obstructions having the size of single-family dwellings or larger.
B. Use of this exposure category should be limited to those areas for which the above terrain prevails in all directions
for a distance of at least 2600′ (800 m) or 20 times the height of the building or other structure, whichever is greater.
C. Limited openings in this terrain, such as small parking lots, roads, road intersections, playing fields,
underdeveloped lots, and tree clearings can be tolerated. For openings that exceed 600′ (180 m) in total length
measured radially from the building and 165′ [50 m] in width, use surface roughness exposure C.
D. For buildings whose height is less than or equal to 30′ (9.1 m), the prevailing exposure B distance may be reduced
to 1500′ (460 m).
E. In cases where the difference between exposures B and C is not obvious, use exposure C.
Exposure Category C
NOTE: In cases where the difference between exposure B and C is not obvious, use exposure C.
For Exposure Category C to be used:
A. The exposing terrain should be open with scattered obstructions having heights generally less than 30′ (9 m), such
as flat, open country and grasslands, and in all cases where exposures B and D do not apply.
B. This also includes where surface roughness exposure B terrain is interrupted by clearings (parking lots, wide roads,
road intersections, playing fields, underdeveloped lots, tree clearings, etc.) of greater than 600′ (180 m) in total
length measured radially from the building and exceeding 165′ (50 m) in width.
Exposure Category D
NOTE: Some examples of D exposures include inland waterways, the Great Lakes, and coastal areas. See fig. 3.2.2.3 in
FM Global LPDA 1-28 for examples of Exposure D requirements. For Exposure Category D to be used in determining the
design wind pressure, all the following must be met:
A. The terrain upwind of the structure must be flat, unobstructed areas or water surfaces including smooth mud flats,
salt flats, and unbroken ice and is present in the upwind direction for a distance greater than approximately 5000′
(1500 m) or 20 times the building height, and
B. The building must be within the greater of 600′ (180 m) or 20 times the building or structure height from the terrain
(see Fig. 3.2.2.3), even if the terrain between the building and the terrain described in A. above would otherwise
be considered Category B or C.

Ballasted Systems
Factory Mutual tests and rates only fully adhered and mechanically attached systems; Factory Mutual does accept the use
of Ballasted Roof Systems on a job-to-job basis for FM insured clients. According to Mr. Edward J. Ward, Construction
Standards Manager for Factory Mutual Research, “... the Factory Mutual system windstorm loss experience has been
extremely favorable for Single-Ply ballasted roof systems. When these roofs are installed in accordance with (Factory
Mutual) Loss Prevention Data Sheet 1-29, they are equally acceptable to Factory Mutual approved roofs.”
General Notations
PLEASE NOTE: Not all FM-rated assemblies that use Firestone roofing products are eligible for the Firestone Red
Shield, Red Shield Medallion, or Platinum Warranty. The Firestone standards, guidelines, and specifications
regarding roofing system components and attachment for the warranty desired must be followed.
RoofNav® assemblies are summarized in the following tables; however, an assembly search should be conducted to
confirm the attachment rates and requirements set for in the approval number. In all occasions, should a discrepancy occur
between this guide and RoofNav, the published information located in the approval at www.roofnav.com should be adhered
and utilized.
Additionally, please be aware that the following assemblies typically are in reference to the field of the roof rating and
attachment. Please refer to FM Global Loss Prevention Data Sheet 1-28 and 1-29 to determine the requirements for
additional fastening requirements in the perimeter and corner.
In all cases, when the project is Factory Mutual insured, please consult the FM agent assigned to the review of the project
to ensure compliance.
The below stated assemblies may not be suitable for a Firestone Warranty. Prior to installation, contact a Firestone
Representative for approval of assembly for warranty purposes.
It is acceptable to use multiple layers of FM Approved insulation, mechanically secured through all layers, provided all
the following are true:
• All layers are the same insulation;
• The total insulation thickness is not greater than the maximum FM Approved thickness of the insulation;
• The mechanical fastening and wind uplift rating are per the FM Approval of the top layer; and,
• The roof cover/insulation/fastener combination is FM Approved.
**Water Based Bonding Adhesive-P (WBBA-P) is the equivalent to Water Based Bonding Adhesive-S (WBBA-S)**

Prescriptive Enhancement Options: Perimeter and Corner
For all deck types, where roof covers are adhered to some combination of mechanically fastened insulation, cover board,
or thermal barriers, prescriptive enhancements may be used for securement of the perimeter and corner areas, if one of the
conditions below applies:
•
•
•

The building is in a non-hurricane prone region where the design wind speed does not exceed 90 mph and the roof
height does not exceed 75 ft (23 m). Note the roof height is limited to 30 ft (9.1 m) if the building is located in surface
roughness exposure D (see DS 1-28) and the building is partially enclosed.
The recommended field of roof rating needed per DS 1-28 does not exceed Class 1-75 (3.6 kPa).
The building is located in a non-hurricane prone area and the recommended field of the roof rating per Datasheet
1-28 does not exceed Class 1-90.

For any of the three conditions above, increase the number of fasteners per board over the FM Approved field of the roof
spacing by the following:
•
•
•

50% minimum in the roof perimeter, but at least one fastener per 2 ft². (1 per 0.19 m²). It is not necessary to install
fasteners closer than one per 1 ft² (1 per 0.09 m²).
One fastener per 1 ft² (1 per 0.09 m²) in corner areas.
Round up to the next whole number of fasteners, if necessary.

You must verify the included assemblies in the charts below with the associated Firm’s (UL, FM, etc.).
Not all the information included in the RoofNav assemblies will be listed in the charts below.
You must verify that all assemblies meet Firestone Building Products warranty requirements with the
associated regions technical team.
NOTE: You must verify if any portion of the assembly needs primer. Most self adhering materials require
primer to be used.
