o F. brittleness temperature. 
 
7.  Provide 60 mil uncured EPDM flashings and rubber pipe penetration boots. 
 
8.  Produced and recommended specifically by manufacturer for use in a roofing 
system. 
 
B.  Surface Ballast: 
 
1.  Pavers:  For all areas, precast concrete pavers weighing not less than 10 psf nor 
more than 15 psf, manufacturer's standard size (maximum 24" x 24") with 
drainage channel backs and interlocking edges.  Fabricate from air-entrained, 
reinforced, normal weight concrete with a minimum 28-day compressive

bearing RIC/TIMA label on packaging. 
 
C.  Tapered System:

indicated as sloped or 
tapered to form crickets or 
provide slope for drainage, 
provide full thickness 
polyisocyanurate tapered 
units, used in combination 
with other specified non-
tapered boards to form re-
quired levels. 
 
D.  Insulation Thickness:  As required to achieve an average R=30 thermal resistance for 
total roof system. 
 
PART 3 - EXECUTION 
 
3.1  INSTALLATION: 
 
A.  Mechanically fasten the first course of insulation.  Do not use fasteners which will 
damage the vapor retarder, if any. 
 
B.  Vapor Retarder:  Loose lay vapor retarder in between insulation layers, below the dew point. 
PROVIDE THERMAL BARRIER ONLY 
WHERE REQUIRED. 
SLOPE STRUCTURE TO ACHIEVE DR-
AINAGE ON NEW CONSTRUCTION AND 
USE TAPERED INSULATION FOR CRICK-
ETS ONLY.  ON EXISTING "FLAT" 
ROOFS, USE TAPERED INSULATION AS 
REQUIRED TO ACHIEVE ADEQUATE DR-
AINAGE  
AUGUST 2010  UCB STANDARDS  07530 - 5 
 Lap, tape, seal, and flash vapor retarder to maintain integrity of the system. 
C.  Curb height from finished roof shall be 12” from roof to top of curb. 
D.  On Jobs the use glue, make sure lids are on cans around any air intakes to make sure fumes 
do not go inside to the air handling systems.  
 
E.  PVC roofs are acceptable. When job is completed, check all seams to ensure there are no 
cold welds. Use weldable metal for all scuppers and overflows and edge metal. Protect 
roofing membrane from damage if other trades are working on finished product. Small 
amount of material be given to roofing shop for any repairs necessary after warranty expires. 
On all pipes, use boots over pipe where possible. Do not wrap pipes unless absolutely 
necessary.
