Refer to roof load diagram on page 2.IDENTIFYING BORAL ENVIROPRO ROOFING COMPONENTTo help identify the Boral EnviroPro product, Boral hascreated a patent pending design for the underlap/waterchannel and added two fastener locations (total of four)for each profile.Low (Flat) Profile: The primary fastening locations are theinner holes on the low profile.Primary Fastening LocationsPrimary Fastening LocationsMedium Profile: The primaryfastening locations are indicatedon the medium profile.Primary Fastening LocationsHigh Profile: The primaryfastening locations are the outerholes on the high profile.NOTE: Depending upon the profile selected for theproject, the Boral EnviroPro product may be installedin a “Straight bond” or a “Half (Broken) bond” pattern.“Straight bond” is illustrated in the Sidewall and TilePan details, while the “Half bond” or “Broken bond” isillustrated in the Skylight, Rake and Vent Pipe details.ROOFING LAYOUT PER PROFILEProfileLayout (Install) PatternStraight BondLow (Flat)MediumHigh Half (Broken) Bond 1

Boral EnviroPro Installation GuidelinesROOF LOADING BORAL ENVIROPRO COMPONENTThe loading shown below represents a method of placement of Boral EnviroPro product in relation to standardconcrete field tiles. It is not intended to suggest that this is the only method that will work. Each applicator will havepersonal preferences for the stack location and spacing. An important aspect of loading Boral EnviroPro productis to provide enough material at the location to have the correct amount of product for the detail being performed.NOTE: Green numbered blocks indicate suggestedlocations for the loading of the Boral EnviroPro product. Grey blocks indicate standard concrete fieldtile stacks.1. Course lines should be measured and chalkedaccording to the roof layout recommendation above,before loading the roof.2. Determine the approximate number of BoralEnviroPro product that is needed for each sectionof the roof.3. The spacing and location of the Boral EnviroPro product is determined by the number needed percourse.4. Starting on the third course from the eave, andcontinuing with every other course, distribute BoralEnviroPro product evenly over the roof. If cuts arerequired at gables, load one (1) Boral EnviroPro product per course of needed cuts.5. Load two (2) of the Boral EnviroPro product percourse at the hips and valleys.6. If more than one color of Boral EnviroPro productshas been selected to be installed, care should betaken upon roof loading to mix them throughout thecut detail locations.2
