PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	Verify surfaces are uniform free of ridges, warp or voids, smooth, clean and dry
C.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Removal of Existing Roofing:
1.	Remove all existing roofing down to the roof deck.
2.	Verify that deck is dry, sound, clean and smooth, free of depressions, waves and projections.
3.	Repair all holes over 1 inch (25 mm) diameter and all cracks over 1/2 inch (12 mm) in width.
4.	Replace rotted or otherwise damaged decking with new materials of equal thickness.
B.	Prepare roof deck using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions. Roof surface must be free of water, ice, and snow prior to and during roofing project. If preparation is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.
1.	Clean all work surfaces thoroughly prior to installation of underlayment.
2.	Install crickets on the upslope side of any chimney located on a roof steeper than 6:12, or wider than 24 inches (610 mm).
3.	Where practical, install all plumbing vents and other roof penetrations prior to installation of tiles.
C.	Do not proceed with installation until roof deck has been properly prepared and deviations from manufacturer's recommended tolerances are corrected. Commencement of installation constitutes acceptance of conditions.
3.3	UNDERLAYMENT INSTALLATION
A.	Install using methods recommended by manufacturer and requirements of local building code.
B.	Ice and Water Barrier: Install at the following locations in accordance with the manufacturer's recommendation.
1.	Eaves: On all roofs, install at least 24 inches (610 mm) beyond the interior face of the warm exterior wall.
2.	Valleys: Install a 36 inch (914 mm) wide barrier centered on valley.
3.	Vent Pipes: Extend at least 24 inches (610 mm) around all roof penetrations.
4.	Rake Edges: install along the entire length of all rake edges prior to the installation of metal drip edges.
5.	Hips and Ridges: Install along entire lengths. Cut slots where ridge vents are present to allow proper ventilation.
C.	Felt Underlayment:
1.	Install one layer of felt underlayment over all locations not covered with ice and water barrier. Run sheets horizontally and staple or nail in place.
2.	Where roof slope exceeds 4:12, horizontal laps shall be at least 3 inches (76 mm).
3.4	COMPOSITE SLATE INSTALLATION
A.	Install in accordance with manufacturer's instructions and requirements of local building code.
1.	3:12 - 4:12 slope: Install with 6-inch (152 mm) tile exposure for Classic Slate.

B.	Secure using two fasteners per tile. Where local building code requires additional fasteners, install such that they are at least 2 inches (52 mm) from all keyways, penetrations, flashings or other vertical seams. Fasteners must be long enough to penetrate at least 3/4 inch (19 mm) through plywood, into solid wood, or dimensional lumber.
C.	Install hip and ridge tiles over all hips, ridges or ridge vents. Preformed Ridge Tiles require 6-inch (152 mm) exposure for Classic Slate and 6-inch (152 mm) to 8-inch (203 mm) exposure for Aledora Slate. Hip and Ridge tiles may require longer length fasteners.
D.	At all valleys, install metal flashings in accordance with manufacturer's instructions.
E.	Embed step flashings with every course of slate at all sidewalls. "L" flashings are not recommended.

H.	Hand nail all Roof Tiles with ambient temperatures less than 45 degrees F (7.2 degrees C).
I.	Do not install Roof Tiles with ambient temperatures less than 32 degrees F (0 degrees C) for Classic Slate.
J.	Do not install Roof Tiles with ambient temperatures less than 20 degrees F (minus 6.7 degrees C) for Aledora Slate.
3.5	VENTILATION INSTALLATION
A.	Ridge Vent:
1.	Cut continuous vent slot through sheathing, stopping 6 inches (150 mm) from each end of ridge.
2.	Cut opening at ridge 1-1/2 (36 mm) to 2 inches (51 mm) wide, centered on ridge. Stop at least 6 inches (152 mm) from rakes or valleys.
