			1.	Form flashing lengths square, accurate to profile, in maximum possible lengths; form flashing lengths free from distortion or defects detrimental to appearance or performance.
			2.	Hem edges of flashings exposed to view a minimum 1/4 inch on underside.
	** NOTE TO SPECIFIER ** Metal flashing is required for all tile installations at eaves, valleys, wall intersections, and roof protrusions. The manufacturer's preferred material is 16 oz copper sheet. Other metal to match gutter material is also acceptable. Delete all but one of the following flashing material paragraphs.
		B.	Eave Flashings and Other Metal Flashings: Copper sheet, ASTM B 370, cold rolled, natural finish; 16 ounces per square foot minimum thickness.
		C.	Eave Flashings and Other Metal Flashings: Copper sheet, ASTM B 370, cold rolled, natural finish; 20 ounces per square foot minimum thickness.

	** NOTE TO SPECIFIER ** Delete aluminum flashing if not required. Aluminum flashing is desirable for eave flashing due to its compatibility with aluminum gutters, but should not be used for other flashing due to its limited life span when the painted surface is damaged. If either valleys or vertical intersections occur on this project, include one of the other metal flashing paragraphs above and change its heading to read "Metal Flashings Other than Eave Flashings."
		F.	Eave Flashings: Aluminum sheet, ASTM B 209; 0.019 inch minimum thickness.

Concealed sealants along gable rakes, ridge/hip trim and flashings with asphalt saturated felt underlayment shall be non-running, heavy body Plastic Roof Cement that meets or exceeds the requirements of ASTM D-2822-75 and Federal Specifications SS-S-153C (Type 1) or equal. Sealants used with EPDM or Synthetic Underlayments shall be per manufacturer's recommendation.
		H.	Exposed sealants, such as those used on counter flashings or non-soldered joints, should be high quality sealants to meet or exceed requirements of U.S. TT-S-00230C, U.S. Fed Cat. No 8030-965-2397, Canadian 19-GP-5M, ASTM C 290-79 or equal.

			2.	Verify roof openings are correctly framed prior to installing Work of this section.
			3.	Verify deck is of sufficient thickness to accept fasteners.
			4.	Verify deck surfaces are dry, unfrozen, and free of ridges, warps, and voids
		B.	Installer's Examination: Examine condition of deck prior to installation. Notify Architect if conditions are unacceptable. Beginning construction activities of this section indicates installer's acceptance of conditions.
	3.2	PREPARATION
		A.	Broom clean deck surfaces prior to installation of underlayment.
		B.	Coordinate with installation of flashing, gutters, vents, skylights and other adjoining work to ensure proper sequencing. Do not install roofing materials until all vent stacks and other penetrations through roof sheathing have been installed and securely fastened.
		C.	Arrange three or more stacks of roof tile at installation area; mix tile from stacks as installation progresses for consistent color blend. Do not overload roof surface with staged materials.
	3.3	INSTALLATION

	** NOTE TO SPECIFIER ** Coordinate Drawing details with the roof tile manufacturers instructions and recommended details for the roof tile specified. Extend eave fascia and plywood eave blocking above roof deck 1-7/8 inches to ensure proper cant for bottom row of tile. For slopes below 3:12 in the sun belt or 4:12 in severe weather areas, use two piece eave metal and cant strips instead of blocking over the fascia. For Spanish tile, the eave fascia is level with the roof deck. When vertical battens are installed for Flat, Riviera and Spanish tile, raise eave fascia to compensate for the thickness of the vertical batten. For English and Turret shingles eave fascia and plywood eave blocking shall extend above roof deck 7/8 inch to ensure proper cant for bottom row of shingles with a minimum slope of 4:12 in the sun belt and 6:12 in severe weather areas. For Spanish Pans and Covers eave fascia shall extend above roof deck 7/8 inch to ensure proper cant for bottom row of pans and covers with a minimum slope of 5:12
		B.	Verify that the eave fascia is installed as required for the specified roof tile.

			2.	Extend self seal membrane up roof slope minimum 2 feet beyond interior face of exterior wall or as required by code, whichever is greater.
			3.	Place each successive ply overlapping top edge of previous ply 3 inches.
		D.	Valley Flashings: Install 24 inch to 28 inch standing seam, double rib (for closed valleys) or 24 inch double rib valley flashing (for open grouted valleys).
			1.	Form flashings in accordance with manufacturer's instructions for valley type indicated.
			2.	Apply flashing over 36 inch full width vertical underlayment centered in all valley areas.

	** NOTE TO SPECIFIER ** The underlayment and flashings provide the primary weather proofing for the tile roof system. The building should be water tight before roof tile is installed. Select one of the following three systems specified in the following paragraphs and delete the systems not required. Two layers No.30 roofing felt (sometimes referred to as 30 LB felt) is the minimum underlayment recommended for severe weather areas, but is not acceptable for very low slope roofs. For slopes below 3:12 in the sun belt and 4:12 in severe weather areas, single ply roofing such as EPDM over vertical battens should be used as underlayment. Roof deck must be clean, smooth and dry when underlayment is applied. Do not use a slap stapler to install underlayment or button/cap nails with the battens. Note that rubberized underlayments will stretch in the hot sun and must be rolled out and loose laid without stretching when nailing.
		E.	No.30 Underlayment: Install 2 plies underlayment over entire roof area, parallel to eaves.
			1.	Place first ply 18 inches wide at eave edge, with bottom edge extending 1/4 inch over lower edge of eave flashing; seal to eave flashing.

			5.	Nail horizontal seams 1 inch from exposed edge of felt; space nails in accordance with manufacturer's printed instructions for roof slope.
			6.	Overlap vertical seams minimum 6 inches, seal lap with plastic cement, then nail at 3 inches on center; stagger vertical laps of each successive layer so that vertical joints do not align in any two adjacent plies.
			7.	Ridges, Except at Ridge Vents: Extend underlayment over ridges 6 inches on each side making a double layer.
			8.	Hips: Extend underlayment over hips 6 inches on each side making a double layer.
			9.	Valleys: Overlap metal valley flashing 3 inches and seal to metal.
		F.	Rubberized Underlayment and Synthetic Underlayment: Install underlayment over entire roof area, parallel to eaves.
			1.	Install in accordance with manufacturer's printed instructions.
			2.	Place first ply at eave edge, with bottom edge extending 1/4 inch over lower edge of eave flashing; seal to eave flashing.
			3.	Place each successive ply overlapping top edge of previous ply 3 inches.
			4.	Ridges, Except at Ridge Vents: Extend underlayment over ridges 6 inches on each side making a double layer.
			5.	Hips: Extend underlayment over hips 6 inches on each side making a double layer.
			6.	Valleys: Overlap metal valley flashing 3 inches and seal to metal.
