NOTE **
NOTE ** This section is based on the CertainTeed Roofing Collection, the country’s most extensive line of fiber glass shingles.  CertainTeed pioneered the concept of multi-layered shingles, widely known today as “architectural” shingles, and has led the industry in color innovation with complex color blending technology and the introduction of bold designer shingle colors.

B.	Verify that roof penetrations and plumbing stacks are in place and flashed to deck surface.

C.	Verify roof openings are correctly framed prior to installing work of this section.

D.	Verify deck surfaces are dry and free of ridges, warps, or voids.

3.2	ROOF DECK PREPARATION

A.	Follow shingle manufacturer's recommendations for acceptable roof deck materials.

B.	Broom clean deck surfaces under eave protection and underlayment prior to their application.

3.3	INSTALLATION - EAVE ICE DAM PROTECTION

A.	Place eave edge and gable edge metal flashing tight with fascia boards.  Weather-lap joints 2 inches (50 mm).  Secure flange with nails spaced 8 inches (200 mm) on center.

B.	Apply CertainTeed "WinterGuard" Waterproofing Shingle Underlayment as eave protection in accordance with manufacturer's instructions.
NOTE ** Change dimension below to 48 inches (1,220 mm) or greater for low slope roofs or severe climatic conditions.
C.	Extend eave protection membrane minimum 24 inches (610 mm) up slope beyond interior face of exterior wall.

3.4	INSTALLATION - PROTECTIVE UNDERLAYMENT
NOTE ** Delete first two paragraphs below if all roof slopes are greater than 4:12.  Otherwise, select either complete WinterGuard underlayment or Roofers’ Select or D4869 underlayment in combination with eave ice dam protection.  WinterGuard is an improved version of standard underlayment, developed to resist standing water held on a sloped roof at eaves and valleys by ice dams and to resist wind-driven water.  WinterGuard can be used to cover the entire roof deck, rather than just eaves and valleys, when the slope is so low (2:12 to 4:12) as to permit wind to drive rain beneath the shingle.  Assure sufficient ventilation of space beneath the deck upon which WinterGuard is applied, as WinterGuard is a vapor barrier.
A.	Roof Slope Between 2:12 and 4:12: Apply one layer of "WinterGuard" over all areas not protected by WinterGuard at eaves, with ends and edges weather-lapped per application instructions.  Stagger end-laps each consecutive layer.  Nail in place.

B.	Roof Slope Between 2:12 and 4:12: Apply two layers of Roofers’ Select or D4869 underlayment over areas not protected by WinterGuard at eaves, with ends and edges weather-lapped minimum 19 inches (480 mm). Stagger end laps each consecutive layer.  Nail in place.

C.	Roof Slope 4:12 or Greater: Install one layer asphalt felt shingle underlayment perpendicular to slope of roof and lap minimum 4 inches (100 mm) over eave protection.

D.	Weather-lap and seal watertight with asphalt roofing cement items projecting through or mounted on roof.  Avoid contact of solvent-based cements with WinterGuard.

3.5	INSTALLATION - VALLEY PROTECTION

A.	For "closed-cut," "woven," and "open" valleys first place one ply of WinterGuard, minimum 36 inches (910 mm) wide, centered over valleys.  Lap joints minimum 6 inches (152 mm).  Follow instructions of shingle and waterproofing membrane manufacturer.

3.6	INSTALLATION - METAL FLASHING

A.	Weather-lap joints minimum 2 inches (50 mm).

B.	Seal work projecting through or mounted on roofing with asphalt roofing cement and make weather-tight.

3.7	INSTALLATION - ASPHALT SHINGLES

A.	Install shingles in accordance with manufacturer's instructions for product type and application specified.

3.8	FIELD QUALITY CONTROL

A.	Field inspection will be performed under provisions of Section 01400.

B.	Visual inspection of the Work will be provided by Owner. If conditions are unacceptable, Owner will notify the Architect.

3.9	PROTECTION OF FINISHED WORK
