A. Starting at the eave, one layer of Underlayment should be applied to the deck, perpendicular to the slope. All felt sheets should be lapped a minimum of 2 inches over the preceding felt sheet. End laps should be a minimum of 4 inches. The felts should be nailed under the lap only as necessary to hold the felts in place until the shingles are applied.

B. Self-adhering modified bitumen underlayment. In locations where the January mean temperature is 30° F or less, an adhered bitumen membrane should be substituted for the felt underlayment starting from the eaves to a point 24 inches inside the inside wall line of the building to serve as an ice shield.

C. Drip Edge. Drip edges of minimum, 24 ga. metal should be provided directly beneath the shingles along eaves and rakes and applied directly to the edges of the deck. The underlayment should be positioned between the metal edge and the roof deck along the rake and over the metal edge along the eave.

3.04 TOISITE SHINGLE APPLICATION

A. General. Application shall be in accordance with the approved shingle manufacturer's latest printed specification and installation guides.

B. Starter Course. Before applying the first course of shingles, a row of shingles with the tabs removed should be applied along the eaves as the starter strip. Align starter course with the outer edge of the building, gutters or eaves as necessary.

C. Apply the first course of shingles flush with the starter course (end of tab) but without open tab joints overlapping starter joints. (stagger) Nail shingles with four nails per shingle. Be sure it is laid perfectly straight, checking it regularly during application against a horizontal chalk line.

D. The second course should be started with a shingle from which half of the first tab has been removed. The shingles shall be overlapped so that there is a 5.0" exposure or 6” and shall remain constant throughout the entire application.

E. The third course should be started like the first course, then the fourth like the second and so on throughout the entire application. This pattern allows the cutouts to be centered on the tabs of the shingles in the course following.

F. All shingles are to be nailed in place with nails - no stapling is permitted.

3.05 HIP AND RIDGE

Individual shingle tabs the entire width (11.8") of the shingle should be cut, trimmed to a taper and bent lengthwise across their centers for use as a hip and ridge covering. Application of the Toisite hip and ridge covers should begin at the lower end of a hip or at either end of a ridge. The hip and ridge covers should leave a 5.0" or 6” exposure and be applied in shingle fashion.

# NOTE As an alternative to the shingles, metal can be used as a hip and ridge cover.
