Impactridge® Hip & Ridge Shingles

CAUTION: DO NOT MIX MATERIAL BEARING DIFFERENT LOT NUMBERS, REFER TO THE LOT NUMBERS LOCATED ON THE SIDE OF THE BUNDLE.

Note: Off ridge vents should be used. Use of shingle-over ridge vent may affect the impact resistance classification.

Complete shingle application on roof deck before applying Hip & Ridge Shingles. Hip Shingles must be applied before Ridge Shingles. Note: If a new roof is being applied over an existing roof, remove the old Hip & Ridge Shingles to obtain a level application. Each shingle is perforated for separation into 3 Hip & Ridge Shingles.

Precautionary Note:

The manufacturer will not be responsible for problems resulting from any deviation from the recommended application instructions and the following precautions:

Roof Top Loading: Lay shingle bundles flat. Do not bend over the ridge.

Roof Deck: Minimum 6 inch roof deck boards, minimum 3/8 inch plywood, minimum 7/16 OSB, sheathing spaced minimum 1/8 inch and maximum 1/4 inch.

Regardless of deck type used, the roofing installer must:

1. Install the deck material in strict compliance with the deck manufacturer’s instructions.
2. Prevent the deck from getting wet before, during and after installation.

Ventilation: Must comply with local building codes.

Handling: Use extra care in handling shingles when the temperature is below 40°F.

Storage: Store in a covered ventilated area at a maximum temperature of 110°F. Bundles should be stacked flat. Do not store near steam pipes, radiators, etc.

Fastener Requirement: Use galvanized steel, stainless steel or aluminum nails minimum 12 gauge shank with 3/8 inch diameter head. Owens Corning Roofing recommends that fasteners comply with ASTM F1667. Must comply with local building codes.

All Fasteners must penetrate at least 3/4 inch into the wood deck or completely through sheathing.

Notice: Owens Corning Roofing requires the use of nails as the method of attaching shingles to wood decking.

Hip & Ridge Application

1. Apply Hip & Ridge Shingles as shown, bending them over the hip or ridge lengthwise.
2. Apply ridges after hips have been applied, beginning on end of ridge opposite prevailing wind direction. See Fig. 1.
3. Apply shingles with a 6 inch exposure.
4. Fasten each shingle with 2 fasteners on each side, 1 inch and 2 inches from the edge and 6 3/8 inch from the exposed end. See Fig. 2.
5. Apply remaining Hip & Ridge Shingles in the same manner with a 6 inch exposure.
6. When finishing the ridge, leave no headlap portion of the last Hip & Ridge Shingle exposed. Use the 6 inch exposed portion of a Hip & Ridge Shingle, cutting a piece the appropriate length to extend over the headlap portion of the shingle to the end of the ridge.
7. Fasten final piece with 4 nails, each 1 inch and 2 inches in from each side edge and 1 inch in from the end of the ridge. Cover exposed fasteners with asphalt roof cement. Asphalt Roof Cement must meet ASTM D4586 Type I or Type II (Asbestos Free).

Note: Please be aware that excessive amounts of asphalt roof cement could blister the shingle.

Installing Double Hip & Ridge

Applying a double layer of shingles to hips or ridges is easy to do and creates a more aesthetically pleasing appearance. Simply install the shingles using the method described above, but fasten 2 shingles simultaneously — one on top of the other. Make sure fasteners are long enough to penetrate through both layers of shingle and completely through the roof deck. See Fig. 3.
