ImpactRidge™ Hip & Ridge Shingles Application Instructions | Owens Corning Roofing
Skip to main content

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 and 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 and ridge shingles to obtain a level application. Each shingle is perforated for separation into three 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: • 6 inches minimum roof deck boards • Minimum 3/8 inch plywood • Minimum 7/16 inch OSB

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: Check 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. Protect shingles from weather when stored at the job site. 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 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 recommends the use of nails as the preferred method of attaching shingles to wood decking or other nailable surface.

Hip & Ridge Application

  1. Separate each piece of ImpactRidge™ hip & ridge shingles into three individual shingles at the perforations.
  2. Create a starter shingle by removing the 6 inch exposure portion of the shingle.
  3. Beginning at the bottom of each hip or the end of the ridge opposite the prevailing wind direction, install the starter shingle using 1 fastener on each side, 1 inch from the side edge and 1 ¼ inch from the cut end.
  4. Continue installing shingles up the hip or ridge by fastening each shingle with 1 fastener on each side, 1 inch from the side edge and 7 ¼ inches from the exposed end. See Figs. 1 & 2.
  5. Apply remaining hip and ridge shingles in the same manner with a 6 inch exposure.
  6. When finishing the ridge, leave no headlap portion of the last hip and ridge shingle exposed. One option is to use the 6 inch exposed portion of a hip and 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 two nails, each 1 inch in from the 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.

Alternative Fastening Patterns

These products may also be fastened with 2 fasteners on each side, 1 and 2 inches from the side edge and 6 ¼ inches from the exposed end (See Fig. 3) OR with 2 fasteners on each side, 1 and 2 inches from the side edge and 7 ¼ inches from the exposed end (See Fig. 4).

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 two 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.
