One Way To Install Slate Hips and Ridges

Slate Hip and Ridge Joint | Ventilated Slate Ridges

HIPS

Slate Roof Central - Installing slate hips

Slate Roof Central - Installing a slate hip

Install furring strips along hip before slating roof. Follow chalk lines. These are 3/4" furring strips being used for standard thickness (3/16" to 1/4") slates. Furring strips were nailed to roof with 2.5" hot dipped galvanized common nails. The wood strips should be approximately 3X the thickness of the slates.

Install first piece of copper flashing over bottom of furring strips. This is 20 ounce copper. Flashing is nailed in place with 1.5" copper roofing nail.

Fold bottom of flashing to hide furring strips.

Install slates over flashing - nail into furring strips. Nails can be 1.5" copper roofing nails, although 2.5" copper roofing nails will need to be used in places.

Install next piece of step flashing over hip slates. A single nail is sufficient.

 

Slate Roof Central - Installing a slate hip

Install next pair of hip slates over step flashing. At least two nails per slate is required. Three is better. If you're going to nail through the lower slate, drill first with a 3/16" masonry bit and use a 2.5" copper roofing nail.

This flashing is 10" long x 8" wide on 8"x16" hip slates.

The flashing is folded lengthwise in half (4" each side). The 16" long hip slates are overlapped 8" (halfway) by both the overlying slates and the flashings. The 10" step flashings then overlap each other by 2".

Continue up the hip in this manner, flashing over the top of each pair of hip slates. Install the slates in pairs, not one side at a time. The hip slates do not need to be tapered - most can be installed without cutting. You can cut the exposed corner for a decorative effect, however.

The finished hip is leakproof and permanent.

HIP AND RIDGE JOINT

 

Slate Roof Central - Installing a ridge and hip juncture.

A ridge is coming to a hip. Install copper at joint over valley.

 

Installing a ridge/hip juncture.

Install another pair of ridge slates cut to fit over the valley center. Install next step flashing over these slates. Install loose (not nailed) strap hanger over this copper step flashing.

Lay pair of short ridge slates over strap hanger on bed of adhesive. In this case, GE Silicon II, clear lifetime caulk. Bottom edge of strap folds up to hold pair of slates in place while adhesive sets up.

 

Slate Roof Central - Installing a ridge/hip juncture.

Proceed up hip with first pair of hip slates cut at an angle to fit against ridge slates. Install step flashing under each pair of hip and ridge slates. All ridge slates should be caulked at joint. Hip slates do not need caulked at joint.


VENTILATED SLATE RIDGES

Again, install furring strips on both sides of ridge opening before slating roof.

 

Slate Roof Central - Installing a ventilated slate ridge

Roll a low-profile plastic ridge vent material (Owens Corning VentSure shown above) over the furring strips.

 

Slate Roof Central - Installing a ventilated slate ridge.

Nail the vent material to the furring strips. Install ridge slates and flashings in the same manner as installing slate hips, except ridge joints should be caulked. You will need longer nails when installing ridge slates over vent material. In this case, 2.5" copper nails were used.
