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 inch furring strips being used for standard thickness (3/16 inchto 1/4 inch) slates. Furring strips were nailed to roof with 2.5 inch hot dipped galvanized common nails. The wood strips should be approximately 3 times 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 inch copper roofing nails.

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

 

Slate Roof Central - Installing a slate hip

Install the next piece of step flashing over the pair of hip slates. A single nail on either side is sufficient.

 

Slate Roof Central - Installing a slate hip

Install the 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 inch masonry bit and use a 2.5 inch copper roofing nail.

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

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

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 and most can be installed without cutting. You can cut the exposed corner for a decorative effect, however.

The finished hip is leakproof and permanent.

Lay pair of short ridge slates over strap hanger on bed of adhesive. In this case, "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 inch copper roofing nails were used.
