Flared Wall Installation

To install Ecoshel on flared wall sections, all of the shingles in the Shingle-strip must be bowed at the same time.

 

For moderate flare, pre-drill the nail holes in the shingles, and drive the nails just enough to slightly bow the shingles. Then tap in all of the nails together, each nail a little at a time.

 

For more extreme flare, use narrow screws with fender washers in the keyway spaces between the shingles. Tighten the screws together, each screw a little at a time. You could also use wood pieces or a metal strip in place of the fender washers.

 

Fasten with nails placed in the normal position and remove the screws. Plug the nail holes with caulk.

Fasteners

Always use stainless steel fasteners. Other fasteners will result in black streaks, and won't last as long as the shingles.

Use only 2 fasteners per shingle. Position the fasteners about 1" above the butt line of the next course, and about 3/4" in from each edge.

For both roofing and siding applications, we recommend 1-1/2" stainless steel, ring shank, coil siding nails. You can also use stainless steel, medium crown staples.

If you are installing rigid insulation between the shingles and the sheathing, increase the nail length by the thickness of the insulation.

Hip & Ridge Units

Hip & Ridge units are built at custom angles that match the pitch of your roof. They can be installed over ridge vents, or over flashing. The inside dimension is 6" per side.

Copper flashing that extends about 1.5" past the H&R shingles will preserve the shingles below for a distance of about 15'. Copper strips are very effective at preventing the growth of moss and fungi that cause decay. Zinc is also effective in preventing decay, but steel core galvanized sheet may cause black streaks.

Installed Shingle Depth

These installed shingle profiles show the total depth of the installation at different exposures. Installations look better when corner board trim, and  the trim around windows and doors, extends further out than the shingles. Trim with an actual thickness of 1-1/4" works well.

 

Standard 2 x ___ lumber can be planed to provide 1-1/4" trim stock with crisp corners. Another option is to install strips of  7/16" plywood behind standard 3/4" trim.
