Eaves, Hip, & Rake Installation Details for Tile Roofs

Broken ridge tile (C) D Friedman

This article series discusses best practices in the selection and installation of residential roofing. Also see our home page for clay tile roofing, starting at CLAY TILE ROOFING. Adapted/paraphrased with permission from Best Practices Guide to Residential Construction, chapter on BEST ROOFING PRACTICES:

A number of specialized flashings, tiles, and fittings simplify modern roofing tile installations.

At left our photo shows special ridge tiles on a home in New York state, including one broken tile that needs replacement. In this location leakage was minimal.

Key details for interlocking flat and profile roofing tiles are shown in Figure 2-26 and Figure 2-27 just below, illustrating both curved (below left) and flat (below right) clay (or concrete) roof tile installation fittings that help seal against the weather.

Eaves Closure Requirements on Tile Roofs

Figure 2-28: Eaves closure methods for clay tile roofs (C) J Wiley, S Bliss

Both profile and flat clay roof tiles need special treatment at the eaves to raise the bottom edge of the first tile to the correct height and to close off any openings to birds and insects.

For profile tiles, many tile roofing contractors use a metal birdstop, a preformed L-shaped strip with the vertical leg cut to match the underside of the first tile and fit snugly between the weather checks (see Figure 2-28 at left).

Figure 2-26: Eaves closure methods for clay tile roofs (C) J Wiley, S Bliss

With some high-profile clay or concrete roofing tiles, a special eaves-closure tile achieves the same effect as shown in Figure 2-26 above. [Click any of our images or tables to see an enlarged view.]

Figure 2-27: Special starter tile for clay tile roofs (C) J Wiley, S Bliss

With flat clay roofing tiles, the first course may be raised with a special starter tile, as shown at left in Figure 2-27, or by a metal eaves closure, raised fascia, or wood cant strip.

With a cant strip or raised fascia, a beveled wood or foam antiponding strip is required to prevent ponding of water along the eaves (Figure 2-29 below).

Ridge and Hip Requirements on Tile Roofs

Figure 2-30: Ridge and hip details for clay tile roofs (C) J Wiley, S Bliss

Unless hip and ridge tiles on a clay tile roof are going to be set into a continuous bed of mortar, special nailers are required to install them.

The hip and ridge boards are typically 2x3s to 2x6s set on edge to hold the trim tiles in an even plane.

They are toenailed in place and individually wrapped with felt (Figure 2-30 shown at left).

Hip and ridge tiles are later nailed on with a 2-inch head-lap, and the lower ends are sealed at the overlap with roofing cement or an approved tile adhesive.

Finally, mortar, special trim tiles, or other weatherblocking is applied to fill in gaps between the ridge and hip tiles and the field tile.

Rake Requirements on Tile Roofs

Figure 3-31: Rake details for clay tile roofs (C) J Wiley, S Bliss

 

Rakes on clay tile roofs may be finished with detached gable-rake tiles (as shown in Figures 2-26

and Figure 2-27 shown just above, or with highprofile tiles, trimmed simply with half-round trim tiles

as shown in Figure 2-31 shown at left.
