Across the western and southern United States, the most prominent and enduring architectural styles draw on Spanish and Mediterranean influences. The roofing material of choice for these styles is tile. Sometimes the use of tile alone does not provide the home/building owner with quite enough Spanish or Mediterranean flare. There are specialty installation techniques to solve this problem. We, at Eagle, will be producing a series of technical bulletins focusing on these techniques.
The first of these specialty installations addresses the hips and ridges of the roof. There are several ways trim tile can be used on the hips and ridges that will instantly add old-world charm to the look of the roof. This bulletin will concentrate on stacked hip starters, multiple trim courses, and random trim stacking.
Stacked Hip Starters
Typical installations call for the installation of one piece of trim at the bottom of each hip. The end can be left open in some regions, or it can be finished with mortar or a pre-formed mortar hip starter. A stylish departure from the norm is to stack tiles at the ends, creating a dramatic design element. There are several ways to create these stacks. Trim tiles cut to a smaller width and length, Boosted Accessory pieces, or the Capistrano field tiles- trimmed to remove the pan all provide the ideal sized pieces to create the stack. Another option is to cut trim pieces incrementally smaller to create a gradual stack.
Stack the pieces from 3-7 high, depending on the height of the board or riser you are using for trim attachment, before installing the first full trim piece. The tile at the bottom of the stack should be attached to the roof and each tile after should be attached to the tile below. Add to the look by using mortar between courses. In high wind areas, be sure to provide the necessary weather blocking.
Multiple Trim Courses
Another way to add old-world detail is to install multiple courses of trim on hips and/or ridges. For this detail, you will install your first course normally. Then add each additional course using an accepted method of attachment. You can finish the look with mortar at the nose of each trim piece. It is important to consult local building codes when deciding to add courses of trim tile.
Random Trim Stacking
Similar to the previous detail, you will start by installing the first course of trim tile normally. This time, though, you will add trim tiles to the hips and/or ridges randomly-using an accepted method of attachment. You can even vary the number of tiles stacked at each location. Then finish the look with mortar. Again, it is important to consult local building codes when deciding to use this detail.
