Install the first panel 4” from the eave edge and the second panel 4” above the first panel. Stair-step diagonally across the roof as you install the Viro thatch roof panels, maintaining an exposure of 8”. At the hips, cut one panel in half and bend it to conform to the hip while allowing two hip courses to one field course.  Fasten each panel with at least three 1 ¾” ring shank roofing nails along the raised angular tabs of the panel binder.

Please see our Viro Thatch Installation Guide for more information.

How do you install Viro thatch palm on the hips of a roof?

Insert a half to a third of a field panel in between the regular panels going up the hip. Bend the panels around the hip. This will add an extra layer under the existing hip layers to make them a little fuller. It also helps the thatch lay naturally.

How do I install Viro thatch on the ridge of my roof?

Take the last panel and install it at the top of the ridge. On the other side, do the same thing so that the two thatch spines are against each other. We recommend using a half-round piece of bamboo to cover the spines.
