Whether it's your first time or your tenth time installing DaVinci synthetic lightweight tiles it's always a good thing to pick up a few tricks of the trade.
Although, for example, our DaVinci Shake sports a 5/8" thick butt end, it remains lightweight due to the engineered ribbing structure on the back of the shingle. This is also true of our slate. Because of this ribbing structure, care needs to be taken when cutting slates or shakes for the valleys or at a gable end (don't worry about the overhang on an eave - we have solid starters).
In the valleys or on the gable end, the underside of the shingle needs to be hidden by standard metal flashings. This is especially important when considering which drip edge to use.
In the photograph in this post, you see DaVinci lightweight roofing tiles installed on a gable end over an overhanging drip edge metal flashing. This kind of drip edge, sometimes called style D or F, masks the ribbing structure on the underside of DaVinci.
If you have more specific questions about cutting DaVinci simulated shake roofing, be sure to reference our DaVinci Shake Installation Guide. If you have more questions or concerns from there, be sure to get in touch with a member of our customer service department who can help you further.
