If you've received a sample of our DaVinci Shake roofing materials from one of our DaVinci Representatives, a roofing contractor or a distributor in your area, no doubt you have checked out the back of the shingle and wondered why it is "hollow".
It's "hollow" on purpose, actually. Each and every shingle has this unique engineered ribbing structure on the back of the shingle. Why? By having a ribbing structure in place, we are confident that the shingles will resist bending, warping or curling when installed correctly.
Also, you'll notice that our shingles have color all the way through the shingle. We do this so that if the shingles need to be cut for valleys or other areas of your roof that there isn't another color showing.
So now you may be wondering what happens with the ribbing structure when the shingles are cut? They are exposed, of course, but don't have to be when they are on your roof. The exposed edge can line up with the shingle next to it, and therefore you will not notice the cut. However, if this still concerns you, we also sell a solid accessory piece that can be purchased. Most of the time, though, your contractor will not need to cut our shingles (except in valleys and other places if your roof is more angled) because our DaVinci Shake comes in multi-widths, so your contractor can select the DaVinci synthetic cedar shake shingle width that he needs in that area.
If you contractor needs help in not exposing the ribbing structure, they can consult our installation guide or get in touch with the DaVinci Rep in your area or touch base with our technical department.
