Deciding how much waste should be figured for the different DaVinci roofing products requires the contractor to answer a few questions.
- Can the installers be counted on to be careful and save material where they can?
- If they cut a tile for a valley will they use the remnant on the corresponding hip?
- On Multi-width installation will they measure for the correct tile on the gable end or will they cut the tile and throw away the rest as waste?
- On Single-Width will they use the cutoff portion from the right side of a gable and use it on the left?
If the answer to all of these questions is yes then DaVinci Multi-Width Slate and Shake can be installed with < 1% waste; unless there are valleys in the roof which don’t have corresponding hips. In that case there is 1 square of waste for every 100 linear feet of valley (that counts both sides of the valley). Single-Width Slate and Shake can be installed with < 2% waste with the same stipulation as above.
Bellaforté Slate and Shake will have more waste than our other products because often times the remnant of a cut cannot be reused. A good rule of thumb for the Bellaforté products is 4% waste with a conservative installer but that can go up to 8% if the installers are not conscientious about saving material.
