What All Is Involved In The Installation Of DaVinci?

DaVinci Shingles with Ice and Water Shield UnderlaymentSpeaking in general terms there are certain items that are required for the installation of DaVinci roofing materials, of course, there are exceptions as well as substitutions according to where you live in the country, but for the most part, here are the requirements:
  • Decking
  • Drip Edge
  • Ice and Water Shield
  • Underlayment
  • Starter Course
  • DaVinci Shingles
DaVinci shingles must be installed on a smooth, flat surface.  If not, imperfections in the decking may transmit through to the finished roof.  All previous roofing materials from prior roofing jobs must be removed before installing DaVinci shingles.  Additionally, at minimum, it must be installed on 15/32"APA approved plywood or 7/16" approved OSB.
DaVinci Slate Drip EdgeDrip edge is a metal flashing that is required on gable ends and eaves.  An overhanging drip edge such as a "D" style version or a "F" style version is recommended on the gable ends to help mask the rib-structure on the underside of DaVinci shingles. 

Ice and water shield is a necessary component to a roof installation if the average daily temperature in January is 25 degrees Fahrenheit or lower where ice buildup is possible.  We require ice and water shield to be installed from the bottom edge to two feet above the exterior wall line on all eaves, in all valleys, on all gable ends, and all around all roof projections.

DaVinci Shingles being laid over underlaymentThe underlayment for DaVinci shingles varies depending on whether you are installing DaVinci Shake or DaVinci Slate. 
  • For Slate - for a Class A installation, one layer of 30# ASTM D 226 underlayment must be installed over the entire roof in addition to the ice and water shield.
  • For Shake - please refer to page 2 of the Shake installation guide for the 4 different methods the underlayment can be installed with our synthetic cedar shake.
Lastly, before you get to put on those beautiful imitation slate tiles or those fake cedar roof shingles you purchased from us, your roofer will lay down a starter course.  There are specialty tiles that we make for the starter course and each of those tiles should be installed extending past the drip edge by approximately 1".

If you are a roofer, please refer to our slate installation guide or our shake installation guide and don't hesitate to get in touch with our technical service department with any questions you may have.
