Drip 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.
The 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.
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.
