Applying Ice and Water Shield
For regions susceptible to ice dams or heavy snowmelt runoff, adding an ice and water shield at eaves and valleys starter strip shingles is vital.
How Does It Work?
This membrane adheres directly to the roof deck, preventing moisture buildup that could lead to leaks over time.
Installing Drip Edge
A drip edge helps direct water away from the fascia board—essentially protecting it from rot over time while enhancing aesthetics.
Where Is Drip Edge Installed?
Drip edges are typically applied along eaves before laying down shingles but after installing underlayment for maximum effectiveness.
