The answer to 'drip edge vs' is that drip edge and no drip edge are two different roofing techniques with their own advantages and disadvantages. Drip edge is a metal flashing installed along the eaves and rakes of a roof to direct water away from the fascia and prevent rot and damage. No drip edge means the roofing material extends past the edge of the roof without any metal flashing. Drip edge provides better water protection but costs more to install, while no drip edge is a simpler and more affordable option.
Drip edge is generally recommended for most roofs as it helps extend the life of the roof and prevents water damage. However, no drip edge may be suitable for some types of roofing like metal or synthetic slate where the material can overhang the edge without issue. Ultimately, the best choice depends on the specific roof, climate, and budget of the homeowner.
