The answer to 'drip edge vs' is that drip edge and no drip edge are two different roofing installation methods with their own advantages and disadvantages. Drip edge is a metal flashing installed along the edges of the roof to direct water runoff and prevent damage to the fascia and siding. No drip edge means the roofing material extends past the roof's edge without any additional flashing.
Drip edge provides better protection against water damage and is generally recommended by roofing experts. It helps prevent rot, mold, and staining on the fascia and siding. Drip edge is also required by most building codes. However, it does add some additional labor and material costs to the roofing installation. No drip edge is a simpler and less expensive option, but it leaves the roof edges more vulnerable to water damage over time.
