A big code change for Georgia roofers happened recently. Drip Edge, the slim flashing around the outer edge of a house, is now required for all roofing contractors.
Drip Edge (definition from Wiktionary):
What does this mean for homeowners?
If you're a homeowner and in the market for a new roof, make sure the contractor you hire has "drip edge" included in your estimate. If not, you should look elsewhere.
If you're looking to purchase a new home, anything built within the last two years should have drip edge installed. If you can't tell by looking at it where it's there or not, have an inspector make sure it's there before you make your purchase. If it's not there you may want to use this in your negotiations for getting the house.
