re: Architectural Shingle Roof Replacement Questions (Hailstorm Aftermath)

A few things, in the valleys they should put ice and water shields, you can Google this.
A quick check on the lifespan of shingles:

The different asphalt shingle roof types and their expected lifespans are:

*3-tab shingles: The cheapest asphalt shingle type lasting between 15-30 years.

*Architectural shingles: Also called dimensional shingles, these asphalt shingles are mid-range priced and last between 20-30 years.

*Premium shingles: The highest price tag when it comes to asphalt shingle materials, these last between 25-40 years.

Hail damage, make sure they do a good check of all metal vents, metal stacks on the roof area.

As for location, I have family in Woodstock, Ga. A great area to visit.
