How do roof costs compare by type of roofing?
Short answer. From least to most expensive, the common residential choices run roughly: 3-tab shingles, architectural shingles, designer and Class 4 shingles, exposed fastener metal, standing seam metal and synthetic slate, then tile and natural slate. Architectural shingles are the Georgia standard, with most full replacements in North Georgia around $8,000 to $16,000.
The main types, in cost order
- 3-tab asphalt: the budget option, flat look, lower wind ratings. Fewer are made each year. Often 15 to 20 years in Georgia.
- Architectural asphalt: the baseline for most homes. Commonly 20 to 25 years here with good ventilation.
- Designer asphalt: heavier, slate or shake look, higher price.
- Class 4 impact resistant asphalt: a premium over architectural, possible insurance credit.
- Exposed fastener metal: above shingles, needs fastener upkeep.
- Standing seam metal: often double or more a shingle roof, very long life when installed well.
- Synthetic slate or shake: premium priced, lighter than the real thing.
- Concrete or clay tile: heavy, needs a structure that can carry it, rare in North Georgia.
- Natural slate: the most expensive and longest lived, needs specialized installers.
Low slope sections are their own category
Porches, carports, and additions under about 2/12 cannot take shingles. They need a membrane or metal system, which is priced separately on the same job.
Choosing by Georgia conditions
Heat and humidity favor good ventilation and algae resistant granules. Hail favors Class 4 or metal, but read your policy for cosmetic damage exclusions on metal. Shade and pine needles favor a material that sheds debris and a plan for gutters.
