Asphalt shingles are the most common roofing materials in America because they are
effective in all environmental conditions. Quality varies widely from 3-tab to trilaminate
dimensional. For the longest lasting asphalt type roofing make sure they pass the ASTM
D3161, Class F (110 mph) or ASTM D7158, Class H (150 mph) wind tests and the
AC438 durability test. Upfront costs are low, but you should expect to replace the
shingles after about 20 years. If you live in a hail prone area, consider impact resistant
shingles which have a UL 2218 Class 4 rating. Impact resistant shingles may qualify for
a discount on your homeowner’s premium or discount on your deductible.
Metal roofing comes in vertical panels or shingles resembling slate, tile, and shake –
and lasts about 60 years. Metal excels at sloughing off heavy snow and rain, will not
burn and resists high winds. It is lightweight and can be installed over existing roofs.
However, metal can be noisy during rainstorms, and may dent from hail. Average
costs range between $5 and $12 per square foot, depending on type and style of metal
– which is more than asphalt but less than concrete tiles. Corrosion also varies by
Stone Coated Steel
Interlocking panels mimic slate, clay or shingles and resist damage caused by heavy
rains (up to 8.8 inches per hour), winds of 120 miles per hour, uplifting, hail, and freeze-
thaw cycles. Consequently, they are an economical, effective choice for wet, windy
regions or areas prone to wildfires. Some stone-coated steel roofs are warranted for the
lifetime of the house.
Rubber Slate Roofing
Rubber slate looks natural and can be cut to fit intricate roofs like those found on
Victorian homes. Rubber slate roofs can last 100 years but can be damaged by satellite
dishes and walking – so may also be susceptible to damage by hail, like slate. Roofing
professionals that are trained to install rubber slate may be hard to find.
Clay & Concrete Tile Roofing
Clay and concrete roof tiles can withstand damage from tornadoes, hurricanes or winds
up to 125 miles per hour and even earthquakes, according to "A Summary of
Experimental Studies on Seismic Performance of Concrete and Clay Roofing Tiles" by
the University of Southern California for the Tile Roofing Institute. They are good in
warm, dry climates. They may require extra support to bear their weight, and they are
likely to break when walked on.
Solar Tile Roofing
Advanced solar collectors integrate seamlessly into existing shingles, generating up to 1
kilowatt of energy per 100 square feet. They are particularly good for sunny roofs in
homeowners’ associations that forbid typical solar panels. While they may help offset energy costs with solar power, they also cost more than traditional solar options.
