New siding can give your home an immediate makeover and help make it easier to sell later. But siding isn’t purely decorative—it’s also your home’s first defense against the elements. Loose or cracked panels or shingles can allow entry to moisture and insects, leading to expensive structural damage.
At Consumer Reports, our testing shows significant performance differences among siding types and brands. Some siding is far less resistant to cracking from impacts in warm and cold weather, and some is less likely to stay put in a windstorm, based on the simulated 150-mph winds in our testing. We also find that some siding made from vinyl, still the best-selling material, is more prone to color change under ultraviolet light, especially important in sunny climates and where trees don’t provide much shade.
