::What Should I Know When Buying Vinyl Siding?

• Generally, thicker is better. The thinner the siding, the more it could sag over time. The thicker the siding, the stiffer and more durable it will tend to be. The best vinyl siding is thick and stiff.
• Wind resistance. You want siding that will stay on the house in a storm. Some manufacturers actually warranty their siding in winds up to 130 mph. Ask about wind resistance and the warranty.
• Getting attached to siding. Unlike wood, vinyl siding is not attached tightly to the house. It more or less hangs on the side of the house, because it contracts and expands with heat and cold. A double hem mounting area usually provides better attachment than a single hem. If the siding is too tight, there's poor ventilation. If it's too loose, it can be noisy. Net 'n net, it needs to be installed properly.
• Rain resistance. Because it hangs loosely, vinyl siding is less likely to trap moisture. However, there are also areas where water can leak inside, so proper flashings should be installed, as well as house felt or builder's wrap.
• Fading factor. The best vinyl siding, which is more expensive, tends to fade less than cheaper siding. Look for UV protection in the description, and ask about how it will stand up to sunlight. Also, if you live in a sunny climate, ask about whether a light color would fade less than a dark color.
• Pick you profile. Some vinyl siding is designed with a deeper profile, or a more pronounced bend in the design of the siding. This generally looks more like wood. So consider the overall look of the siding, to be sure you get what you want.
