Having new siding installed is the one chance any homeowner has to completely change the exterior appearance of their house. It's "Extreme Makeover: Your House Edition." The fun part comes in the design phase as colors, accents, styles, and profiles are examined.
However, before we dive into the fun stuff, what do we want this siding to be made of? The most popular options are vinyl, steel, and composite materials. Many salespeople that come to your house for a "free in-home estimate" (translation: high pressure sales pitch), will go on to tell you that their product is the best and show you "kill pages" on all the rest.

For example, someone trying to sell you vinyl might show you pictures of all the other types of siding failing miserably: paint peeling off composite material, steel siding rusting and dented, wood-pecker holes in wood siding. Those pitching against vinyl will show pictures of faded, warped, chalky, and cracked vinyl siding.
Every type of siding can be shown as awful by the competition. Now, before you give up and start getting quotes on brick like the third little pig, let's break this down a little further in the interest of keeping the price from going through the roof.
Vinyl
Not all vinyl is created equally. "Builder-grade" vinyl popped up in many of the neighborhoods being mass built during the building boom. It was lower thickness, faded horribly, cracked easily, and gave vinyl a bad name. Vinyl can still be a great option for a long-term siding solution as long as you go with a minimum .046 thickness. Those panels are considered premium, so not only are they stronger, but they also get treated with much more fade protection. I'm still leery of very dark colors on vinyl; those colors just absorb too much sunlight over time. Using dark colors as an accent in the peaks on the front of the house is OK, and very popular; even better if the front of the house faces north and gets no direct sunlight.
Foam-backed vinyl options are really catching on as they add strength to the panel (no cupping), and they add insulation value. Those panels can come in the popular 6" exposure that composite boards come in. Hollow-backed vinyl typically comes in the narrower 4" or 4.5" exposure. Form-fit foam can be added to those panels for an extra cost.
Vinyl is low maintenance and will never need to be painted. Stick with a premium thickness and you'll be happy with the results.
