VINYL SIDING

Vinyl siding is a low-maintenance cladding. There won’t be a need to scrape and reapply paint or any need to caulk joints. All that is needed is a yearly wash with a hose and that should be the most maintenance you’ll probably ever encounter with vinyl.
It is a relatively durable product, especially if it has an insulation backing. The thicker the siding, the more durable it will be. Vinyl will never rot like wood and wood-based products can and it is non-porous so birds, insects or other pests will leave it be.
Choosing Vinyl can save you money, now, and in the long run over other options such as wood. Of course, the top of the line premium vinyl products will be more expensive than the entry level grade versions. 
With the advances of technology, finding the perfect color for your home should be no problem at all. You won’t have unlimited options but they far exceed what they did when vinyl siding was first introduced back the 1950’s and 60’s.
The flexibility of vinyl siding allow it to absorb impact better than more malleable materials, such as, metal which can dent if struck hard enough. Products with an insulated backing are more durable and provide an additional layer of strength.

Cement (Hardie) SIDING

Cement Siding or Hardie Siding Is more expensive than Vinyl but has a lot more benefits.

Water can damage your home like nothing else can. It may be gradual, but it is relentless, and can cause mold, swelling, cracking, and color separation. Cement siding is specifically engineered to withstand damage from moisture and rot, and will hold their own, come rain, sleet, or snow. Severe weather will test the strength of your home. Hurricanes, hail and blizzards hit hard and fast. Extreme droughts and relentless heat can go on and on. Your choice of siding, along with proper installation, can help your home stand up to these unpredictable elements. One thing’s for sure: As the years go on, we all show signs of aging. But since cement siding was created to stand up to the demands of your specific climate, they will look great for years, saving you time and money.

Mother Nature’s creatures can wreak havoc on some types of siding. Because it’s wood, OSB or wood-composite siding can be pecked by birds and devoured by insects. Not cement siding.
Then comes function. Vinyl melts easily in a fire (or even from the reflection of the sun off Low-E glass windows); Cement siding is noncombustible. Vinyl may crack and warp from the elements; Cement Siding resist warping, sagging and melting. Cement siding is not only less expensive than wood, it won’t be eaten by animals or insects. It also resists water absorption better than wood even where the manufacturer’s recommended protections are followed, helping protect against mold.
