Almost all of the buildings these days use wood, vinyl and hardie siding. These all materials have their unique advantages and drawbacks. You probably would like to take into consideration the actual ease of cleaning. Hardie siding is usually wiped clean with force washing with moderate detergents, vinyl board can be even wiped down using a moist rag. Cedar siding is going to take a lot more maintenance – wooden slats must be stained and painted to keep their strength.
