Motorized roll up screens adds value to any home. Homes that are built in areas where windows and doors remain open for large parts of the year need screens. Typical screens are considered part of the main structure of a home. Motorized roll up screens works in the same way as typical screens in that they screen out bugs, insects, dirt, and debris. Without screens covering doors and windows, insects, flies and other pests have free access to enter the home. Mosquitoes and flies breed quickly and are a nuisance. Keeping out flies and mosquitos was the first reason screens were added to the doors and windows of homes.
