Screen rooms, as opposed to sunrooms, are just what the name implies- a room with walls that consist of screen. A screen room will allow you to enjoy the breeze and the outdoors with out the nuisance of mosquitoes and other bugs. The same roof styles available with sunrooms are also available with screen rooms, including the non-shingled studio roof as well as shingled shed and gable roofs.
As with sunrooms, an experienced design consultant will be able to look at your house and advise you as to which roof style best fits your personal situation. For some privacy and also for protection of lower screen material, a solid knee wall can be added with vinyl siding on the outside which ties the room in nicely with the existing house.
