Your roof should already have a ventilation system in placeIf it doesn't, I would get a contractor to check the condition of the Attic space to make sure none of the wood is rotted away Ventilation for the Attic space is essential in keeping the Attic space dry, and the vents are open year round They make a variety of material to vent the Attic withIf you live in an area of the country that isn't prone to hail, then plastics should be okIf you do get some violent weather, I would go with metal.
as quick and consise as possible most newer houses have one or a combination of soffet , ridge vent ,or some sort of attic fan or smaller roof vents 1 per ventilation is nessessary for many reasons most important , the warranty on your shingles or roofing material requires some sort of ventilation , also your ac bill in the summer will be cheaper 2yes a ridge vent or soffet would always remain open and an attic fan will kick on and off with a thermostat smaller roof vents would also always be open 3on the attic fan it comes with a dome or cover .usually aluminum or steelall others are simply one piece
1is it necessary.? The UBC require an attic to be vented at the rate of 1:300 (1sq.ftfor each 300sq.ftof attic area)Usually satisfied by screened vents at the rafter tails and gable ends2is the opening remain open all year around.? Since they are inactive (static), yes3what is the best material for the doom on the roof vent? Preformed galvmetal.
It uses a version three gearboxYou can put a higher power spring in it if you wantm120 should bring you right around 400M130 should get you into the lower 400s, up to 430.
