I am debating on replacing my current roof with either shingles or metal. I am wondering what would be the best option in terms of resale value and durability. What are your opinions on each? Also, and some what more importantly, is a ridge vent necessary with a metal roof as it is with a shingled roof. My house was built in 1993 and it wasn’t common to install ridge vents during that period. My metal roofing contractor has told me that they don’t typically install them if they are not there already because the metal reflects heat rather than absorb it like shingles. The house has gable vents on each side. Is it a big deal and should it be done? Our electricity bill is very reasonable and I don’t want to do anything to make it worse while trying to make it better. I am afraid that I may have to much heat lost during the winter. Any thoughts? Thanks. And so today I found out that… Good attic ventilation is important regardless of roof type. Ventilation helps keep the home cooler in summer. It helps avoid dangerous accumulation of moisture and it helps avoid winter ice dams. Good ventilation requires intake at the eaves mostly and exhaust. A ridge vent encourages the best distribution of fresh air throughout the attic and is very effective. Today’s metal roofs come in a wide variety of styles. Some of the lower end ones have exposed Fasteners which can require maintenance eventually. BUt the better metal roofs have concealed Fasteners as well as allowance for the metal’s thermal movement. They make incredibly lasting roof choices. I have had metal on all three of my homes and loved them all. Also as far as winter heat loss. . You need to avoid that with insulation on the floor of your attic. The roof actually has nothing to do with it and again to avoid winter ice dams you want your attic to be as cold as possible in the winter.
