I am debating on replacing my current roof with either shingles or metalI am wondering what would be the best option in terms of resale value and durabilityWhat 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 roofMy house was built in 1993 and it wasn't common to install ridge vents during that periodMy 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 shinglesThe house has gable vents on each sideIs 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 betterI am afraid that I may have to much heat lost during the winterAny thoughts? Thanks!!!!
The actual answer is C because, That is the heat energy lost is directly related to the shape of the objectHeat energy lost or gained is related to the specific heat capacity of an objectRemember, the amount of heat transferred mass x change in temperature x specific heatThe variables included only mass, change in temperature, and specific heat.
Good attic ventilation is important regardless of roof typeVentilation helps keep the home cooler in summerIt helps avoid dangerous accumulation of moisture and it helps avoid winter ice damsGood ventilation requires intake at the eaves usually and exhaustA ridge vent encourages the best distribution of fresh air throughout the attic and is very effectiveToday's metal roofs come in a wide variety of stylesSome of the lower end ones have exposed Fasteners which can require maintenance eventuallyBUt the better metal roofs have concealed Fasteners as well as allowance for the metal's thermal movementThey make incredibly lasting roof choicesI have had metal on all three of my homes and loved them allAlso as far as winter heat loss.you need to avoid that with insulation on the floor of your atticThe 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.
