How do you stop condensation on a metal roof?

This is often accomplished using vinyl-backed fiberglass insulation to prevent humid air from coming into contact with the cooler metal roof (which may be at or below the dew point).
What is the lowest slope for a metal roof?
The minimum slope for lapped, non-soldered seam metal roofs without applied lap sealant shall be three units vertical in 12 units horizontal (25-percent slope). The minimum slope for lapped, non-soldered seam metal roofs with applied lap sealant shall be one-half unit vertical in 12 units horizontal (4-percent slope).

It is best to choose a light color metal such as white, light bronze, beige, peach, light green or blue, if you live in a region that has a lot of sun and a hotter climate.
How do you calculate roof drop?
If you know the angle of the roof in degrees you can find the roof pitch by converting the angle in degrees to a slope, then finding the rise by multiplying the slope by 12. First, find the slope by finding the tangent of the degrees, eg. slope = tan(degrees). Then multiply the slope by 12 to get the rise.
What roof pitch is 30 degrees?
A 30° roof pitch is roughly the same as a 7/12 roof pitch. To convert from degrees to the American ratio: Find the tangent of the angle, tan(angle). This gives you the pitch of the roof.
Do you need to vent a metal roof?
