• Stone-coated steel roofing provides an attractive look and benefits of metal roofing.
• Premium grade synthetic underlayment weighs about 38 pounds per 10 square roll.
• Ice and water shield or any underlayment should always have a smooth top surface.
• Ventilation is important for metal roofs to prevent condensation on the underside of the roof deck in the attic.
• Ridge vents, slant back turtle vents, square vents, and power vents are common ventilation products used on metal roofs.
• Strapping battens on the roof may not be helpful and can decrease wind resistance.
• Metal roofing is a low weight option and reduces the ultimate stress on a structure.
• Metal roofs can address all three types of heat transfer: radiation, conduction, and convection.
