Metal roofs have a reputation for being noisy, but with proper installation and adequate insulation, they are not significantly noisier than shingle roofs. The type of metal used can affect the sound level; for instance, steel roofs are typically noisier than slate or asphalt tiles but quieter than aluminum. While some people find the sound of rain on a metal roof pleasant, you can take steps to reduce the noise. Installing a thicker underlayment, adding insulation between the roof and the house, or using acoustic tiles can effectively muffle the sound. The gauge (thickness) of the metal roofing can also contribute to sound dampening.

The best material for your shed roof depends on your budget and personal preferences. For instance, if you’re looking for the most cost-effective option, rolled roofing is your best bet. Just be aware that it only lasts for five to eight years. If you prefer something with a longer life span (and you’re willing to pay for that durability), consider slate shingles, which can last for hundreds of years.

Building an A-frame roof falls under the category of constructing a steep roof. While its structure is relatively simple, its height and requirements for more materials than a shallow roof design can increase its cost significantly. Expect prices for building an A-frame roof to hover around average to slightly above average.

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.
