Roofing FAQs, answered by experts

There are two main types of roofing shingles: 3-tab and architectural. Architectural shingles cost more than 3-tab but offer a more unique look and can last longer. However, 3-tab shingles are lightweight and affordable, and many people use them for both patching roofs and installing new roofs. Ultimately, the best type for you depends on your budget and your home’s aesthetic.

The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.

A standard roof can hold a live load of about 20 pounds per square foot. However, gable roofs often have steeper-than-average slopes, so calculating their weight capacity can be challenging. If the slope of your gable roof is greater than 4:12, the live load needs to be decreased to allow for a larger dead load. Ask your roofer exactly how much weight your roof can support.

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.

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.
