Understanding the Weight of Shingles

The weight of shingles can vary significantly based on the type and material used. Generally, roofing shingles are categorized into three main types: asphalt, wood, and metal. Each type has distinct characteristics, including weight, which can influence installation processes and structural considerations of the roof.

Asphalt shingles are among the most commonly used roofing materials due to their affordability and ease of installation. On average, asphalt shingles weigh between 200 to 240 pounds per square (where a square equals 100 square feet). Here is a breakdown of the weight per square for different types of asphalt shingles:

  • 3-Tab Asphalt Shingles: Approximately 200-220 pounds per square
  • Architectural Asphalt Shingles: Approximately 220-240 pounds per square

Wood shingles and shakes are another popular option, often chosen for their aesthetic appeal. However, they are heavier than asphalt shingles. The weight of wood shingles can range from 300 to 400 pounds per square, depending on the type of wood and thickness.

Metal shingles present a lighter alternative, generally weighing between 50 to 150 pounds per square. This makes them easier to handle and install, while still offering durability and resistance to various weather conditions.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
