How Much Does a Bundle of Roofing Shingles Weigh?
When replacing your roof, there are several factors to consider, including the maximum weight capacity of your roof structure. Every structure has a distinct threshold for the amount of weight it can support, which can significantly differ from one building to another. Investing in a new roof is a big deal, so it’s important to work with an experienced roofing company that can help you choose the right roofing material for your needs and budget – including a material that is appropriate for your structure’s weight limit.
At Skyline Roofing, our roofing experts are ready to help you determine the best roofing material for your roof installation. We calculate the roof load capacity based on the building’s design, materials used, and the local building codes. Most roofs can hold at least 15-20 pounds per square foot, but the purpose of the structure will determine how sturdy it needs to be. Reach out to us with any questions; we are here to help!
What are the Three Main Types of Materials Used for Roofs in the Pacific Northwest?
There are many different types of roof shingles to choose from when it comes to replacing your roof. In the Pacific Northwest, where the climate tends to be wet and cool, the three most common types of roofing materials used are:
- Architectural Asphalt Shingles
Architectural asphalt shingles are popular in the Pacific Northwest due to their many design options, durability and ability to withstand the region’s rainy and windy conditions. They offer better resistance to moisture, wind, and algae growth compared to traditional three-tab shingles. Architectural shingles deliver an aesthetic appeal and they can be manufactured to effectively mimic the look of a wide range of roofing materials including tile, wood shakes, and slate.
Architectural shingles differ from standard three-tab shingles in that they are constructed from multiple layers of asphalt-coated fiberglass mat. It’s what gives them their dimension and aesthetic appeal. The dimensional design of architectural shingles adds visual interest to roofs, which is appreciated in the area’s diverse architectural styles. At Skyline Roofing, we prefer Malarkey’s Roofing shingles.
2. Three-Tab Asphalt Shingles
Three-tab asphalt shingles were the commonly used shingle type prior to development of architectural asphalt shingles. People opt for asphalt shingles due to their affordability, ease of installation, and reasonable durability against the elements. Three-tab shingles strike a balance between cost and quality, offering homeowners a cost-effective roofing solution that still provides reliable protection and a wide range of design options to suit various preferences.
Three-tab shingles are less expensive than architectural shingles because they are made of a single layer of asphalt-coated fiberglass as opposed to the multiple layers in architectural asphalt shingles. Unfortunately three-tab shingle manufacturing is being phased out due to the popularity and demand for architectural asphalt shingles. Overall, three-tab asphalt shingles make an efficient and durable roof at a lower cost.
3. Metal Roofing
Metal roofing has gained popularity in the Pacific Northwest due to its high durability and resistance to algae and moss build up. Metal roofs can effectively shed rain and snow, making them suitable for the region’s wet climate. The primary benefit of metal roofing is its longevity. Metal roofing has a longer life-span than asphalt shingles and is a lighter weight material than shingles. Additionally, metal roofing materials often contain recycled content and are recyclable at the end of their lifespan, aligning with the region’s emphasis on sustainability. Metal roofs come in various styles, including standing seam panels and metal shingles, offering versatility in design options for homeowners in the Pacific Northwest.
How Much Does a Bundle of Roofing Shingles Weigh?
To calculate shingle weight, we need to differentiate between bundles and squares. A square of shingles is a roofing term for 100 square feet of material. It typically takes three bundles of shingles to cover a square of roof. While both terms are used by roofers, bundle is more commonly used when talking about purchasing shingles, while square is more typically associated with a completed roof or shingle removal.
The weight of a square or bundle of roofing shingles can vary depending on the type and brand of shingles, as well as the quantity per bundle. It’s always best to check the manufacturer’s specifications for the exact weight of the specific shingles you are using.
For architectural asphalt, the average weight per square is 230-250 pounds and the average weight per bundle is 65-80 pounds.
For three-tab asphalt, the average weight per square is 150-180 pounds and the average weight per bundle is 50-60 pounds.
For metal roofing, the average weight per square is 140 pounds. Metal roofing is generally the lightest of these three options.
Why Shingle Weight Matters
There are several reasons why it’s important to know the weight of shingles:
- Roof load capacity. Knowing the weight of shingles is crucial for determining if a roof structure can support the added weight of the roofing materials. This is especially important for older or weaker structures where exceeding the load capacity could lead to structural damage or collapse.
- Safety precautions. Understanding the weight of shingles helps in planning safety precautions during installation. It allows workers to take appropriate measures to prevent injury and accidents, such as using proper lifting techniques and installing safety equipment like harnesses and scaffolding.
- Environmental considerations. Some municipalities have regulations regarding the weight of roofing materials to ensure that they do not exceed the load capacity of waste disposal facilities. Knowing the weight of shingles helps in complying with these regulations and properly disposing of old roofing materials.
