Replacing a roof involves numerous considerations, and understanding the weight of shingle bundles is crucial for accurate planning and cost estimation. This is especially important when calculating the necessary dumpster size for debris removal or when transporting shingles yourself. This article delves into the factors influencing shingle bundle weight and offers insights for homeowners and contractors alike.
Understanding Shingle Bundle Weight: Quick Calculations
For a quick estimate: most modern architectural shingle bundles weigh between 60 and 80 pounds. Three-tab shingles are generally lighter, ranging from 45 to 60 pounds per bundle. These figures can help estimate the total weight of new shingles or removal debris. However, remember that these are just starting points, as several factors influence the final weight.
What is a Square of Shingles?
A “square” of shingles refers to the amount of material needed to cover 100 square feet of roof area. Roofing professionals use this term to estimate material requirements. For example, a 1,500 square foot roof is approximately 15 squares. Roofers often round up to account for waste, so a 1,650 square foot roof would be considered 17 squares.
Bundles per Square: A Key Factor
Generally, about 3 bundles of shingles are needed to cover one square of roofing. This number is essential for determining the overall weight of a roof square and accurately pricing a roof replacement project.
The exact number of bundles per square depends on the shingle brand and its coverage specifications. For instance:
- GAF Timberline HD Lifetime Architectural Shingles: Approximately 33.3 square feet per bundle, requiring 3 bundles per square.
- CertainTeed Landmark Moire Black Laminated Architectural Roof Shingles: Similar coverage, around 33.33 square feet per bundle.
- CertainTeed XT25 Timber Blend 3-tab Roof Shingles: Slightly less coverage, about 32.5 square feet per bundle, potentially requiring an extra bundle per square.
Remember, a single bundle doesn’t cover an entire 100 square feet to keep the weight manageable for handling and installation. Always check the label for precise coverage details.
Shingles in a Bundle: How Many?
The number of shingles in a bundle varies between 21 and 26, depending on the brand. Individual shingles are relatively small, and the bundle is designed to be easily lifted by most adults.
Weight of a Square of Shingles
One square of architectural shingles typically weighs between 180 and 240 pounds. Traditional 3-tab shingles are lighter, usually weighing between 135 and 180 pounds per square.
Here’s the calculation:
- Architectural shingles: 60-80 pounds per bundle x 3 bundles per square = 180-240 pounds per square.
- 3-tab shingles: 45-60 pounds per bundle x 3 bundles per square = 135-180 pounds per square.
Cost of a Bundle of Shingles
On average, a bundle of shingles costs between $35 and $42, although prices vary by brand and location. For example, GAF Timberline HD architectural shingles currently cost around $40 per bundle. With three bundles needed per square, the average shingle cost per square ranges from $105 to $126. Due to inflation, these prices are subject to change.
Pallet Weight of Shingles
A standard pallet can hold 42 bundles of shingles, resulting in a significant weight. A full pallet, with each bundle weighing 60 to 80 pounds, weighs between 2,520 and 3,360 pounds. One pallet covers approximately 14 squares of roofing. Larger roofs requiring two pallets can incur higher freight shipping costs.
Estimating Roof Replacement Debris
If you’re handling the roof replacement yourself, accurate debris assessment is crucial for smooth cleanup. Consider these factors:
Factors Affecting Individual Shingle Bundle Weight
Asphalt vs. Slate vs. Cedar Shake Shingle Weight
The material of your shingles significantly impacts the weight.
Slate Shingle Weight
Slate shingles are the heaviest, often exceeding 1,000 pounds per square due to their stone composition. Many slate roofs are over a century old. When ordering a dumpster for slate roof removal, opt for a larger size.
Wood Shingle Weight (Cedar Shake Roofing)
Wood shingle weight varies due to the natural, non-uniform material. Older roofs, particularly those installed decades ago, present weight estimation challenges. Wood shingles can range from 200 to 700 pounds per bundle, translating to 600 to 2,100 pounds per square. When estimating wood shingle removal weight, carefully assess the number of layers on the roof, as multiple layers are common.
Shingle Quality and Weight
Architectural shingles, known for their strength and durability, weigh more than three-tab shingles. Higher quality often equates to greater weight.
Differences Between Top Brands
The shingle manufacturer can also influence bundle weight. Refer to manufacturer specifications for precise details.
Dumpster Ordering Considerations
Variations in shingle type affect the overall weight of debris, but consider these crucial factors when choosing a dumpster size:
-
Number of Shingle Layers: Determine how many shingle layers are on your roof by inspecting the edges. Multiple layers significantly increase debris volume. Roofing companies often include 1-2 layers of removal in their estimates, but additional layers incur extra costs.
-
Damaged or Rotted Plywood Decking: After shingle removal, assess the plywood underneath for rot. Plan for at least 100 square feet of extra wood in your dumpster. Inspect your attic for signs of damage to anticipate additional wood debris.
-
Dumpster Company Surcharges & Weight Limits: Verify weight limits and potential surcharges with your dumpster rental company. Exceeding these limits can result in unexpected fees.
Conclusion
Understanding how much a bundle of shingles weighs is essential for effective roof replacement planning. By considering the factors outlined above, including shingle type, number of layers, and potential surcharges, you can accurately estimate debris volume and choose the appropriate dumpster size. This knowledge empowers homeowners to manage costs and ensure a smooth roof replacement process. Properly managing waste removal and shingle costs are important steps in securing a new roof. There are financing options available to help cover these expenses, allowing homeowners to proceed without immediate financial strain.
