How to Properly Stack Shingles on a Roof

Asphalt shingles are typically delivered in bundles, and each bundle can weigh between 50 to 80 pounds. Proper stacking not only makes them easier to access during the job but prevents them from sliding, warping, or becoming a safety hazard.

Here’s how to stack shingles correctly on a pitched roof:

  • Lay bundles flat: Always keep shingle bundles lying flat—never upright or on their edge. This maintains their shape and avoids cracking.
  • Use roofing jacks or toe boards: These tools provide temporary flat platforms on sloped surfaces. They help you store the shingles securely in place without risking them sliding down.
  • Stack near the ridge: If the pitch allows, placing shingles near the ridge can help distribute weight evenly without affecting the structure.

Only Stack Shingles on Flat Surfaces Whenever Possible

One of the best practices is to avoid stacking shingles directly on the pitched part of a roof without a supporting flat surface.

Here’s why:

  • Slipping hazard: Asphalt shingles are coated with granules. When placed on a slope, these granules can act like tiny ball bearings, making the bundles prone to sliding—especially if the roof pitch is steep.
  • Structural strain: Concentrated weight in one area of a sloped roof can lead to damage or sagging over time, especially on older homes or roofs already weakened by age or water damage.
  • Worker safety: You don’t want a heavy bundle shifting underfoot or sliding off the roof. Using toe boards, roof brackets, or scaffolding can provide flat, stable areas for stacking shingles safely.

If your roof doesn’t have many flat spots, you can create temporary flat staging areas using platforms or scaffolding along the eaves.


The Dangers of Stacking Shingles in Heat and Cold

Weather plays a significant role in how and when you should stack shingles.

In hot weather:

  • Shingles can stick together or become soft, especially if they’re dark in color and exposed to direct sunlight.
  • If stacked too high or under too much pressure, the lower shingles can warp or distort, making them unusable.
  • They may also fuse slightly together due to the adhesive strips, which can lead to improper sealing during installation.

In cold weather:

  • Asphalt shingles become brittle and can crack under pressure if not handled delicately.
  • Freezing temperatures can make the adhesive on the shingles less effective, which can cause sealing issues once installed.

Best Practices:

  • Avoid overstacking in extreme temperatures.
  • Keep bundles in a shaded or protected area until they are needed.
  • If you must leave shingles on the roof, make sure they are covered with a tarp and secured against wind and weather.

Avoid Debris When Stacking Shingles

Stacking shingles on top of leaves, twigs, or even old shingle granules can cause uneven pressure and surface warping.

Here’s what you can do:

  • Clear the roof deck first. Before you start staging shingles, do a full sweep of the area.
  • Use a broom or leaf blower to remove small debris that can’t be seen easily.
  • Avoid stacking near gutters where debris tends to collect.

Even the smallest bit of debris can deform the shingles over time, leading to gaps or bumps in the finished roof. At S&K Construction and Remodeling LLC, we always inspect and prep the roof before placing materials to ensure nothing interferes with the quality of the job.


Tips for Safe and Efficient Shingle Storage

  1. Distribute bundles evenly: This helps avoid overloading any one section of the roof.
  2. Use caution near edges: Never store bundles too close to eaves or valleys where they may fall.
  3. Secure against wind: On windy days, even heavy bundles can be shifted. Tarp them down or use safety harnesses to keep them in place.
  4. Limit stack height: Avoid stacking more than 3-4 bundles high. Excess pressure can warp the bottom ones, especially in warm temperatures.
  5. Lift properly: Always use safe lifting practices when carrying bundles. They’re heavy and awkward, which can lead to back injuries.

Why Proper Stacking Protects Your Investment

Improper stacking can result in damaged materials, unsafe work conditions, and additional labor costs. Here’s how doing it right saves you money:

  • Prevents product waste: Warped or cracked shingles may not lay flat, leading to leaks and warranty voids.
  • Avoids delays: Damaged materials can slow down the job, especially if new materials need to be ordered.
  • Boosts long-term roof performance: Properly stored and installed shingles last longer and perform better against wind, rain, and ice.

If you’re hiring a contractor and you notice bundles haphazardly placed or improperly stored, that’s a red flag. A professional crew like ours at S&K Construction and Remodeling LLC always handles roofing materials with care.
