DIY Roll Up Tarp Door for Firewood Storage (Easy Build Hack)

Introduction: Weathering the Elements – Why a Roll-Up Tarp Door Matters

As someone who’s spent decades immersed in the world of wood, from felling towering trees to meticulously stacking firewood, I understand the constant battle against the elements. Rain, snow, and relentless sun can wreak havoc on your carefully seasoned firewood, turning months of hard work into a soggy, moldy mess. A well-protected firewood stash isn’t just about convenience; it’s about efficiency, safety, and ultimately, saving money. Properly dried firewood burns hotter, cleaner, and more efficiently, reducing creosote buildup in your chimney and minimizing the risk of chimney fires. This is where a DIY roll-up tarp door for your firewood storage comes into play. It’s a simple, cost-effective solution to protect your investment.

This guide will walk you through building your own roll-up tarp door, offering a detailed, step-by-step approach that even a complete beginner can follow. I’ll share my personal experiences, insights, and practical tips honed over years of working with wood, ensuring your firewood stays dry, seasoned, and ready to fuel your home.

Understanding the Need: Firewood Storage and Protection

Before diving into the construction, let’s understand why proper firewood storage is paramount.

• The Enemy: Moisture. Green wood, freshly cut, has a high moisture content (often over 50%). Burning green wood is inefficient, producing less heat and more smoke. Seasoning reduces this moisture content to around 20% or less, making it ideal for burning. Rain and snow reintroduce moisture, negating the seasoning process.

• The Science of Seasoning. Seasoning relies on air circulation to evaporate moisture. Stacking firewood off the ground and allowing airflow between the logs is crucial. Direct sunlight can also aid in drying, but excessive sun can also degrade the wood over time.

• Storage Location. Ideally, your firewood storage should be located in a well-ventilated area, protected from direct rain and snow. A south-facing location can maximize sunlight exposure, but a tarp door can help control the amount of sun and prevent excessive drying.

• The Role of the Tarp Door. A roll-up tarp door provides a flexible solution. It allows you to easily cover and uncover your firewood pile, protecting it from the elements while still allowing for ventilation. It’s also a relatively inexpensive and easy-to-build option compared to more permanent structures.

Key Terms and Concepts

• Green Wood: Freshly cut wood with a high moisture content.
• Seasoned Wood: Wood that has been dried to a moisture content suitable for burning (around 20% or less).
• Cord: A standard unit of measurement for firewood, typically 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet).
• Face Cord (or Rick): A stack of firewood 4 feet high and 8 feet long, but with a width less than 4 feet. The width is usually the length of the firewood pieces.
• Creosote: A flammable byproduct of incomplete combustion that can build up in chimneys, posing a fire hazard.
• Moisture Meter: A device used to measure the moisture content of wood.

Step-by-Step Guide: Building Your DIY Roll-Up Tarp Door

Now, let’s get our hands dirty! Here’s a detailed guide to building your own roll-up tarp door.

1. Planning and Design

• Assess Your Needs. Start by measuring the opening you want to cover. Consider the height and width of your firewood storage area. Add extra inches to each side for overlap. A common size for a firewood storage area is 8 feet wide and 4 feet high, so you might want a tarp that is 9 feet wide and 5 feet high to allow for overlap.

• Choose Your Tarp. Select a heavy-duty tarp made of polyethylene or vinyl. Look for a tarp with reinforced edges and grommets. The thickness of the tarp is measured in mils (thousandths of an inch). A 12-mil tarp is a good balance of durability and affordability. I’ve found that silver tarps reflect sunlight better, helping to keep the firewood cooler during the summer months.

• Design Considerations. Decide how you want the door to roll up. A simple roll-up system with ropes and cleats is the easiest to build. Alternatively, you could use a more sophisticated system with a roller and crank, but this will require more materials and effort.

2. Materials and Tools

• Tarp: Heavy-duty polyethylene or vinyl tarp, sized according to your needs.
• Lumber:
  • Top Rail: A piece of lumber (2×4 or 4×4) the same length as the width of your tarp. This will be used to attach the top of the tarp and provide support.
  • Bottom Rail: A piece of lumber (1×2 or 2×2) the same length as the width of your tarp. This will be attached to the bottom of the tarp to help it roll up evenly.
  • Side Rails (Optional): Two pieces of lumber (2×4 or 4×4) to create a frame for the tarp. This is optional but can provide extra support and a more finished look.
• Fasteners:
  • Screws: Wood screws to attach the lumber together.
  • Staples: Heavy-duty staples to attach the tarp to the lumber. A staple gun is essential.
  • Grommets (if needed): Extra grommets if the tarp doesn’t have enough for your needs.
• Rope: Strong rope (e.g., nylon or polypropylene) for rolling up and securing the tarp.
• Cleats: Two cleats to secure the rope when the tarp is rolled up.
• Tools:
  • Measuring Tape: For accurate measurements.
  • Saw: To cut the lumber to size. A circular saw or miter saw is ideal.
  • Drill: To pre-drill holes for screws.
  • Screwdriver: To drive in the screws.
  • Staple Gun: To attach the tarp to the lumber.
  • Hammer: To install grommets (if needed).
  • Utility Knife: To trim the tarp.
  • Level: To ensure the frame is level (if using side rails).

3. Constructing the Frame (Optional)

• Cutting the Lumber. If you’re building a frame, cut the side rails to the desired height and the top and bottom rails to the desired width.
• Assembling the Frame. Use screws to assemble the frame. Ensure the corners are square and the frame is level.

4. Attaching the Tarp

• Preparing the Tarp. Lay the tarp flat on a clean surface. If necessary, trim the tarp to the desired size using a utility knife.

• Attaching the Top Rail. Place the top rail along the top edge of the tarp. Fold the tarp over the rail and staple it securely in place using the staple gun. Space the staples evenly, about 2-3 inches apart.

• Personal Experience: I’ve learned the hard way that using too few staples can lead to the tarp tearing away from the wood in strong winds. Overlap the tarp generously when stapling to ensure a secure hold.

• Attaching the Bottom Rail. Place the bottom rail along the bottom edge of the tarp. Fold the tarp over the rail and staple it securely in place. The bottom rail will add weight to the bottom of the tarp, helping it to roll up evenly.

• Adding Grommets. If your tarp doesn’t have enough grommets, add extra grommets along the top edge for hanging or attaching to the frame. Use a hammer and a grommet installation tool to install the grommets.

5. Installing the Roll-Up Mechanism

• Attaching the Ropes. Attach two ropes to the bottom rail, one on each end. You can use screws, staples, or even tie the ropes directly to the rail. Make sure the ropes are long enough to reach the top of the frame and allow you to easily roll up the tarp.
• Installing the Cleats. Install the cleats on the frame or on the wall next to the firewood storage area. The cleats should be positioned so that you can easily wrap the ropes around them to secure the tarp in the rolled-up position.
• Testing the Roll-Up Mechanism. Test the roll-up mechanism by rolling up the tarp and securing it with the ropes and cleats. Adjust the position of the ropes and cleats as needed to ensure a smooth and secure roll-up.

6. Mounting the Tarp Door

• Attaching to the Firewood Storage Area. If you built a frame, attach the frame to the firewood storage area using screws or bolts. Make sure the frame is securely attached and level. If you didn’t build a frame, you can attach the top rail directly to the firewood storage area using screws or nails.
• Adjusting the Tarp. Once the tarp door is mounted, adjust the tarp as needed to ensure it covers the opening completely. You may need to trim the tarp or adjust the position of the ropes and cleats.

7. Alternative Roll-Up Methods

• Using a Roller and Crank. For a more sophisticated roll-up system, you can use a roller and crank mechanism. This will require a roller tube (e.g., PVC pipe or metal pipe), a crank, and brackets to support the roller. Attach the top of the tarp to the roller tube and use the crank to roll up the tarp. This method provides a smoother and more controlled roll-up.

• Case Study: I once helped a friend build a roll-up tarp door for his firewood storage using a salvaged awning roller. It was a bit more work to install, but the result was a professional-looking and easy-to-use door.

8. Safety Considerations

• Wear Safety Glasses: When cutting lumber, stapling, or using power tools, always wear safety glasses to protect your eyes.
• Use Caution with Power Tools: Follow the manufacturer’s instructions when using power tools. Be aware of the risks involved and take precautions to avoid accidents.
• Secure the Tarp Properly: Make sure the tarp is securely attached to the frame and that the ropes and cleats are strong enough to hold the tarp in the rolled-up position. A loose tarp can be a hazard in windy conditions.
• Consider Wind Loads: If you live in an area with high winds, consider reinforcing the frame and using heavier-duty materials.

Tool Specifications and Wood Type Selection

• Chainsaws: While not directly used in constructing the tarp door, the chainsaw plays a critical role in the firewood preparation process. For felling trees, a chainsaw with a 16-20 inch bar is generally sufficient for most homeowners. Brands like Stihl, Husqvarna, and Echo are known for their reliability and performance. When selecting a chainsaw, consider the engine size (cc), weight, and safety features.

• Axes: An axe is essential for splitting firewood. A splitting axe with a wedge-shaped head is designed for splitting logs along the grain. A maul is a heavier axe that is used for splitting larger logs. Brands like Fiskars and Gransfors Bruks are known for their quality axes.

• Log Splitters: For larger volumes of firewood, a log splitter can save a significant amount of time and effort. Hydraulic log splitters are available in various sizes, ranging from 5-ton models for homeowners to 30-ton models for commercial use. Consider the log diameter and length capacity when selecting a log splitter.

• Wood Type Selection: The type of wood you burn will affect the heat output and burning time. Hardwoods like oak, maple, and ash are denser and burn longer than softwoods like pine and fir. Seasoning time also varies depending on the wood type. Oak, for example, can take up to two years to season properly, while pine can be ready in as little as six months.

  • Oak: High heat output, long burning time, but can be difficult to split and takes longer to season.
  • Maple: Good heat output, moderate burning time, relatively easy to split.
  • Ash: Excellent heat output, burns cleanly, easy to split.
  • Pine: Low heat output, burns quickly, produces more smoke, but is easy to split and seasons quickly.

Drying Methods and Moisture Content Targets

• Air Drying: The most common method for seasoning firewood. Stack the wood off the ground in a well-ventilated area and allow it to dry naturally. This process can take anywhere from six months to two years, depending on the wood type and climate.

• Kiln Drying: A faster method for seasoning firewood. Wood is placed in a kiln and dried using heat and controlled humidity. Kiln-dried firewood typically has a moisture content of 20% or less and is ready to burn immediately. However, kiln-dried firewood is more expensive than air-dried firewood.

• Moisture Content Targets: The ideal moisture content for firewood is around 20% or less. Use a moisture meter to check the moisture content before burning. Simply insert the probes of the moisture meter into a freshly split piece of firewood. If the moisture content is too high, allow the wood to dry for a longer period.

Strategic Advantages and Benefits

• Cost Savings: Building your own roll-up tarp door is a cost-effective way to protect your firewood. A commercially available firewood shed can cost hundreds or even thousands of dollars, while a DIY tarp door can be built for a fraction of the cost.
