Why Tarp a Roof with Sandbags?

Tarping a roof with sandbags is a proven temporary solution to protect your home from the elements. It can prevent further damage, reduce repair costs, and provide a quick fix until you can arrange for professional assistance. The combination of a heavy-duty tarp and sandbags ensures a secure and reliable seal, even in adverse weather conditions.

Materials You’ll Need

To tarp your roof with sandbags, you’ll need the following materials:

  1. Heavy-duty tarpaulin (size depends on the damaged area)
  2. Sandbags (approximately 20-30, depending on the tarp size)
  3. Ladder
  4. Utility knife
  5. Gloves
  6. Rope (optional)
  7. Safety harness (optional, but recommended)

Safety Reminder: Roof repair can be dangerous. Always take necessary precautions, such as using a safety harness and having a spotter to help with the ladder.

Step 1: Assess the Damage and Measure the Area

First, inspect the damaged area of your roof and take measurements. Be sure to cover the entire damaged section, extending at least 3 feet beyond the edges to provide sufficient coverage. This will help you determine the size of the tarp needed.

Step 2: Choose the Right Tarp

Select a heavy-duty tarpaulin that is large enough to cover the damaged area plus the 3-foot extension on all sides. Tarps come in various sizes and thicknesses, so choose one that is durable, waterproof, and UV-resistant for optimal protection.

Step 3: Prepare the Sandbags

Fill the sandbags with sand or an alternative material, such as gravel or dirt, and securely tie them closed. Ensure they are evenly filled and weigh between 30-40 pounds each for optimal stability. Prepare approximately 20-30 sandbags, depending on the size of your tarp and the extent of the damage.

Step 4: Place the Tarp on the Roof

With the help of a ladder and a spotter, carefully place the tarp on the roof, ensuring it covers the damaged area completely. The tarp should extend at least 3 feet beyond the edges of the damage. Make sure the tarp is smooth and wrinkle-free for a more effective seal.

Step 5: Secure the Tarp with Sandbags

Starting at the lower edge of the tarp, place the sandbags about 18 inches apart, ensuring they are evenly distributed along the perimeter. Continue placing the sandbags along the sides and the upper edge of the tarp. The weight of the sandbags will help secure the tarp in place, providing a temporary barrier against water and wind.

Pro Tip: If you’re concerned about the tarp lifting during strong winds, consider tying a rope around the sandbags and attaching it to a secure anchor point, such as a nearby tree or post. This will provide additional stability and security for the tarp.

Step 6: Inspect and Maintain the Tarp

Regularly inspect the tarp and sandbags, especially after heavy rain or strong winds. Replace any damaged sandbags and ensure the tarp remains secure and properly positioned. Remember, tarping your roof with sandbags is a temporary solution; make sure to schedule a professional repair as soon as possible.


Tarping a roof with sandbags is a practical and cost-effective temporary solution for protecting your home from further damage due to leaks or inclement weather. By following our expert guide, you can quickly and effectively secure your damaged roof until professional repairs can be made. Keep in mind that this method is a temporary fix and should not replace proper repairs by a professional roofer.

Helpful FAQs for Tarping a Roof with Sandbags

What is the ideal tarp thickness and material for tarping a roof with sandbags?

A heavy-duty tarpaulin made from polyethylene or vinyl is recommended for tarping a roof with sandbags. These materials are waterproof, UV-resistant, and durable. The ideal thickness for a tarp should be between 10-16 mils, providing a balance between strength and flexibility.

Can I tarp my roof with sandbags by myself, or should I get help?

Tarping a roof with sandbags can be a challenging and potentially dangerous task, especially for those with limited experience or working on a steep or slippery roof.
