Materials Needed for Tarping a Roof with Sandbags

Sandbags are another crucial component. Opt for sturdy, high-quality sandbags that can withstand harsh, inclement weather conditions. You’ll also need sand to fill the bags, although some suppliers offer pre-filled sandbags for convenience.

Steps to Tarp a Roof with Sandbags

Let’s delve into the full step by step instructions and process to tarp your roof with sandbags.

1. Assessing the Damage and Safety Measures

Firstly, assess the roof damage to determine the size of the tarp needed. This should be done cautiously. 

Make use of a stable ladder to reach the rooftop safely. Ensure you’re wearing non-slip shoes and work gloves to protect your hands and ensure a firm grip. 

Examine the roof for holes, missing shingles, and other signs of damage.

If the roof appears unstable, or if you’re uncomfortable with heights, consider hiring a professional. 

Their expertise will ensure a thorough assessment and can potentially prevent further damage or injuries.

2. Preparation of the Tarp

After assessing the damage, you’ll need to measure the area in order to cut the tarp. The tarp should cover the damage and extend beyond it by at least 3 feet on all sides. This will ensure that clear debris in the area is well-protected and the tarp is properly secured by the sandbags.

When cutting the tarp, use a sharp utility knife for a clean cut, reducing the likelihood of tearing. 

Always cut the tarp on a flat, stable surface, and be mindful of your surroundings to avoid injury.

3. Installation of the Tarp

Smooth out any wrinkles or bubbles as these can catch wind and potentially dislodge the tarp.

In addition, you may want to reinforce the center of the tarp with a few additional strips of adhesive, especially if the damaged area is large. This will help prevent the tarp from sagging under the weight of accumulated rainwater or snow.

4. Preparation and Placement of the Sandbags

Next, prepare the sandbags. Use a sturdy scoop or shovel to fill them with sand until they are about two-thirds full, then tie them securely. 

Make sure each sandbag is tied tight enough to prevent sand from spilling out, but not so tight that the bag can’t conform to the shape of the roof.

Place the sandbags along the edges of the roof peak the tarp, starting from the bottom and working your way up. The narrow end of each sandbag should face either up or down the slope of the roof.

5. Final Inspection

Once all the sandbags are in place, conduct a final inspection. Check the tarp and sandbags to ensure they’re secure and cover the damaged area effectively. 

Make any necessary adjustments, adding or repositioning sandbags as needed.
