How to Tarp a Roof After Storm Damage

When a storm, heavy rain, or fallen tree damages your roof, acting quickly is essential to prevent water from entering your home and causing costly interior damage. A roof tarp offers a temporary waterproof barrier, protecting your property until proper repairs can be carried out.

This guide explains how to safely and effectively tarp a roof in Australian conditions, including what tools and materials you’ll need, how to secure the tarp correctly, and when it’s best to call in a professional roofer.

Why You Might Need to Tarp Your Roof

Roof tarping is often the first line of defence after unexpected roof damage, especially following Australia’s unpredictable weather — from intense summer storms and heavy rain to falling branches and strong winds. When a roof is compromised, even a small exposed section can allow water to infiltrate ceilings, walls, and insulation, leading to mould growth, structural decay, and expensive repairs.

Applying a tarp provides an immediate, temporary barrier that protects your home from further damage while you arrange for inspection, insurance assessment, or full repair. It’s a practical solution that can save homeowners thousands in restoration costs and give peace of mind during the stressful aftermath of a storm.

Common situations where roof tarping is essential include:

• Storm or wind damage – when tiles, shingles, or metal sheets have been dislodged or lifted.
• Fallen debris – such as tree limbs puncturing or cracking the roof surface.
• Active roof leaks – allowing rainwater to seep into interior spaces.
• Pending repairs or insurance claims – when permanent work cannot start immediately.

Whether you’re facing a small leak or extensive damage, a properly installed tarp helps protect your property, buy time, and prevent minor issues from turning into major repairs.

Safety First: Before You Begin

Before climbing onto your roof, it’s crucial to prioritise safety above all else. Roof tarping often takes place in the aftermath of storms, when surfaces are slippery, winds are unpredictable, and roof structures may already be weakened. Even a minor misstep can lead to serious injury or further property damage. Taking the right safety precautions not only protects you but also ensures the tarp is installed securely and effectively.

• Wear non-slip shoes, safety gloves, and a roof harness.
• Use a stable ladder on level ground and have someone assist or supervise.
• Avoid working during bad weather or in strong winds.
• If the roof appears structurally unsound, do not attempt to climb on it.
• For steep or high roofs, it’s best to contact a professional roofer for assistance.

Tools and Materials You'll Need

Before getting started, gather these essential tools and materials:

• Heavy-duty, UV-resistant tarp (preferably poly or vinyl)
• Roofing nails or screws designed for outdoor use
• Timber planks or battens (to secure tarp edges)
• Sandbags or tie-downs (to prevent movement in windy areas)
• Ladder, tape measure, utility knife
• Personal protective gear (harness, gloves, helmet, non-slip footwear)

Choose a tarp size that extends 300–600 mm (1–2 feet) beyond the damaged section on all sides for complete coverage.

Step-by-Step Guide: How to Tarp a Roof

Step 1: Assess and Measure

From the ground, identify the affected area and estimate the size of tarp required. Avoid climbing onto unstable or slippery sections.

Step 2: Clear and Prepare

Remove loose debris like branches, leaves, or broken tiles. Ensure the roof surface is clear so the tarp can lie flat.

Step 3: Position the Tarp

Unfold the tarp and carefully place it over the damaged section, ensuring both sides overlap evenly across the ridge and eaves.

Step 4: Secure the Top Edge

Wrap the top edge of the tarp around a timber plank or batten, then screw the plank into the roof structure. This helps seal the ridge and prevents water from running underneath.

Step 5: Fasten the Sides and Bottom

Pull the tarp tight and repeat the same process along the sides and bottom edges. Secure with additional planks or sandbags for wind resistance.

Step 6: Inspect and Maintain

After installation, check the tarp regularly, especially after rain or strong winds. Tighten any loose fasteners and ensure the tarp remains securely in place.

When to Call a Professional

While DIY tarping can be effective for small or easily accessible areas, professional help is strongly recommended when:

• The roof is steep, high, or unsafe to access.
• Damage is widespread or structural.
• There’s continuous water entry despite tarping.
• You need documentation for insurance purposes.

Professionals have the proper tools, safety equipment, and experience to secure your roof quickly and safely — often in conditions that would be risky for homeowners.

Typical Costs and Time Frames

• DIY materials: $100–$300, depending on tarp quality and roof size.
• Professional tarping service: $350–$800 on average.
• Time required: Around 1–2 hours for DIY; often under an hour for trained roofers.

Although tarping is a temporary measure, it can save thousands of dollars in interior water damage, making it a smart short-term investment.
