How Long Can You Leave A Tarp On A Roof​

A tarp offers a quick and efficient solution when a roof is damaged — whether by a storm, falling debris, or unplanned leaks. However, even though it’s effective at stopping leaks, it’s still a temporary measure, with many homeowners asking: How long can you leave a tarp on a roof?

To help you learn how long a tarp can be kept on your roof, we will explore this answer in close detail, considering different aspects so you can make the right decision for your roof.

How Long Does A Tarp Last On A Roof?

Depending on the material, weather, and quality of installation, a tarp on a roof may last anywhere around 90 days to 2 years. While heavy-duty choices like vinyl are more resilient and can endure tough circumstances for up to two years, standard blue tarps only provide temporary protection for up to 90 days.

What Are The Risks of Leaving a Tarp on Too Long?

While you might be able to keep a tarp on a roof for 2 years, it’s not recommended. Leaving a tarp on for too long can cause serious problems, so let’s explore the risks of relying on it as a long-term fix:

1. Material Breakdown 

Constant exposure to UV rays, wind, and rain weakens the tarp, leading to tears, holes, and thinning, which reduces its ability to protect the roof.

2. Water Leaks

As the tarp on a roof wears down, it may start letting water seep through, leading to leaks and further interior damage.

3. Structural Damage 

Relying on the tarp for too long can delay necessary repairs, allowing roofing problems to worsen and increase repair costs.

4. Mold and Rot 

Trapped moisture under or around a worn-out tarp on a roof can lead to mold growth and wood rot, weakening the roof’s structure.

5. Pooling Water 

If the tarp on a roof is sagging or not secured properly, it can collect water, putting extra stress on the roof and increasing the risk of damage.

6. Higher Repair Costs 

The longer you rely on a tarp on a roof, the longer damage is left to get worse, leading to more extensive and expensive repairs later on.

7. Safety Hazards 

A damaged or loose tarp on a roof can be dangerous in storms or high winds, as it may detach and pose risks to people and nearby structures.

8. Poor Insulation 

Putting a tarp on a roof doesn’t provide proper thermal protection, which means that if you fail to repair materials that aid in energy efficiency, a tarp won’t stop you from paying higher energy bills and dealing with discomfort during extreme weather.

What Are The Different Factors That Affect How Long a Tarp Can Stay on Your Roof?

You may be wondering why the range is so wide for leaving a tarp on your roof. This is due to a few factors that impact how long a tarp remains effective on your roof:

1. Material Quality

The type of material determines how long a tarp lasts. Heavy-duty tarps made from vinyl or UV-resistant fabric handle harsh weather better than basic polyethylene tarps, which break down faster when exposed to sun and moisture.

2. Weather Conditions

Extreme weather affects how well a tarp holds up. Too much sun can make it brittle, heavy rain or snow can weigh it down and cause sagging, and strong winds may tear or loosen it if not secured properly.

3. Installation Matters

A tarp’s durability depends on how well it’s installed. A properly secured tarp that is tightly fastened to the roof will hold up better against wind and water than one that is loosely placed or poorly sealed.

How To Tarp A Roof Without Nails

If you’re wondering what is the best way to put a tarp on a roof without nailing it into place and creating more holes, here’s a simple step-by-step guide to help you do it right:

Bungee CordsUtility Knife
SandbagsBrush or Broom
Ladder and Safety HarnessHeat Gun (optional)

Step #1. Ensure Safety First

Before starting, check the weather and make sure it’s safe to work. Wear non-slip shoes, use a roof harness if possible, and set up a sturdy ladder on stable ground to avoid accidents.

Step #2. Inspect the Roof

Look for damaged spots where leaks may occur. Clear away dirt, debris, and broken shingles to create a clean, dry surface for installing the tarp.

Step #3. Pick the Right Tarp

Measure the damaged area and add a few extra feet on all sides for full coverage. Choose a strong, weather-resistant tarp on a roof, ideally one with a self-adhesive backing or suitable for alternative securing methods.

Step #4. Position the Tarp Properly

With help, spread the tarp over the damage, making sure it extends at least 4 feet beyond the affected area on all sides. This extra coverage keeps water from seeping underneath.

Step #5. Secure Without Nails

If using a self-adhesive tarp, peel off the backing and press it firmly onto the shingles. Otherwise, use tarp clips and bungee cords to fasten it to sturdy points, or place sandbags or 2x4s along the edges for extra weight and stability.

Step #6. Check for a Tight Fit

Smooth out any wrinkles to prevent water from pooling, which can lead to leaks. Double-check that all edges are secure so the tarp can withstand wind and rain.

Step #7. Plan for Permanent Fixes

A tarp is only a temporary solution. Once it’s in place, schedule repairs with a professional roofer as soon as possible to avoid further damage.

Alternatives to a Tarp for Roof Protection

If a tarp isn’t the best option for your roof, here are some alternative solutions for temporary protection:

1. Professional Emergency Roofing Services

Bringing in professionals ensures that temporary solutions like tarps or sealants are properly installed, preventing further damage. With the right tools and expertise, they can assess the situation and prepare your roof for long-term repairs.

2. Temporary Roof Sealants

For small leaks or cracks, roofing cement and silicone-based sealants create a waterproof barrier, offering immediate protection. However, these are only short-term fixes and should be followed up with professional repairs to maintain the roof’s strength.

3. Roof Repair Patches

Using materials like shingles, specialized tape, or roofing cement, patches can temporarily seal holes or leaks. While they help prevent further damage, they should eventually be replaced with permanent repairs for lasting protection.
