You’re probably here because a new roof is expensive. When you have kids with braces, need to get the brakes fixed on your car or even have other outstanding expenses, you probably don’t want to foot the bill for roof repairs.

However, if you have the tenacity and the will to succeed, you may want to save on labor costs by repairing your roof yourself: DIY style.

For homeowners facing roof leaks, it can be tempting to use products like Flex Seal to stop the leak in its tracks. 

However, Flex Seal may not be as great as it seems. There are limits to what Flex Seal can do, and it’s not always the best option for your roof.

Rescue My Roof has been a leader in the roofing industry for over a decade, helping homeowners fix their roofs after DIY roof repairs.

If you’re debating on whether to attempt DIY roof repairs with Flex Seal, you’re in the right place. Here are the pros and cons of using Flex Seal on your roof to help determine if it’s the right course of action.

Top Three Things You Need to Know Before Using Flex Seal On Your Roof

Before you take the plunge and utilize Flex Seal to fix your roof leaks, here are some things you should know. 

1. Flex Seal May Not Fix Your Roof Leak

Flex Seal is a rubberized liquid that forms a watertight barrier. Because its purpose is to make things “waterproof,” it can be tempting to use Flex Seal to fix roof leaks.

However, Flex Seal is not the best option to repair roof leaks – and here’s why.

When homeowners find a roof leak, they assume the cause is directly above the affected area. 

Often, the cause of a roof leak isn’t the area directly above the water stain. This means that if you use Flex Seal on the area, it won’t solve your problem.

Instead, it will create the need for eventual repairs in the area the Flex Seal was used. 

If you’re experiencing roof leaks, the best course of action is to call a roofing contractor. They will be able to diagnose where the leak is coming from accurately. 

2. Flex Seal Can Cause Cosmetic Issues

While using Flex Seal might be tempting when you’re in a pinch, there are other factors to consider beyond “will it work?”

Flex Seal can cause cosmetic issues like discoloration on your roof.

Additionally, when you’re not precise with the application, you can overspray Flex Seal onto other surfaces like your siding.

This can be more difficult to fix because once the Flex Seal is there, it’s there to stay. There may be chemicals on the market capable of removing Flex Seal, but you may wipe away the color of your materials. 

3. You Will Eventually Need Roof Repairs Beyond Flex Seal

Flex Seal is a temporary bandage. While it may stop leaking now, you will eventually need to address it with a professional.

Additionally, Flex Seal can make professional repairs more difficult, as shingles may stick together, making removal difficult.

It will be more cost-effective in the long run to call a professional first to address any leaks. And, if you need to stop a leak now, you can put a tarp over the affected area until help arrives. 

Find the Right Contractor for Roof Repairs

Instead of Flex Seal, opt for professional roof repairs to avoid further issues. 

Finding the right contractor for repairs isn’t always easy. We recommend getting several estimates to determine the right contractor for you.
