Everything you need to know about roof sealants

Is your roof leaking? Is it old, or falling apart? If you want to avoid paying thousands of dollars to a roof contractor in the near future, there is an easier and more affordable solution: roof sealants. A good roof sealant will bind to the surface of your roof in order to prevent water from leaking through. It will withstand intense cold, heat, wind, or rain, and will last for an incredibly long time.

Of course, not everybody knows about home repair. Fortunately, even the most inexperienced handyman can follow these easy steps. With that in mind, here are some of the most important things you need to know about roof sealants.


Leaks usually occur along the flashing of a roof. Roof flashing is the sheets of metal (or other material) that cover the angles and other features on your roof’s surface. When used and sealed properly, it is virtually impossible for water to seep through roof flashing.

Unfortunately, the seal between your shingles and flashing does not always hold up – particularly on older roofs. To find out how well your flashing is performing, climb onto your roof with a good can of roof sealant and take a closer look.


Now, go to various problem areas on your roof. Look for valley flashing, which can be found in areas where your roof changes grades and forms a valley. These areas are often marked by water damage, as this is where most water runoff flows. Carefully lift up the shingles that are close to the valley flashing, and spray your roof sealant approximately six inches underneath the edge of these shingles to ensure optimum leak protection.


Next, look at the vents and chimneys on your roof. There will be flashing around these areas. Lift up the flashing and place a generous dose of roof sealant between the vent pipe and the flashing. Take a similar approach with your chimney, but keep in mind that you may need to clear away some of the debris and caulk between the flashing and the chimney in order for your roof sealant to adhere properly.


Look for other problem areas on your roof, like a skylight or a dormer, and inspect the nearby flashing. Just like steps two and three, you need to gently lift the shingles and spray your roof sealant approximately six inches underneath.

You’re done! Using a roof sealant is that easy. Once that sealant dries, your house will be significantly more protected than it was before. Keep reading to find out how to use a roof sealant on other types of roofing material, and discover which kind of roof sealant works best for your home.

How to seal material other than shingles

Not every roof uses shingles. Ceramics, slate, and metal are also popular, and asphalt and wood shake shingles may require a special solution. Fortunately, the best roof sealants will stick to virtually any surface, and can easily be applied to any material. While the steps will be slightly different than those listed above, the process is essentially the same.

Simply go to the areas in which leaks could occur (or are already occurring) and liberally spray the roof sealant on the trouble spot. These problem spots can occur around drain spouts, chimneys, valleys, gutters, skylights, and other similar features. Unlike the steps listed above, you may not have to worry about gently lifting the shingles; instead, the seal will be right out in the open for you to spray.

Remember: when you use a roof sealant, fixing a leaky roof will be as easy as possible, no matter what material your roof is made out of. You can avoid the high cost of roofing contractors and prevent tens of thousands of dollars of water damage from occurring to your home.

What kind of sealant should I use?

There are plenty of different roof sealants out there. However, not all of them are very good. Unless you’re an experienced roof contractor, the easiest and quickest way to seal your roof is to use a simple spray sealer. Products like Flex Seal are becoming extremely popular due to their strength and durability, and cost a fraction of what a roofing contractor would charge.

In fact, at only $19.99 for two cans, Flex Seal is currently listed at an incredible bargain. It will last better than any other solution on the market, and can withstand even the most intense heat and cold. Since rubber doesn’t degrade naturally in the environment, this sealant will last for many years into the future, providing your house with comprehensive long-term coverage. As an experienced handyman, I have never seen a product that works as quickly and as easily as Flex Seal.
