What is the Purpose of a Roof Sealant Treatment?

Roof sealants provide an extra layer of protection from the elements. Sealants are important for flat roofs, which tend to collect water, but they’re optional for sloped roofs. In most cases, a sealant is applied to a sloped roof as it ages in order to extend the life and prevent leaks. This can buy time, but it’s not a long-term solution.

Generally, sealants also make your roof look newer and more attractive. If you’re selling your home or looking to boost curb appeal, sealing is something to consider. In some cases, sealants boost your home’s energy efficiency by reflecting light.

How Much Does a Roof Sealant Treatment Cost?

Generally, professional sealing costs anywhere from $200-$1,000. The price depends on the size and pitch of the roof, the type of sealant used and your location. Pitched roofs are more expensive to seal than flat roofs, and sealants with light-reflecting qualities for energy efficiency tend to cost more.

Before your roof is sealed, it must be cleaned. Sealant will not stick to a dirty roof. Cleaning is rarely included in the price of a sealing job, but just about every company will do it for an additional fee. Depending on the condition of the roof, cleaning could run a few hundred dollars to more than $1,500. If you’re looking to save a few bucks and know what you’re doing, consider tackling the job yourself.

Man Sealing a Flat Roof

A roof must also be inspected for damage before it is sealed. Sealant should never be applied to a roof that is in extreme disrepair. In some cases, an inspection will identify a few areas in need of repair before a sealant can be applied. Other times, it will bring to light that the roof has to be replaced. A basic inspection might be included in the price of a sealing job, and a more detailed inspection might cost $200-$300. If repairs are required or the roof is unsalvageable, you’re dealing with a different set of costs entirely. However, keep in mind that it’s always better to pay for an inspection and any necessary repairs before a rook leaf or collapse ruins your home’s interior.

Choosing a Reputable Roofer

The vast majority of roofing companies are honest, but a few bad apples have shed some negative light on the industry. Sealing is a necessity for some homeowners and a great option for others, but it’s certainly not for everyone. Here’s what you should know so you don’t end up paying for a sealing job you don’t need:

  • Never hire a company that knocks on your door saying they were “in the area and had extra materials.” These are almost always fly-by-night companies, and this tactic is almost always a scam.
  • If you have any doubt that your roof needs sealing, seek a second opinion. It never hurts to double check, particularly if you don’t have the knowledge to assess the condition of the roof on your own.
  • Always seek quotes from reputable, established companies. Look for companies with a website and a physical address. Ask for references and check the company’s record with the Better Business Bureau. Or, if you’re a member, use a trusted service like Angie’s List to find a company with good reviews.
