  • Preparing Your Roof

After you have repaired all the damaged parts, clean your roof properly with soapy water and a broom. And then rinse it with clean water. After that, you might have to come down so you can allow it to dry. It will dry faster when you have good weather conditions.

  • Primer And Detailer

After the water, you need an underlayment that will balance and hold the sealant coming. So, in this regard, you apply a primer and a detailer. You can apply them using your brush or roller. Apply it to all parts of your roof and then wait 2-3 hours for it to dry.

Applying Your Sealant

After the prerequisites, it's time to apply the sealant on your roof and make your roof last longer.

  1. Get your preferred roof sealant from the available store. But make sure it is quality and then recommended by your roofing contractor
  2. Open and mix your sealant using your stirrer or electric power drill. Generally, aside from quality, the thickness of your sealant will determine its longevity. So, if you want your roof sealant to last for a longer time, you have to increase its viscosity, and of course, it will cost you more money.
  3. Apply your sealant using a long brush or roller and then spread it to every part of the roof. You can also pour the sealant on the roof and use the brush to apply it effectively.

Roofing cement can serve as an alternative for roofing sealant. All you have to do is mix and batter the roofing cement and then apply it on your roof with a trowel.

After application,

Wait for it to dry. Not every sealant requires a long waiting time. Always read the manufacturer's direction to know if the sealant product you're using requires waiting after it has been applied and for how long you have to wait.

Apply an alcohol-based cleaner on your roof. Apply it on all parts of your roof. After that, seal it with roofing tape.
