4 Essential Spray Polyurethane Roof Maintenance Tips

Spray Polyurethane Roofs (SPF) are a fairly new invention, but they have undoubtedly improved the condition of buildings around the world. SPF effectively seals the building from the elements, and even insulates sound. It is durable, easy-to-install, and cost-effective – with the right roof maintenance tips.

Like any other roofing type, however, it will still need some maintenance to keep its integrity for longer. This is because inadequate maintenance could result in clogged water drains, which can cause long term damage. When it comes to SPF roof maintenance, it’s always best to leave it to professional cleaners who will look for possible damage and execute immediate repairs to keep the damage from spreading.

If you want to keep your SPF roof in tip-top shape for many years to come, here are four roof maintenance tips to do so:

Use a pressurized washer

Pressurized washers, especially those rated at 3000 PSI, will take care of any stubborn debris like leaves, branches, or mildew on your roof. While it can be a hefty investment at first, having a pressurized water spray washer will make the task of cleaning off the dirt and grime from your roof, and freeing clogged roof drainage canals much easier. In doing so, make sure that you are not using anything higher than 3000 PSI, as pressurized water jets can be strong enough to damage the roof that you are trying to maintain.

Thoroughly inspect everything on the roof

Because roofs are rarely visited except during maintenance, they usually get filled with anything that flies in the air. Depending on your location, the roof and HVAC vents can get filled with leaves and branches. At times, the vents can even play host to a bird’s nests. Make sure to remove every stuck debris you find to ensure that there is nothing left that could cause problems in the long run.

Use detergents to remove oil and grime

Due to smoke mixing in with the air in busy cities, it’s not uncommon to see surfaces streaked with oil. While this in itself will probably not damage your roof, the resulting spillage from the cleaning that you do on the roof could ruin your building’s facade. To remedy this, clean the spills with detergent and clean water immediately. Also, do not let the water dry out because the longer you wait, the more difficult it will be to get rid of the stains. On top of that, avoid using stronger cleaning solutions as highly acidic and corrosive chemicals can cause damage to your SPF roof and incur substantial costs in repairs.

Hire professional SPF roof maintenance services

Although you may save on costs by doing the maintenance yourself, professional roof providers can handle the spot checks as they go about cleaning the roof. Additionally, if you do not have the expertise to look after your roof, they can also perform patch repairs as they see fit.


While SPF roofs are widely known to be cost-efficient and long-lasting, it’s not invulnerable. Performing these four simple roof maintenance tips regularly will surely help you extend the longevity of your roof. Meanwhile, the cost of professional maintenance will be dwarfed by the savings you incur in energy costs by using an SPF roof.
