Spray Foam Roof Maintenance Basics
With its debut in the US during the 1960’s, spray foam roofs have become the go-to choice for many commercial flat roof settings. It became popular due to its smooth roofing system that has no joints. This allows outside water and air to pass through and into the building for maximized insulation.
Installing the popular foam roofing system can be done with different shapes and types, whether it is installed for residential or commercial buildings, a foam roof is an eco-friendly roofing option. However, it is important to maintain your foam roof to avoid spray foam roofing problems.
Proper roof maintenance ensures your roof will last long into the future.
How Spray Foam Roofs Work
Another benefit is that spray foam roofs eliminate flashing leaks due to the way it adheres to the substrate when installed. This also reduces water accumulation in roofs and ultimately prevents water build-up, all while being lightweight and easy to re-roof compared to other conventional roofing systems.
In spite of having less material and reaching only 60 pounds per 100 square feet, it does not sag and provides as much, if not more, thermal resistance compared to traditional roofing systems. Additionally, it also has the benefit of being impervious to the harsh ultraviolet rays of the sun due to its elastomeric coating.
Of course, its lifespan and durability all depend on the quality of its maintenance. Fortunately, spray on roofs are generally easy to maintain. Any modifications can be done by in-house personnel for a friendly price. On that note, here is what you need to know about its upkeep.
When sprayed, the Spray Polyurethane Foam (SPF) expands and forms a solid layer across your existing roof. Not only does it look clean and appealing, but it also serves as excellent insulation against extreme weather conditions.
Once installed, a foam roofing system can last for more than 50 years. Yet, regular roof maintenance is still a requirement to ensure its long lifespan.
That said, below are four tips on how to maintain your foam roof system professionally.
Regular clean-up and upkeep of your foam roof
As with any roof type, regular cleaning is imperative to ensure that it can last for as long as possible. The same principle is true for your foam roofing system.
Thoroughly examine all signs of roof damage at least once every year, especially after any storm or heavy rain.
The roof’s terminal points can accumulate all forms of debris, such as fallen leaves, twigs, and even bird’s nests. These should be immediately cleared out as it will cause damage to the roofing material and reduce its lifespan if left unattended.
To remedy this, sweep the roof using a soft broom monthly to prevent any debris from getting trapped in the drains.
Dealing with a discolored and bad-textured foam roof
The next thing to consider for your maintenance is the color of your roof. It is important to know that any sign of discoloration on your foam roof is a sign of a bigger problem. These changes happen due to a reaction from an acidic substance in your roof. Any signs of stains should prompt immediate action.
During regular examinations, watch out for the roof’s texture as well. Make sure that the texture of the roof is the same at all places. Neat spray foams should feel as smooth and shiny as an orange peel, so any textural change should also call for repairs.
Getting rid of unnecessary objects
Another important consideration is how unnecessary objects can damage your foam roof. Spare parts, old furniture, unused HVAC, debris, and other similar materials should not be left on the foam roof. Also, keep heavy objects away from the roof so that you do not compromise the integrity of the foam.
Common repairs for your foam roofing system
It’s important to perform common repairs to ensure that your foam roofing system is in good condition. The commonly occurring problems in the spray foam roof are tiny holes and punctures, cracks and splits, or small blisters.
Due to the spray foam’s light material, it is easily susceptible to these irregularities. While it is highly coveted for its ability to prevent leaks, ruptures can lead to leakage and speed up the material’s deterioration.
When this problem is left untreated, the damage can result in homeowners having to reinstall the roof from scratch.
This can be fixed by applying a caulking material into the hole. To do so, cut out the damaged foam at a 45-degree angle before applying the caulk on the hole. Be sure to install a top coating, either acrylic or silicone, over the repair to fortify its durability.
Fortunately, repairing any punctures in its early stages can easily be done by an in-house worker.
Once installed, a foam roof can last for over 50 years. It doesn’t necessarily mean, however, that you can take it for granted. Regular maintenance is still paramount to ensure that it lasts longer. In fact, recoating is required to keep your foam roof in good shape and condition.
Follow the tips mentioned above, and you’ll ensure that your foam roofing system will last for as long as possible.
