Roof coatings have become a popular choice for building owners looking to extend the life of their roofs and avoid the high cost of total replacement. These coatings offer numerous benefits, such as cost savings, increased durability, and energy efficiency. However, like any other roofing solution, roof coatings can encounter issues if not properly applied and maintained. In this article, we will explore some common roof coating issues and provide valuable insights on how to identify and address them.
Inexperienced Roofing Installers
One of the primary factors that can lead to roof coating failures is the use of inexperienced roofing installers. It is crucial to hire trained and skilled professionals who have expertise in roof coating application. Inexperienced installers may make mistakes that can negate the roof warranty, compromise the roof’s ability to keep water out, and require costly rework.
To avoid issues caused by inexperienced installers, make sure to thoroughly vet the roofing companies you consider hiring. Look for companies with a proven track record and positive customer reviews. Additionally, ask about the training and certifications of their installers to ensure they have the necessary skills and knowledge to perform the job correctly.
Improper Roof Cleaning and Preparation
Another common cause of roof coating failures is improper roof cleaning and preparation. Many people mistakenly assume that applying a roof coating is similar to painting a wall. However, roof coatings, particularly silicone coatings, require thorough surface preparation before application.
The cleaning process should include power washing and intense scrubbing to remove all debris from the roof surface. If the surface is not adequately cleaned, debris can become trapped between the roof and the coating, preventing proper adhesion. Additionally, it is essential to address flashing locations, seams, and penetrations with a special flashing-grade roof coating to ensure a seamless and durable application.
To ensure proper roof cleaning and preparation, it is recommended to consult with a professional roofing contractor. They can provide guidance on the necessary steps and techniques to achieve optimal surface conditions for roof coating application.
Coatings Applied When They Shouldn’t Be
Timing is crucial when it comes to applying roof coatings. One common mistake is applying coatings when the roof is wet or has moisture-related issues. Roof coatings require a dry surface to ensure proper adhesion and performance. If moisture is present between the roof layers and the building structure, applying a roof coating can lead to delamination and eventual failure.
Before applying a roof coating, it is essential to conduct a thorough inspection to ensure there are no existing moisture issues or trapped moisture beneath the roof’s surface. Trained roofing professionals can use infrared scanning or other methods to detect any potential moisture problems that could compromise the coating’s effectiveness.
Low-Quality Manufacturers & Products
The influx of roofing manufacturers in the silicone roof coating industry has led to a wide range of product qualities. Some manufacturers prioritise cost reduction over quality, resulting in inferior products that do not deliver the expected performance and longevity.
When selecting a roof coating product, it is crucial to choose a reputable manufacturer known for producing high-quality coatings. Look for manufacturers that provide warranties and have a track record of customer satisfaction. Conducting thorough research and comparing spec sheets can help identify the best products in the market.
One manufacturer that stands out in terms of quality and warranty support is Gaco Western. They require a pre-roof inspection for warrantied projects and offer comprehensive coverage for any materials or labour needed to repair defective applications. Choosing reliable manufacturers like Gaco Western can significantly reduce the risk of coating failures.
While roof coatings offer many benefits, it is essential to be aware of the potential issues that can arise if not properly addressed. Hiring experienced roofing installers, ensuring proper roof cleaning and preparation, applying coatings at the right time, and selecting high-quality products from reputable manufacturers are crucial steps to avoid common roof coating problems.
By following these guidelines, building owners can maximise the lifespan of their roofs and enjoy the cost savings and energy efficiency that roof coatings provide. Remember to consult with professional roofing contractors and conduct thorough research before embarking on a roof coating project.
