The low pitch on flat roofs means they are prone to leaks. The damage caused can go unnoticed for long periods of time, as it affects the concealed structures directly beneath the roof. This also means repair is extremely expensive, and can significantly inconvenience the residents or business within the building.
A variety of membranes are used to help waterproof flat roofs, but these often require a lot of maintenance. Without proper upkeep, they are prone to penetration by rainwater, as well as sun damage and fungal growth. Resulting rot or blowing of brickwork means a full roof replacement may be required, at huge expense.
Many proprietors are starting to see the benefits of liquid roofing, a process that creates a durable, seamless watertight seal on flat roofs. Unlike felt and tar, little maintenance is required, reducing the risk of failure while saving the business time and money.
For example, liquid coating specialist Tor Coatings offers products that guarantee waterproofing for up to 25 years. This is certified by the leading approvals house the British Board of Agrément (BBA), so customers are assured of longevity.
Liquid roof coatings are also far easier and safer to install, as they are applied cold. This makes the organisation and execution of adopting this technology quicker and cheaper, and ensures early resistance to rainfall. And despite creating a watertight seal, these products are breathable to allow any condensation to escape, so internal damp is less likely to harm the roof.
As they are suitable for a variety of substrates, and can be used to repair existing damage, liquid coatings are the ideal option for most flat roof projects. Plus, products are available with other features such as UV protection and heat insulation, so proprietors don’t have to compromise.
