Problems like leaks, cracks, and UV degradation not only jeopardise the structural integrity of a property but can also lead to costly repairs and downtime. Liquid roofing systems offer a reliable, cost-effective solution for many of these challenges.
Common commercial roof problems
Cracks and blisters: Flat or low pitched roofs are common in commercial properties. As existing waterproofing systems near the end of their working life, cracks and blisters can become more prevalent. Such defects can occur more readily when existing waterproofing membranes become brittle with age, and suffer more from the effects of thermal contraction and expansion cycles.
Water leaks: Rainfall in the UK is frequent and can wreak havoc on poorly maintained roofs. Water ingress can cause cause internal water damage, mould growth, and health hazards as well as more serious structural damage if left unchecked.
UV damage: Though often underestimated, UV radiation can degrade traditional some roofing materials, causing them to dry out, crack, or lose flexibility. The result is compromised waterproofing and reduced energy efficiency for the building.
Poor seams and joints: Many sheet type roofing systems rely on seams and joints, which are often the weakest points. Such details and upstands are inherently more difficult to waterproof. Different materials may be used to waterproof upstands and details, which in turn have different coefficients of thermal variation. This leads to increased stresses, resulting in an increased risk of water penetration.
Ponding water: Flat roofs frequently suffer from ponding water, where rainwater fails to drain adequately. This stagnant water accelerates material deterioration and increases the load on the roof structure.
How liquid roofing provides solutions
Liquid roofing is a modern roofing solution that addresses the above issues by offering a seamless, durable, and waterproof membrane. Applied as a liquid, this method is particularly suited to the unique demands of the UK’s commercial roofing sector. Here’s how it resolves common problems:
Seamless application elimates cracks and leaks: Liquid roofing creates a monolithic, seamless membrane that eliminates the weak points typically found in some roofing systems. With no seams or joints, the risk of water ingress can be reduced.
Hydrolysis resistance: The hydrolysis resistance of PMMA resin based liquid roofing materials means that they will not deteriorate in ponding water. Whilst removing the risk of ponding water is highly desirable, it can be difficult. This means they are well suited as part of Green or Blue roof build-ups. With some inherently root and rhizome proof too, they offer a waterproofing membrane that provides the toughest protection without added weight.
UV resistance: PMMA resin based liquid roofing systems are inherently UV resistant. This resistance helps to ensure their durability. This means sacrificial layers are not required as in some waterproofing systems.
Flexibility and dynamic crack bridging: Elastomeric properties for liquid membranes mean they can move as the building they protect does. Some, such as those from Triflex, have also been certified for dynamic crack bridging properties to BS EN 1504-2, providing reassurance for those under considerable stress such as large concrete reservoir roofs.
Cost-effective refurbishment: For aging commercial roofs, liquid roofing provides a cost-effective alternative to full replacement. With the right expertise and testing, they can be applied directly over existing membranes, reducing downtime and disruption while delivering a durable solution.
Why you should consider liquid roofing
Long-lasting durability: With a lifespan of 20+ years when properly maintained, reinforced liquid roofing systems offers excellent long-term value, especially for large commercial properties. Look for third party accreditation, such as that from British Board of Agrément (BBA) or European Technical Assessment (ETA or EAD).
Versatility: Suitable for a range of substrates including concrete, metal, and bitumen, liquid roofing systems can be tailored to meet the specific needs of different commercial applications. Look for a supplier that provides bespoke project specifications for long term solutions.
Ease of installation: Liquid roofing is typically applied quickly and efficiently, minimising disruption to business operations. Its ultra fast-curing nature makes it especially advantageous in the UK’s unpredictable weather conditions. Triflex PMMA resin-based systems can be rainproof in just 30 minutes, and cure in temperatures as low as -5°C at the details, enabling projects to be undertaken year round.
No hot works: Cold liquid roofing solutions offer rapid waterproofing without the need for hot works, boilers, gas torches or heat guns. Safe and secure, there’s no need for fire watches and can help satisfy insurers requirements for works too. This means buildings can remain in use and provides minimal disruption to your business.
