The Functionality and Applications of Liquid Roofing
Liquid roofing, also known as fluid-applied roofing, stands as a robust technique for waterproofing and fortifying both new and existing roof surfaces with elastomeric roof coatings.
How Does Liquid Roofing Work?
Liquid roofing systems are applied in liquid form onto roof surfaces and subsequently cure to form a seamless, UV resistant, and waterproof membrane. Essentially, these liquid roofs act as a protective shield, safeguarding roof substrates against the elements such as sunlight, rain, and other environmental factors.
Ideal for both flat and pitched roof constructions, liquid-applied membranes find suitability across a range of materials including metal, modified bitumen (mod bit), built-up roofs (BUR), EPDM, TPO, PVC, concrete, and spray polyurethane foam.
The liquid coating materials possess a thicker consistency compared to standard household paint. Formulated with enhanced elongation and tensile strength, they can expand and contract alongside roofing substrates without incurring damage or distortion.
Most liquid membrane roofing applications employ hydraulic airless sprayers or tank spreaders for installation, with occasional use of squeegees or nap rollers in specific scenarios.
The History of Liquid Roofing
While the concept of liquid roofing dates back centuries, its commercial viability emerged in the early twentieth century.
Initially, liquid roofs faced skepticism due to limited knowledge, inadequate training, high material costs, and supply constraints.
The advent of modern liquid coatings like silicones, acrylics, and polyurethanes in the 1960s and 70s marked a turning point. These materials underwent significant advancements over subsequent decades, laying the foundation for contemporary liquid membrane roofing systems.
The domestic manufacturing surge over time drove down costs and mitigated supply chain issues. Concurrently, roofing companies embraced liquid roofing practices, training their workforce accordingly. With liquid roofing demanding less-skilled labor compared to traditional tear-offs, companies found it economically advantageous.
The Great Recession of 2008 catalyzed liquid roofing's ascent. Amidst reduced new construction and renovation projects, roofing companies sought practical alternatives, leading to widespread adoption of liquid roofing. The cost-effectiveness and efficiency of liquid roofing appealed to both contractors and property owners, solidifying its position as a commercial roofing solution.
Today, liquid roofing stands as a flourishing segment in the commercial roofing industry, with major manufacturers offering diverse lines of liquid-applied roofing solutions.
Liquid Roof Coating vs. Liquid Roofing System
While often used interchangeably, the terms "liquid roof coating" and "liquid roofing system" bear distinctions.
Liquid Roof Coating:
Can function independently as a roofing solution, provided the roof is in good condition.
Enhances energy efficiency and extends roof life but isn't recommended as a long-term waterproofing solution.
Liquid Roofing System:
Operates on a different level of waterproofing, involving reinforcement of roofing substrates with bonding agents, mastics, sealants, and/or fabric inlays.
Offers superior moisture resistance, durability, and longevity through multiple elastomeric coating applications over the reinforcement layer.
Typically covered by long-term manufacturer warranties, unlike liquid roof coatings.
Types of Liquid Roofing Systems
Various materials underpin most liquid membrane roofing systems today:
Acrylic
Butyl (Butyl Rubber)
Silicone
PMMA (polymethyl methacrylate)
Polyurethane (Urethane)
Spray Polyurethane Foam (SPF)
Each material has unique properties and applications, catering to different roofing needs and preferences.
