Use this SimpleSpecs™ 3-part specification template to specify fluid-applied roofing applied over solid concrete or plywood decking.
What is it?
Fluid-applied roofing is a type of roofing system applied as a liquid, typically using a roller or a sprayer. It’s applied over solid concrete or plywood decking and forms a seamless, monolithic membrane resistant to water and air infiltration. An easy-to-install system; applied to various surfaces and is relatively durable and long-lasting. Additionally, fluid-applied roofing can be used to repair or restore existing roofs, which can be more cost-effective than a full replacement.
Fluid-applied roofing systems can be made from various materials, but single-component polyurethane and silicone roofs are two of the most common types.
- – Single-component polyurethane roofing systems are made from a one-component mixture of polyurethane resin. These systems are typically applied in one coat, which is self-leveling and forms a flexible, waterproof membrane. Single-component polyurethane roofing systems are typically used in low-slope roofing and are resistant to UV, ozone, and temperature changes. They are a great option for restoring and repairing existing roofs and new construction.
- – Single-component silicone roofing systems are made from a liquid silicone rubber that is applied to the roofing substrate in one coat. Once cured, the silicone forms a waterproof and flexible membrane. These roofing systems are typically used for flat or low-slope roofs and are resistant to UV, ozone, and temperature changes and to ponding water, which can be an issue in low-slope roofing. They have good flexibility which is ideal for buildings that experience movement. Single-component silicone roofing systems are easy to apply and do not require a primer, making them more cost-effective than multi-component silicone roofing systems.
Single component polyurethane and silicone roofing systems are relatively easy to apply, making them more cost-effective than multi-component systems. They are ideal for the restoration and repair of existing roofs, as well as for new construction. They are also durable and long-lasting roofing systems, but it’s always important to consult with a professional to determine if one of these options is the best choice for a specific building.
How long will it last?
The lifespan of fluid-applied roofing applied over solid concrete or plywood decking can vary depending on various factors. The quality of the materials used, the skill of the installer, and the conditions to which the roof is exposed. Generally, a well-installed fluid-applied roofing system can last between 10 to 20 years. However, some systems can last even longer, up to 25 years or more, depending on the specific materials used and the conditions of the roof. Regular maintenance and inspections can also help extend the roofing system’s life.
