When it comes to roofing underlay, durability and performance are non-negotiable. Roofers face daily challenges balancing weather protection, ventilation, and installation efficiency. Roofshield® stands out as a solution that addresses these challenges head-on. At 196 grams per square metre, this roofing underlay offers enhanced weight and strength, making it a reliable choice for both traditional and modern construction projects.
In this post, we'll share why Roofshield® has become a trusted product for thousands of roofers, highlighting its key features and practical benefits on the job site.
Strong and Durable Roofing Underlay
Roofshield®’s weight of 196 grams per square metre gives it a robustness that many other underlays lack. This enhanced strength means it can withstand the rigours of installation and the elements without tearing or degrading. For roofers, this translates to fewer delays and less material waste.
The durability also supports a wide range of applications. Whether you’re working on a fully supported roof or an unsupported one, Roofshield® performs consistently. It suits both warm and cold-pitched roofs, offering flexibility across different project types.
Effortless Installation Saves Time and Costs
One of the biggest advantages we’ve noticed with Roofshield® is how it simplifies installation. Unlike some roofing underlays that require additional ventilation products, Roofshield® eliminates this need. This saves time on site and reduces overall project costs.
By removing the need for extra ventilation hardware, Roofshield® streamlines the roofing process. This is especially valuable on tight schedules or when working in challenging weather conditions. The membrane’s design allows it to provide immediate weather protection, even during installation phases, so you don’t have to worry about sudden rain or wind damage.
Exceptional Vapour Permeability
Roofshield® is among the most vapour permeable membranes available, with a vapour resistance of 0.065 MNs/g and an Sd-value of just 0.013m. This means it allows moisture to escape from the roof structure while preventing water ingress.
This vapour permeability is crucial for avoiding condensation build-up, which can cause damage over time. Roofshield® facilitates air movement and moisture diffusion, helping roofs dry out faster during construction and reducing the risk of mold or rot.
Certified and Trusted for Quality
Roofshield® has held BBA certification since 1996, making it the first membrane approved for use in cold, non-ventilated roofs. This long-standing certification reflects its reliability and performance under strict testing.
Additionally, Roofshield® has NHBC acceptance with a certified air permeability of 34.4m³/m² h.50Pa. This certification means it meets the standards required for NHBC-approved projects without needing additional high-level ventilation. For roofers, this ensures consistent specifications and fewer surprises during inspections.
Uniform Airflow Without Extra Ventilation
Roofshield®’s air permeability ensures consistent airflow through non-ventilated roofs. This uniform airflow matches the performance of roofs ventilated according to BS5250 standards but without the need for complex ventilation hardware.
This feature is a game-changer for roofers working on projects where ventilation options are limited or where aesthetics require minimal visible ventilation components. Roofshield® manages moisture effectively, maintaining the roof’s integrity and lifespan.
No Vapour Control Layer Required
Uniquely, the BBA certification explicitly states that Roofshield® does not require a vapour control layer (VCL) for non-ventilated cold-pitched roof constructions. This reduces material costs and simplifies the build-up of the roofing system.
Removing the need for a VCL also reduces the risk of installation errors related to vapour barriers, which can lead to condensation problems if not fitted correctly. Roofshield®’s design supports a safer, more straightforward roofing process.
Sustainable and Transparent Manufacturing
Roofshield® is manufactured in the UK and comes with an Environmental Product Declaration (EPD). This declaration provides full transparency on the product’s environmental impact, helping roofers and builders make sustainable choices.
Choosing Roofshield® supports environmentally responsible construction without compromising on performance or durability. This is increasingly important as building regulations and client expectations evolve towards greener practices.
Water Resistance
Rated W1 under EN13859-1, Roofshield can endure a water column of over a meter without leakage, providing temporary weather protection to the building envelope for up to 3 months when exposed.
BS5534 Compliance
Independently tested and compliant across the UK, Roofshield, without the need for high-level ventilation or a vapour control layer remains the simplest and most cost-effective method to meet regulatory standards.
Why Roofshield® Continues to Lead Roofing Innovation
Roofshield® has earned its reputation by consistently delivering on the promises of durability, performance, and ease of use. Thousands of roofers trust it for projects ranging from historical building restorations to modern construction.
Its combination of vapour permeability, air permeability, and certification approvals makes it a versatile choice that adapts to different roofing needs. The product’s ability to provide immediate weather protection and eliminate extra ventilation products saves time and money on site.
For roofers looking to improve installation efficiency while ensuring long-term roof health, Roofshield® offers a clear advantage.
