You are in the Commercial Zone
Rubberseal is a leading provider of roofing systems for modular construction, offering innovative waterproofing solutions that align with the speed, precision, and performance demanded by off-site manufacturing. Our systems are designed to support the growth of Modern Methods of Construction (MMC), helping modular manufacturers, developers, and contractors deliver high-quality buildings—faster and more safely.
Whether you’re working in a factory environment or on-site, Rubberseal provides a range of cold-applied roofing systems that are flame-free, rapid-curing, and tailored for the modular construction process.
Why Modular Construction Needs Specialist Roofing Support
Modular construction is all about speed, accuracy, and reduced disruption. However, not all roofing systems are suitable for this environment. Traditional torch-on felt or hot-applied systems pose safety risks and are difficult to coordinate with production schedules.
Rubberseal bridges that gap by offering flame-free roofing systems that are ideal for:
- Off-site manufacturing
- On-site module finishing
- Refurbishment and new build modular projects
Our systems are fast to install, require no hot works, and offer seamless waterproofing—making them perfect for modular buildings in education, healthcare, housing, and commercial sectors.

Rubberseal provides a complete portfolio of modular roofing solutions, including:
-

A cold-applied, BBA-certified liquid waterproofing system ideal for factory or site application. Provides a seamless, flexible membrane that adapts to complex details and offers long-term durability. -
Liquiflex Ultra-PUMA
A high-performance PUMA roofing system designed for ultra-fast curing and exceptional weather resistance—perfect for modular construction where time and reliability are key. -
Elevate™ EPDM
A world-renowned EPDM roofing membrane that can be factory-installed or adhered on-site using cold-applied adhesives. Its flexibility, lifespan, and minimal seams make it a go-to choice for modular flat roofs.
