Bitumen roofing systems
Our long-established and fully integrated roof systems incorporate SBS modified elastomeric bitumen membranes and highly efficient PIR insulation and holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs and feature torch-free and torch-safe installation techniques for detailing on, or adjacent to combustible materials.
Bituminous membrane roofing systems are durable and long lasting. They are suitable for commercial and refurbishment building projects. We have seven systems within our bituminous membrane portfolio – Bauder Total Roof System PLUS, Bauder Total Roof System, Bauderflex, Airtech, Pro F, THERM ‘Stripes’ and Torch-free detailing. All are suitable for roofs of various shapes and sizes including green roof projects. Contact Bauder’s team of specialists, they will be able to tell you which is advisable.

Why bituminous systems?
A key advantage of bituminous roofing membrane systems is the exceptionally long lifespan. They require little upkeep over the years, although annual maintenance is recommended to extend its lifespan. These build ups can sustain heavy foot traffic as well as loads associated with installation and maintenance and permanently sited rooftop plant.
Bauder works hard to ensure all products meet the latest criteria for various accreditations.
Bauder Total Roof System PLUS
Installation and maintenance
These systems are installed using a few different methods. Self Adhesive Bitumen installation involving heat-activated 'DUO' technology, hot air welding techniques or adhesive bonding with PIR flat board insulation to provide solutions that are durable, resilient to the natural elements and give excellent fire resistance. Bauder Approved Contractors are the only people fully trained and certified to install our products, providing the necessary experience that our exceptional guarantee demands.
To keep the roof in prime condition, practical maintenance should be carried out. This includes:
- Cutting back tree limbs that overhang the roof to give a 1 metre clearance outside the roof edge. This will significantly reduce blockage of drainage ways due to fallen leaves.
- Removal of any vegetation growth that may have occurred, taking care not to damage the waterproofing.
- Ensuring that any items of plant/equipment that may have been introduced to the roof are sited on suitable isolated slabs, with additional surface protection beneath, and that any fixings that may have been used to secure them, do not penetrate the waterproofing.
Green credentials
Bituminous roofing systems can be used for green roof build ups with a root resistant cap sheet which stops the roots from penetrating the waterproofing system. The membranes are made from bitumen and polyester.
The BRE Green Guide to Specification gives our bituminous systems various generic ratings, depending on the type of deck construction and the support structure used. You can view the various different ratings in our Bitumen Systems Brochure.
Within our bitumen membrane waterproofing systems we have the following EPD certificates for our membranes and PIR insulation:
- Bitumen Membranes S-P-00414
- PU Insulation - Mineral Fleece Facing EPD-IVP-20140206-IBE1-EN
- PU Insulation - Aluminium Facing EPD-IVP-20140207-IBE1-EN
Our products in practice: we are committed to reducing the impact our manufacturing has on the environment as well as how our products can support the environment through the reduction of energy usage, recycling and reusing.
The
BauderPIR insulation has extremely high thermal efficiency and is CFC and HCFC free. It has zero ODP. As part of our PIR insulation manufacturing process, offcuts and waste are readily recycled and used in the production of hand cleansers and decking materials.
Bitumen is the primary raw material used in the production of bituminous waterproofing membranes. It is a byproduct of oil refining and is essentially the waste material of this petrochemical process and therefore has little additional detrimental effect on the environment.
We utilise a shredder to recycle any offcuts, and waste bituminous membranes back into production. When roofs are replaced, the bituminous layers can be incinerated for heating and electricity production
Which system is right for my project?
Get in touch with Bauder’s team. Our experts can help you choose between our six bituminous membrane systems.
- Bauder Total Roof System PLUS is Bauder's premium waterproofing system, utilising the latest manufacturing technology for a dual formulation capping sheet. It is suitable for use in both refurbishment and new build projects particularly when long life-span and high durability are required.
- Our Bauder Total Roof System is suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios. There is also the option of using a root resistant cap sheet, making this waterproofing system ideal for green roof situations.
- Bauderflex is resistant to European climatic conditions, and resists impact and tearing. It satisfies requirements of Part B of Building Regulations, and can be used in warm and cold roof designs and to overlay existing roofing materials.
- Airtech is a 4.2mm thick elastomeric bitumen membrane that withstands loads of up to 2000Kg/m2. The system can be used as a full system build-up or for detailing purposes only where Torch-Free application is a requirement.The reinforcement used in the capping sheet is made from recycled polyester.
- Pro F is designed to be installed on flat roofs with a minimum fall of 1:60 (1 degree) and roofs with slopes up to 25°. It is 5.2mm thick and withstands climatic extremes of over 100⁰C variation. The fire retardant prevents external spread of flame.
- THERM ‘Stripes’ is only suitable for refurbishment projects.This system can overlay the existing system to extend the life expectancy of the roof by at least 15 years.
Our
torch-free detailing is integrated into all the Bauder bituminous waterproofing solutions, including Bauder hot melt, to give versatile safe installation techniques for all roof types, site conditions and the client’s budget.
