Refurbishment flat roof solutions
Establishing the condition of the existing flat roof, identifying areas of concern and providing solutions to restore and repair flat roofs.
Specifying the right solution
For refurbishment projects, our range of waterproofing solutions can be used with some systems lending themselves to a particular project depending on the design, cost, additional sustainability focus, and life expectancy.
Our design team will support you through all the considerations required for evolving the roof with utility upgrades, such as adding a green roof or PV array, whilst also creating a scheme that safeguards the underlying Bauder waterproofing.
Why clients choose us
Surveyors, facilities managers and building owners choose us because of the way in which we do business, the way we treat every project individually, and how we work alongside customers, contractors, and all relevant stakeholders from project inception through to completion to deliver the best solution for a building.
We work on a one-to-one basis to ensure that the refurbishment roof specification we generate for you meets the needs of the building and project stakeholders and will confirm suitability of the solution to each roof area.
CCPI assessed product information
We have adopted the new Code for Construction Product Information (CCPI) across our roofing portfolio to have information assessed for accuracy and clarity to ensure specifiers can rely on the information when selecting a Bauder roofing solution.
Your project commands our attention
We assist you with the design of the detailing, writing the specification for the flat roof solution, and recommend suitable approved contractors to tender for the project. The service is without charge, and we work with you to ensure your roof specification meets all your needs.
Working with you
Our technical managers are based nationwide and play a vital role in the success of every project from initial investigative stage through to hand-over and sign-off of the Bauder installation. We work with you to understand:
Our service to you
We will support you in the design of a refurbishment roof to reinstate the integrity of the waterproofing, meet the needs of the building, allocated budget and all stakeholders. including:
Solving the challenge
Reviving a roof before water ingress occurs is far more cost effective than only working to rectify issues when a roof is reaching the end of its serviceable life and begins to fail. Our range of waterproofing membranes can be combined to deliver a solution that meets your expectations and matches the building's requirements including meeting current UK Building Regulations Part B for fire protection.
Re-establishing the integrity of your flat roof takes careful consideration, and we understand that you want to ensure your refurbished roof will be correctly specified to; meet the needs of the building, your budget, be reliable, trouble-free, and long lasting as well as come with a comprehensive guarantee.
Six steps is all it takes
Brief and consultation
You give us your remit either at your office or on-site. We will discuss the roofing project, your preferred system application, your budget and how the programme of work can be formulated.
Roof element proposal
Following a roof survey carried out by your Bauder Area Technical Manager, we can determine which roofing system and specific build up will be optimal for each individual roof area on your refurbishment project, given the construction type, level of access and required performance.
Specification and detail design
You will receive the Bauder specification package that answers your brief and meets the needs of the building. As a specialist designer for our solutions, we work with the Principal Designer to include relevant standard detail drawings and other technical calculations.
Contractor selection
The Bauder approved contractors best placed to deliver your new roof will competitively price and tender for your project. Our national network of contractors undergo a rigorous selection process and their installers are trained specifically in the application of our systems, so you are ensured an expert installation.
Installation of the roofing solution
Once the Bauder approved contractor has been appointed, a pre-contract meeting will make sure that the project delivery is well coordinated. The works are closely monitored by Bauder site technicians with regular inspections and live time reports to ensure the quality and waterproof integrity of the roof.
Sign off and guarantee
A full final inspection is completed by our site technician team before the guarantee is issued.
Bauder’s service doesn’t just stop once the roof installation has been completed, we provide industry-leading guarantees on our products that are installed by our national network of approved contractors.
Waterproofing systems and environmental solutions
There is a Bauder waterproofing solution for every flat roof situation, whether the membrane coverings are bituminous-based, plastic or resinous.
To ensure all flat roofs maximise the roof space to support the environment, it is important to consider how an extensive green roof or solar PV can be incorporated, and we can help with both.
Enhancing a roof by adding a PV array or green roof
Retrofitting photovoltaic panels brings all the benefits of low maintenance renewable energy generation to your project.
Adding a lightweight green roof enhances the benefits to the environment and increases the building's value.
