PermaKit – Flat Roof Calculator & Quote Tool

PermaKit was created by PermaRoof UK in response to a roofing industry demand for a tool to simplify quantifying and ordering rubber roof systems. This free, online EPDM roof kit calculator is a key part of a wider support offering at PermaGroup.

Developed initially to simplify the quotation process for EPDM trade roofers, the PermaKit Builder has risen in popularity and has today become an invaluable tool for DIY projects.

Planning the materials list for a roofing project can prove challenging, even for trade professionals. With meterage calculations, coverage rates, perimeters and detailing to consider, it can be a time-consuming process. However, using a kit builder isn’t just about saving time for trade and DIY roofing projects, it can bring a wider range of benefits to projects of all sizes:

Streamlined project planning
Accelerated quotation
Minimised wastage
All materials calculated accurately
Everything included

Developed for convenience, the PermaKit builder app works fast and requires few details to deliver an accurate, intuitive materials list:

Accurate measurements – the app calculates precise quantities and relies on accurate measurements for success

Project details – for a full and complete flat roof kit list, add project details to allow for the calculation of roof trim, flashing and primer and other necessary accessories.

Some examples are:

the location of adjoining walls
if there are parapet walls or upstands
the type and location of extrusions (e.g. flue pipes or skylights)

The measurements and project details are added to the app in four clear steps in a user-friendly interface, which can take just minutes.

Once completed, the app returns a complete kit list, giving you the option to check it over and adjust if you see fit. This kit list will include EPDM membrane, adhesive and everything needed to complete the project you outlined – in the right quantities.

After the list is finalised, there is the option to print, share or save it. If you’re ready for a quotation, there is the option to submit the quote to the sales team for the best price for your complete rubber roof waterproofing kit.

Simplify and streamline materials planning

From the substrate-up, PermaRoof can supply everything needed for the project in an EPDM kit tailored to exact specifications. We also provide standard, off-the-shelf kits developed for trade and DIY home roofing projects, such as shed waterproofing, extension and garage roof replacements in our online store here.

PermaKit has been evolving alongside PermaRoof UK for many years, now standing independently as a valuable part of the PermaGroup brand.

The introduction of our innovative roofing calculator was initially to support our trade roofing clients in the acceleration and simplification of their quotation process. It quickly became an invaluable part of the toolbox – transforming the way many of them quantified and ordered materials.

Today, PermaKit is a popular tool for the wider DIY community, providing the means to automate this crucial part of any flat roof waterproofing project.
