PermaRoof Garages Product Range

EPDM Garage Roofing
EPDM membranes offer some of the highest performance levels in the industry, offering a service life expectancy of over 50 years, ideal for garage conversions. We developed a range of garage roofing kits including RubberCover EPDM membrane to simplify both ordering and installation.

Liquid Waterproofing
Liquid roof coatings are ideal for complex garage roofing projects and cover a range of substrates typical to traditional garage roofs, such as concrete. Applied in a single coat with a self-levelling compound, liquid waterproofing systems can seal and protect a concrete flat garage roof quickly.


Green Garage Roofing
A garage conversion offers an opportunity for many to create an eco-friendly green roof to attract wildlife and birds. Aesthetically beautiful, green roof projects are increasingly popular and not as difficult to create as you may think. We offer full support from start to finish, with expert advice and a range of resources to guide you through all your eco roofing projects.

Modular Garages
Thinking about building a garage from scratch? Modular garages are fast and easy to erect and are manufactured from high quality galvanised steel for a long term approach. Off the shelf, standard buildings or full custom design service available for a tailored modular garage to suit your exact requirements.

Why re-roof a garage conversion?
Traditional garage roofing was historically suitable for housing vehicles, tools and for other household storage. However, now garages are increasingly changing use for a growing number of homeowners across the UK. Many are now realising the benefits of creating additional useful space at home for a wider range of uses:
Garage conversions are now housing expensive equipment, electronics and furnishings, which require a reliable, watertight roof to protect them. Most traditional garage roof materials simply aren’t enough for the modern conversion project and will need to be upgraded to deliver the waterproofing needed.
Attached flat roof garages are increasingly becoming part of the house in extension projects too. Many homeowners are preferring to extend rather than move house and an attached garage is often fast and easy to convert.

EPDM is perfectly suitable for installation onto a concrete garage roof. Primer and bonding adhesive will need to be used in conjunction with a high performance membrane for the best results.

EPDM membrane is a high performance option that offers longevity and reliability with a 50-year service life expectancy. Fast and easy to install, and available in kit form, EPDM can tick many boxes for both homeowners and trade roofing professionals.
Yes. Sufficient adhesive, sealant, membrane, trim and fixings are all included in your garage roof kit. Simply enter the roof sizes, and we’ll calculate the right quantities for you.
We stock standard sized, off-the-shelf single and double garage roof kits. We also offer a custom, enter-your-own-size option. For the custom kit, you will need to enter the width and length of the garage in metres.
Measuring tips
- Measure on the ground outside the building
- Measure twice
- Ask someone else to check the measurements
- Add 300mm to both length and width to allow for overhang
The ideal length of overhang is around 150mm. We allow an additional 300mm of EPDM in our standard garage roof kits to ensure an even overhang on all sides. Please add 300mm to both width and length measurements when ordering enter-your-own-size kits.
