What is Liquid Rubber Roofing?
Liquid rubber roofing is an acceptable term used for these types of systems, yet they are essentially liquid polyurethane-based (PU). Not a brand new concept, liquid PU has been taken a step further by PermaRoof in the introduction of our latest liquid rubber roof systems.
We have developed long-term solutions to waterproofing for domestic, industrial and commercial properties. They can also deliver wider benefits over a range of applications from roofing to anti-slip surfacing and more.
Manufactured with a polyurethane base, our synthetic liquid rubber solution covers even the most complex areas of the roof and is effective over almost any substrate. The system uses a Permaband reinforcing matting for integrity and is fast, safe and straightforward to apply.
Why choose a liquid rubber (PU) system?
Applying Liquid Rubber Roofing
Installing a PermaRoof liquid roof is super-smooth and fast. It cures quickly and is effective immediately, which makes it ideal for fast repairs or roofing replacement.
Our systems need few tools for application. Safely and quickly apply a single coat of liquid rubber using a foam roller. Brushes or small rollers can be used for detailed areas. The product contains a self-levelling compound so does not have to be overworked. (It is suitable for pitched roofing with the addition of a solution to remove the self-levelling properties).
The benefits of installing roof trim
The edges of any flat roof installation can benefit from roof trim, which ensure that the project is kept fully and reliably watertight.
Installing edge and gutter trims also create a professional-looking, neat finish around any exposed edges. This is true of both sheet membrane and liquid rubber roofing. Trim is installed once the surface is fully cured and this is the perfect way to complete the project.
A note about anti-slip mediums
When creating an anti-slip surface, such as a car parking zone or to make safe slippery garden steps and paths, use a recommended medium for the best results. This can be mixed with the liquid rubber solution or for a different spread and finish, hand-cast across the still-wet surface.
Preparation tips
Choose a dry day for installation with no rain expected
Carry out any necessary roof repairs before application
Use good quality rollers and keep a spare sleeve handy
Mask off facias and soffits to protect from drips or spots
Remove all loose debris, dirt and dust from the roofing surface
If you’re covering an existing system, make sure any ill-fitting or loose parts are completely removed
Remove any oil or grease from the roof surface before applying the liquid PU
Keep safety in mind while working at height
Wear suitable protective clothing

Liquid Rubber Roof FAQs
For many applications, a liquid coating can provide a more comprehensive solution, effectively sealing complex surfaces where membrane is difficult or impossible to install. This can include historically damp situations, such as basements, cellars or other structures with buried roofing.
Being cold applied, often in a single coat makes it safer and faster to apply than other types of waterproofing. As it can also be applied to a wider range of substrates and even cover some types of existing covering, it can sometimes offer a more flexible approach than membrane for homeowners tacking complex projects.
