Flat Roof Paints

Flat roofs can be demanding for roof coatings due to the potential standing water, the year-round temperature changes and UV degradation. Due to these constant exposures to water and UV rays, it is vital that your flat roof is properly maintained with durable paints and coatings. At Rawlins Paints, we stock a range of tough, high-quality pitched and flat roof paints and coatings that have been specifically designed for flat roofs. Whether you are looking for products to provide essential maintenance to your flat or pitched roof or you need a high-performance coating for a new roof, we cover all these bases. 

If you are ever in doubt about whether a product is for flat roofs or pitched roofs, please check the product description, data-sheet or contact our Technical Team for advice on which roof paint will be best for your project.

Flat Roof Paints


When applied correctly, our high-performance flat roof paints, coatings and maintenance products can provide up to 25 years of protection. Our waterproofing membrane, coloured and clear coatings are suitable for a range of roofing materials, including felt, concrete, timber, asphalt and more. Our range of flat roof paints do not involve any hot works and are thus cold applied. This makes them safer in their use for both the user as well as the building. Most products are easily applied by brush, roller or spray, yet they provide optimal protection for your flat roofing – even when applied in low temperatures (product dependent).



Flat Roof Repair Paints


In the cases where repairs are needed, Rawlins Paints stock a range of flat roof repair paint. These are paints and coatings that are ideal to stop leaks and other weak points in the roof’s surface.

Even if you are dealing with an urgent repair that must be done in wet weather, there are solutions for this! Mathys have created a great coating that waterproofs instantly. Mathys Fillcoat provides a smooth liquid finish on not just roofs, but also for gutters, chimney stacks and pipes. It will seal small leaks quickly and easily, in all weather conditions.

Guarantees, Warranties and Life Expectancies for Large Roofing Projects


Our roof coating systems are designed to waterproof, protect and decorate almost all types of roofing materials. Roof coatings are often the most cost effective way to renovate a roof by allowing the user to extend the life expectancy without the need of a specialist contractor.

However, often larger roofing projects require some form of ‘guarantee’ for the client and/or building owner to provide peace of mind that the coating system applied to the roof will protect/waterproof the roof for an agreed period of time.

We offer systems that can be used year round to provide upto 5, 10, 15 and 25 years protection when applied by an approved contractor to flat, metal, pitched, felt, asbestos, corrugated roofs and more. Cold applied, seamless systems mean no need for heat or naked flames providing tough, elastomeric, waterproofing coatings that withstand thermal/structural movement.

We will visit your site and carry out a full inspection, write a tailored specification to meet your requirements and offer an approved contractor for the application. We will never offer a contractor that we have not trained and approved, all our contractors have successfully completed specific product training on the systems they apply and are monitored regularly to ensure the highest standard of quality is achieved.

By using one of our nationwide approved contractors for our products you enable yourself to take advantage of our guarantees, life expectancies and warranties. This means that if we say our system is going to last a certain amount of time, or perform in a certain way and it doesn’t, you’re covered.

If you’re a contractor and would like to become an approved installer of our systems please contact us on 0113 245 5450
