Investing in professional roof sealing offers significant advantages for your home or business:
A well-sealed roof is your first defence against water intrusion, protecting your property from leaks and the potential for water damage.
Sealing your roof can significantly reduce heating and cooling costs by preventing air leaks, keeping your indoor environment more comfortable with less energy usage.
By protecting your roof from the elements, sealing extends its lifespan, delaying the need for repairs or replacement and saving you money over time.
A sealed roof offers added resistance against wind, rain, UV radiation, and other environmental factors, keeping your property secure in all seasons.
Roof sealing helps prevent the growth of mold, algae, and fungi, which can deteriorate roofing materials and lead to expensive repairs. A properly sealed roof maintains a cleaner appearance and promotes a healthier environment around your home.
A well-sealed roof can also contribute to a quieter indoor environment by providing an additional layer of insulation against external noise. Whether it’s traffic, rain, or wind, sealing your roof can help keep those sounds at bay, making your home more peaceful.

Frequently Asked Questions About Roof Sealing
What is roof sealing?
Roof sealing involves applying a suitable liquid coating or waterproofing system to a compatible roof surface. Once cured, the system creates a protective layer designed to help keep the roof weather-resistant and reduce the risk of water penetration.
What types of roofs can be sealed?
Roof sealing products can be suitable for a range of roof surfaces, but not every coating is suitable for every roof. The existing roof material, condition and construction need to be assessed before the appropriate system is selected.
Can roof sealing stop a leaking roof?
Roof sealing can help resolve certain leaks where the existing roof is suitable for a liquid-applied waterproofing system. However, damaged areas, failed detailing or underlying roofing problems may need to be repaired before a coating is applied.
Can an old roof be sealed instead of replaced?
In some cases, an existing roof can be refurbished using an appropriate waterproofing or overlay system rather than completely replaced. This depends on the condition of the roof and whether the existing structure and surface are suitable for treatment.
Does the roof need to be cleaned before sealing?
Yes. Proper preparation is an important part of roof sealing. The surface generally needs to be clean and suitably prepared so that the chosen coating can adhere correctly. Any defects that could affect the finished system should also be addressed before application.
Can roof sealing extend the life of a roof?
A suitable waterproofing system can help protect an existing roof covering from further weather exposure and may extend its useful service life. The result will depend on the condition of the existing roof, preparation, product used and quality of installation.
Is roof sealing the same as roof repair?
No. Roof sealing is a waterproofing or protective treatment, while roof repairs address specific defects such as damaged coverings, failed joints or deteriorated details. In many cases, repairs may be required before a sealing system can be applied.
How long does roof sealing last?
The lifespan of a roof sealing system varies depending on the product, roof surface, installation, exposure to weather and ongoing maintenance. We can recommend a suitable system after inspecting the roof and assessing its condition.
How much does roof sealing cost?
The cost depends on the size and condition of the roof, the surface being treated, preparation and repair work required, access and the waterproofing system selected. A property survey allows us to assess the roof and provide an accurate quotation.
