UNIQUE BENEFITS FOR FELT SUBSTRATE ROOFS
Jointed Roof to Jointless Roof
One of the remarkable benefits of coating a felt roof with polyurethane is its capability to provide a seamless and consistent finish that eliminates seams and joints – commonly the root cause of leaks.
Typically, felt roofs comprise several layers of felt that are bonded with bitumen or tar. As time goes by, these layers can become brittle, crack, and joints and overlaps may fail.
By applying a polyurethane coating to the felt roof, the surface can be effectively sealed, creating a seamless, jointless, and uniform membrane that no longer relies on the felt for protection. Therefore, there is generally no need to remove the felt before applying the coating on most roofs.
Additional Benefits

Direct Application Over Old Felt – The coating can be applied directly over the existing felt surface, creating a seamless and waterproof barrier that protects against weathering and damage. However, it’s important to evaluate the condition of the existing felt before applying the coating, as sometimes the felt may need to be removed if it has completely detached from the roof.

Improved Appearance – Polyurethane coatings can be applied in various colours and finishes, allowing for greater flexibility in achieving the desired aesthetic appearance for the roof. The coating can also provide a durable and long-lasting barrier that is highly resistant to environmental damage, including water, chemicals, and UV radiation.

Cost Effective – As it can be easily applied over the existing felt, making it a cost-effective option for building owners and managers. Reducing the need for regular maintenance and repairs can provide long-term savings and peace of mind. Overall, a polyurethane coating offers an effective way to safeguard a felt roof from potential damage while also saving on maintenance costs, though it’s crucial to assess the state of the felt before applying the coating.

Temperature Regulation – By adding an extra layer of insulation, the coating can also help to regulate temperature and improve the overall comfort of the building’s occupants.

Application – Joint Only or Full Reinforcement
Improving the waterproofing of old and weathered felt roofs, with the application options of either joint only reinforcement with taped joints or full reinforcement with chop strand glass fibre matting.
