Roof Problem Areas - Liquid-Applied Roofing Materials

Since 1965, Belzona polymeric roofing materials and liquid roof coatings have been widely used for the repair and protection of all types of roof problem areas including joints, seams, glazing bars, skylights and flashings, which are especially prone to deterioration and damage leading to leaks. Our low-odour roof coatings have outstanding waterproofing and weatherproofing capabilities and will ensure your roof stays protected for as long as 20 years or more.

Roof waterproofing and protection from damage

Belzona manufactures a range of lightweight liquid-applied roof coatings such as Belzona 3111 (Flexible Membrane), which provide excellent waterproofing and weatherproofing properties, therefore ensuring long-term protection from leaks, damage and deterioration.

Our cold-curing roof coatings can be easily applied by brush or roller on almost any location including schools, hospitals and public buildings thanks to their low odour. The system incorporates reinforcement sheet to allow for easy control of the coating thickness during application and adapts to roof movement thanks to its outstanding elasticity.

Repair and protection of metal roofs and lead encapsulation

Belzona roofing materials are also widely used to repair and protect metal roofs, which are susceptible to damage and deterioration. Corrosion at the exposed cut ends of unprotected profiled steel sheets is unavoidable. Belzona liquid roof coatings are ideal for sealing the cut edges to prevent corrosion.

Due to its durability and strength, lead is a popular material for roof and chimney flashings; however, over time damage can occur. Weather deterioration, loose fixings and movement can result in roof leaks. Fast-curing epoxy materials such as Belzona 1212 can be used to seamlessly repair these areas minimising disruption to the building.

Encapsulation of entire lead roofs or replacement of missing lead using Belzona polymeric membranes is also a simple and effective method of preventing lead theft.

Joints, seams and emergency repair

Emergency repairs such as sealing of leaks, damaged expansion joints and seams can be instantly completed using Belzona 3121 (MR7), which will bond strongly to most roof substrates and will cure even if fully immersed in water, providing instant waterproofing.

Repair and sealing of corroded skylights and glazing bars can be completed using materials such as Belzona 3111 (Flexible Membrane), without any disruption to the facility.

Parapet walls and copings repair

Damaged and leaking parapet walls and copings can be easily repaired using Belzona 3121 (MR7), which can be applied even under adverse weather conditions. This microporous material is also used for other repairs including repointing of wall brick or mortar and sealing and repair of cracks in masonry walls.
