What is: Inverted Roof

An inverted roof is a type of flat roof construction where the insulation layer is placed on top of the waterproofing layer. This design helps to protect the waterproofing membrane from temperature fluctuations, UV exposure, and mechanical damage, extending the lifespan of the roof.

Benefits of Inverted Roof

One of the main benefits of an inverted roof is its ability to provide better thermal performance compared to traditional flat roofs. By placing the insulation on top, the roof structure is protected from temperature variations, reducing the risk of condensation and heat loss.

Installation Process

The installation process of an inverted roof involves laying the waterproofing membrane first, followed by the insulation layer. The insulation boards are then covered with a protective layer, such as ballast or pavers, to provide additional protection and weight to the roof system.

Maintenance and Repairs

Regular maintenance of an inverted roof is essential to ensure its long-term performance. Inspections should be carried out to check for any damage to the waterproofing membrane or insulation layer, and repairs should be made promptly to prevent water infiltration.

Cost Considerations

While the initial cost of installing an inverted roof may be higher than traditional flat roofs, the long-term savings in energy costs and maintenance expenses make it a cost-effective option for many homeowners. Additionally, the extended lifespan of the roof adds value to the property.
