Designing the Right Single Ply Roofing System

Suitable Substrates For Monarplan Single Ply Roofing Systems

The load bearing structure must comply with all associated national standards and regulations, ensuring that the load bearing capacity is sufficient for any additional loads imposed upon the construction. It is important to consider the possibility of future deflection of the construction when designing roof drainage.

Substrates must be strong enough to permit the penetration of fixings whilst maintaining suitable pull out strength. It is recommended that pull out tests are conducted prior to the application of the Monarplan single ply roof system.

Acceptable substrates

The Monarplan single ply roofing can be installed on new construction or over existing roofs, when the existing roofing assembly is dry or the wet areas have been removed and replaced; or when the existing roof is completely removed to the deck. The roofing contractor has the final responsibility of acceptance of the surface to receive the roofing system.

The following structural substrates are acceptable for the Monarplan PVC single ply systems:

Profiled Metal  Plywood or OSB  Timber Boarding

Structural Concrete  Other Substrates
