Underlay is laid under your roof tile battens during installation by the Reseller. It is rolled out in sections parallel to the eaves with an overlap between each layer. The battens are then used to secure the underlay to the roof rafters before laying the roof tiles.
Monier recommends the use of underlay in all situations. Underlay is required in all situations when a spreader discharges water over the roof.
Monier has a proud history in the New Zealand building industry, from the original terracotta tile to the extensive range available today, Monier tiles have long been a trusted roofing solution.Product Enquiries
