Just like roofs of old times, modern roofs offer protection from the elements, but in addition they also provide a variety of functions for the house. When it comes to caring for one’s roof, it is more than just coverage, as there are many other elements to consider.
A new standard in roofing
The energy efficient production process and long product life cycle of concrete tiles mean that they have one of the best environmental footprints of all roofing materials. Coupled with their industry leading, 30-year roof tile guarantee, BMI has set the standard in roofing. Contrary to popular belief, a concrete tile roof is quite cost effective compared to other roof coverings, which becomes apparent when one looks at a comparative quote for the complete installation cost of a roof.
Understanding indoor comfort
The roof affects the indoor climate of one’s house or building. Ultraviolet (UV) rays penetrate through the roof surface, making the interior of the house hot in the summer, and escape through the roof in the cooler months, leading to an increased consumption of electricity for heating and cooling equipment.
The BMI Coverland Radenshield range reflects 97% of UV rays, while also keeping in the warmth during the winter. It reduces the indoor temperature by up to 10°C in the summer. It is recommended as a replacement for standard under-tile membranes, and is manufactured for residential and industrial use.
Maintenance-free, leak-proof ridges
One of the most common maintenance problems with roofs is leaks. Roofs commonly leak due to flashing details that weren’t fastened properly during the installation, or underperforming material. In South Africa, traditionally the roof ridge and hip tiles are fixed with mortar that can crack, causing wind-driven rain to enter the roof.
Maintenance-free ridges are achieved using BMI’s waterproof yet breathable Figaroll Plus rolls, which are mechanically fixed to the roof ridge and hip lines, replacing mortar that cracks and leaks. BMI Coverland EasyFlash and Wakaflex abutment rolls are a high-performing, lead-free alternative to traditional waterproofing for walls and roof junctions.
In addition, BMI’s Coverland underlays offer resistance against wind penetration. Nails and storm clips are recommended to secure roof tiles in all parts of South Africa, so make sure they are installed as per legislation.
Quality and durability of materials
High-quality products are essential for the durability of any roof. Excellent performance and ease of use on the roof are vital for the success of BMI’s roofing systems, which is why all BMI Coverland roofing materials are tested on an ongoing basis at the Group Testing Facility in Germany to ensure that they conform to the relevant local and international quality standards.
Whatever the roofing needs, BMI Coverland specialises in the manufacturing of a wide variety of concrete tile profiles with accompanying ridge/hip fittings, perfectly suited for creating a distinctive look.
