What is Galvalume®

Galvalume® steel is the result of an ideal alloy of Aluminum and Zinc. It consists of Aluminum (55% in weight ratio but 80% in surface volume ratio), Zinc (43.4% in weight), and Silicone (1.6% in weight ratio) so it has both Aluminum-unique corrosion-resistance and heat resistance and Zinc-unique “Galvanic Behavior”.

 Re-Roofing

As Roser roofing tile is light, it does not impose a large load on the structure of the building. In addition, if the existing roof frame is in a good state, it can be easily and quickly re-roofed without tearing off the existing roofing material and, therefore, the disposal cost due to the removal of the existing roof can be saved

Fire Resistant

Since Roser stone coated steel roof is a roofing material made of Galvalume steel and stone granules, it has a strong fire resistance and can minimize damage from fire.

(Complies to UL 2218, Japan Non-Combustible Test, KSF Non-Combustible Test)

Rain(Noise) Resistent

 Snow Resistant

It should be noted that the snow on the upper layer may fall off from the roof as the snow on the roof begins to melt down. In areas where it is recommended to use a snow stopper, a snow stopper must be installed on the Roser roof tiles.

 Wind Resistant

Roser roofing system is a roof system designed to be strong against wind with a unique installation method despite the weight of about 1/6 of other conventional roofing materials. Compared to most other roofs having a vertical fixing, each Roser tile is fixed horizontally and overlapped each other (interlocking construction) which are designed to be very resistant to tornadoes and strong winds

 Excellent Ventilation

In wooden house construction, ventilation plays an important role in protecting the wood from moisture. Unlike asphalt shingle, Roser roofing system uses a non-adhesive installation method and has a space between the roof tile and wood deck which provides excellent ventilation

 Enhanced Installation

Roser ROWOOD035 roof tile is suitable for sites requiring stronger bonding. It can be installed easily when using professional tools such as electric drills because of the higher level of the joint surface of the tiles. The screw-type metal tile can be fixed more strongly than general tile, ensuring higher durability against wind and external pressure.
