The integral locking seam is held in place by concealed metal clips, and is installed over a waterproof solid substrate. The absence of exposed fasteners and the weather-tight side lap, allow for applications on roof pitches as low as a 3:12.
High-quality, pre-painted metal roofs afford an attractive life cycle cost in addition to many other advantages.They will not crack, shrink, or erode, making them a long lasting alternative to many conventional roofing materials.
Consider the radiant heat reflectance of light colored metal in warm climates, resulting in cooling cost savings. Also, pre-painted metal readily sheds snow and ice, a distinct advantage in high snow areas.
Pre-painted metal can usually be installed over existing roofs. Disposal of old conventional materials can be difficult and costly. The use of pre-painted metal can often solve this problem
Consider the fact that metal doesn't burn! Non-combustibility should offer protection from external hazards such as windblown sparks or lightning when properly grounded.
Properly installed pre-painted metal roofs should not need periodic repair or replacement due to wind damage or storms. Properly installed pre-painted metal roofs do not absorb water or moisture. Water can damage most other roofing materials by rotting or cracking during a freeze-thaw cycle.
