There are two different categories of metal roofs:
- Low-slope applications
- Steep-slope applications.
There is only one type of metal roof system used in low-slope applications — structural metal panels. Structural metal panel roof systems can be used for low slope roofs because of their water barrier characteristics. Structural metal panel roof systems can also be used for steep slope roof assemblies.
Most structural metal panel roof systems are designed to resist the passage of water at the joints. However, condensation should be expected to develop on the undersides of metal roof panels. Careful consideration should be paid to vapor retarder, insulation and ventilation issues.
Three general types of metal roof systems used for steep-slope roofing applications:
- Structural metal panel
- Metal shingle panels
Generally, architectural metal panel roof systems are water-shedding and are intended for use on steep slope roofs. Because architectural metal panel roof systems typically are designed to be used on steep slopes, the seams typically are not watertight. Most structural metal panel roof systems are designed to resist the passage of water at the joints.
Metal shingles and shingle panels are available in numerous varieties. Most of the metal shingles are press-formed during the manufacturing process to provide a variety of shapes. These products can take the shape of individual or multiple asphalt, tile, slate or wood shingle configurations.
There are many categories of metal panels: standing seam, batten, flat, Bermuda and shingled. Each provides a unique look for any roof.
Benefits of a Metal Roof
- Durability: Proven performance expectation of 50+ years
- Customization: Wide selection of styles, patterns and designs
- Protection: Interlocking panels for maximum wind resistance
- Safety: Metal Roof can be more fire resistance than other solutions
- Reduce energy costs: Light colored solutions reflect UV rays keeping your building cooler
- Light-weight: Help preserve structural integrity and life
