Advantages of Low Slope Metal Roofs:
- Years of low cost and low maintenance
- Allow water better runoff as compared to flat roof
- Long service life
- Recyclable
- Less weight on overall structure
- Low life cycle cost
- Essentially you can have an additional floor of space as compared to when a steep slope roof is utilized
Considerations for Low Slope Metal Roofs:
- Care must be taken to ensure all flashings are fabricated properly and installed to allow water flow
- Attention must be given to ensure that debris is not allowed to build up that would hinder water flow
- Sealants applied properly and at all critical locations
- Complexity with many roof penetrations
Common Applications:
- Warehouses
- Schools
- Office buildings
- Industrial
- Shopping centers
- Residences
- Metal building community
Low Slope Retrofit Open Framing:
- No removal/disposal of old roof system
- Minimal weight added to existing roof structure
- New insulation/waterproofing is able to be installed over existing flat roof
- Existing structure is never open to the elements during renovation
