Low Slope Metal Roofing Applications

March 26, 2018

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
