Commercial Roofing FAQs: What Businesses Should Know

Most commercial roofs fit into two categories: flat or low-slope roofs and steep-slope roofs. We provide both.

Flat and Low-Slope Roofing Options (TPO, EPDM, Modified Bitumen)

Knickerbocker Roofing provides the following flat and low-slope options: 

• Single-ply
• Modified bitumen
• Built-up roofing
• Metal roofs
• Liquid membrane options

The right choice depends on the foot traffic, equipment installation, and budget of your building.

Steep-Slope Materials for Institutional or Specialty Projects

We also offer a wide range of steep-slope roofing materials that provide aesthetic appeal or long-lasting functionality with budget-friendly maintenance. Talk to our experts about: 

• Clay tile
• Shingle
• Slate
• Wood shake

How to Choose the Right System for Your Building Type

The right roofing system depends on the architectural style of your building. Most commercial properties have flat and low-slope roofing installations, while historic or specialty buildings and institutional campuses are more likely to have steep-slope roofs.
