Commercial Roofing FAQs

Get answers to frequently asked questions about commercial roofing and connect with qualified commercial roofing contractors in USA.

Why do I need a roof curb for my HVAC unit?

Installing an HVAC unit on a roof curb is essential for:
  • Proper Drainage: The curb elevates the unit above the roof surface, allowing water to drain away from the unit, preventing corrosion and potential damage.
  • Waterproofing: The curb provides a solid base for flashing, ensuring a watertight seal around the unit's penetration point.
  • Airflow: A properly designed curb allows for adequate airflow around the HVAC unit, improving its efficiency and preventing overheating.
  • Maintenance Access: The curb provides a stable and accessible platform for maintenance personnel to service the HVAC unit.

What is a roof curb?

A roof curb is a raised framework, typically made from wood or metal, built on a flat roof to provide a raised platform for mounting rooftop equipment, such as:
  • HVAC units
  • Skylights
  • Exhaust fans
  • Solar panels
Roof curbs elevate the equipment above the roof surface, providing proper drainage, preventing ponding water, and ensuring a watertight seal around the penetration. They are crucial for the longevity and performance of the roof and the installed equipment.

What are the different types of commercial roofing systems?

There are several types of commercial roofing systems commonly used, each with its own advantages and disadvantages:
  • Built-Up Roofing (BUR): A traditional, multi-layered system consisting of alternating layers of asphalt and reinforcing fabric. It's known for its durability, waterproofing capabilities, and affordability.
  • Modified Bitumen Roofing: A single-ply system that uses asphalt-based sheets modified with polymers for enhanced flexibility, durability, and weather resistance. It's a versatile and cost-effective option for various commercial buildings.
  • Single-Ply Membrane Roofing: A modern system using a single layer of waterproof membrane, typically made from EPDM (ethylene propylene diene monomer) rubber, TPO (thermoplastic polyolefin), or PVC (polyvinyl chloride). These membranes offer excellent waterproofing, energy efficiency, and ease of installation.
  • Metal Roofing: Known for its longevity, durability, and fire resistance, metal roofing is a popular choice for commercial buildings. Available in various styles, including standing seam, corrugated, and metal shingles.
  • Spray Polyurethane Foam (SPF) Roofing: A spray-applied roofing system that forms a seamless, monolithic membrane, providing exceptional insulation, waterproofing, and energy efficiency.
  • Green Roofing: A system that involves covering the roof with vegetation, soil, and drainage layers. Offers environmental benefits, including reduced stormwater runoff, improved air quality, and energy efficiency.
Choosing the best roofing system depends on various factors, including your budget, building structure, climate, and specific needs. A qualified commercial roofing contractor can assess your roof and recommend the most suitable option.

How do I prevent ponding water on my commercial roof?

Ponding water, the accumulation of water on a flat roof, can lead to:
  • Leaks
  • Structural damage
  • Premature roof deterioration
To prevent it:
  • Proper Design and Installation: Ensure your roof has a sufficient slope for proper drainage during the design and construction phase.
  • Regular Inspections and Maintenance: Inspect the roof regularly for clogged drains or debris buildup.
  • Repair Sagging Areas: Address any sagging or low spots on the roof, as they can trap water.
  • Tapered Insulation: Consider installing a tapered insulation system to create a gradual slope toward the drains.
