Whether you're running gas lines, HVAC piping, or electrical conduit across a rooftop, using the right pipe supports is essential for protecting the roof membrane, maintaining system stability, and ensuring long-term performance. But before selecting a solution, it’s important to answer a few key questions:
- What are roofing pipe supports?
- Why are they important to roof integrity and longevity?
- How do you choose the right type for your project?
At Big Rock Supply, we provide contractors with top-quality roofing and construction equipment—including trusted pipe support systems from industry-leading brands. In this guide, you'll learn the fundamentals of pipe supports, understand key selection criteria, and explore products built to perform in real-world roofing environments.
What Are Roofing Pipe Supports and Why Do They Matter?
Roofing pipe supports are devices used to elevate and secure various rooftop utilities, including:
- Mechanical piping
- Electrical conduit
- Gas lines
- HVAC refrigerant lines
- Solar mounting components
These supports serve several key functions:
- Protect the roof membrane by preventing direct pipe contact, which can lead to abrasion or punctures.
- Distribute weight evenly to avoid concentrated pressure points.
- Provide stability against wind uplift, thermal movement, and vibration.
- Ensure proper drainage by keeping piping above potential water pooling areas.
Pipe supports are especially crucial on flat or low-slope commercial and industrial roofs, where a large volume of rooftop equipment are present.
Featured Brands in Action
- Miro Industries: Industry leader in non-penetrating and adjustable pipe supports for mechanical systems on flat commercial roofs.
- C-Port (by Clearline): Known for being eco-friendly. 100% recycled rubber bases that are chemical- and weather-resistant.
- Greenlink Engineering: Their KnuckleHead series offers high-performance, corrosion-resistant support systems for conduit, piping, and equipment.
Choosing the Right Pipe Support: Key Considerations
With many support systems on the market, how do you choose the right one? Here are some key factors to consider when choosing the right pipe support:
1. Weight Load Capacity
- Consider the combined weight of pipes, insulation, and contents (e.g., water, refrigerant).
- Brands like OMG Roofing Products offer pipe supports that are engineered for heavy-duty, high-performance commercial roofs.
2. Pipe Size & Utility Type
- Match the pipe diameter and function to the support’s cradle or strut system.
- PipeProp offers simple yet flexible options compatible with a range of pipe sizes—ideal for lighter loads in residential or light commercial work.
3. Roof Type: Flat vs. Pitched
- Flat roofs are more forgiving and typically use non-penetrating bases like those from C-Port, RoofTop Blocks, or Miro Industries.
- Pitched roofs may require custom anchoring or engineered solutions, especially where sliding is a concern.
4. Material & Durability
- Common materials include rubber (recycled or molded), plastic, or high-performance polymers.
- For extreme conditions, Greenlink’s KnuckleHead system shines with its UV, corrosion, and temperature resistance.
- RoofTop Blocks also offers UV-resistant supports made from recycled rubber or foam—lightweight, durable, and modular.
5. Environmental & Weather Conditions
- Exposure to UV, wind, snow, and chemicals all factor in.
- C-Port supports are especially popular for harsh weather and chemical exposure due to their rugged rubber base.
- Miro Industries and OMG’s OlyFlow systems are built with long-term weather resistance and roof system compatibility in mind.
Penetrating vs. Non-Penetrating Pipe Supports: Pros and Cons
Understanding the difference between penetrating and non-penetrating supports is key to roof performance and integrity.
Non-Penetrating Supports
These sit directly on the roof surface without requiring fasteners or mechanical attachments.
Pros:
- Preserve roof membrane and waterproofing
- Easier and faster to install
- Ideal for most flat or low-slope commercial roofs
Cons:
- Not suitable for steep slopes
- May require additional weight/stabilization in high-wind areas
Top Non-Penetrating Brands:
Penetrating Supports
These are mechanically attached to the roof deck, often through curbs or sealed fasteners.
Pros:
- Provides rigid, permanent support in dynamic environments (e.g., seismic zones, steep roofs)
- Useful for projects requiring exact pipe alignment or higher structural load handling
Cons:
- Requires flashing and sealing to maintain watertightness
- Increases labor and materials cost
When to Consider:
- On sloped roofs or when mandated by structural engineers
- For code compliance or high-movement systems (e.g., large HVAC units)
