Commercial roofing is a critical aspect of any business owner’s property in New Orleans.
The unique challenges posed by the city’s high heat, drainage issues, and local building codes make it essential to choose the right roofing materials and partner with experienced professionals.
In this article, we’ll explore the key considerations for commercial roofing in New Orleans and help you make informed decisions to protect your investment.

Choosing the Best Roofing Materials for High Heat in New Orleans
New Orleans is known for its sweltering summers, with temperatures often soaring into the 90s.
This extreme heat can take a toll on commercial roofing materials, causing them to deteriorate more quickly than in milder climates.
When selecting roofing materials for your New Orleans business, consider options that are designed to withstand high temperatures, such as:
- Reflective coatings: Applying a reflective coating to your roof can help reduce the amount of heat absorbed by the building, lowering cooling costs and extending the life of your roof.
- Single-ply membranes: These lightweight, durable materials, such as TPO and PVC, are designed to resist UV damage and maintain their integrity in high heat.
- Metal roofing: While metal roofs can get hot in direct sunlight, they are highly reflective and can be coated with heat-resistant finishes to improve their performance in high temperatures.
| Material | Benefits | Drawbacks |
|---|---|---|
| Reflective coatings | Reduces heat absorption, extends roof life | May require reapplication over time |
| Single-ply membranes | Lightweight, durable, UV-resistant | Can be punctured by sharp objects |
| Metal roofing | Highly reflective, heat-resistant finishes available | Can be noisy during rain or hail |
Ensuring Proper Drainage for Flat Roofs in New Orleans
Flat roofs are common on commercial buildings in New Orleans, but they can be prone to drainage issues if not properly designed and maintained.
Standing water on a flat roof can lead to leaks, damage, and even structural issues over time.
To ensure proper drainage, consider the following:
- Tapered insulation: Installing tapered insulation on your flat roof can help create a slope that encourages water to flow towards drainage points.
- Regular maintenance: Keeping your roof free of debris and regularly inspecting drainage points can help prevent clogs and ensure that water is able to flow freely off the roof.
- Overflow scuppers: Installing overflow scuppers provides an additional drainage point for heavy rain events, reducing the risk of water ponding on the roof.
Complying with New Orleans Commercial Roofing Codes
New Orleans has specific building codes and regulations that apply to commercial roofing projects.
Failing to comply with these codes can result in fines, project delays, and even legal issues.
Some key considerations include:
- Wind uplift requirements: New Orleans is prone to high winds during hurricanes and tropical storms, so commercial roofs must be designed to withstand these forces.
- Energy efficiency standards: The city has adopted energy efficiency standards for commercial buildings, which may impact the type of roofing materials and insulation required.
- Permits and inspections: Most commercial roofing projects in New Orleans require permits and inspections to ensure compliance with local codes.
| Code Requirement | Description | Importance |
|---|---|---|
| Wind uplift | Roof must withstand high winds | Protects building and occupants during storms |
| Energy efficiency | Meet city standards for efficiency | Reduces energy costs and environmental impact |
| Permits and inspections | Obtain necessary permits and pass inspections | Ensures compliance and avoids fines or legal issues |
Durable Roofing Solutions for New Orleans Businesses
Given the unique challenges of the New Orleans climate, it’s important to choose commercial roofing solutions that are built to last.
Some of the most durable options include:
- Built-up roofing (BUR): This traditional roofing system consists of multiple layers of bitumen and reinforcing fabric, creating a thick, durable barrier against the elements.
- Modified bitumen: Similar to BUR, modified bitumen roofing uses a more flexible asphalt compound for enhanced durability and resistance to temperature extremes.
- Spray polyurethane foam (SPF): This lightweight, seamless roofing material is sprayed directly onto the roof surface, creating a highly durable, insulating barrier that can withstand high winds and heavy rain.
Bluebell Cafe, a popular New Orleans restaurant, recently opted for an SPF roof when replacing their aging built-up roof. “We couldn’t afford to have leaks or damage disrupt our business,” says owner Mark Thompson. “The SPF roof has been a game-changer – it’s held up beautifully through several heavy storms, and our energy bills have gone down, too.”
Impact of New Orleans Weather on Commercial Roofing
New Orleans’ humid subtropical climate means that commercial roofs are subjected to a wide range of weather conditions throughout the year.
From intense summer heat and heavy rainfall to the risk of hurricanes and tropical storms, it’s crucial to choose roofing materials and systems that can withstand these challenges.
Some key weather considerations include:
- UV radiation: The intense sunlight in New Orleans can cause roofing materials to break down over time, making UV-resistant options like single-ply membranes or reflective coatings a smart choice.
- Heavy rainfall: With an average of 62 inches of rain per year, New Orleans roofs must be designed to efficiently shed water and prevent leaks. Regular maintenance and proper drainage are essential.
- High winds: Hurricane-force winds can cause severe damage to commercial roofs, making it important to choose materials and designs that are rated for high wind uplift resistance.
| Weather Factor | Potential Impact | Mitigation Strategies |
|---|---|---|
| UV radiation | Material breakdown, reduced lifespan | Choose UV-resistant materials, apply reflective coatings |
| Heavy rainfall | Leaks, water damage, structural issues | Ensure proper drainage, perform regular maintenance |
| High winds | Lifted or torn roofing, water infiltration | Select materials rated for high wind uplift, secure all components |
