Understanding Built-Up Roof Restoration in New Orleans
Built-up roofing, also known as BUR, is a common choice for flat or low-slope roofs on commercial and industrial properties in New Orleans.
These roofs are constructed with alternating layers of bitumen (asphalt) and reinforcing fabrics, creating a robust, waterproof membrane.
Over time, exposure to the elements, foot traffic, and other factors can cause built-up roofs to deteriorate, leading to leaks, cracks, and other issues.
Restoration focuses on repairing and revitalizing the existing roof, rather than completely tearing it off and replacing it.
The restoration process typically involves:
- Thorough cleaning and preparation of the roof surface
- Repair of any damaged or deteriorated areas
- Application of new bitumen and reinforcing layers
- Installation of reflective coatings or granules
By restoring a built-up roof, property owners can extend its lifespan by 10-15 years or more, depending on the specific conditions and materials used.
This not only saves money compared to a full replacement but also minimizes disruption to building operations.
Addressing Moisture Damage from High Humidity
One of the biggest challenges for built-up roofs in New Orleans is the high humidity levels throughout much of the year.
Constant exposure to moisture can lead to issues like:
1. Blistering and ridging of the bitumen layers
2. Accelerated deterioration of the reinforcing fabrics
3. Growth of algae, moss, and other organic matter
During the restoration process, contractors use specialized techniques and materials to mitigate and repair humidity-related damage.
| Moisture Issue | Restoration Solution | Preventative Measure |
|---|---|---|
| Blistering | Remove and replace damaged bitumen | Install vents to allow moisture to escape |
| Fabric deterioration | Apply new reinforcing layers | Use moisture-resistant fabrics |
| Organic growth | Thoroughly clean and treat roof surface | Apply fungicides and algaecides |
To prevent future moisture damage, restored roofs may also receive additional layers of waterproofing, as well as improved ventilation and drainage systems.
Assessing Storm Damage and Repairing After Hurricanes
New Orleans’ location makes it vulnerable to hurricanes and severe tropical storms, which can wreak havoc on built-up roofs.
High winds can tear off sections of the roof membrane, while flying debris can puncture and damage the surface.
After a major storm event, it’s crucial to have a professional inspect the roof for signs of damage, such as:
- Loose or missing flashing
- Cracks or splits in the bitumen layers
- Saturated or compressed insulation
- Damaged or displaced rooftop equipment
Once the extent of the damage is assessed, contractors can develop a targeted restoration plan to repair and reinforce the affected areas.
This may involve patching or replacing damaged sections, installing new flashing and sealants, and applying additional protective coatings to enhance the roof’s resistance to future storms.
| Damage Type | Repair Strategy | Reinforcement Option |
|---|---|---|
| Torn membrane | Remove and replace damaged section | Install high-wind rated materials |
| Punctures | Patch with compatible sealants | Add extra layers of reinforcing fabric |
| Flashing failure | Replace with new, properly sealed flashing | Use mechanical fasteners in addition to adhesives |
By promptly addressing storm damage and incorporating appropriate reinforcements, restored built-up roofs can provide long-lasting protection against future weather events.
Choosing the Best Materials for Long-Term Durability
The success and longevity of a built up roof restoration project depend largely on the quality and suitability of the materials used.
In New Orleans’ humid subtropical climate, it’s essential to choose products that can withstand high moisture levels, UV exposure, and temperature fluctuations.
Some key materials to consider include:
1. Moisture-resistant bitumen formulations
2. High-strength, rot-proof reinforcing fabrics
3. Reflective coatings with excellent UV stability
4. Granules or aggregate surfacing for added protection
Working with a knowledgeable contractor who understands the specific demands of the local climate can help ensure that the most appropriate and durable materials are selected for your restoration project.
| Material Property | Benefit for New Orleans Climate | Recommended Products |
|---|---|---|
| Moisture resistance | Prevents blistering and premature aging | Polymer-modified bitumen, synthetic fabrics |
| UV stability | Resists sun damage and deterioration | Acrylic or silicone coatings, ceramic granules |
| Thermal expansion compatibility | Accommodates temperature swings without cracking | Elastomeric membranes, flexible sealants |
While higher-quality materials may come with a higher upfront cost, their enhanced durability and performance can lead to significant savings over the life of the roof.
Making the Right Choice for Restoration Vs Replacement
When faced with a damaged or aging built-up roof, property owners must decide whether to opt for restoration or a full replacement.
In many cases, restoration is the more advantageous choice, offering benefits such as:
- Lower upfront costs (typically 50-70% less than replacement)
- Shorter project timeline and less disruption to building operations
- Extended roof lifespan, often comparable to a new roof
- Reduced environmental impact by minimizing waste and resource consumption
However, there are situations where replacement may be necessary, such as when:
1. The roof has exceeded its serviceable life (usually 20-30 years for BUR)
2. Damage or deterioration is too extensive for repair
3. The building’s use or occupancy has changed, requiring a different roofing system
A professional roofing contractor can help assess the condition of your built-up roof and provide guidance on whether restoration or replacement is the most suitable option.
