Commercial roofs are built to withstand heavy wear and tear, but over time, they can develop issues due to weather exposure, poor maintenance, or the natural aging process. Knowing how to repair a commercial roof effectively can save business owners thousands in potential damages and roof replacement costs. Whether you have a commercial metal roofing system or a commercial flat roofing structure, addressing roof problems early on is critical. In this guide, we’ll cover the most effective strategies for identifying, repairing, and maintaining your commercial roof.
Step-by-Step Guide to Repairing a Commercial Roof
1. Identify the Problem
The first step in any commercial roof repair process is a thorough inspection. Look for common signs of damage such as:
- Leaks or water stains inside the building
- Damaged or missing roofing material
- Pooling water, especially on commercial flat roofing
- Cracks, tears, or punctures in the roof surface
- Mold or mildew growth around seams or drains
Hiring a professional for a roof inspection can help pinpoint specific areas that need attention and ensure that no underlying issues are missed.
2. Choose the Right Repair Materials
Before proceeding with the repair, it’s essential to choose the right materials that match your current roofing system. Commercial roofs come in various types, such as:
- Commercial metal roofing: Durable and long-lasting but prone to rust and corrosion if not maintained properly.
- Commercial flat roofing: Often made from materials like EPDM, TPO, or PVC, which require different repair approaches.
Using compatible materials ensures the repair integrates seamlessly with the existing roof structure.
3. Repair Small Leaks and Punctures
For minor damages like small leaks or punctures, you can use patching techniques specific to your roofing type. For commercial flat roofing, apply a roof patching kit to seal the leak. These kits often include adhesive patches designed for quick fixes on EPDM or TPO roofs.
For commercial metal roofing, rust spots or small holes can be repaired using metal patch kits and sealants. After cleaning the area thoroughly, apply a sealant to prevent further water penetration.
4. Address Structural Damage
Larger issues, such as sagging areas or widespread material degradation, require more extensive repairs. In these cases, you might need to replace the damaged sections of the roof. For example, if water has caused the insulation under the roof membrane to deteriorate, the affected portion should be cut out and replaced.
If your roof is significantly damaged, consider a commercial roof replacement. While repairs can extend a roof’s life, a replacement may be more cost-effective in the long run, especially if the roof is nearing the end of its lifespan.
5. Check the Flashing and Seals
Flashing around chimneys, vents, and skylights is a common source of leaks on commercial roofs. Over time, flashing can crack or come loose, allowing water to seep into the building. Reseal or replace any damaged flashing to restore its protective function.
6. Inspect Drainage Systems
Proper drainage is crucial for commercial flat roofing systems. If water is pooling on the roof, it can lead to significant structural damage over time. Clear out clogged drains and ensure that water flows freely off the roof. If necessary, install additional drains or modify the slope of the roof to improve drainage.
7. Maintain Regular Roof Inspections
Regular inspections and maintenance are essential to avoid future damage. Schedule bi-annual inspections to catch potential problems before they worsen. This practice will also help extend the lifespan of your roof and prevent the need for costly repairs or a premature commercial roof replacement.
When to Consider Commercial Roof Replacement
While repairing a commercial roof can be cost-effective for minor damages, there are situations where a full commercial roof replacement is the best solution. Consider a replacement if:
- The roof is more than 20 years old and showing signs of significant wear.
- There are frequent leaks or recurring issues that repairs cannot resolve.
- The roof’s warranty has expired, and repairs are no longer covered.
- Energy bills have spiked, which could be a sign that the roof’s insulation has deteriorated.
Benefits of a New Commercial Roof Installation
Opting for a new commercial roof installation comes with several benefits, including:
- Improved energy efficiency: Modern roofing materials are better insulated, reducing your energy costs.
- Enhanced durability: New roofs are designed to withstand extreme weather conditions.
- Long-term savings: A new roof reduces the need for frequent repairs and maintenance.
When replacing your roof, consider energy-efficient materials like reflective coatings for commercial flat roofing or corrosion-resistant metals for commercial metal roofing. These materials provide long-term protection and help reduce heating and cooling expenses.
