Maintaining a commercial roof can sometimes feel like a daunting task, but understanding the common commercial roofing problems and knowing how to fix them can make it a lot easier. Let’s dive into some of the most frequent problems you might encounter and simple solutions to keep your roof in top shape.
1. Leaks and Moisture
The Problem
Leaks are probably one of the most common commercial roofing problems. They can occur for various reasons, like damaged flashing, cracked shingles, or clogged drains. Water can seep into your building, causing significant damage to the structure and interior.
How to Fix It
- Inspect Regularly: Check your roof for signs of leaks, especially after heavy rain.
- Repair Flashing: Ensure that the flashing around vents, chimneys, and skylights is intact. Replace any damaged sections.
- Clean Gutters and Drains: Keep gutters and drains clear of debris to prevent water backup.
- Seal Cracks: Use a high-quality sealant to fix any small cracks and prevent water ingress.
2. Ponding Water
The Problem
Ponding water occurs when water collects in pools on your roof and doesn’t drain away. This common commercial roofing problem can lead to roof degradation, leaks, and even structural damage if left unchecked.
How to Fix It
- Improve Drainage: Ensure your roof has adequate drainage systems in place.
- Install Tapered Insulation: Tapered insulation can help direct water towards drains.
- Inspect Roof Slope: Make sure your roof has the correct slope to facilitate water runoff.
3. Roof Shrinkage
The Problem
Roof shrinkage is a common roof issue that happens when the roofing material contracts, which can cause cracking, blistering, and even separation of seams. This is often seen in roofs made from EPDM (rubber) material.
How to Fix It
- Regular Inspection: Regularly inspect your roof for signs of shrinkage.
- Proper Installation: Ensure that the roofing material is installed correctly with enough room to accommodate expansion and contraction.
- Use Compatible Materials: Use materials that are designed to work together to minimize shrinkage.
4. Blow-Offs and Tenting
The Problem
Blow-offs occur when sections of the roof are lifted off due to strong winds, usually because of poor installation or damaged roofing materials. Tenting is when the roof membrane pulls away from the substrate, creating a tent-like appearance.
How to Fix It
- Secure Flashing: Make sure all flashing is securely attached.
- Use Proper Adhesives: Use high-quality adhesives and ensure proper application.
- Professional Installation: Always hire experienced professionals for installation to ensure everything is secured correctly.
5. Poor Installation
The Problem
A poorly installed roof can lead to a multitude of problems down the line, from leaks to blow-offs. This is often due to cutting corners during installation or using subpar materials.
How to Fix It
- Hire Reputable Contractors: Always hire licensed and experienced roofing contractors.
- Check References: Check references and reviews before hiring to ensure quality work.
- Inspect Work: Regularly inspect the work during installation to catch any issues early.
6. Punctures and Penetrations
The Problem
Punctures and penetrations can occur due to foot traffic, dropped tools, or debris. These can lead to leaks and other damage.
How to Fix It
- Limit Roof Access: Restrict roof access to only necessary personnel.
- Use Walkway Pads: Install walkway pads in high-traffic areas to protect the roof membrane.
- Regular Inspections: Regularly inspect for and repair any punctures.
7. Roof Blistering
The Problem
Blisters can form when air or moisture gets trapped between layers of the roof membrane. These blisters can eventually burst, leading to leaks and further damage.
How to Fix It
- Ventilation: Ensure proper ventilation to reduce moisture buildup.
- Repair Blisters: Have a professional inspect and repair any blisters promptly.
- Use Quality Materials: Invest in high-quality roofing materials that are less prone to blistering.
