How to Properly Maintain a Commercial Roof
A proactive approach is the best way to ensure a commercial roof remains in excellent condition. Here’s a step-by-step guide to maintaining a commercial roof:
1. Schedule Regular Roof Inspections
The NRCA recommends inspecting commercial roofs at least twice a year (spring and fall) and after severe weather events. Asheville, NC, experiences a mix of hot summers, heavy rains, and occasional winter storms, making routine inspections crucial.
🔹 What to Check During an Inspection:
✔️ Membrane Condition – Look for cracks, blisters, or punctures in the roofing material.
✔️ Flashing & Seals – Ensure flashings around vents, HVAC units, and chimneys are intact.
✔️ Drainage Systems – Clear clogged gutters and downspouts to prevent standing water.
✔️ Interior Signs of Damage – Check ceilings for leaks, mold, or water stains.
💡 Pro Tip: Hire a commercial roof repair company like Litespeed Construction to conduct detailed inspections and provide an expert report
2. Address Repairs Promptly
Even minor issues can escalate into major damage if left unaddressed. The Federal Emergency Management Agency (FEMA) reports that roof leaks account for nearly 40% of building insurance claims.
🔹 Common Commercial Roof Repairs:
- Replacing damaged membranes
- Fixing leaks around HVAC units or skylights
- Repairing storm or wind damage
- Resealing flashing and expansion joints
💡 Pro Tip: Document repairs and keep a record of all maintenance activities.
3. Keep Gutters & Drains Clear
Clogged gutters lead to standing water, which can cause structural damage and roof membrane deterioration. The U.S. Environmental Protection Agency (EPA) warns that improper drainage can lead to roof collapse in extreme cases
✅ Clean gutters at least twice a year
✅ Ensure downspouts direct water away from the foundation
✅ Install gutter guards to prevent debris buildup
4. Protect Against Ponding Water
Flat commercial roofs are prone to ponding water, which can weaken roofing materials and lead to leaks. The American Society of Civil Engineers (ASCE) states that standing water should be addressed within 48 hours to prevent degradation.
🔹 Solutions:
- Ensure proper slope and drainage design
- Repair sagging roof areas
- Consider installing a waterproof coating
5. Maintain Roofing Materials & Coatings
Different commercial roofing systems require specific maintenance strategies:
| Roof Type | Lifespan (with maintenance) | Common Issues | Maintenance Tips |
|---|---|---|---|
| TPO & PVC | 20-30 years | Seams separating, punctures | Regular inspections, reapply sealants |
| EPDM (Rubber) | 25-30 years | Shrinking, seam damage | Apply protective coatings |
| Metal Roofing | 40-50 years | Rust, loose panels | Check fasteners, repaint as needed |
| Modified Bitumen | 20-25 years | Cracking, blistering | Apply UV-resistant coatings |
