A commercial roof is a vital asset for any business, protecting the structure, inventory, and employees from the elements. Over time, exposure to harsh weather conditions, UV rays, and general wear and tear can weaken a roof, leading to leaks and reduced energy efficiency. Instead of a complete replacement, commercial roof restoration offers a cost-effective solution to extend the lifespan of your roof while improving its performance.
Before beginning the restoration process, regular roof maintenance is crucial to identify problem areas and prevent further damage. In this blog, we’ll discuss the benefits of commercial roof restoration, the step-by-step process, and how to determine if restoration is the right choice for your business.
What is Commercial Roof Restoration?
Commercial roof restoration involves repairing and rejuvenating an existing roof to extend its lifespan and improve durability. This process typically includes cleaning, sealing leaks, reinforcing weak areas, and applying protective coatings. Unlike a full roof replacement, restoration is more affordable and environmentally friendly.
Benefits of Commercial Roof Restoration
✅ Cost-Effective: Restoration is significantly cheaper than a complete replacement.
✅ Extended Roof Lifespan: Adds 10-20 years to your existing roof’s durability.
✅ Energy Efficiency: Reflective coatings help reduce heat absorption and lower cooling costs.
✅ Environmentally Friendly: Reduces landfill waste from old roofing materials.
✅ Minimized Business Disruption: Restoration takes less time than a full replacement.
Signs That Your Commercial Roof Needs Restoration
Not every roof qualifies for restoration. Here are some signs that indicate it might be the right solution:
- Frequent Leaks: If leaks occur regularly, sealing and applying a roof coating can prevent further water damage.
- Ponding Water: Flat commercial roofs often develop standing water, which can weaken the structure.
- Visible Cracks or Blisters: Small cracks and bubbles in roofing materials signal wear and tear.
- Increased Energy Bills: Poor insulation and heat absorption can cause higher energy costs.
- Fading or Peeling Roof Coating: Worn-out coatings reduce the roof’s ability to reflect heat and resist moisture.
Types of Commercial Roof Restoration Systems
Different roofing systems require unique restoration methods. Below are the most common types:
1. Elastomeric Roof Coatings
- Applied as a liquid and forms a seamless, waterproof membrane.
- Works well on metal, single-ply, and flat roofing systems.
- Enhances UV protection and reflects heat.
2. Silicone Roof Coatings
- Ideal for roofs prone to ponding water.
- Provides excellent water resistance and energy efficiency.
- Long-lasting and requires minimal maintenance.
3. Acrylic Roof Coatings
- UV-resistant and highly reflective to reduce cooling costs.
- Best suited for sloped roofs with good drainage.
- Requires multiple layers for maximum durability.
4. Spray Foam Roofing (SPF) Restoration
- Expands to fill cracks and gaps, creating a seamless layer.
- Offers excellent insulation and waterproofing.
- Suitable for aging flat or low-slope roofs.
Step-by-Step Commercial Roof Restoration Process
A proper restoration process ensures long-lasting results. Here’s how it’s done:
1. Roof Inspection and Assessment
- A professional inspection determines the extent of the damage.
- The contractor evaluates whether restoration is feasible or if replacement is necessary.
2. Cleaning the Roof Surface
- Dirt, debris, and algae buildup are removed using power washing or specialized cleaning agents.
- Ensuring a clean surface allows coatings to adhere properly.
3. Repairing Damaged Areas
- Leaks, cracks, and weak spots are repaired.
- Flashings and seams are reinforced to prevent future issues.
4. Application of Roof Coating
- A suitable coating (silicone, acrylic, or elastomeric) is applied in layers.
- The coating creates a seamless, waterproof barrier.
5. Final Inspection and Quality Check
- The roof is inspected to ensure proper adhesion and coverage.
- Contractors verify that all repairs and coatings meet industry standards.
Cost of Commercial Roof Restoration
The cost of commercial roof restoration varies depending on factors like roof size, type, and material used. Here’s a general breakdown:
| Roof Type | Average Restoration Cost per Square Foot |
|---|---|
| Metal Roof | $3.00 – $7.00 |
| Flat Roof | $4.00 – $8.00 |
| Single-Ply (TPO/EPDM) | $4.50 – $9.00 |
| Spray Foam (SPF) | $5.00 – $10.00 |
Factors Affecting Cost:
- Extent of Damage: More repairs increase the overall cost.
- Type of Coating Used: Silicone coatings tend to be more expensive than acrylic or elastomeric.
- Labor and Material Costs: Prices vary by location and contractor expertise.
Commercial Roof Restoration vs. Roof Replacement
Many business owners wonder whether to restore or replace their roof. Here’s a comparison:
| Feature | Restoration | Replacement |
|---|---|---|
| Cost | More affordable | Expensive |
| Time Required | 1-2 weeks | Several weeks |
| Disruption to Business | Minimal | High |
| Lifespan Extension | 10-20 years | 20-50 years |
| Environmental Impact | Low waste | High waste |
If your roof has minor damage and is structurally sound, restoration is the better choice. However, if it has widespread structural issues, replacement may be necessary.
Maintaining Your Restored Commercial Roof
Proper maintenance ensures your restored roof lasts for years. Follow these tips:
- Schedule Annual Inspections: Identify issues before they become major problems.
- Keep Gutters and Drains Clear: Prevent water buildup and leaks.
- Monitor for New Cracks or Leaks: Address small problems immediately.
- Reapply Roof Coatings as Needed: Some coatings require reapplication every 10-15 years.
