Elastomeric roof coating is a flexible, waterproof coating system designed to help protect large roof surfaces from water infiltration, ultraviolet exposure, and the stress of repeated temperature swings. For industrial and commercial property owners, a roof represents a significant capital investment, and the coating applied to it plays a direct role in how well that investment holds up over time.
What is Elastomeric Roof Coating?
Elastomeric roof coating is a thick, flexible liquid-applied membrane rolled or sprayed over an existing roof to seal it and extend its life.
Elastomeric coatings can stretch and rebound as a roof expands and contracts, they are widely used on large-format metal and low-slope roofs where rigid coatings would eventually crack. Induspray provides elastomeric roof coating services for industrial and commercial facilities, applying coating systems intended to extend roof service life and reduce ongoing maintenance needs.
Industries That Use Elastomeric Roof Coating
- Manufacturing Plants
- Expansive metal roof assemblies
- Constant thermal cycling from weather and internal heat
- Flexibility and strong adhesion are essential
- Warehousing Facilities
- Large low-slope or metal roofs
- Seamless waterproof membrane helps prevent leaks
- Protects stored inventory from water damage
- Oil & Gas Facilities
- Large processing, storage, and warehouse buildings
- Expansive industrial roof surfaces
- Elastomeric coatings can support broader roof maintenance plans
How the Elastomeric Roof Coating Process Works
- 1. On-Site Inspection & Assessment
- Evaluate the existing roof condition
- Determine whether elastomeric coating is suitable
- Identify required preparation and repairs
- 2. Surface Preparation
- Pressure wash and thoroughly clean the roof
- Remove dirt, debris, mold, and failing coatings
- Prepare the surface for proper bonding
- 3. Roof Repairs
- Secure loose or missing fasteners
- Seal separated seams
- Repair cracks and blistered areas
- 4. Primer Application
- Apply primer when required by the substrate
- Improve adhesion between the roof surface and coating
- 5. Elastomeric Coating Application
- Apply coating evenly across the prepared surface
- Use spray or roller equipment as appropriate
- 6. Final Inspection
- Check for complete and consistent coverage
- Confirm the coating system is properly applied
- Complete the project after final quality inspection
Cost Factors for Elastomeric Roof Coating
| Cost Factor | How It Affects Cost |
| Roof Size | Larger roofs require more coating material, labor, and application time. |
| Roof Condition | Damaged or deteriorated roofs require additional repairs before coating, increasing labor and project costs. |
| Surface Preparation | Cleaning, mold/debris removal, fastener repairs, and seam repairs add to preparation time and overall cost. |
| Coating Type | Different elastomeric coating formulations have varying material costs, durability, and performance characteristics. |
| Application Method | Spray or roller application can affect labor requirements, equipment needs, and project duration. |
| Number of Coats | Primer coats or additional coating layers increase material usage and labor compared with a single-coat application. |
Benefits of Elastomeric Roof Coatings
- Flexibility: Elastomeric coatings can expand and contract with the roof as temperatures change. This flexibility helps reduce cracking and supports long-term waterproofing.
- Waterproofing: The coating creates a continuous membrane that helps prevent water from penetrating seams and minor surface imperfections. This can reduce the risk of leaks and moisture damage. If a roof has significant leaks those would need to be repaired before coating with an elastomeric roof coating
- Energy Efficiency: Many elastomeric coatings have reflective properties that reduce the amount of heat absorbed by the roof. This can help lower cooling demand in the building.
- Extended Roof Life: Coating an existing roof can extend its usable service life without requiring a complete roof replacement. This can also minimize disruption to ongoing facility operations.
- Lower Maintenance: The seamless coating surface can reduce areas where leaks and deterioration commonly develop. As a result, properly maintained coated roofs may require fewer repairs over time.
Get Started
If you’re evaluating elastomeric roof coating for an industrial or commercial facility, Induspray can assess your roof and outline a coating approach suited to its condition and substrate. Contact Induspray to request a consultation and discuss whether elastomeric roof coating is the right fit for your property.
If flooring work is also part of an upcoming project, see Induspray’s Epoxy Floor Coatings page. Facilities considering coating work beyond the roof may also be interested in Induspray’s Commercial Painting services.
