Commercial Roof Coating — Preliminary Budget Estimate
Roof size: 15,000 sq ft / 150 roofing squares
| GOOD — Lanco White-Seal Elastomeric Roof Coating | $2.25/sq ft | $33,750 |
| BETTER — Karnak 670HS Karna-Sil Ultra | $3.75/sq ft | $56,250 |

This calculator provides a preliminary budget estimate and screening recommendation based solely on information entered by the user. It is not a roof inspection, moisture survey, engineering evaluation or guarantee that the existing roof is suitable for coating.
Roof coating systems should only be installed over substrates that are suitable for restoration. Wet insulation, damaged decking, severe deterioration, incompatible existing coatings, trapped moisture and other conditions may require corrective work before coating.
Final system selection, preparation requirements, coating quantities, primers, repairs and pricing will be determined after Roof Repair Company inspects the property.
Instant pricing is a preliminary budget estimate based on the roof area entered. Final pricing is subject to roof condition, substrate, access, drainage, existing coating, moisture conditions, repairs, preparation requirements, primer requirements, penetrations, flashing conditions and manufacturer installation specifications.
Major repairs, wet insulation, decking replacement, structural repairs, HVAC work, extensive rust remediation and other concealed conditions are not included in the instant estimate unless specifically stated in the final proposal.
Questions? Call (713) 489-4265 or email office@roof.day.
Restore Instead of Replace
A properly qualified commercial roof may be a candidate for restoration rather than complete tear-off and replacement. Coating can potentially:
- Extend the service life of the existing roof
- Reduce disruption to the business
- Reduce tear-off waste
- Lower project costs compared with complete replacement
- Improve roof reflectivity
- Protect the existing roofing system
Final eligibility requires an on-site commercial roof inspection.

Enter your roof area and you'll see commercial roof coating cost for three restoration systems side by side, from an economical elastomeric roof coating price to premium silicone roof restoration.

Frequently Asked Questions
How much does commercial roof coating cost?
Our instant budget pricing ranges from $2.25 to $5.00 per square foot depending on the system: acrylic elastomeric, high-solids silicone or 100% silicone. Final cost typically depends on roof condition, substrate, repairs, primer needs and access, which is why every project is confirmed with an on-site inspection.
How much does silicone roof coating cost?
Our silicone restoration systems are budgeted at $3.75 per square foot for high-solids silicone and $5.00 per square foot for 100% silicone. Actual pricing depends on preparation, repairs and manufacturer installation requirements found during inspection.
What is a roofing square?
A roofing square is 100 square feet of roof area. A 15,000 square foot roof is 150 roofing squares.
Is silicone better than elastomeric coating?
It depends on the roof. Silicone typically holds up better to ponding water and UV exposure, while acrylic elastomeric is a lower initial investment and can be a good fit for roofs with positive drainage. An inspection tells us which system suits your building.
Can silicone roof coating handle ponding water?
Silicone systems are generally much better suited to ponding water than acrylic. Significant drainage problems may still need to be corrected, so we check drainage during the inspection.
Can a commercial roof be restored instead of replaced?
Many commercial roofs can be restored if the existing system is still serviceable, but not every roof qualifies. Wet insulation, damaged decking or widespread failure may require repair or replacement. Final eligibility requires an on-site commercial roof inspection.
How long does commercial roof coating last?
Service life typically depends on the coating system, thickness applied, roof condition, drainage and maintenance. We'll explain what to expect for your roof in the written proposal after inspecting it.
Does my roof need to be inspected before coating?
Yes. An on-site inspection checks moisture, substrate, adhesion, drainage, flashings and repairs so the right system and preparation can be specified for your roof.
