Is your commercial roof a coating candidate?
A coating should begin with an assessment of the roof underneath it. RedCorn Roofing helps commercial property owners and managers in Indianapolis and Central Indiana compare restoration with targeted repairs and replacement. The goal is to choose a scope that addresses the building’s actual condition.
What we evaluate before recommending a coating
- Existing roof material: identify the membrane or metal system, previous coatings, and compatibility requirements.
- Surface condition: review deterioration, open seams, flashing defects, corrosion where applicable, and prior patches.
- Moisture concerns: review leak history and signs of wet insulation or decking, and explain when further investigation is needed.
- Drainage: identify blocked drainage paths and areas of persistent standing water.
- Adhesion and preparation: determine what cleaning, testing, primer, and detail work the proposed system requires.
Preparation is part of the roofing scope
A useful coating proposal describes more than the product applied to the surface. It identifies the preparation, repairs, seam and flashing treatment, application requirements, and areas excluded from the work. Existing defects and unsuitable components need to be addressed before a restoration system is installed.
If the roof needs a localized repair first, review our commercial roof repair process. If you are unsure of the roof type, our TPO, EPDM, and PVC roofing overview explains common membrane systems.
Coating, repair, or replacement?
A targeted repair may fit an isolated defect when the surrounding system remains serviceable. A coating can be considered when the existing assembly and surface are suitable for the selected restoration system. Replacement may be more appropriate when deterioration, trapped moisture, damaged decking, or repeated failures make surface restoration a poor fit.
RedCorn explains the findings and the limitations of each option. Coatings do not correct unsound decking or eliminate the need to address drainage and moisture problems. Explore the broader commercial roof replacement scope when restoration is not suitable.
What affects commercial roof coating cost?
Roof area, access, existing material, cleaning and preparation, localized repairs, penetrations, and the chosen system all influence the estimate. Comparing only a price per square foot can hide differences in included repairs and application requirements. Ask what is included, what must be investigated, and how additional work would be approved.
Plan around the occupied building
Share roof access arrangements, rooftop equipment, tenant schedules, and sensitive areas when requesting an assessment. Weather and surface conditions affect application scheduling. Building use and the selected products also inform how access and work areas are coordinated.
Serving Indianapolis and Central Indiana
We work with businesses, property managers, apartments, HOAs, and commercial owners across Central Indiana. Projects elsewhere in Indiana are considered based on scope and location. Send the address, roof type if known, approximate area, leak history, and any existing warranty documents.
Roof coating questions
Can a coating stop every roof leak?
No. The source, condition of the assembly, and suitability of the existing roof must be evaluated. Defective seams, flashing, wet materials, and drainage concerns may require separate work.
Can an existing TPO, EPDM, or metal roof be coated?
Some assemblies may be suitable, but compatibility is specific to the existing surface and selected product. Preparation, adhesion testing, and manufacturer requirements must be checked before choosing a system.
What warranty comes with a roof coating?
Warranty options depend on the selected system, scope, and eligibility. Ask for the proposed coverage, exclusions, maintenance requirements, and applicable terms in writing before approving the work.
