About this service
Roof coatings — acrylic, silicone, and polyurethane systems — are applied over sound existing roofs to restore reflectivity, seal minor weathering, and extend service life. They're common on flat and low-slope commercial roofs and some residential applications.
A qualified contractor should evaluate the complete roof assembly before recommending work. The visible symptom may begin at flashing, drainage, ventilation, fasteners, or materials several feet from where moisture appears indoors.
What it generally involves
- Verifying the existing roof is a sound candidate for coating
- Cleaning and repairing the surface and seams
- Applying primer and coating to the specified thickness
- Detailing penetrations, drains, and edges
Things to consider
- Coatings are not a fix for saturated insulation or structural problems.
- Product choice depends on the existing roof material and ponding behavior.
- Coating warranties come from manufacturers and applicators — ask for details.
- Ask the contractor about permits and code requirements that apply in your city and county.
What to ask before work starts
- • What condition is causing the problem, and how was it confirmed?
- • Which materials, preparation steps, and disposal costs are included?
- • What workmanship coverage applies to this specific type of roofing work?
- • Are permits, weather protection, cleanup, and final inspection included?
Common questions
Can any roof be coated?
No — the existing roof must be structurally sound and reasonably dry. A contractor can test and tell you whether coating is viable.
How long does a roof coating last?
Service life varies by product and thickness, often a decade or more before recoating. Your contractor can discuss specific systems.
Does this site apply roof coatings?
No. Coatings are applied by the independent contractors you connect with.
