Roof coatings and restoration

A liquid-applied layer installed over a compatible roof substrate to renew water resistance or reflectivity. It is not a substitute for correcting wet insulation, open seams, structural slope, or failed flashings.

Back to index

Normal function

A properly specified coating can protect a compatible membrane and extend service life, but only when the substrate, adhesion, drainage, and detailing are sound.

What a homeowner may notice

Surface oxidation, small compatible cracks, worn coating, or minor pinholes on an otherwise sound membrane.
Ponding, wet substrate, open seams, blisters, loose edges, or active leaks that coating alone would conceal.
Coating peeling, alligatoring, or incompatible layers.
No maintenance record or unknown substrate.

Professional inspection

Identify membrane and prior coating, test adhesion/moisture, map seams/penetrations/drains, inspect edge terminations, and verify the substrate is dry and compatible with the proposed product.

Repair or replacement path

Clean and prepare per manufacturer, repair seams and penetrations first, replace wet/unsound material, apply primer/coating at specified rate and weather window, then document thickness and cure.

Typical materials and equipment

Compatible coating, primer, seam tape/mesh, flashing, rollers/spray equipment, fall protection, cleaning/containment, and repair membrane.

When to act

Coating is a planned restoration option, not an emergency leak patch.

Billing unitSquare foot or roof square; seams/edges per linear foot; penetrations each.Invoice language should state what was measured.

Planning range$1.50-$5.00/SF planning range for coating/restoration; repair work extraCharlotte-area guidance, not a quote.

Realistic exampleA 500 SF porch membrane with sound substrate may be coated by SF after seam/edge repairs; ponding correction or wet insulation is a separate project.Actual scope changes after inspection.

Crew and time2-4 techs; one to three days plus cure/weather windows.Weather and access can extend production.

What moves the price

Substrate condition, coating chemistry, moisture, ponding, surface prep, access, number of details, thickness, and manufacturer warranty.
