When Coatings Make Sense

The right call isn't always replacement.

Commercial flat roofs past 10–15 years with no major structural damage — coatings restore the waterproof layer without the expense of full tear-off.
Metal roofs with fading paint, minor rust, or panel seam leaks — coatings bond directly to metal, seal seams, and reflect heat.
Aging residential flat or low-slope roofs — porches, additions, sunrooms, and older homes with built-up or modified bitumen roofs.
Buildings where tear-off isn't practical — occupied offices, tenant-filled retail, medical buildings, schools where scheduling around replacement would disrupt operations.
Tight budgets with good substrates — when the underlying roof is still sound, coating extends life at meaningful savings.

Coating Systems

Four systems, matched to the roof.

Every coating install starts with the same non-negotiables: full roof inspection, pressure wash or manual cleaning, leak and seam repair, primer coat where required, then the coating system built in spec-thickness layers.

Silicone coatings — best UV resistance, excellent for Atlanta's sun exposure. 15–20 year service life with proper prep. Ponding-water rated.
Elastomeric acrylic coatings — cost-effective, bright white reflective finish that drops rooftop surface temps 40–60°F in summer. 10–12 year service life.
Urethane coatings — high abrasion resistance for roofs with foot traffic, HVAC units, or maintenance access. 10–15 year service life.
Metal roof restoration systems — primer + rust inhibitor + base coat + topcoat for aging metal roofs.

Our Install Process

What a Mosaic coating install includes.

Inspection + core sample — we confirm the substrate is sound before quoting. If it isn't, we tell you; coating over a failed roof is wasted money.
Repair scope — seam repair, membrane patches, flashing re-seal, pipe boot replacement as needed before coating.
Thorough prep — power wash, dry time, primer application per manufacturer spec.
Spec-thickness coating — applied in the mil-thickness the warranty requires. Cutting corners on thickness voids the warranty.
Warranty-backed work — manufacturer warranties run 10–20 years depending on the system; our workmanship warranty is 10 years.
Cooling bill savings — reflective coatings drop rooftop surface temps 40–60°F, cutting HVAC load by 10–25% during Atlanta's summer peak.

"Our flat commercial roof was failing in spots but still had life left. Mosaic did a coating instead of full replacement — saved us thousands and extended the roof 10+ years."

FAQ

Common questions.

How much does a roof coating cost in Atlanta?

Most commercial flat roof coatings run $2.50–$5.00 per square foot installed, depending on system (silicone, elastomeric, urethane) and prep scope. Compare to $8–$14 per square foot for full flat-roof replacement.

How long does a coating last?

Silicone coatings: 15–20 years. Elastomeric acrylic: 10–12 years. Urethane: 10–15 years. All with proper prep and spec-thickness install. Most manufacturer warranties are renewable with a topcoat refresh at mid-life.

Will a coating fix an active leak?

Only if the leak source gets repaired first. Coatings seal seams, membrane wear, and pinhole leaks, but they won't bridge a failed flashing or deck damage. Our prep scope catches these before coating goes down.

Can you coat a residential roof?

Yes — flat porch roofs, sunrooms, additions, and low-slope residential sections. Pitched residential shingle roofs aren't coating candidates; they get repair or replacement.

How soon can the building be used after coating?

Most coatings are foot-traffic-safe within 24–48 hours, fully cured within 5–7 days. Commercial buildings stay operational throughout the install; we schedule work around business hours when needed.
