Roof restoration and roof coating cost in 2026
Most homeowners pay $1,500 to $10,000 to restore a roof, typically a third to a half of what a full replacement costs. A roof coating alone costs about $0.65 to $5 per square foot installed: acrylic is cheapest, while silicone and polyurethane cost more. Here’s what each option costs and how to tell whether restoring or replacing is the smarter spend.
Roof restoration cost by system
Restoration costs depend mostly on the roof type and how much repair comes before the coating. Typical installed prices:
| Restoration type | Typical cost | Notes |
|---|---|---|
| Flat or low-slope roof coating | $0.65 – $4.50 / sq ft | Acrylic is cheapest; silicone costs more and handles ponding water |
| Metal roof recoating | $1.50 – $3.00 / sq ft | Cleaning, rust treatment, seam and fastener sealing, coating |
| Tile roof restoration | $2,500 – $5,000 | Repairs, replaced tiles, cleaning, coating; big jobs reach $11,000 |
| Full restoration (repairs + coating) | $1,500 – $10,000 | Typical all-in range for an average home |
| Asphalt shingle rejuvenation | $550 – $2,500 | Sold as a life extender; the asphalt roofing industry advises against it (see below) |
Installed ranges for single-family homes, compiled from published 2026 industry cost data and typical contractor pricing. Condition, roof size, and local labor move the number.
The residential coating prices here, about $0.65 to $4.50 per sq ft for a flat or low-slope roof, differ from full commercial coating restoration systems, which typically run about $2 to $6 per sq ft (see commercial roof replacement cost).

How much does it cost to get your roof coated?
Professional roof coating costs about $0.65 to $5 per square foot installed, or roughly $650 to $5,000 for a 1,000 square foot roof. The spread comes from the coating type, the cleaning and repairs needed first, and how many coats the system calls for. The material itself is a small share of the bill; most of the price is prep and labor.
| Coating | Installed (per sq ft) | Material only (per sq ft) | 1,000 sq ft roof, installed | Best for |
|---|---|---|---|---|
| Acrylic | $0.65 – $3.00 | $0.15 – $0.80 | $650 – $3,000 | Roofs that drain well; sunny climates |
| Silicone | $1.50 – $4.50 | $0.50 – $1.40 | $1,500 – $4,500 | Flat roofs with ponding water |
| Polyurethane | $1.50 – $5.00 | $0.45 – $1.30 | $1,500 – $5,000 | Foot traffic and impact resistance |
| Asphalt or aluminum | $1.00 – $2.50 | $0.85 – $1.50 | $1,000 – $2,500 | Built-up and modified bitumen roofs |
Installed and material prices per square foot of roof, compiled from published 2026 industry cost data and typical contractor pricing. The 1,000 sq ft column multiplies the installed range by 1,000 and excludes repairs.
Acrylic, silicone and polyurethane roof coatings are all elastomeric, meaning they stay flexible as the roof expands and contracts. “Elastomeric” on a label describes that behavior rather than one chemistry, so check the data sheet for the type. The International Residential Code requires each type to meet its own ASTM standard (D6083 for acrylic, D6694 for silicone, D6947 for moisture-cured polyurethane) and to be installed to the manufacturer’s instructions. Read more about each type on our roof restoration page.
How much does a 5-gallon bucket of roof coating cover?
A 5-gallon pail usually covers roughly 240 to 475 square feet, depending on the product, the surface and the number of coats. Coverage depends on how thick the coating has to go on: one gallon spread over 100 square feet makes a wet film about 16 mils thick (a mil is a thousandth of an inch), and every manufacturer sets a minimum thickness. Two examples from published technical data sheets:
- 100% silicone (Henry 887 Tropi-Cool): about 320 square feet per 5-gallon pail, applied in one coat at 1.5 gallons per 100 square feet.
- 100% acrylic (Henry 587 Dura-Brite): about 475 square feet per 5-gallon pail per coat on smooth surfaces, with two coats required, so roughly 240 square feet per pail for the finished job. Rough surfaces take about 1.5 gallons per 100 square feet per coat.
At those rates a 1,000 square foot roof needs about 15 gallons of that silicone or 20 gallons of that acrylic, plus extra for rough areas, seams and repairs. Your quote should name the product, the number of coats and the target thickness.
Is it worth getting your roof coated?
Yes, if your roof is flat, low-slope or metal, the deck and insulation are dry and sound, and the wear is on the surface. At $0.65 to $5 a square foot, a coating can buy 10 to 15 years on a roof that would otherwise need a tear-off, and a white coating reflects the sun’s heat. No, if the insulation is wet, the deck is soft, leaks are widespread, or the roof is asphalt shingle. Coating over those problems only delays a replacement you will still pay for.
Shingle roofs are the common trap. The Asphalt Roofing Manufacturers Association strongly advises against field-applied coatings and rejuvenators on installed shingles, notes that there is limited documentation of the claimed benefits, and reports problems such as curling, loosened granules and trapped moisture. Both coating data sheets above say not to use the product over shingles of any kind. If a shingle roof is worn, compare a repair with a replacement instead.
Restore or replace? The math
Restoration wins on price because it skips the two most expensive parts of a new roof: tear-off and all-new material. If your roof would cost $15,000 to replace, a restoration in the $4,000–$8,000 range that adds 10–15 years of life is often the better spend, if the roof qualifies.
Restoration is the right call when: the deck and structure are sound, wear is on the surface (a weathered membrane or coating, chalky paint on metal, minor leaks at seams), and you want more years without the cost and disruption of tear-off.
Replacement is the right call when: decking is soft or rotten, insulation is wet, leaks are widespread, or the roof is past its structural life. Restoring a roof that’s truly done just spends money twice.
Not sure which side you’re on? A professional inspection settles it, and comparing quotes for both options is the honest way to see the real price gap on your home.
What moves the price
Roof size and pitch. Coatings are priced per square foot; steeper or taller roofs add labor and safety equipment.
Condition and prep. The more cleaning and repair needed before coating (seams, flashing, wet spots, replaced tiles), the higher the bill.
Coating type and thickness. Silicone and polyurethane cost more than acrylic, and a system with a primer and two coats costs more than a single coat.
Location. Local labor rates vary widely, which is one reason quotes for the same roof can differ.

Roof restoration and coating cost: FAQs
How much does roof restoration cost?
Most homeowners pay $1,500 to $10,000 for a full roof restoration, repairs plus cleaning and a protective coating, depending on roof size, material, and condition. Tile restorations run $2,500–$5,000, and coatings about $0.65–$5 per square foot installed depending on the coating.
How much does it cost to get your roof coated?
About $0.65 to $5 per square foot installed, or roughly $650 to $5,000 for a 1,000 square foot roof. Acrylic is the cheapest at about $0.65 to $3, silicone runs about $1.50 to $4.50, and polyurethane about $1.50 to $5, before any repairs the roof needs first.
How much does a 5-gallon bucket of roof coating cover?
Roughly 240 to 475 square feet, depending on the product, the surface and the number of coats. One silicone coating’s data sheet lists about 320 square feet per 5-gallon pail in a single coat. One acrylic lists about 475 square feet per pail per coat on smooth surfaces, with two coats required, so about 240 square feet per pail for the finished job.
Is it worth getting your roof coated?
Yes, on a flat, low-slope or metal roof with a sound deck, dry insulation and wear that is only on the surface: a coating costs a fraction of a replacement and can add 10 to 15 years. No, if the insulation is wet, the deck is soft, leaks are widespread, or the roof is asphalt shingle.
Is restoring a roof cheaper than replacing it?
Yes, restoration typically costs a third to a half of a full replacement because there’s no tear-off, less labor, and less disposal. A roof that would cost $15,000 to replace can often be restored for $4,000–$8,000 if the structure and most of the surface are still sound.
How long does a roof restoration last?
A quality restoration typically adds 10–15 years of life, and coating systems can often be re-applied at the end of that window for less than the first application. Sellers of shingle rejuvenation treatments claim several added years, but the Asphalt Roofing Manufacturers Association advises against treating installed shingles.
Does insurance cover roof restoration?
Insurance covers sudden, accidental damage (storms, hail, fallen trees), not wear and age. If storm damage is the reason your roof needs work, an insurer may pay for repair or replacement rather than restoration. Document damage promptly and get a roofer experienced with claims.
