What Restoration Actually Does
Roof restoration is a category of work that takes an existing low-slope or flat commercial roof — TPO, EPDM, modified bitumen, built-up, or weathered metal — and renews it without removal. The process:
- Pressure-wash the existing roof clean of debris and degraded surface material
- Repair seams, flashings, penetrations, and any wet insulation found during infrared scan
- Apply a primer coat (where required by the topcoat manufacturer)
- Apply a fluid-applied membrane coat (silicone, acrylic, polyurethane, or asphalt emulsion)
- Often a second topcoat for warranty thickness — typically 30-40 mil dry film
The result is a continuous, monolithic, fluid-applied membrane that bonds to the existing substrate and adds 10-20 years of additional service life. The original roof stays in place. The cost is roughly 35-50% of replacement.
The Seven-Condition Qualification Test
Not every roof qualifies. Before any DFW commercial roof goes into restoration, we run this seven-point qualification check:
1. Substrate is structurally sound
No active deck rot, no large unrepaired punctures, no failed insulation. Infrared survey confirms.
2. Less than 25% wet insulation
If more than a quarter of the insulation board is wet, the wet sections must be cut out and replaced before coating. Above 25%, replacement starts to make economic sense.
3. Drainage works
If the roof ponds water for more than 48 hours after rain, restoration alone will not solve it. Drainage modifications (added drains, scuppers, or tapered insulation) must be designed in.
4. Existing membrane is compatible with coating
TPO, EPDM, mod-bit, BUR, weathered metal — all generally compatible with silicone or acrylic coatings (with proper primer). PVC is harder to coat compatibly. Some EPDM requires specialized adhesion testing.
5. No active leaks under warranty
If the existing roof is still under manufacturer warranty, coating it usually voids that warranty. We confirm warranty status before recommending restoration. Sometimes leveraging existing warranty toward replacement is the better play.
6. Building is in service
Restoration is faster than replacement and dramatically less disruptive. For occupied buildings (hotels, multi-family, hospitals, data centers), restoration eliminates noise, dust, and the safety risks of tear-off. This is often the deciding factor on large multi-family projects.
7. Owner plans to hold the property 5+ years
For property owners flipping the building inside 24 months, restoration may not deliver the buyer due-diligence value of a fresh replacement. For owners holding 5-15+ years, the math is usually obvious.
Pass all seven and restoration is on the table. Fail any one and replacement is usually the right call. We do not pitch restoration on roofs that should be replaced — that is how owners end up disappointed in 4 years.
The Cost Math: Restoration vs Replacement on a 25,000 sqft DFW Roof
| Approach | Cost / sqft | Total (25K sqft) | Useful Life Added | Disruption |
|---|---|---|---|---|
| Acrylic Coating | $1.75-$3.00 | $44K-$75K | 5-10 yrs | Minimal |
| Silicone Coating | $2.50-$4.00 | $62K-$100K | 10-20 yrs | Minimal |
| Polyurethane (high-traffic) | $3.00-$4.50 | $75K-$112K | 10-15 yrs | Minimal |
| TPO Recover (mechanically attached over) | $5.00-$7.50 | $125K-$187K | 15-20 yrs | Moderate |
| Full TPO Replacement (tear-off) | $6.00-$10.00 | $150K-$250K | 20-30 yrs | Significant |
| Full PVC Replacement (tear-off) | $8.00-$12.00 | $200K-$300K | 25-30 yrs | Significant |
Pricing reflects DFW commercial market 2026, materials and labor included. Steep pitch, complex penetrations, and crane access can push higher.
The Energy Bonus: Cool-Roof Coatings
White silicone and acrylic coatings reflect 80-90% of solar radiation. On a DFW commercial building with heavy summer cooling load, this can cut roof-driven cooling costs 10-30%. For a 25,000 sqft warehouse with $4,000/month summer HVAC bills, that is $400-$1,200/month in savings during peak season — sometimes recovering the coating cost in HVAC savings alone over 5-7 years. ENERGY STAR-listed cool-roof coatings can also qualify for utility rebates and sometimes for federal tax incentives. We help owners run the actual math against their utility bills before recommending the spec.
When Restoration Is the Wrong Call
We have walked off restoration jobs after seeing the substrate. Situations where restoration is genuinely a mistake:
- Wet insulation greater than 25% by area. Coating over wet insulation traps the moisture. Five years later you have widespread substrate failure and the warranty is voided.
- Roof age past useful life of substrate. A 28-year-old built-up roof with widespread alligatoring and surface deterioration is at the end of its life. Coating delays the inevitable but does not solve the underlying degradation.
- Active large leaks not isolated to flashings. If water is coming through the field of the membrane, the substrate has failed. Coating cannot fix a roof that is structurally compromised.
- Building owner expecting 30+ years of new useful life. Restoration is 10-20 years, not a full new roof. Owners who need long horizons should replace.
- Warranty conflict. Some manufacturer warranties require a specific maintenance protocol that excludes coatings, or the existing warranty has remaining time that is more valuable than a new coating warranty.
- Building going through major HVAC retrofit. If the building is about to add 20 new rooftop units (with all the new penetrations that creates), do the replacement at the same time. Coating the old roof and then cutting it up for new HVAC voids most coating warranties.
Restoration Workflow on a JRH Commercial Project
- Initial assessment + infrared survey (week 1). Drone photo + thermographic scan + core sample of insulation. Cost is built into the estimate, refunded if you do not move forward.
- Engineering report + recommended scope (week 2). We deliver a written report with the seven-condition qualification, recommended coating system, projected useful life, and cost estimate.
- Contract + permit(week 3). Permit pulled in the building’s jurisdiction. Manufacturer registration of the warranty initiated.
- Wet insulation cut-and-repair (week 4). Targeted removal of any wet sections, replacement insulation installed, membrane patched.
- Pressure-wash + clean (week 4-5). Substrate prepared per manufacturer spec.
- Primer + base coat (week 5). Applied per manufacturer thickness spec.
- Topcoat (week 5-6). Final coat to warranty thickness; quality control inspection.
- Manufacturer warranty registration (week 6). Final docs submitted; warranty certificate delivered to owner.
- Annual inspection program (ongoing). Many warranties require annual inspection to maintain validity. JRH offers maintenance contracts to keep warranty active.
Total project: 5-7 weeks for a 25,000-50,000 sqft commercial building. Tear-off replacement on the same building would typically run 10-14 weeks with significantly more disruption.

FAQ
What is the difference between roof restoration and roof replacement?
Replacement removes the existing roof system down to the deck and installs a complete new system. Restoration applies a coating over the existing roof to extend its life by 10-15 years. Restoration costs 40-60% less and takes one-third the time, but only works on roofs that meet specific qualification criteria — adequate substrate, no significant moisture intrusion, and proper drainage.
How much does roof restoration cost in DFW?
Silicone roof coating: $2.50-$4.00 per sqft installed. Acrylic coating: $1.75-$3.00 per sqft. Polyurethane: $3.00-$4.50 per sqft. A 25,000 sqft commercial flat roof costs $62,500-$100,000 to restore vs $150,000-$300,000 to replace. Residential restoration is rare and only applies to specific architectural roof types.
How long does roof restoration last?
Most premium silicone coatings carry 10-20 year manufacturer warranties when applied by certified contractors. Acrylic coatings carry 5-10 year warranties. Restoration is not permanent — it extends roof life by a fixed window before the underlying substrate ultimately requires replacement.
Can I restore a residential shingle roof with a coating?
No. Asphalt shingle roofs are not candidates for restoration coatings. The coating cannot adhere properly to granule-surfaced shingles, and the application would void the manufacturer warranty. Shingle roofs are restored only through full replacement. Restoration coatings apply to flat or low-slope roofs (TPO, EPDM, modified bitumen, BUR, metal) and certain specialty residential systems.
Is roof restoration tax-deductible like a full replacement?
For commercial properties, restoration is usually classified as a maintenance expense fully deductible in the year incurred — actually a tax advantage over replacement, which must be capitalized and depreciated unless you qualify for Section 179 expensing. Talk to your CPA. The difference can be significant on multi-property portfolios.
Will a coated roof still pass a buyer’s inspection at sale?
Yes, when applied properly with documentation. A silicone-coated roof with a 15-year manufacturer warranty is treated by commercial appraisers and lenders as having approximately 12-15 years of remaining useful life. Keep the warranty documentation and annual inspection records — they are essential for the buyer due-diligence package.
Can my insurance company require restoration instead of replacement?
No, but the carrier can scope a restoration in their estimate if your roof would qualify under the standard. If you insist on replacement when restoration would be sufficient under the manufacturer’s engineering guidelines, you may need to pay the cost difference yourself. We will tell you honestly which path your roof actually qualifies for.
