Questions to ask before roof rejuvenation.
More companies are offering “roof rejuvenation” in Florida. Some products and applications are serious. Some claims are not. This page is a homeowner checklist, not a product pitch.
Information
Do the homework before anything goes on the roof.
Do not stop at “how much does it cost.” The roof is one of the most expensive parts of the house. Ask who is climbing it, what they are putting on it, and what they will put in writing.
1. Does the applicator hold a Florida State Roofing Contractor license?
Florida law is clear on roofing work. If someone is applying a coating or treatment to a roof, ask to see a Florida roofing license. Look it up. Do not take a truck decal as proof.
If they say “we don’t need a license because we’re not applying a coating,” ask the follow-up: exactly what are you applying to this roof, and why does that not require a roofing license?
2. Was the roof inspected before treatment was recommended?
Rejuvenation is not a substitute for repairing a roof that already has real problems. Before any treatment, someone has to look at the shingles, flashing, penetrations, valleys, ventilation, and deck.
That inspection should be done by a licensed roofing contractor who knows what those parts are supposed to look like. A driveway estimate from a photo is not an inspection.
3. What testing has the product undergone — and what did it pass?
“Tested” is a marketing word until you see the report. Ask what independent testing was performed, who performed it, which tests the product passed, and whether you can see the results.
There are products with serious lab work behind them. There are also products whose claims run ahead of the publicly available testing. Do not be impressed because a flyer says tested.
4. What’s actually in the treatment?
Some rejuvenation treatments use soybean-derived ingredients or soybean oil. That photographs well. Still ask where the feedstock is sourced, where it is processed, and what happens to it before it is applied to this roof.
“Soy-based” is not the same as “grown and processed in the United States.” If country of origin matters to you, ask the manufacturer. Imported raw materials still have to be shipped here before they become the jug on the truck.
5. What’s on the label and SDS — and is it flammable?
Read the product label and the Safety Data Sheet. Some treatments contain ingredients that can be flammable. Know what is going on the house and what the manufacturer requires for application, ventilation, and fire safety before anyone sprays.
6. Is the treatment actually appropriate for this roof?
Rejuvenation is not for every roof. Ask why this one qualifies, and what would make it unsuitable:
- Brittle or deteriorated shingles
- Missing or damaged shingles
- Exposed fiberglass mat
- Damaged flashing
- Active leaks
- Inadequate ventilation
- Deteriorated decking
- Previous repairs that still need work
If the problems are already in the deck, flashing, or missing shingles, a treatment on top does not fix them.
7. What happens if there is already damage underneath?
A treatment should not be used to hide a problem. Ask: if you find damaged shingles or other defects during the inspection, will you repair them before treatment? Get that answer in writing.
8. What does the manufacturer actually say the product will do?
That is different from what the salesperson says. Read the manufacturer’s technical sheet. What does it claim? What does it not claim? Ask about expected service life, warranty, exclusions, application method, and maintenance.
9. Get everything in writing
If someone says this will add a set number of years, that it is equivalent to a new roof, or that it has passed “all the major tests,” ask them to put the claim in writing and point to the document that supports it. A verbal promise is not part of the contract.
When the concept can make sense
There are rejuvenation technologies that have been through serious testing and are meant to restore some of the characteristics of aging asphalt shingles. The idea can be sound when the roof is structurally sound but showing age and weather — not when the roof already needs replacement.
A properly formulated treatment on a qualifying roof can be aimed at:
- Restoring oils and flexibility to weathered asphalt shingles
- Helping reduce brittleness
- Improving the look of an aging roof
- Extending the useful life of a roof that does not yet need to come off
- Doing something different from spraying a coating over a dead roof
Ask all of this
- Who is licensed?
- Who inspected my roof?
- Is my roof actually suitable for treatment?
- What is actually being applied?
- Where do the raw materials come from?
- What testing has been done, and what tests did it pass?
- Can I see the documentation?
- What is on the product label and SDS?
- What happens if damage is found?
- What exactly am I being promised — in writing?
