A roof treatment comes with its own warranty, and your shingles came with a different one. The two can interact, and that is where homeowners get surprised. A treatment warranty covers the work and product of the company that applied it. Your manufacturer warranty covers defects in the shingles. Before you pay for any treatment, find out which warranties you have, what each one excludes, and who will answer the phone if a claim comes up.
This guide is for South Florida homeowners with aging asphalt shingle roofs who are weighing preservation against replacement. We will be straight about the risks, including the ones the roofing industry raises about our own category.
TL;DR
- A treatment warranty and a shingle manufacturer warranty are separate contracts. Read both before you decide.
- The shingle industry's trade group advises against field-applied coatings and rejuvenators. A treatment can give a manufacturer an argument against a future claim.
- Most roofs old enough to need preservation are already past, or near the end of, any manufacturer coverage. Your real protection is documented maintenance.
- In Florida, your insurer's view of the roof's remaining life can matter as much as any warranty.
- Our 6-year transferable warranty covers the Fresh Roof application. Ask for the written terms from anyone you consider.

Two kinds of roof warranty, and why they get confused
When homeowners search for "roof treatment and warranty," they usually mix up three things. Separate them first.
| Warranty | Who issues it | What it covers | Typical gap |
|---|---|---|---|
| Manufacturer (material) warranty | The shingle maker | Manufacturing defects in the shingles | Often limited, pro-rated over time, and conditional on proper maintenance |
| Workmanship warranty | The installing roofer | Installation errors | Usually much shorter than the material term, and ends if the company closes |
| Treatment or renewal warranty | The company that applies a preservation product | The application and, as written, the treated shingles' performance | Terms vary widely, so read exclusions and transferability |
Top-ranking guides on roof warranties describe manufacturer coverage as lasting 20 to 50 years at the headline level. We would not rely on that number. Headline terms are not the same as what you can collect. The National Roofing Contractors Association (NRCA) notes that long-term product warranties do not by themselves ensure satisfactory performance, and that they often limit the manufacturer's liability and the remedies available to you.
That last point changes how to think about the whole question. A warranty is a document that limits what a company owes you. A maintenance record is evidence that you did your part.
Will a roof treatment void your shingle warranty?
Here is the honest answer: it can create a problem, and you should know exactly how.
The Asphalt Roofing Manufacturers Association (ARMA) strongly advises against applying coatings or rejuvenators to installed asphalt shingles. It says these products can affect fire classification, impact resistance and algae resistance, and that a treatment may void the manufacturer's warranty if it is cited as the cause of later damage such as curling, cupping or granule loss.
One major manufacturer's technical bulletin lists field coating of installed shingles as not recommended. Read the wording carefully: the concern is about damage attributed to the product, not an automatic cancellation the moment someone applies it.
In practice, that means:
- A treatment may not "automatically" void a warranty.
- It does give the manufacturer an alternate explanation for any later problem.
- If you file a claim for blistering, curling or granule loss after a treatment, you may have to show the cause was a factory defect and not the product.
We will not tell you this risk is imaginary. We will tell you how to weigh it.
Check whether you still have anything to protect
This is the question that settles most cases. Ask three things:
- How old is the roof? Many Florida shingle roofs are 12 to 25 years old when owners start asking about replacement. Our guide to shingle roof lifespan in Florida explains why the sun and heat here shorten the range.
- Is the warranty still active? Many are pro-rated, transfer only once, or require registration. Find the original paperwork or call the manufacturer with the installation date.
- Would a claim realistically pay? A pro-rated, material-only warranty on a 15-year-old roof may cover little more than a few defective shingles, not labor or a tear-off.
If your roof is young and the coverage is real, treatment is probably premature anyway. If the roof is older and the manufacturer coverage is expired or thin, the trade-off looks very different. You have less to lose and a replacement bill of $15,000 to $30,000 to avoid.
What a treatment warranty should say
A good treatment warranty is specific. Before you sign with any provider, get the following in writing.
- What is covered. The product, the labor, or both? Does it cover the roof's performance (cracking, curling, granule loss) or just the application?
- How long it lasts. Our own is 6 years. Compare terms in years, not marketing adjectives.
- Whether it transfers. A transferable warranty can help when you sell. Ours is transferable.
- What voids it. Look for requirements such as storm damage, other contractors' work, or missed inspections.
- How to file a claim. Who you call, what you submit, how fast they must respond.
- Who stands behind it. Is the product maker involved, or only the applicator?
- What it says about your shingle warranty. A reputable provider will discuss this directly, not dodge it.

Why Florida insurance matters as much as the warranty
In South Florida, your homeowners insurance often sets the deadline for your roof, not the shingle manufacturer.
Florida's Office of the Insurance Consumer Advocate explains in its four-point inspection guide that an insurer may require documentation confirming at least five years of remaining useful life for roofs past a certain age. For shingles, the commonly applied line is 15 years. Failing that standard can mean repairs before a policy is issued, or trouble at renewal.
Two consequences follow:
- A treatment is not an insurance document. Whether a treated roof satisfies your insurer depends on the inspector's assessment of the whole system and on your carrier's rules. Ask your agent before you commit, not after.
- A free assessment can double as an early warning. Knowing your roof's condition before the four-point inspection lets you plan. See our guide to passing Florida's 4-point roof inspection with preservation, not tear-off, and the one on proving five years of remaining life.
There is also a discount angle. The Florida Insurance Consumer Advocate says homeowners should be proactive about storm mitigation and ask whether improvements qualify for credits. Do not assume a treatment earns a wind mitigation credit. Ask your insurer which improvements it recognizes, and see our piece on wind-rated shingle checks for how inspections work.
Our perspective: warranties are not maintenance
We are not roofers or roof cleaners. We are the company homeowners call before they call the roofer, and that gives us a particular view of warranties.
Most people who call us have the same belief: a roof that is 15 years old has to be replaced, and the warranty will help. Usually neither is true. The roof is often still maintainable, and the warranty, if it exists, is thin.
What we see in South Florida is steady drying. Sun, heat, rain and storms pull flexibility out of asphalt shingles. They get brittle, crack, curl and shed granules. That is aging, not a factory defect, and aging is exactly what manufacturer warranties tend not to cover.
Our approach is to inspect, assess, and then tell you whether the roof qualifies. Some roofs do not. If the shingles are too far gone, or the deck has problems, we say so, and replacement is the right call. We would rather lose a job than put a product on a roof that cannot benefit.
For roofs that qualify, we apply Fresh Roof's Green Soy Technology as a certified applicator. Our position, based on the product's published lab results, is that it restores about 50% of shingle flexibility, compared with about 20% for standard rejuvenation oils. That is a claim about a product, and we would encourage you to ask any provider, including us, for the test documents.
The warranty we stand behind is 6 years and transferable. We think a shorter, clear warranty from a company that inspects honestly is worth more than a long one with exclusions you only learn about later. And we agree with the industry's caution on one point: treat the manufacturer-warranty question as a real decision, not a footnote.

Documented maintenance is your best protection
The NRCA recommends inspecting roof systems at least twice a year, ideally in spring and fall, and after severe weather such as hurricanes. It also notes that most warranties require roofs to be properly maintained. In South Florida, a post-storm check matters as much as the calendar.
What to look for, and write down with dates and photos:
- Curling or cupped edges
- Missing or lifted tabs
- Bare spots and granules collecting in gutters or at downspouts
- Debris packed into valleys
- Damaged flashing or exposed nail heads
- Stains on ceilings or in the attic after heavy rain
Keep the records in one folder: install date, shingle brand and product line, warranty paperwork, inspection notes, receipts. If you ever need to show a manufacturer or insurer that you met your maintenance obligations, that folder does the arguing for you.
Our roof longevity checklist and storm season inspection steps walk through this in detail. After a named storm, use our post-storm inspection checklist.
Leaks and moisture are a different problem from aging shingles. If water has already gotten in, you may need a specialist in repair and restoration, such as a provider of roof repair and water damage restoration, before any preservation work makes sense. Treating a roof with active water intrusion only hides the symptom.
Treat, repair, or replace: a simple decision guide
| Your situation | Likely best step |
|---|---|
| Roof under about 10 years old, manufacturer warranty active, no visible wear | Keep the warranty intact. Inspect twice a year and document it. |
| 12 to 20 years old, some curling or granule loss, shingles still flexible, no leaks | Get an assessment. Preservation may qualify. |
| Warranty expired, insurer asking for remaining life documentation | Assess first, then talk to your agent about what documentation they accept. |
| Widespread cracking, soft or damaged decking, active leaks | Repair or replace. Preservation is not the answer. |
| Storm damage from a named event | File with your insurer and get a damage assessment before any treatment. See our damage assessment workflow. |
One rule runs through all five rows: inspect before you decide. A treatment applied to the wrong roof wastes money, and a replacement ordered for the right roof wastes more.
Questions to ask any provider before you sign
- Are you certified by the product's manufacturer to apply it?
- Can I see written test results, and who ran them?
- What does your warranty exclude, and does it transfer?
- What will you say if my shingle manufacturer asks about the treatment?
- Will you inspect the roof first and tell me if it does not qualify?
- Do you carry the licensing and insurance Florida requires for the work you do?
- How will you document the roof's condition before and after?
A provider who answers all seven without hesitation is worth considering. One who dodges the fourth is telling you something.
Find out if your roof qualifies
We offer a free roof assessment for homes in Broward and Palm Beach counties. We inspect the shingles, assess their condition, and tell you whether the roof qualifies for renewal with Fresh Roof's Green Soy Technology. If it does, you could save up to 80% compared with full replacement, and the work comes with our 6-year transferable warranty.
Schedule your free roof assessment and bring your shingle warranty paperwork if you have it. We will go through both together. We also serve homeowners in Boca Raton, Delray Beach and Plantation.
FAQ
Does a roof treatment void my shingle manufacturer's warranty?
Not automatically, but it can weaken it. Industry bodies such as ARMA advise against field-applied coatings, and manufacturers may point to a treatment as the cause of later curling or granule loss. Check your warranty text, ask the manufacturer in writing, and weigh that against how much coverage the roof actually has left.
What do roof warranties usually cover?
Manufacturer warranties generally cover defects in the shingle materials, often pro-rated over time. Workmanship warranties cover installation errors. Neither typically covers normal aging or storm damage, which is why homeowner insurance and maintenance records matter.
Can a treated roof still pass a Florida insurance inspection?
It depends on the inspector's assessment of the roof's remaining useful life and on your insurer's rules. Many insurers want at least five years of remaining life on older shingle roofs. Ask your agent which documentation they accept before you pay for any service.
Is our 6-year warranty transferable if I sell my home?
Yes. Our 6-year warranty is transferable, which can be a useful document to hand a buyer. Ask us for the written terms during your free assessment so you can read the exclusions yourself.
