Roof preservation, explained before you buy
What it costs, what it does, what it doesn't, and how to tell whether your roof qualifies. Everything a homeowner should know before keeping an aging roof instead of replacing it.
What you're probably wondering
The four questions homeowners ask first, each with a straight answer.
Will it actually work on my roof?
It works on asphalt shingles that are aging from the surface but still sound. See how it bonds inside the shingle and encapsulates it.
How it worksWhat if my roof is too old?
Condition matters more than age. Some 20-year roofs qualify; some 12-year roofs don't. The assessment tells you which.
Does my roof qualify?What about my insurance?
Insurers set their own rules on roof age. Your Roof Record gives an inspector dated photos, readings and a registered warranty.
Roof age and insuranceWho it’s for, and who it isn’t
Preservation only works on a roof that is still sound. Every job starts with a roof-life assessment, and some roofs don't pass it.
Usually a good fit
- Asphalt shingle roofs showing age: fading, brittleness, early granule loss
- Roofs past their first several years, once the factory surface has worn in
- Algae or moss streaking that has been washed off first
- Homeowners, landlords and property managers who want to delay a replacement
We'll tell you no if
- The decking is soft or the roof has structural damage
- Granule loss has gone too far for the shingles to be saved
- The roof is so new that it doesn't need treatment yet
- The real problem is a flashing leak. Leaks are repaired first; preservation doesn't fix them
What the job looks like
Six steps, each one on the record.
Roof-life assessment
The dealer inspects the shingles, decking, flashings and granule loss, and tells you whether the roof qualifies.
On the record: photos and a written assessment
Wash and prep
Algae, moss and debris come off, loose shingles are secured and penetrations are repaired.
On the record: before photos of every slope
Baseline readings
Moisture and roof conditions are recorded before spraying. Damp shingles can still be treated; the readings are the starting point for your Roof Record.
On the record: moisture readings at application
Spray application
NANOROOF is sprayed across the roof according to the application protocol.
On the record: material applied, from a meter on the sprayer
Test sample left on the roof
A small sample treated with the same material stays on your roof, so it can be checked as it ages.
On the record: sample ID and location
Warranty registration
The job and its readings are registered to your address.
On the record: warranty number and your Roof Record
Questions to ask any roofer before you sign
Whoever you hire for preservation, these answers tell you whether the work will hold up.
- Will you inspect the decking and show me photos?Preservation only works on a sound roof.
- Is the product applied to a written protocol?Ask to see the steps, not just the product name.
- What gets recorded on my job?Moisture readings, material used and photos should all be documented.
- Who issues the warranty?The installer alone, or the manufacturer too?
- What isn't covered?Leaks, storm damage and structural failure usually aren't.
- Will you tell me if my roof doesn't qualify?An honest contractor turns some roofs down.
- Are you licensed and insured here?Ask for proof of both before work starts.
