Two roof rejuvenation quotes can carry the same total and cover different work. One might measure only accessible shingle slopes. Another might include cleaning but leave a needed flashing repair outside the price. Before deciding which is better value, put the two scopes beside each other and mark every missing answer as unspecified.
This worksheet is for comparing proposals for an existing asphalt shingle roof. It does not establish whether your roof qualifies for treatment. Start with a current assessment and the shingle manufacturer’s guidance, then use the written findings to compare like-for-like work.
Write down the roof being priced
- Property address and the date each contractor assessed it.
- Roof material on the main house, garage, additions and porches.
- Measured roof surface area proposed for treatment, with excluded slopes identified.
- Known leaks, previous repairs and roof sections that could not be inspected.
Living-space square footage is not a roof measurement. Ask how each proposal measured the actual roof and whether its price applies to the same sections. If one contractor includes an attached garage and another does not, resolve that difference before comparing totals. Request a simple marked photograph or roof sketch when a written description leaves the boundaries unclear.

Separate a prerequisite from an optional extra
If a contractor identifies a leak, damaged flashing or missing shingles, ask what work addresses that defect, who will perform it and whether eligibility needs to be reassessed afterward. A surface treatment does not replace those repairs. A bid that leaves them out may look cheaper while leaving you with a separate necessary job.
Keep the numbers beside the roof rejuvenation cost guide, but let the property-specific written scope determine your comparison. A general price range cannot tell you whether a repair, difficult access or a separate roof material is included in your proposal.
Ask about the existing shingle warranty before signing
Identify the shingle manufacturer and product if you can. Ask that manufacturer about the exact proposed field treatment and your applicable warranty. A treatment company’s own warranty is a separate promise; it does not establish manufacturer approval. Keep both answers with the quote rather than relying on an assurance that all warranties remain unaffected.
Our manufacturer guidance article explains why that check matters. ARMA advises against field-applied coatings or rejuvenators on installed asphalt shingles and recommends contacting the manufacturer before proceeding.
Questions for a Tampa Bay property
Provide the full address and ZIP code when requesting work. A city name or a nearby neighborhood does not define a contractor’s service boundary. Mention access through gates, narrow side yards, parked vehicles and any shared roof. These are scope questions to resolve on your property, not reasons to assume every home in a city needs the same treatment.
For other communities, use the Tampa Bay service area guide to find an existing local page and confirm the address with the team.
Frequently asked questions
What should a roof rejuvenation quote include?
It should identify the roof areas, assessment findings, product, preparation, repair prerequisites, exclusions, price, property protection and warranty terms. Ask for missing items in writing before comparing the total.
Is the lowest rejuvenation quote the best value?
Only after you establish that the proposed work and terms are comparable. Resolve missing repairs, excluded slopes and uncertain preparation before deciding on price.
Can I compare treatment and replacement quotes with this sheet?
Use it to clarify scope, but the two services do different work. Ask why the roof qualifies for treatment and what a replacement proposal removes and replaces. Do not treat the totals as interchangeable promises.
Share your address and the concerns you want assessed. Ask Shingle Hero for the findings, any prerequisites and a written scope for your roof.
