a major roof decision
29 direct answers on roof treatment, cleaning, replacement, pricing, warranty, and how the process works — written the way people actually ask.
ROOF TREATMENT
Understanding the preservation option
-
A professionally applied, bio-based oil treatment that replenishes the oils asphalt shingles lose as they age. It restores pliability, improves granule adhesion and water resistance, and extends roof life by 5 years per application, up to 3 applications. It is a USDA Certified Biobased Product.
-
No. It is an oil treatment absorbed into the shingle, not a surface coating or waterproof membrane. Nothing sits on top of the roof, so there is nothing to peel or flake.
-
Independent lab testing of the formulation (PRI, ASTM D4798 accelerated weathering, 3,000 hours) measured 9 times less mass loss, up to 5.8 times less granule wash-off, and 8 times slower oxidation on treated shingles versus untreated shingles from the same roof. See the evidence page for the full results.
-
Condition, not age, decides it. The free assessment checks shingle flexibility, granule coverage, prior repairs, leaks, flashings, and the overall system. Roofs with advanced granule loss or widespread damage do not qualify, and we tell you so with photos.
-
Most average-size roofs are cleaned (if needed), tuned up, and treated in a single visit of about 2 to 3 hours. You do not need to be home, and nothing inside the house is affected.
-
No. Leaks are a repair issue. The included tune-up seals nail pops and addresses pipe boots and flashings; larger repairs are quoted separately. A roof with widespread active leaks usually does not qualify for treatment.
-
Up to three applications, typically about five years apart, for up to 15 added years of roof life. Many of our customers are now on their second application.
-
Yes. The product is bio-based and USDA certified. We protect landscaping, gutters, and siding during application and rinse surrounding surfaces afterward.
-
The treatment soaks into the shingle quickly. We schedule around the forecast and will reschedule rather than apply ahead of heavy rain; light rain after absorption does not affect the result.
ROOF CLEANING
Process, safety, and expectations
-
No. High pressure strips granules and shortens roof life. We use a low-pressure, shingle-safe cleaning process.
-
Gloeocapsa magma, an airborne algae that feeds on the limestone filler in shingles and thrives in Virginia's humidity and shade. It is cosmetic at first, but it holds moisture and is often the first visible sign the shingle oils are drying out.
-
Yes. Cleaning is a standalone service and is often the first step in finding out whether a roof qualifies for treatment.
-
Staining usually improves right away. Moss and lichen are killed by the cleaning and release over the following weeks with rain; we explain the expected timeline in your scope.
-
Yes. Low-pressure house washing and exterior soft-wash cleaning can be added to a roof visit. Ask when you request your assessment.
ROOF REPLACEMENT
Scope, price, materials, and accountability
-
Yes. That is the reason the company exists. We have talked many homeowners out of replacements, including some an insurer or another roofer had recommended. When treatment or cleaning is the responsible answer, that is what we recommend.
-
When granule loss is too advanced, damage is widespread, the roof has been layered or badly installed, or the shingles can no longer hold a warranty. We show you why with photos and give a transparent replacement path.
-
Architectural shingles from the major manufacturers. We walk you through the options, the manufacturer warranty on each, and the price difference before you choose.
-
From an exact satellite measurement plus the roof's pitch, stories, access, layers to remove, decking condition, and selected materials. Every quote follows the same framework so pricing is consistent.
PRICING, WARRANTY & FINANCING
What determines the cost, and what is covered
-
About $1.00 to $1.10 per square foot of roof, or roughly $2,500 to $2,750 for a typical 2,500 sq ft roof, based on 900+ priced projects. See the cost guide for ranges by roof size.
-
No single percentage fits every roof. On typical projects treatment runs about one-fifth of a replacement quote for the same roof, but pitch, cleaning, and repairs move the number. We publish real ranges rather than a best case.
-
We can give a close estimate from satellite measurement and your description, and the free assessment produces a written price after the condition is confirmed.
-
Each treatment application is backed by a written 5-year limited warranty on the performance and flexibility of the treated shingles. Exclusions, remedy, and homeowner obligations are stated in the document you receive, and the warranty transfers to a new owner if the home sells.
-
Yes, through Wisetack, available inside your Roof Renew quote for eligible services. Credit decisions, rates, and terms come from the lender. See the financing page.
PROCESS & SERVICE AREAS
What happens, and where
-
You tell us the address, roof age, and what you are seeing. We measure the roof by satellite, inspect the shingles, granules, flashings, and repairs needed, and give you a written recommendation with the reasoning and the price: cleaning, treatment, repair, or replacement.
-
Not for the work itself. For the assessment, being available by phone is enough; many homeowners prefer to be there to see the findings.
-
Richmond and Central Virginia, Chesterfield, Henrico, Hanover, the Tri-Cities, Powhatan, Charlottesville, Williamsburg, the Northern Neck, Lake Anna, Fredericksburg, and surrounding areas. See service areas for local project pages.
-
Yes. Multi-family, HOA, and commercial asphalt-shingle roofs are a regular part of our work; see the commercial page.
-
Roof Renew is BBB accredited and a Google Guaranteed business; Google verifies licensing, insurance, and background checks before granting that badge.
