Roof Cleaning & Roof Shampoo® FAQ
What makes Roof Shampoo® different from traditional pressure washing or bleach treatments?
Unlike standard pressure washing, which can strip away protective granules from asphalt shingles, or harsh bleach treatments that damage surrounding landscaping and corrode roofing materials, Roof Shampoo® is a gentle, ultra-safe cleaning process. We use a proprietary, eco-friendly formula combined with a specialized low-pressure brush system to clean your roof without causing any damage.
Are the cleaning chemicals safe for my pets, plants, and family?
Yes, absolutely. Our Roof Shampoo® formula is 100% eco-friendly, non-toxic, bleach-free, and phosphate-free. It will not harm your landscaping, pet habitats, family members, or local groundwater supplies during or after application.
Will cleaning my roof actually extend its lifespan, or is it just cosmetic?
It does both! Beyond restoring your home’s curb appeal by eliminating dark algae, lichen, and moss stains, cleaning stops microorganisms from eating away at the shingle matrix. Algae feeds on the limestone filler in asphalt shingles, causing premature breakdown. Removing these organisms preserves your roof's structural integrity.

Roof Restoration & Roof Maxx® Rejuvenation FAQ
How does Roof Maxx® shingle rejuvenation work?
As asphalt shingles age, they lose their natural petrochemical oils, causing them to dry out, curl, and crack. Roof Maxx® is an all-natural, soy-based spray treatment that penetrates deep into dried-out asphalt shingles to restore flexibility and waterproofing capabilities. The application process is clean, quiet, and typically completed in under two hours.
How long does a rejuvenation treatment last, and is it warrantied?
Each Roof Maxx® treatment extends the lifespan of your asphalt shingles by five years and comes fully backed by a five-year transferable warranty. By repeating the treatment every five years, you can extend the life of your existing roof by up to 15 years total.
How do I know if my roof is a good candidate for rejuvenation instead of replacement?
If your roof is between 6 and 20 years old, shows signs of aging (such as minor granule loss or slight drying), but is structurally sound without severe active leaks or structural sagging, it is likely a great candidate. Our team conducts a thorough inspection to ensure rejuvenation is the right solution for your home.

Roof Replacement FAQ
When is a full roof replacement actually necessary?
A full roof replacement is recommended when a roof is past its functional lifespan, has extensive structural damage, severe deck rot, or widespread shingle deterioration that cannot be remediated via repairs or rejuvenation. As GAF-Certified contractors, we evaluate your roof thoroughly and only recommend a replacement when alternative options are no longer viable or safe.
What advantages do I get by choosing Guaranteed Roof for a full replacement?
Because we are GAF-Certified roofing contractors, our installations meet the highest manufacturer standards; we use premium materials and provide comprehensive warranty coverage. We prioritize clear communication, rapid turnaround times, clean worksites, and flexible financing options to make the replacement process seamless and stress-free.
How long does a typical roof replacement take?
For most standard residential properties across Georgia, Tennessee, and the Carolinas, a complete tear-off and installation is completed within 1 to 2 days, weather permitting. We make sure your property is fully protected during the installation and thoroughly cleaned up afterward.

Commercial FAR® Roof Coating FAQ
What is a commercial roof coating, and how does it work?
A commercial roof coating is a seamless, liquid-applied protective membrane applied over existing flat or low-slope commercial roofs. We utilize advanced FAR® Commercial Roof Coatings featuring FiberSeal Base technology—a fiber-reinforced, sprayable membrane that seals cracks, leaks, and seams to deliver superior waterproofing protection.
How much can my business save by choosing a coating over a full tear-off?
Applying a commercial coating generally costs a fraction of a traditional roof replacement. In addition to saving up to 50–70% on total material and labor costs, you avoid business downtime, tear-off debris, landfill disposal fees, and long installation schedules.
Can a commercial roof coating help lower our energy bills?
Yes. Highly reflective commercial coatings bounce solar UV radiation away from the building rather than absorbing heat into the structure. This reduces interior cooling demand during warmer months, leading to lower energy utility bills and reduced HVAC system strain.
