Q: Is roof cleaning safe for my shingles?

Yes, provided it is done using the soft-wash method approved by the Asphalt Roofing Manufacturers Association (ARMA). We never use high pressure on a roof, as it can strip away the protective UV granules and shorten the lifespan of your shingles. Our chemical treatment safely neutralizes Gloeocapsa magma (the bacteria that causes black streaks) and moss. MGM Tip: Cleaning your roof isn't just about looks—it prevents the roots of moss and lichen from lifting your shingles and causing leaks.

Question 1

What is the difference between pressure washing and soft-washing?

Accepted Answer

Pressure washing uses high-pressure water (often over 3,000 PSI) to mechanically blast away dirt from hard surfaces like concrete and stone. Soft-washing uses low-pressure (similar to a garden hose) combined with specialized, biodegradable cleaning solutions to kill organic growth like mold, algae, and moss at the root.

MGM Tip: We use soft-washing for all New Hartford siding and roof projects to ensure your property is cleaned without the risk of high-pressure damage or water injection behind your siding.

Question 2

How often should I have my house washed in Central New York?

Accepted Answer

For most properties in the New Hartford and Utica areas, a professional house wash is recommended once every 12 to 24 months. Because our region experiences high humidity and heavy seasonal debris, organic growth like green algae and black mold can take hold quickly.

MGM Tip: Regular maintenance prevents permanent staining on vinyl siding and keeps your gutters from becoming weighed down by organic buildup.

Question 4

Why are there black streaks on my gutters, and can they be removed?

Accepted Answer

Those dark vertical lines are known as "tiger striping." They are caused by an electrostatic bond between the metal of the gutter and the pollutants in rainwater. Standard pressure washing won't remove them; they require a specialized chemical "gutter brightening" process to break that bond and restore the original finish.

MGM Tip: We include basic gutter exterior cleaning in our house wash, but offer a dedicated brightening service for gutters that have heavy oxidation or striping.

Question 5

Do I need to be home while my property is being cleaned?

Accepted Answer

No, most of our residential exterior cleaning services can be completed while you are at work or running errands. We simply ask that you ensure all windows are tightly closed, outdoor pets are secured inside, and water spigots are accessible. We will provide a digital walkthrough or photos upon completion to ensure you are 100% satisfied.

MGM Tip: Our 2-person truck teams are fully equipped to handle the entire setup and breakdown, leaving your property refreshed without interrupting your day.
