Moss & Algae Removal FAQ for New Orleans Homeowners

How often should New Orleans homeowners get moss & algae removal?
Given New Orleans's year-round heat and humidity — avg high 91°f in summer with extreme dewpoints, most homeowners benefit from moss & algae removal at least once a year. Year-round termite treatment and monitoring (Formosan threat is severe) often makes spring or fall the optimal time to schedule service.
What home types in New Orleans most need moss & algae removal?
Shotgun houses and Creole cottages (architectural signatures of New Orleans) and Double shotguns converted to single-family are the most common home types in New Orleans and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Does moss actually damage my roof?
Yes. Moss holds moisture against shingles, which accelerates granule loss, shingle curling, and eventually rot. It can take years off your roof's lifespan if left untreated.
How long before the moss dies after treatment?
Moss typically dies and begins washing away within 2–4 weeks of treatment. Rain accelerates the process. Full results are usually visible within 4–8 weeks.
Will you physically scrape the moss off?
We typically avoid aggressive scraping, which can damage shingles. Our chemical treatment kills moss and allows it to wash off naturally over time, which is safer for your roof.
Can moss removal be done in winter?
Treatment works best above 40°F. In colder climates, early spring or fall are ideal times for moss removal services.
