Moss and lichen hold moisture against shingles and pry up their edges as they grow, which shortens roof life, and some home insurance carriers now flag heavily streaked roofs during renewal inspections. A $400 cleaning that defers a $12,000 replacement by even two or three years pays for itself many times over.<\/p>\n Roof Cleaning Cost Factors<\/h2>\nPitch and height<\/h3>\nA steep roof slows everything down and demands harnesses and anchor points, adding 20 to 40 percent to the price. Second and third stories add ladder time and safety setup. A walkable single story ranch is the cheapest roof in America to clean.<\/p>\n Type and amount of growth<\/h3>\nLight algae streaking is the easy case. Established moss holds moisture against the shingles and has to be killed, allowed to release, and then removed gently, sometimes over two visits. Lichen is the stubborn one, since it bonds to the granules and can take repeat treatments. Each step up in growth adds $100 to $300.<\/p>\n Roof material<\/h3>\nAsphalt shingles take a standard soft wash. Tile roofs cost more because techs cannot walk them freely without cracking tiles. Metal roofs clean quickly but need care around fasteners and finishes. Cedar shakes need the gentlest chemistry of all and often cost the most per square foot.<\/p>\n Access and landscaping<\/h3>\nTight lot lines, pool cages, solar panels, and delicate landscaping under the drip line all add protection work. Crews tarp plants, wet everything down, and rinse after treatment, and that time lands in the price.<\/p>\n Bundled add on work<\/h3>\nMost roof cleaning crews also handle gutters, house washing, and driveway work, and bundling saves real money since the setup cost is already paid. Expect gutter cleaning to add $100 to $250, a house wash to add $200 to $400, and zinc or copper strips for long term algae prevention to add $200 to $500 installed. Booking two or three of these together commonly saves 10 to 20 percent versus separate visits.<\/p>\n DIY vs Hiring a Professional<\/h2>\nThe materials for a DIY soft wash are cheap. A pump sprayer runs $50 to $150, and the cleaning solution costs $30 to $60 per treatment. The problem is everything else. You are handling a ladder, a wet sloped surface, and chemicals that kill grass on contact, all at the same time. Falls from roofs and ladders are one of the most common serious home injuries, and no $400 savings justifies one. A rented pressure washer at $70 to $120 per day is the worse idea dressed up as the cheaper one, since high pressure on shingles causes the granule damage described above.<\/p>\n DIY makes sense only for a single story home with a low pitch, a sturdy setup, and light algae, and even then a spray from the gutter line with no roof walking is the sane limit. For moss, lichen, two story homes, or any steep pitch, hire it out. A pro carries the right chemistry, the right rinse equipment, and the fall protection this work genuinely requires. Roof cleaning is also easy to bundle with gutter cleaning or house washing through our services<\/a> page, and combining jobs on one visit usually beats booking each separately.<\/p>\nRoof Cleaning Prices by City<\/h2>\nHumidity drives algae, and labor rates drive the rest, so the same roof prices differently across the country.<\/p>\n \n\n\nCity<\/strong><\/td>\nAverage Soft Wash<\/strong><\/td>\nTypical Range<\/strong><\/td>\n<\/tr>\n\n| Dallas<\/td>\n | $450<\/td>\n | $300 to $650<\/td>\n<\/tr>\n | \n| Houston<\/td>\n | $500<\/td>\n | $350 to $750<\/td>\n<\/tr>\n | \n| Miami<\/td>\n | $550<\/td>\n | $375 to $800<\/td>\n<\/tr>\n | \n| Tampa<\/td>\n | $525<\/td>\n | $350 to $775<\/td>\n<\/tr>\n | \n| New Orleans<\/td>\n | $450<\/td>\n | $300 to $700<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Dallas sits at the value end because drier air slows algae growth and roofs stay cleaner longer. Houston runs higher since Gulf humidity feeds algae nearly year round and demand for soft washing is constant. Miami tops the list with the heaviest algae pressure in the group plus higher labor costs, and tile roofs common there cost more to clean. Tampa lands just behind Miami for the same humidity reasons, with pool cages adding access work on many homes. New Orleans matches Dallas on price thanks to lower labor rates, even though its humidity rivals Houston.<\/p>\n How Booking Through House Fly Works<\/h2>\nYou tell House Fly what you need, whether that is a soft wash for black streaks or full moss removal.

Light algae on a single story home starts around $250, while heavy moss removal on a large or steep roof can reach $1,000 to $1,200. Soft washing is the standard method for shingles.<\/p>\n What is soft washing and why does it cost more?<\/h3>\nSoft washing applies a diluted cleaning solution at low pressure to kill algae, moss, and lichen, then rinses gently. It costs slightly more than pressure washing because the chemicals and landscaping protection take time and materials. The payoff is that results last two to four times longer, since the growth dies completely instead of returning within months.<\/p>\n Can you pressure wash a shingle roof?<\/h3>\nNo, and any company that proposes it should be a red flag. High pressure strips the protective granules off asphalt shingles, can lift shingle edges, forces water under the roof deck, and may void the manufacturer warranty. Shingle roofs should be soft washed at low pressure, which kills the growth chemically without shortening the roof’s life.<\/p>\n How often should a roof be cleaned?<\/h3>\nEvery 2 to 4 years in humid climates, or whenever black streaks or moss patches become visible from the street. Homes under heavy tree cover or in Gulf Coast humidity land at the short end of that range. A preventive treatment at $150 to $350 between full cleanings keeps algae from reestablishing and stretches the interval.<\/p>\n | | | | |
