If you've noticed dark streaks, green patches, or thick moss buildup spreading across your roof, you're looking at more than an aesthetic problem. Moss and algae actively break down roofing materials over time, lifting shingles, trapping moisture, and accelerating the kind of damage that leads to costly repairs or premature replacement. In Maine and Southern New Hampshire, the climate creates near-perfect conditions for organic growth — cold winters, humid summers, and heavily wooded lots mean that moss and black algae aren't just common, they're relentless. A Plus Exterior Cleaning specializes in Moss Removal/ Roof Cleaning, and the approach here is fundamentally different from what most companies offer. Rather than simply spraying a treatment and walking away, the moss is physically removed from your roof as thoroughly as possible before any cleaning solution is applied. This hands-on, detail-oriented process means you see faster results and your roof gets the thorough care it genuinely needs. After five years of servicing hundreds of roofs across Portland, Scarborough, Kennebunk, North Conway, Wolfeboro, and beyond — without a single service complaint — this is a process that's been refined and proven to work.

Physical Moss Removal First: Unlike companies that only apply a chemical treatment, the visible moss is carefully removed by hand before any solution is applied. This dramatically accelerates the timeline for results and ensures a far more thorough clean. Soft Wash Application: High-pressure washing can crack, loosen, and permanently damage shingles. A controlled soft wash system is used to apply roof cleaning solutions safely, eliminating remaining organic growth — including black algae — without putting your roof at risk of pressure-related damage. Free In-Person Estimates: Every appointment begins with a visit to your property. The condition of your roof is assessed in person so you receive an honest, accurate quote and a clear explanation of exactly what needs to be done and why it matters for the long-term health of your home. Transparent Communication Throughout: From the moment you reach out to the day the job is complete, you'll be kept informed every step of the way. Real-time updates, clear timelines, and straightforward answers are standard practice — not an afterthought. Quality Over Volume: A deliberate decision is made to keep the workload manageable so that every roof receives focused, thorough attention. This isn't a company chasing as many jobs as possible — it's one committed to making sure every client is completely satisfied with the results.

The process begins with a free in-person estimate. Before any work is scheduled, your roof is assessed firsthand to determine the extent of the moss and algae growth, identify any areas of particular concern, and give you a transparent breakdown of what the job involves. You'll never receive a generic quote over the phone — the goal is to make sure you understand exactly what you're getting. On the day of the service, physical moss removal comes first. Using careful, methodical technique developed over five years and hundreds of roofs, as much moss as possible is removed by hand. This is the step that most companies skip entirely, and it's the step that makes the biggest difference in how quickly and completely your roof responds to treatment. Following the physical removal, a professional-grade roof cleaning solution is applied using a soft wash system. This low-pressure application is safe for all common roofing materials and is designed to penetrate and kill the remaining organic growth at the root level — including black algae, mildew, and any moss that couldn't be manually removed. It's important to understand that this is a treatment process. The remaining dead growth will continue to rinse away naturally over time with rain and weathering. The end result is a thoroughly cleaned, protected roof — without the risk of shingle damage that comes with high-pressure washing.

Moss and algae don't respect county lines, and neither does the service area. A Plus Exterior Cleaning provides Moss Removal/ Roof Cleaning for residential and commercial properties across a wide region, including Portland, South Portland, Cape Elizabeth, Scarborough, Falmouth, Yarmouth, Westbrook, Biddeford, Saco, Kennebunk, Wells, Kittery, Sebago Lake, Naples, Raymond, and Fryeburg in Maine — as well as North Conway, Conway, Bartlett, Jackson, Wolfeboro, Ossipee, Alton Bay, Tamworth, Freedom, and Madison in New Hampshire. These communities share a common challenge: the damp, forested environment of the region creates ideal conditions for aggressive moss and algae growth. Whether your home sits along the coast in Kittery, near the lakes region around Sebago or Winnipesaukee, or up in the White Mountain foothills around Bartlett and Jackson, the risk of roof damage from unchecked organic growth is real and consistent. If you're unsure whether your property falls within the service area, reach out directly. The goal is to help as many homeowners as possible protect their roofs — and every inquiry is handled personally.

Roof replacement is one of the most expensive home repair projects a homeowner can face — often running into the tens of thousands of dollars. What most homeowners don't realize is that a significant number of premature roof replacements are directly linked to neglected moss and algae growth that was left untreated for too long. Moss holds moisture against your shingles, which accelerates granule loss and shingle degradation. Over time, it lifts the edges of shingles, allowing water to infiltrate the underlayment and eventually the structure of your home. Black algae — that dark streaking you see on roofs across Maine — consumes the limestone filler in asphalt shingles, weakening them from the inside out. Regular Moss Removal/ Roof Cleaning is one of the most cost-effective maintenance investments you can make as a homeowner. Clients who have stayed on top of roof maintenance have avoided repair and replacement costs that would have run tens of thousands of dollars. The modest investment in professional cleaning now can protect you from a much larger financial burden down the road. Beyond the structural benefits, a clean roof improves your home's curb appeal, maintains its market value, and gives you peace of mind knowing that the structure protecting everything you own is in good hands.
