We Know What Portland Roofs Go Through Every Season
Portland's coastal climate is one of the most beautiful in New England — and one of the toughest on homes. From the historic neighborhoods of the West End and Munjoy Hill to the established residential streets near Deering and Woodfords Corner, the combination of moisture off Casco Bay, heavy tree canopy, and long Maine winters creates the perfect environment for moss, algae, and black streaks to take hold on roofs and siding. Left untreated, this organic growth doesn't just look bad — it actively breaks down roofing materials and can cost homeowners tens of thousands of dollars in premature replacements. At A Plus Exterior Cleaning, we've spent years working on homes throughout the Greater Portland area, and we understand exactly what these properties need. We don't just treat the surface — we manually remove as much moss as possible before applying our soft wash solution, giving you faster, longer-lasting results than anyone who simply sprays and walks away. Whether your home is a classic Victorian near the Arts District or a newer build in the outer neighborhoods, we treat every property like it's our own.
From roof cleaning to gutter maintenance to permanent lighting installations, A Plus Exterior Cleaning offers a full range of exterior services designed to protect and enhance your Portland home. Every job starts with a free in-person estimate, and we walk you through exactly what your property needs — no guesswork, no overselling.
Moss Removal & Roof Cleaning — If you've noticed dark streaks, green patches, or visible moss buildup on your roof, your home is telling you something important. In Portland, the combination of coastal humidity, shaded lots, and prolonged dampness makes moss and algae growth almost inevitable on homes that go without regular maintenance. The problem goes beyond appearance — moss retains moisture and works its way under shingles, accelerating deterioration and potentially voiding manufacturer warranties. Many companies simply spray a treatment and leave, but that's not how A Plus Exterior Cleaning operates. Our process starts with hands-on moss removal — we physically clear as much organic growth from your roof as possible before applying our professional-grade soft wash solution. This dual approach means you see results faster and the treatment penetrates more effectively, targeting remaining algae and spores at the source. We exclusively use soft washing rather than high-pressure equipment, because high-pressure washing on shingles causes granule loss, weakens the roof structure, and leads to the exact repairs and replacements we're trying to help you avoid. Our goal is simple: extend the life of your roof, protect your investment, and save you from costly replacements down the road. Portland homeowners who stay ahead of moss growth can add years — sometimes decades — to the life of their roof. We've helped clients across the city save tens of thousands of dollars by catching the problem early and treating it correctly.
House Washing — Over time, every Portland home accumulates algae, mildew, and grime on its exterior surfaces. The north-facing walls especially tend to develop green or black biological growth that dulls your home's appearance and can work into siding materials if left too long. Our house washing service uses a soft washing system tailored to the specific needs of residential siding — whether your home has vinyl, wood, fiber cement, or painted surfaces. Unlike pressure washing, which can force water behind siding panels, strip paint, or damage trim, soft washing delivers the right cleaning agents at low pressure to safely dissolve and flush away organic growth at the root. The result is a home that looks dramatically cleaner without any risk of damage to the exterior. Many Portland homeowners are surprised at what their home actually looks like after a professional wash — colors appear brighter, siding looks newer, and curb appeal is restored without a single paintbrush. If you're preparing to sell, refinance, or simply want to take pride in your home's appearance, a professional house wash is one of the highest-return exterior investments you can make. We also take care to protect your landscaping throughout the process — your plants, flower beds, and lawn are treated with the same respect we give the structure itself.
Permanent Lighting Installations — Portland homeowners who have dealt with the annual hassle of hanging and taking down holiday lights know how time-consuming and frustrating it can be. A Plus Exterior Cleaning offers permanent LED lighting installations that put an end to that cycle entirely. Once installed along your roofline, these lights are built to last for years and are completely controlled from your smartphone. Change colors, set schedules, adjust brightness, and switch themes for any holiday or occasion — all with a tap. From Christmas red and green to Halloween orange, Fourth of July red, white, and blue, or simply a warm white for everyday curb appeal, the possibilities are endless. The lights are professionally mounted to complement your home's architecture, and because they're designed for permanent outdoor use, they stand up to everything a Maine winter throws at them. No more dragging out storage bins, climbing ladders in the cold, or paying for seasonal installation every year. One investment covers every holiday for years to come. We handle the entire process from design consultation to final installation, making sure the finished result looks clean, intentional, and exactly the way you envisioned it.
Gutter Cleaning — Clogged gutters are one of the most overlooked causes of serious home damage. When leaves, pine needles, and debris accumulate in your gutters — something that happens quickly under Portland's tree canopy — water has nowhere to go. It backs up, overflows, and can work its way into your fascia boards, soffits, foundation, and basement. A Plus Exterior Cleaning provides thorough gutter cleaning that removes all leaves, dirt, and debris from your gutters and clears your downspouts to ensure water flows freely away from your home. We recommend staying on a regular schedule, particularly after the fall leaf drop and again in the spring, to keep your gutter system functioning the way it was designed to. Protecting your gutters is protecting your foundation — and it's one of the simplest, most cost-effective forms of home maintenance available. When combined with a house wash or roof cleaning, we offer bundle pricing to help you get more done for less.
Our Services for Portland Homeowners
Portland is Maine's largest city, and its neighborhoods — from the West End's Victorian-era homes to the working waterfront, Munjoy Hill to Deering — represent some of the most varied and historically significant housing in the state. They also represent exactly the kind of properties that suffer most from neglected exterior maintenance.
Aaron founded A Plus Exterior Cleaning five years ago after recognizing how widespread moss and algae damage was on Portland rooftops, and how few providers were addressing it correctly. His background as an electrician gave him the technical discipline and zero-shortcuts standard the work demands. His years of rock climbing and outdoor experience gave him the physical confidence to work on the steep, complex rooflines common to Portland's older architecture. Over five years and hundreds of completed jobs across the Greater Portland area, Aaron has helped homeowners avoid tens of thousands of dollars in premature roof replacements by catching and treating organic growth before it causes irreversible damage.
