    Brands the Gorilla Property Services network has worked with across Canada and the U.S.

    Sometimes the high points of your property are left out of sight. It is easy to let roof care fall by the wayside, particularly when you already have a busy schedule. Even a bit of neglect can send your roofing into a downward spiral, but our Gorillas can help!

    Professional Ajax roof cleaning and moss removal services can help to boost your curb appeal, improve condition and prolong the lifespan of your construction materials. Over the course of the year, roofing collects debris but you can also expect moss and algae. Leaving unwanted growth to sit can lead to water damage, rot and leaks. Don’t wait for the worst case scenario – call a Gorilla today.

    Understanding Unwanted Growth

    A bit of moss sprinkled across roof shingles can give a home a rustic look but this is more dangerous than you might think both to aesthetics and to condition. Roof clutter looks terrible and can make a terrible impression on passersby, neighbours and potential buyers. If you are looking to sell (or just want a good spring cleaning), roofing can make a world of difference.

    Organics are designed to hold onto moisture and this is true whether it is alive or dead. Moss thrives in damp environments, so a cluttered roof is prime real estate for this invasive growth to take hold and spread. Depending on the type and condition of your roofing material, moss can weave under and over shingling, reaching and damaging the decking underneath.

    If construction materials are compromised, a heavy handed approach can cause more damage than the moss itself. Using a wire brush or amateur pressure washing technique to remove moss from the roof can take softened wood along with it. A roofing contractor can install roofing but they do not stick around to help with maintenance. When you want the best results, there is a Gorilla crew in your area, ready to swing into action.

    The Gorilla Guarantee: Seeking Out Professional Roof Cleaning Services

    The only good moss, is dead moss! Every day property owners run to hardware stores and gardening centres in search of moss killers. These products claim to work well but they are easy to misuse. From harsh chemicals to soft washing machines, there are a ton of options out there, but these are not always effective.

    An amateur approach to roof cleaning can mean wasting gallons of water and introducing harsh chemicals into your living space. Instead, our Gorilla experts cater your services to the types of roof materials we are dealing with. From clay to concrete or standard asphalt shingles, our specialists can handle it all. Put the pressure washer down and reach for the phone – call a Gorilla today.

    When it is time to remove moss from the roof of your home or business, it means navigating heights and putting yourself in a dangerous situation. When hiring on a professional roof cleaning company, property owners can rest easy knowing that each member of the Gorilla team is outfitted with proper safety equipment and knowledge to get the best results, safely. In addition to experience, our Gorillas are protected with full insurance coverage.

    Common questions

    Roof Cleaning — answered

    Do you use pressure washing on roofs?

    No, never on roofs. High pressure lifts asphalt granules, cracks tile, and can void roofing warranties, doing more harm than the growth it removes. We clean exclusively with soft washing, using low-pressure application and chemistry to remove moss and algae safely.

    Do you offer move-in roof cleaning?

    For Ajax new homeowners, move-in roof cleaning is offered before or after you move in. Since a newly purchased home’s roof maintenance history is usually unknown, a fresh clean gives you a known starting point and a clear view of its condition.

    Can roof cleaning help my home appraise higher?

    In Ajax home appraisals, a clean roof helps indirectly by demonstrating maintenance. It does not set a dollar value, but appraisers note overall condition, and a streak-free roof signals a property that has been cared for rather than neglected.

    What if my roof shows moss return shortly after?

    In Ajax, full moss regrowth in under a year is treated as workmanship coverage, so reach out and we will reassess. Light surface staining returning within months is different: under heavy local tree canopy that is environmental, not a flaw in the cleaning.

    Are the chemicals safe for pets?

    Yes, pets are safe as long as they stay indoors while crews work. Once treated surfaces dry, typically within one to two hours, the area is safe for pets again. Keeping them inside during application is standard precaution for any exterior cleaning.

    Do copper strips work too?

    Yes, copper strips work on the same principle as zinc, releasing trace metal in rainwater to suppress moss and algae below. The effect is much the same. Copper is often cheaper and blends in more discreetly against many roofs, which is why some homeowners prefer it.

    Will my outdoor furniture be safe during cleaning?

    Properly applied, yes, your outdoor furniture is safe. At residential roof-cleaning dilutions the chemistry won’t harm typical patio furniture, and crews work to avoid direct spray. Where furniture sits close to the house, we move or cover it and rinse the area to clear any runoff.

    How will I know if you found roof problems?

    You won’t have to climb up to find out. Because crews are already on the roof for the soft-wash, anything they notice gets photographed and written into the report, so problems are flagged clearly rather than left for you to discover later.

    How often should I have my roof cleaned?

    Most asphalt shingle roofs need cleaning every 3 to 5 years, while tile and metal roofs typically go 5 to 7 years between cleanings. Heavy tree canopy, shade, or damp climates accelerate moss and algae growth and push that schedule shorter.
