Home / Service
Your roof is one of the most important investments in your home, yet it’s often one of the most overlooked when it comes to maintenance.
At Clarke’s Cleaning Service, Inc., we provide roof cleaning in Monticello, MN that’s both effective and safe. Our gentle methods remove harmful buildup like moss, algae, mold, and black streaks — all without damaging your shingles or voiding warranties.
With over 25 years of experience serving homeowners throughout the Twin Cities metro, we know what Minnesota roofs go through. From humid summers to snowy winters, your roof takes a beating. Our team is here to help you extend its life, boost curb appeal, and protect your property value.

Why Is Roof Cleaning Important?
Over time, your roof can develop dark streaks, green patches, or fuzzy growths. These are signs of algae, lichen, and moss — and while they may look harmless, they can cause serious damage.
Organic buildup on your roof:
Traps moisture that can weaken shingles
Causes premature aging and granule loss
Reduces energy efficiency by trapping heat
Lowers curb appeal and resale value
That’s why professional roof cleaning in Monticello isn’t just about looks — it’s a key part of preserving your entire home.
Safe and Gentle Roof Cleaning with Soft Washing
Protect your roof with our specialized soft washing services, a safer alternative to traditional pressure washing that can damage shingles. Soft washing combines low-pressure water with biodegradable detergents to effectively remove harmful buildup without causing harm.
Here’s why soft washing is the ideal choice for your roof:
Recommended by manufacturers for asphalt, cedar, and tile roofs
Gentle and non-invasive, preserving shingles and flashing
Targets and eliminates organic growth at the root
Eco-friendly and safe for pets and plants
We adhere to industry best practices to ensure your roof remains clean, healthy, and structurally sound. Trust us to keep your roof in top condition while prioritizing safety and sustainability.
Extend the Life of Your Roof

Enhanced shingle performance and insulation
Prevention of rot, mold, and water damage

Let Clarke’s help you protect your investment and enjoy peace of mind year-round.
Our Roof Cleaning Process
There are various methods for cleaning a roof, but not all of them are effective or safe. At Clarke’s, we use a tried and tested process that ensures the best results without compromising your safety or the integrity of your roof.
Roof Assessment and Customized Plan
Our process starts with a detailed roof inspection to identify problem areas and determine the best cleaning approach. We prioritize safety and efficiency, tailoring a plan that meets the unique needs of your roof.
This assessment ensures that every step of the cleaning process is designed to protect your roof while delivering the best results. By understanding your roof’s condition, we can target specific issues like stains, algae, and damage without causing harm.
Application of Biodegradable Cleaners
We use eco-friendly, biodegradable cleaners to treat your roof without harsh chemicals. These cleaners are designed to lift stubborn stains and eliminate algae at the root to ensure long-lasting results.
Our cleaning solution is gentle on your roof and safe for the environment, providing effective treatment without toxic substances. This step is essential for preserving the integrity of your roof while achieving spotless results.
Gentle Soft Wash Rinse
Once treated, your roof is gently rinsed using a soft wash system. This low-pressure method removes dirt, stains, and algae without causing any damage to your roof materials.
Our soft wash rinse ensures your roof is thoroughly cleaned while protecting delicate surfaces. By avoiding high-pressure washing, we maintain the structure of your roof and extend its lifespan.
Final Inspection and Touch-Ups
After cleaning, we conduct a final inspection to ensure every area is spotless. Any remaining issues are addressed with precise touch-ups for a flawless finish.
This meticulous final step guarantees that your roof is not only clean but also in excellent condition. We leave no detail overlooked, delivering results you can trust to last for years.
When to Call for Professional Roof Cleaning
Not sure if your roof needs maintenance? Keep an eye out for these common warning signs that signal it’s time for professional cleaning.
Black streaks or discoloration, moss or lichen on shingles, green patches of algae or mildew, and uneven shading or staining are all signs of potential problems. A noticeable decline in your home’s curb appeal might also suggest your roof could use some attention.
