"Excellent service. Friendly, professional, job done right, price very reasonable. Justin left our property clean of debris and moved all our potted plants and deck furniture back in place on his own initiative. His estimates are detailed and thorough, and he is willing to discuss at length whatever concerns the owner has. He is outfitted and equipped with a considerable array of high end tools for every job. We intend to hire him again and again for all our pressure-washing needs (both low pressure and steam cleaning). Give him an A++!"

"Jim and Ian came to our house to perform a “Premium Roof Cleaning.” I specifically chose Chinook Services because of their great reputation, fair pricing and that they perform the cleaning process that is recommended by ARMA/GAF. They called ahead, showed up on time, and did a fantastic job. Both of them were respectful, courteous, hardworking and pleasant. They described what they would be doing, how it works and what I should expect. They answered all of my questions and made sure I was aware of the “5 year no new moss” warranty. I’m glad I chose Chinook Services and I wouldn’t hesitate to have them perform more services in the future. I highly recommend them."

"Was able to give a quote over SMS by sending pictures. Came to house, cleaned the roof and gutters as discussed and with very good quality and gave a breakdown of the job done and how to maintain. Recommend and will most likely do cleaning with him again."

Roof Cleaning questions, answered by experts

Vinegar, bleach, chlorine, barley straw, and a bevy of dedicated algaecides can kill algae, which is the easy part. Preventing algae from returning can be a struggle for some homeowners, but keeping the patio well-maintained and clean is a good first step.

There are several telltale signs that your roof needs to be professionally cleaned. It's best to hire a professional as soon as you notice any indicators of wear to preserve your roof's longevity. Key signs to look for include:

  • Moss, Algae, or Plant Growth: Look for moss growth, black streaks (which are often a type of black algae), or any other plant life on your roof's surface.

  • Dirt and Grime Buildup: A general layer of dirt and grime can accumulate over time.

  • Leaf Buildup: An accumulation of leaves, especially in the gutters, is a clear sign.

  • Buildup Under Shingles: Dirt and debris can get trapped under the edges of your shingles.

  • Shifting Roof Shingles: While this can indicate other problems, it can also be a sign that cleaning and maintenance are overdue.

  • Comparison to Neighbors: If your roof appears significantly dirtier or different from your neighbors' roofs, that’s another sign it may be time for a cleaning.

It generally involves soft washing with eco-friendly detergents to remove contaminants, avoiding high-pressure methods that can damage materials.

Inspect annually for damage, clean debris, and reapply sealant to maintain protection.

A green roof is a roof design that includes a thin layer of vegetation on the roof surface. It’s an environmentally friendly option. Some green roofs may look like they have moss or algae on them, causing neighbors to suggest that you clean the roof. However, you should never try to clean a green roof, as any cleaning methods you deploy will likely kill the vegetation.
