Examination of your roof’s condition

The first step in maintaining the health and longevity of your roof is an inspection. We recommend a minimum of one inspection per year. This increases with the age and roofing material, where your home is located (is it prone to damage from trees?), and weather (heavy wind and hail can do significant damage).

All of our inspections are provided free of charge. If it has been a while since your last inspection or you simply want some peace of mind, call us to schedule an inspection today.

Roof certifications are available if you are selling your house or for insurance purposes if we provide regular inspections, maintenance, and cleaning.

* This certification is based on the findings of a visual evaluation. Due to the limitations of the inspection, we make no guarantee or warranty, expressed or implied, concerning this inspection or the future roof performance and assumes no liability.

Deteriorating roof condition


Pressure washing and moss removal

Our environment and climate are perfect for the growth of moss, lichen, and algae. Once growth starts, acting like a sponge, moss and lichen, if not cleaned, will keep the roof damp maintaining ideal growing conditions. Aside from the unsightly appearance, as this growth can lead to significant damage.

Moss and lichen anchor their roots into the top layers of shingles and remove granule. They grow up into the keyways (slots) of the shingles and along the edges causing them to lift and make the roof more prone to wind damage and leaks. Their growth in valleys will obstruct water flow.

Algae growth can cause health problems for those with asthma and allergies.

Our roof cleaning includes:

  • Complete clean up of debris.
  • Targeted light pressure washing to remove the moss, algae and or lichen.
  • Complete rinse down and inspection of surfaces.
  • Cleaning all gutters and down-spouts.
  • Application of an environmentally safe moss retardant.

Detecting leaks and performing repairs

Rooftop Services is able to undertake any roof repair.

Identifying the source of a leak is not an easy task. Water follows a path of least resistance. This means while you may see the leak in one location, the source of the leak may be a distance away. It also means leaks can show AFTER it has stopped raining.

With over 25 years of experience, we know the most likely sources of leaks and how to find them. That same experience allows us to perform repairs properly the first time out.

If you see paint blistering, have a damp or mildew ‘smell’ in an attic or crawl space, or if you just think you could have a leak, get it checked immediately. The longer you wait to see if you really do have a problem, the more likely there will more damage and possibly a  more expensive repair.

Contact us today with questions, to schedule a repair, or for a free inspection for peace of mind.

Roof Cleaning Myths

Myth #1: Black roof stains are caused by pollution.

Roof stains are caused by a hardy type of algae called Gloeocapsa Magma. All it takes is for one algae spore to land on your shingles and algae will continue to multiply and spread.

Myth #2: Moss on roof shingles is really a signal that it’s time for a new roof.

Simply the presence of moss and algae does not necessarily equate with needing a new roof. In many cases all a roof needs is a good professional cleaning to restore its original look and health. You might notice that roofers don’t like roof cleaners very much, and this is because we keep them honest. If a roofer tells you that you need a whole new roof just because of some algae staining tell him to take a walk and look up your local roof cleaning company instead.

Myth #3: Roof algae removal will have no real impact on a home’s curb appeal.

Most people are shocked when they see how much better their home looks after a roof cleaning. We think this is because most homeowners have gotten so used to seeing the moss on their roof that they’ve completely forgotten how good it once looked.

We’ve lost count of how many times we’ve cleaned the roof of a house that had been on the market for months with virtually no activity and within days of the cleaning it finally started getting serious offers.

No matter how beautiful your landscaping, no matter how clean your windows, no matter how precise the painted trim, if your roof is covered in filthy algae stains then it will still ruin your curb appeal, if not in your eyes then in the eyes of your family, friends, neighbors, and potential buyers.

Myth #4: Roof moss is only a cosmetic issue so it can be ignored for now.

If not cleaned off and kept at bay roof moss has the ability to shave years off the life of your shingles. It’s important to remember that roof moss is a living organism that thrives on the North West warm damp conditions.

Shingle granules are vital to the health of your roof and home because they work to deflect UV rays and heat away from your roof surface. If they are gone or covered with algae then you will have a hotter attic and higher AC bills. You’ll also have to replace the roof a lot sooner, and with the average new roof these days topping $10,000 it’s just a no-brainer to keep your shingles clean and functional for a fraction of the cost.

Myth #5: Roof cleaning will damage shingles, gutters, and landscaping.

If you’re using the right pressure with the proper procedures and techniques then you have nothing to fear.

Myth #6: It’s only necessary to clean the sections of the roof that have visible stains.

Just because you can’t see algae stains on certain parts of the roof doesn’t mean that it’s not already there and beginning to develop.

Keep in mind that in its early stages roof algae is completely invisible to the naked eye. It’s not until the more advanced stages that it actually turns black and becomes visible. So if you can see algae on even one section of your roof that means that it’s probably already taking hold on your entire roof.

Myth #7: We can’t clean a roof in the rain.

We use water to clear the moss and algae off your roof afterwards we apply a moss retardant. The rain will naturally send the powder into the areas most needed.

We prefer not to clean metal roofs in the rain for safety reasons

Myth #8: Roof cleaning is an easy DIY project that any homeowner can do in an afternoon.

There’s nothing easy or quick about roof cleaning. Unless you’re one of these guys that absolutely has to do every home improvement job on his own we would highly recommend that you just find a Licensed Bonded Insured roof cleaning company in your area. Either you can, hire somebody who has the equipment and experience to clean your roof in a few hours or you can spend an entire weekend doing it yourself and risking your life.

Myth #9: Roof cleaning companies tend to overprice their work and take advantage of consumers.

Yes a roof cleaning will cost on average $400-$1500 but we are not trying to rip you off. Each roof is individually inspected. Estimates are based on height square footage and roof feature. ( eg. dorma windows)

When people hear that word “cleaning” they think it should be cheap like carpet cleaning or house cleaning. Think about it. Does a carpet cleaner spend hours at your house sweating his butt off and getting sunburned? No.

Does a carpet cleaner run the possibility of paralysis or death by simply doing his job? No.

Does a carpet cleaner spend $100’s on moss treatments for every single job? No.

There’s so much more that goes into a professional roof cleaning than for any other kind of residential cleaning service that it’s really not even fair to lump them into the same category. We challenge you to name another home improvement service that can instantly transform a home’s curb appeal in a few hours. Can’t be done. When you consider that it not only makes your home more beautiful but also extends the life of your expensive roof by a matter of years, having a roof cleaned is one of the smartest and most cost-effective things that a homeowner could possibly do to protect their biggest investment.

Either you can buy into one of the myths and be disappointed with the results or you can clean your shingles the right way and be satisfied with your new-looking, beautiful home that is free of roof moss and algae.
