How Often Should You Clean Your Roof?

November 30, 2016

You may love to experience the four seasons each year in the Pacific Northwest, but your roof doesn’t. Rain, fog, ice, and even shade from large trees can create the perfect environment for moss and fungi to grow.

Moss, mildew, algae, and lichen grow into your shingles and wear away the material. They can even lift shingles. This creates space for water to pool and eventually leak into your home.

People in Portland and Vancouver often ask us: “How often should I clean my roof?”

It’s a good question, but unfortunately, there’s no easy answer. How often you should clean your roof really depends on several factors that affect the condition of your roof. I’ll go over those today so you can decide whether your roof needs cleaning. First, we’ll talk about how to safely and effectively clean a roof.

Let’s dive in!

How Pacific NW Roofs Should be Cleaned

First things first: Any roof expert will recommend that you don’t climb up on the roof yourself. We’ve seen too many serious injuries to people who were being cautious but simply didn’t have the expertise to navigate the roof safely.

It’s especially dangerous in the Northwest too — moss, fungi, and moisture make your roof extra slippery.

At Northwest Roof Maintenance we know how to get the job done right so that your roof will need to be cleaned much less often than if you tried to clean it yourself. Here’s how:

  1. Our roof cleaning treatments are meant to last. For example, when we get rid of moss on your roof, we also apply a follow-up treatment to your entire roof to prevent future moss growth.
  2. We always offer a free full preliminary roof inspection. This allows us to identify even the smallest leaks, cracks, and other issues that may be damaging your roof. We’ll fix any problems we find so your roof will stay strong and clean for longer.

Now let’s figure out how often you should have someone clean your roof.

Factors that Affect Your Roof’s Condition

There are two major causes of dirty and moss-covered roofs:

  1. Excessive moisture that promotes moss, fungi, and bacteria growth
  2. Structural damage that allows water to seep under your shingles or tiles where the sun can’t reach (When there’s damage, we usually recommend our repair services before we clean your roof.)

Here are a few of the most common causes of these issues:

1. Heavy Rainfall

heavy rainfallWater that accumulates on your roof from rain creates the perfect moist environment for bacteria, moss, and fungi to thrive. After extra rainy winters, you might notice a lot more moss and fungus growth on your roof than usual.

The amount of rain that falls on your roof has a big effect on when (and how often) you should get it cleaned.

If you’re not sure whether your roof needs to be cleaned or not, you can always contact us for a free inspection and estimate.

2. Excessive Shade

Many Portland and Vancouver homes are nestled under the cover of large trees. Trees are beautiful — they help keep your home cool in the summer and increase the value of your property. Unfortunately, they can also make it hard for moisture to evaporate off your roof.

If your roof is in a shaded area, you’ll probably need a roof inspection and cleanings more often.

3. Falling Leaves and Other Debris

If you often notice leaves or other debris from trees accumulating on your roof, you may want to think about more frequent roof cleanings. Here’s why:

When leaves cover your roof, they also trap moisture, which makes it easier for moss, fungi, and bacteria to grow, which can roof damage from snowalso cause the development of leaks. As we know, excess moisture equals bad news for roofs in the Pacific Northwest!

4. Other Factors

There are many other reasons you may need either more frequent roof cleanings or extra roof maintenance than normal.

Here are a few:

  • A snowy winter, when snow was on top of your roof for a long period of time
  • An intense wind or hail storm that may have caused damage to your roof shingles, tiles, or shakes
  • Damage to your roof from a fallen tree or branch
  • Any time you notice leaking, missing shingles or other signs of damage

Roof Cleaning Frequently Asked Questions

How do you get rid of moss?

Our moss removal procedure involves a few different steps.

  1. We use a combination of air (from a leaf blower) and soft brushing to loosen moss and blow it out from between your shingles, tiles, or shakes without damaging them.
  2. On cedar shake and cement tile roofs, we may also use high pressure water in extreme cases if necessary. We will NEVER use high pressure water on a composition shingle roof as this can be damaging.
  3. To finish, we’ll apply a preventative treatment over the entire roof to stop new moss growth.

 

What’s the best time of year for a roof cleaning?

It really depends on you and your roof. We often recommend gearing up for winter by getting your roof cleaned at the start of fall. This can really help protect your roof because our moss treatments actually prevent future moss growth! Barring extreme weather, however, you can get your roof cleaned at any time of the year.

The bottom line is, the best time to get your roof cleaned is when your roof needs it!

How do I know when my roof needs to be cleaned?

One of the best things you can do for your roof doesn’t involve much work at all: simply pay attention to it! Keep an eye on your roof. If you notice moss growth, missing or damaged shingles, warped areas, or any other signs of damage, you’ll know it’s time for maintenance.

What Types of Roofs Can You Clean?

At Northwest Roof Maintenance, we clean most types of roofs, including composition roofs, tile roofs, and cedar shake roofs.

Different types of roofs require different types of care. For example, to prevent future moss growth, we use a zinc-based treatment for composition and tile roofs and a copper-based treatment for cedar shakes.

Don’t Neglect Your Roof this Winter!

November 8, 2016

winter

The Holidays are almost here! This is a time when people want to be with family, celebrating! Whether that’s through large multiple day gatherings in your home, or short parties out and about, or even just spending the evenings with those closest to you, one thing is certain, you have a lot on your mind. What presents to get everyone, what food to make, how to get the house cleaned, reminiscing from years past, etc.. Odds are, of all those things on your mind, the one thing that isn’t in your thoughts is your roof.

It’s a common belief that, unless you have a sudden and urgent leak, winter isn’t the time to work on your roof. Generally speaking, this is false. Your roof is such an important part of your home that you should NEVER neglect it, no matter the time of year.

That’s not to say that winter doesn’t bring along some challenges. Rain, Christmas lights, and ice are just a handful that we experience here in the Pacific Northwest.

While heavy rain does cause delays in treatments and large repairs that require opening up the roof, Northwest Roof Maintenance can work with you and the weather, to get things done efficiently on the days that are dry enough for work to be performed.

The thing about ice here in the Vancouver and Portland area is that it doesn’t last long. Just as with rain, we will schedule your job so that both our crews and your roof are safe! Remember your roof is closer to the sun than your driveway, so it’s going to melt and be workable even sometimes when the rest of the world is frozen!

Christmas lights are another common issue during the holiday season. Most repairs can still be done even with Christmas lights on your roof, though they might interfere with cleanings. That doesn’t mean you can’t get ready though. Even with Christmas lights on your roof our professional consultants can inspect your roof and determine what you need so you can be ready as soon as those Christmas lights come down!

 

Why not just wait until summer?summer

You might be saying “this is great that things can be done in the holiday weather, but why does it need to?” “Can’t you just wait until summer comes and you don’t have to even think about this?” Well, you can, but you shouldn’t.

When a problem goes unaddressed on your roof it can grow from a small problem to a major problem. Moss, for example, can be easily addressed without issue when caught in the beginning stages. Removing it at minimal cost of a treatment. However, if you allow moss to sit and grow for months, especially when it’s wet and cold, it can wear away at the shingles, causing leaks and shortening the life of your roof. A small leak repair, or inadequate attic ventilation, though seemingly minor when first noticed, can expand into a larger repair needed or exponential mold growth. All of these things mean expensive repairs that could have been avoided by maintenance done sooner.

What if I don’t know what I need?

If looking at your roof overwhelms you, you aren’t alone. Roofs are intricate things that have to be done just right to be fully effective. It’s easy to fall under the impression that if your roof isn’t leaking it doesn’t need anything, especially when there is so much more to think about this Holiday season. So don’t stress about it, let a professional like Northwest Roof Maintenance come out and inspect your roof. We will look at the whole roof and help you gain peace of mind so that there is one less thing on your plate. Our friendly and professional consultants will never push unneeded repairs or maintenance, and will only recommend what you and your roof need!

So don’t wait! Contact Northwest Roof Maintenance at 503-740-4808 or 360-910-8938 today so we can help you keep up on your roof, even in this busy holiday season!
