Roof power washing isn’t just a home maintenance chore, it helps to preserve the structural integrity of your roof and extend its lifespan. A dirty roof can affect your homes visual appeal and lower its appraised value, but a regular cleaning by professionals can prevent the need for costly repair. If you’re considering renting or purchasing a pressure washer to do your own roof washing, it’s important that you understand how the process works and the risks involved.

Is Roof Power Washing Safe?

Power washing your roof can be tricky and downright dangerous, especially if you’re not experienced with the equipment. A powerful jet of water ejected at high speeds can damage or dislodge shingles and tiles, and can also cause serious injury if it comes into contact with your skin.

A professional roof cleaner uses a low-pressure method of washing known as “soft washing” to eliminate debris and buildup without harming the surface. This technique is especially effective for brittle materials such as asphalt shingles and clay tiles used in Mediterranean style homes.

There are also earth-friendly biodegradable products available that can be combined with a power washer to provide a more thorough clean while still being safe for the environment and your family. Professional roof cleaners will also use a wide range of nozzles to create different water flow patterns, ensuring that the most stubborn dirt and stains are removed from your property.

You may think that it’s cheaper to rent or buy a power washer yourself and save on a professional cleaner, but this could end up costing you more in the long run. You’ll likely have to replace your pressure washer sooner than you would have done if you had hired an Arlington power washing professional in the first place, and you’ll probably have to pay for additional repairs caused by your attempt to power wash the roof yourself.

The standard PSI of a power washer is between 2 and 2.5. This is not enough to damage most shingles and tile, but it can penetrate through old felt and leak into the loft space. A professional roof cleaner will know how to properly assess the condition of your roof and only blast it with water if it’s safe to do so.

A DIY Roof Power Wash is Not a Good Idea

Using a pressure washer to clean your roof can actually shorten the lifespan of your roof and leave it vulnerable to weathering and damage. It’s not uncommon for a homeowner to use a high-pressure jet of water on their roof, only to see it disintegrate within months. Even if you don’t intend to use a high-pressure washer on your roof, it’s best not to use one at all.

If you’re planning to hire a professional roof cleaner to perform a soft wash on your roof, make sure they’ve got the right gear and a wealth of experience in the field. You can always ask for references and check out reviews before hiring someone to complete the job.
