Why High Pressure Washing Is Bad For Your Roof

Does the roof on your home have a bad stain on it? If you're looking to remove the eyesore from your home, but don't want to pay someone who offers residential roofing services to do it for you, you may be able to find the supplies you need at your local home improvement store. But use caution if you want to avoid additional damage to your roof. High pressure washers may sound like just the trick you need to blast away that unwanted moss or gunk, but chances are it will do more harm than good. Here are just a few reasons why you should avoid high pressure washers when cleaning your roof.

High Pressure Cleaning Lets Algae Grow Back

If you have a ton of algae on your roof, you need to treat it by getting down to the root of the problem. Literally. A high pressure washer may blast away the algae you can see, but it won't treat the source of the problem. If algae is growing on your roof, there is likely an infestation under the shingles. High pressure washers can obliterate the algae on the surface but the roots may manage to survive. Algae should be treated with special chemicals or with the help of a professional.

High Pressure Can Cause Physical Damage

Shingles are designed to be durable, but they are not built to withstand a ton of pinpointed pressure. Using a high pressure washer on your roof can actually cause significant damage to your shingles, or cause a shingle that was already on its last legs to break clean off. Then you're going to need to call a roof repair contractor out to your house anyway. Stick to low pressure cleaning methods or just hire a roof cleaning service so you don't end up creating a new problem while trying to fix the first one.

Voids Your Warranty

Most roofs have warranties that can last for decades. But read the fine print. If your roof is damaged during a storm, it will likely be inspected by someone from the insurance company before your claim is fulfilled. If it is obvious that you used a high power washer on your roof (and yes, they can tell), this may void your warranty and your larger repair will not be covered.

Always stick to eco-friendly, low pressure options when cleaning your roof. High pressure can damage your shingles, void your warranty, and may not truly resolve problems like algae anyway.
