3 Reasons Why You Should Never Power Wash Your Shingle Roof

Everyone wants a clean home and that also means a clean roof. Whether you’re doing it for the health of your roof, for aesthetic purposes, or for both, be sure that you are using the proper equipment so that you don’t end up damaging your roof.

The worst thing you can use to clean your roof is a power washer as it is far too strong and aggressive for shingle roofs. Here are the 3 main reasons why you should not use a power washer to clean your shingle roof.

It Is Too Aggressive For A Shingle Roof

Power washers are extremely harsh and powerful. Although it will leave your roof shiny and free from all dirt, debris and mold, a power washer will also strip your shingles of the granules that protect your home from the rain, wind and sun. This will reduce your roof’s lifespan and will force you to have to get your roof replaced earlier. In addition, the strength of a power washer may also cause your shingles to break, crack, or fly off, which will also lead to expensive repairs.

May Lose Out on Your Warranty

Most roof warranties do not cover damages done by the use of a power washer. Any damage done to your shingle roof through a high-pressure tool will probably be your own cost to fix as warranties do not want to cover self-inflicted damages.

Many Parts May Be Damaged in The Process

Shingles aren’t the only things that can get damaged with a power washer. In fact, there are many different parts of your roof that can get extremely damaged including your gutters, the bonding between your shingles and the roof, and more.
