Is It Safe to Pressure Wash in Winter?

Sub Headline Optional

Pressure washing in the winter months comes with a range of risks and dangers that every homeowner should be aware of. During this time of year, temperatures dip and the cold weather can have a serious impact on the chemicals used in pressure washing. High-pressure water combined with cold weather can result in broken pipes, ice dams, and other hazardous conditions that can put homeowners at risk.

Pressure washing is not recommended during cold weather, especially if you are not a professional. The combination of cold temperatures and high-pressure water can result in frozen pipes and other hazardous conditions. This can create issues such as ice dams which can cause extensive damage to a home's roof, gutters, and shingles. Furthermore, homeowners can suffer from hypothermia due to prolonged exposure to freezing temperatures while performing the task.

The risks of frozen pipes are particularly concerning since they can create a costly mess that can require professional plumbing services to fix. It is therefore essential for homeowners to keep an eye on their outdoor plumbing during the colder months. Additionally, exposure to freezing temperatures can cause skin irritation, numbness and even frostbite if left unchecked.

Finally, the consequences of ice dams should also be taken into consideration when pressure washing during winter months. Ice dams form when the snow melts on a roof and then refreezes. This causes water to pool on the roof and eventually back up underneath the shingles. Not only can this lead to damage to the roof structure, but it can also create problems inside the house such as flooding or water damage.


If you choose to pressure wash during winter, it is essential to be mindful of the potential risks involved. If at all possible, hold off on pressure washing until Spring. If it can’t wait, the safest option is to hire a professional.
