Expert Answer

Not exactly, but it can deal some damage. To avoid problems, move your patio furniture and other items away from the house. Then, seal windows and doors, adding towels under anything that you think might leak.

Question

What is the best time of year to pressure wash my home?

Community Answer

Summer as the water will dry quickly. This will also prevent any lingering water from freezing and possibly damaging your home.

Question

Should I plug the power washer into an electrical outlet?

Yes, you should. You may need to use an extension cord though, just so you can reach everywhere that you need to reach.

Question

Is it okay to pressure wash a tile roof?

Community Answer

You can do this, but definitely be aware of the fact that the force may knock a few tiles loose. This isn't something that I would recommend as a long term solution seeing as to how the costs may start to add up over time.

Question

Do you have to have an attachment at the faucet to protect it from pressure?

Community Answer

To protect the pressure washer, most pressure washers are good with water pressures from 10-110 psi, so no need to protect the pressure washers inlet. It has to be pressurized water, not from a large tank on a truck or you need to pump from the tank to the washer inlet.
