It is possible to wash your own roof, but we don’t recommend it. First, getting up on any roof is dangerous without proper safety equipment, especially if wetting a metal roof and making the surface slick. Additionally, it’s easy to damage your roof or force water between roof seams if you use a power washer, which can lead to property damage. Hiring a professional roof cleaner will save you time, keep you safe, and ensure that your roof looks new again without damaging it in the process. Plus, roof cleaning is a relatively affordable home improvement project.

Pressure washing pros use several factors to determine fence pressure washing costs—and one of the main factors they consider is the fence’s material. The material dictates the required PSI—which, in turn, affects the amount of labor needed for the job.

Contractors may also consider the number of gallons per minute (GPM) needed to pressure wash specific materials. GPM, which refers to the rate of water being released from a pressure washer, helps determine how long a job will take for specific fencing materials.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.

Experts agree that spring and fall are the best times to pressure wash a home's exterior due to the milder weather. Aim to schedule the project once a year during a warm, dry season, typically between March and November, depending on your local climate. Many prefer the spring to clean away dirt and grime that has gathered over the winter, preparing the house for the rest of the year. You can always perform touch-ups in the summer or fall as needed.
