Another surface that you shouldn't pressure wash is lead paint. Lead paint should not be pressure washed, as it can damage, crack and peel paint, sending particles into the air and the surrounding area.
Lead paint is highly toxic and dangerous; it should be avoided whenever possible and these surfaces should not be pressure washed. Worn brick walls and old mortar can be damaged if pressure washed, as they can peel off granules and any other loose material and further damage the surface.

But a pressure washer isn't the right tool for every job and it's easy to get carried away. Composite boards from brands such as TimberTech and Trex often resist deep stains and are well cleaned with a light scrub, followed by rinsing with a garden hose. But if that's not enough, check the warranty terms to make sure power washing doesn't void it. Boards made from South American hardwoods, such as ipe, cumaru and tiger wood, will withstand a pressure wash well.
Those that are made of pressure treated wood, usually southern yellow pine, a soft wood, are also fine, assuming you don't hold the nozzle too close. Consult the owner's manual to confirm which nozzle and configuration the manufacturer recommends for the cover and how far away from the surface it should be kept. Generally speaking, it's best to start with a low pressure nozzle in an unobtrusive location to ensure that the spray doesn't etch or mark the wood. Once you find the correct nozzle, fit and distance, work along the board, following the grain of the wood.

Wood clapboard cladding can also be effectively washed, but if your house was built before 1978, first have a lead remediation specialist test the exterior paint licensed by the Environmental Protection Agency.

Whatever material is pressure washed, be sure to prevent water from getting trapped between the lining and the lining of the house, as moisture promotes mold. Repair or replace loose, damaged, or missing coating, and take special care not to spray water directly into the gaps around doors, windows, or under the overlap joints of the liners. Do not pressure wash the shingle lining, as pressure may release them. If your pressure washer comes with a red 0-degree nozzle, discard this nozzle.
The next size, a 15-degree nozzle, will be used for detailed work, such as removing moss from grooves between pavers. And always wear hearing protection, safety glasses, and protective footwear and gloves while working. We measure how long it takes each pressure washer to remove paint from painted plastic panels.

Do you like having the shingles in place on the roof, unlike your neighbor's patio? Do you want to jump off a ladder, like one of those specialists in water jet packs? Then you should definitely not carry the pressure washer to the ceiling.
A catastrophe of damage and disorder about to occur, pressure washing the ceiling is a dangerous idea that should never be attempted. Unless you want to see your shingles shooting from the ceiling like lethal frisbees, it's much better to avoid the high-pressure power of a pressure washer. Instead, you should use a sprayer with a pump and a scrubber (if necessary) to remove any buildup of moss, algae, or discoloration on the ceiling. .
