Pressure washing tall houses can be a challenging task, especially when it comes to reaching high areas without using ladders. This comprehensive guide will provide you with the necessary information and technical specifications to efficiently and safely pressure wash tall houses.
Best Approach to Cleaning a Steep, 2-Story Roof
Use the Right Equipment
-
Extension Poles: Using an extension pole with a shooter tip can help reach high areas efficiently. A 72″ wand is recommended for reaching 2nd and 3rd stories, but you can find poles up to 108″ in length for even taller structures. These poles are typically made of lightweight, durable materials like carbon fiber or aluminum to minimize fatigue during use.
-
Specialized Nozzles: Long-range nozzles, such as the Assassin Stainless Steel Shooter Tip Soap Nozzle, can be used to reach high areas without ladders. These nozzles are designed to produce a focused, high-pressure stream that can effectively clean surfaces from a distance. The Assassin nozzle, for example, has a maximum effective range of up to 50 feet, making it ideal for tall houses.
Safety Considerations
-
Avoid Ladders: Ladders can be hazardous, especially when working at heights. Using extension poles or specialized nozzles can minimize the need for ladders, reducing the risk of falls and other accidents.
-
Downstreaming: Downstreaming can be a safer option as it allows you to clean high areas from the ground, reducing the risk of falls. This technique involves using a downstream injector to apply the cleaning solution, followed by a high-pressure rinse from the ground.
Equipment Recommendations
-
Pressure Washer: A 4gpm (gallons per minute) pressure washer is sufficient for most cleaning tasks, but higher GPM machines (up to 8gpm) can be used for larger areas or more stubborn dirt. The higher the GPM, the more volume of water the machine can deliver, which can be more effective for cleaning tall surfaces.
-
Soap and Chemicals: Using the right soap and chemicals is crucial for effective cleaning. High-pressure is not always necessary; volume and GPM are more important. Look for concentrated, biodegradable cleaners that can be diluted and applied using a downstream injector or a low-pressure setting.
Safety Precautions
-
Wind Conditions: Be cautious of windy days, as they can make it difficult to clean high areas efficiently and can also increase the risk of overspray or mist affecting nearby areas or people.
-
Proper Training: Ensure you have proper training and experience before attempting to clean tall houses. Pressure washing at heights requires specialized knowledge and skills to ensure safety and effectiveness.
Technical Specifications
- Pressure Washer: 4gpm or higher, depending on the size of the area to be cleaned. For larger homes or more stubborn dirt, consider a 6-8gpm machine.
- Extension Poles: 72″ or longer for reaching high areas, with some poles available up to 108″ in length.
- Specialized Nozzles: Long-range nozzles like the Assassin Stainless Steel Shooter Tip Soap Nozzle, with a maximum effective range of up to 50 feet.
- Soap and Chemicals: Use appropriate, concentrated, and biodegradable soap and chemicals for the type of dirt and surface being cleaned. Dilute as per the manufacturer’s instructions for optimal performance.
