This comprehensive guide will walk you through how CA Wash Pros handles power washing a roof, discuss the different types of roofs we service, and highlight our commitment to safety and quality.
Why Power Washing A Roof is Important
Roofs are constantly exposed to the elements, making them susceptible to the buildup of dirt, algae, moss, and other contaminants. power washing a roof regularly helps maintain the structural integrity of your roof, prevents damage, and enhances curb appeal. It’s a proactive measure that can save you from costly repairs down the line.
Our Roof Power Washing Process: Step-by-Step Guide
- Preparation and Safety
- Inspection: Our team conducts a thorough inspection of your roof for any damage or weak spots. This ensures that the pressure washing process doesn’t exacerbate existing issues.
- Protective Gear: Our technicians are equipped with safety gear including gloves, goggles, and non-slip shoes to ensure their safety during the job.
- Weather Check: We choose a calm day with no strong winds to avoid accidents and ensure the effectiveness of the cleaning process.
- Choosing the Right Equipment
- Pressure Washer: We use pressure washers with adjustable settings to cater to different roof types. For roofs, We apply the appropriate PSI (Pressure per Square Inch) to avoid damaging shingles or tiles.”
- Nozzles: Our team uses a wide-angle nozzle (25-40 degrees) to distribute the water pressure evenly and gently.
- Cleaning Solutions
- When it comes to cleaning roofs, we opt for a different approach than eco-friendly solutions. Our method involves using a biocide at a high concentration level. This ensures thorough elimination of contaminants like algae, moss, and lichen, which can compromise the integrity of your roof over time. This potent treatment effectively targets and neutralizes these growths, preventing their recurrence and extending the lifespan of your roof.
- Roof Power Washing Techniques
- Start at the Top: Our technicians begin at the top of the roof and work their way down. This keeps water from penetrating beneath the tiles.
- Gentle Pressure: We apply gentle pressure, holding the nozzle at least 12 inches away from the roof surface. The nozzle is moved in a sweeping motion to cover all areas uniformly.
Different Types of Roofs We Clean
- Asphalt Shingle Roofs
- Method: For asphalt shingle roofs, we avoid using a power washer. Instead, we use a garden hose combined with a garden gun, providing a low pressure of about 60 to 100 psi. This method prevents the degranulation of shingles, preserving the protective granules that shield against sun rays.
- Tip: We meticulously clean each shingle, agitating and removing as much moss as possible. Afterward, we apply a strong biocide across the entire roof to neutralize any remaining moss, even those not visible to the eye.
- Precautions: We also take precautions to protect the surrounding landscape, as the biocide is potent and can harm plants. We advise keeping pets indoors during the process due to their sensitive sense of smell and potential irritation from the biocide.
- Tile Roofs (Clay or Concrete)
- Method: For cement tile roofs, our cleaning method involves power washing. We avoid using biocides as they can be costly and unnecessary. Power washing effectively removes approximately 98% of moss, making biocides redundant for the remaining small percentage. Additionally, after applying biocide it will remain active on the roof for about a week before breaking down under sunlight, which doesn’t justify the extra expense.
- Pigment Loss: A downside of power washing a roof is the potential for pigment loss, especially in colored tiles. If a tile is cracked beyond repair, we will swap it out. Please ensure you have replacement tiles available; if not, we can provide information on where to purchase them. We handle various types of tile roofs, including flat, curved, and smaller curved tiles.
- Clay Tiles: Also known as terracotta, clay tiles are similar to cement tiles in terms of the cleaning process. We typically power wash them. However, due to their delicate nature, clay tiles may require complete replacement if they crack. During cleaning, we ensure minimal pressure on the tiles by using large foam pads to distribute our weight. The approach can vary depending on the specific type of clay tile we’re handling.
- Metal Roofs
- Method: Metal roofs can handle higher pressure compared to other materials. However, we ensure the cleaning solution is non-corrosive to avoid damaging the metal.
- Tip: We rinse thoroughly to prevent streaking and corrosion.
- Wood Shake Roofs
- Method: The final type of roof we clean is a wood shake roof. We approach this by scrubbing each plank with a wood brush. Power washing a roof isn’t ideal for this kind of roof because the pressure can cause the planks, which are often already loose, to come off entirely. Additionally, wet wood shake roofs become extremely slippery, making them hazardous to walk on.
- Biocide Application: After scrubbing, we apply a strong biocide, similar to the treatment used on asphalt shingle roofs. We also take care to protect the surrounding landscape from the biocide’s strong effects.
