When it comes to maintaining your roof, especially if you own a TPO or metal roof, the cleaning method you choose can make all the difference. Traditional pressure washing might seem like a quick fix, but it can cause damage to delicate roofing materials. That’s where soft roof cleaning methods come in. These techniques are designed to preserve your roof’s integrity while effectively removing dirt, algae, and other contaminants.


Our company isn’t just about cleaning roofs; we have a solid background in roofing installation, including TPO and metal roofs. This means we understand the roof systems inside and out. We clean to preserve, not just to make things look pretty. Let’s dive into why soft roof cleaning methods are the smart choice for your home or property.


What Are Soft Roof Cleaning Methods?


Soft roof cleaning methods use low-pressure water combined with specialized cleaning solutions to gently remove dirt, algae, moss, and other buildup from your roof. Unlike high-pressure washing, which can strip away granules or damage roofing membranes, soft washing is designed to be safe and effective.


Here’s what makes soft roof cleaning methods stand out:


  • Low Pressure: Typically under 500 psi, which is gentle enough to avoid damage.

  • Eco-Friendly Solutions: Biodegradable cleaning agents that break down organic matter without harming your roof or landscaping.

  • Long-Lasting Results: The cleaning solutions kill algae and moss at the root, preventing quick regrowth.

  • Versatility: Works well on TPO, metal, asphalt shingles, and other roofing materials.


For TPO roofs, which are popular for their durability and energy efficiency, soft washing is especially important. High-pressure washing can puncture or degrade the membrane, leading to costly repairs. Soft washing preserves the roof’s protective layer while keeping it clean.

Why Soft Roof Cleaning Methods Are Ideal for TPO Roofs


TPO (Thermoplastic Olefin) roofs are a favorite for commercial and residential properties due to their reflective properties and resistance to UV rays. However, they require special care to maintain their performance and lifespan.


Here’s why soft roof cleaning methods are the best fit for TPO roofs:


  1. Preserves Roof Integrity: TPO membranes can be sensitive to harsh chemicals and high pressure. Soft washing uses gentle cleaning agents and low pressure to avoid damage.

  2. Prevents Algae and Mold Growth: TPO roofs can develop algae and mold, and more importantly oxidagtion which not only look unsightly but can also degrade the material over time. Soft washing kills these organisms at the root, and our propietary process even removes oxidation.

  3. Extends Roof Lifespan: Regular soft washing removes harmful buildup that can cause premature aging or deterioration.

  4. Energy Efficiency: A clean TPO roof reflects sunlight better, helping to keep your property cooler and reduce energy bills.

  5. Cost-Effective Maintenance: Soft washing is a preventative measure that can save you money by avoiding expensive repairs or early roof replacement.


If you want your TPO roof to stay in top shape, soft washing is the way to go. It’s a maintenance step that pays off in the long run.

Do You Rinse the Roof After Soft Washing?


A common question about soft roof cleaning methods is whether rinsing the roof after treatment is necessary. The answer depends on the cleaning solution used and the condition of your roof.


  • Rinsing is often recommended to remove any residual cleaning agents and loosened debris. This helps prevent streaking and ensures the roof surface is clean.

  • However, some soft washing solutions are designed to be left on the roof to continue working over time, breaking down organic matter and preventing regrowth.

  • For TPO roofs, a gentle rinse with low-pressure water is usually part of the process to avoid any chemical buildup that could affect the membrane.


Our approach is tailored to your roof’s needs. We assess the condition and type of roof before deciding on rinsing. This ensures the best results without compromising the roof’s integrity.

How Soft Washing Roof Cleaning Preserves Your Investment


Your roof is a significant investment, and maintaining it properly can save you thousands of dollars over time. Soft washing roof cleaning is not just about aesthetics; it’s about preservation.


Here’s how soft washing helps protect your roof investment:


  • Prevents Damage: High-pressure washing can cause granule loss on shingles or puncture membranes on TPO and metal roofs. Soft washing avoids this risk.

  • Stops Mold and Algae: These organisms can eat away at roofing materials, leading to leaks and structural damage.

  • Maintains Warranty: Many roofing manufacturers require proper maintenance to keep warranties valid. Soft washing is often the recommended cleaning method.

  • Improves Curb Appeal: A clean roof enhances your property’s appearance and value.

  • Saves Money: Regular soft washing reduces the need for costly repairs or premature roof replacement.

Tips for Maintaining Your Roof Between Soft Washes


Keeping your roof in good shape between professional cleanings is easier than you might think. Here are some practical tips:


  1. Trim Overhanging Branches: Leaves and branches can drop debris and shade your roof, encouraging moss and algae growth.

  2. Clean Gutters Regularly: Clogged gutters can cause water to back up and damage your roof edges.

  3. Inspect Your Roof: Look for signs of damage, algae, or moss buildup and address issues early.

  4. Avoid Walking on Your Roof: This can cause damage if you don't know where to be and where not to be, especially on TPO and metal roofs.

  5. Schedule Regular Soft Washes: Depending on your environment, a soft wash every 1-2 years on TPO and 2 to 4 years on metal keeps your roof in top condition.


By following these tips, you can extend the life of your roof and keep it looking great.
