What Are The Advantages And Disadvantages Of Roof Cleaning?

The average roof requires cleaning about once a year. This process not only keeps your home looking great but also preserves your roofing material. Growths like algae, mold, and moss can weaken and erode your roof’s surface, leading to future leaks. Additionally, dirt and debris can obstruct proper drainage around valleys and flashing. This obstruction can cause water to pool on the roof, resulting in damage. Regular cleaning helps maintain the integrity and appearance of your roof.

The main drawback to roof cleaning is the cost, especially for large homes, steep roofs, or multi-story houses. Additionally, overly aggressive cleaning can damage the roof, strip granules from shingles, and crack roof tiles. You also risk voiding your roof’s warranty.

Should You Clean Your Own Roof Or Hire A Professional?

You can clean your roof yourself if you understand the risks and take proper safety precautions. However, it’s a messy and time-consuming job, so many homeowners choose to hire professionals instead. Here’s what you can expect from both options.

Expert Roof Cleaning

Homeowners with steep roofs or multiple stories should hire a professional roof cleaning service. Professionals have better equipment and stronger cleaning products. They know how to complete the job quickly and thoroughly. They also handle specialty problems like salt buildup or algae stains effectively. Ensure any roof cleaner you hire is licensed. Obtain copies of liability and workers’ compensation insurance before signing a contract.

Do It Yourself Roof Cleaning

You can save money on roof cleaning by doing it yourself if you do it correctly. This involves taking appropriate safety measures while working on a roof. Use methods that won’t cause any damage. Renting a pressure washer costs $25–$50 per day. Make sure you know how to use the low-pressure setting. Cleaning solutions and other tools will add another $40–$50 for a 1,500-square-foot roof. Remember, a damp roof is slippery, so take necessary precautions. Roof work is very dangerous, especially for those without prior experience.
