Roof Cleaning Cost & Price Guide

Whatever material your roof is made of, it should be designed to last upwards of 20 years. As a homeowner, you should make the extra effort to ensure that your roof surpasses its estimated lifespan by cleaning and maintaining it over time. While many people choose to rent a pressure washer and tackle the job on their own, it can be a time-consuming and potentially risky job. In most cases, it is best to hire a professional roof cleaner who has experience and can complete the project safely.

Average Cost of Professional Roof Cleaning

Unless you live in an unusual climate or have an incredibly large home, there is a good chance that the cost of professionally cleaning your roof will fall within the national average range of $391 to $517. While there is no guarantee that your geographic area will fall exactly in that span, most homeowners report an average amount of $454, which is almost directly in the middle.

Reasons To Clean Your Roof

If you aren't sure whether cleaning your roof is a necessity, it is important to fully understand the benefits. On an aesthetic level, a clean roof simply looks better. If you are trying to increase the curb appeal of your home, this is one option that is relatively cost-effective and can give the entire structure a fresh look if you are trying to sell your home. A clean roof can also increase the energy efficiency inside the building, which may play a role in lowering your total energy bills each month.

How a Roof Gets Professionally Cleaned

It might surprise you to learn that even on a pitched roof, professionals use heavy-duty machinery to remove the moss, algae and debris that can build up on the surface or between shingles. Power washing machines and portable pressure washing machines are the most popular way to get a roof clean in a hurry, but many professionals may also use a handheld brush with a cleaning solution in order to tackle stubborn stains or especially problematic areas. If you have a copper roof, professionals may even use a basic cleaning solution of lemon juice and salt to restore shine. 

What Influences The Total Cost of Professional Roof Cleaning

There are a number of things that can affect the total price of your professional roof cleaning. The height and pitch of a roof can increase the overall cost if professionals require extra equipment for security. If your home is shaded by large trees, there may be more leaves and moss than normal because of the lack of direct sunlight. In addition, coastal homes may be more damaged by salt than you realize, and this can make cleaning the roof harder for professionals.
