How Roof Cleaning Works

A roof infested with algae, moss, or other organic life will have a dramatically shortened life if left untreated. On asphalt shingles, the organisms will attach to the protective granules. If the incorrect technique is used (for example, too much pressure or using improper equipment), the shingle granules designed to protect the roof will be removed too.

Our team of experts clean roofs using a low-pressure, soft wash roof cleaning technique that removes moss, mildew, fungi, and dirt but will not damage the roofing material.

Two-Step Roof Cleaning Process

1. Apply Cleaning Solution to the Roof
The cleaning solution we use is 95% water and 5% sodium carbonate. It is chlorine- and acid-free and is safe for people, pets, and plant life.

2. Gently Wash the Roof
A soft, low-pressure and high-volume wash gently removes dirt and algae growth from roof surface with a non-abrasive rover.

Our roof cleaning service is certified by the Roof Cleaning Institute of America.
