"I recently bought a house only to find out that I was in need of a full roof replacement and let me tell you what Frank, Johnny and the guys at Valdez construction were incredible. They were great with communicating what needed to be done and why. They were very fair with their pricing and were even able to finish the job ahead of schedule. And now my new house really feels new. Their work looks amazing! I've now got the best looking house on the block. Do yourself a favor and hire these guys!!!"

Roof Cleaning FAQs, answered by experts

It may require stronger cleansers or chemicals, higher-pressure spray, or scrubbing to completely remove algae from a metal roof. Start with a mild cleanser; if that doesn’t work and you're comfortable doing so, use a stronger mix of ⅓ cup of laundry detergent, 1 quart of bleach, and 3 quarts of water to gently scrub the algae with a soft-bristled brush. If algae is present across large portions of your roof, doesn’t come off with gentle scrubbing and cleansers, or is in hard-to-reach areas, this may be a job better left to a pro.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.

Yes, cleaning removes harmful elements that contribute to rot or degradation, extending the roof's lifespan and averting costly future repairs.

Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.

It is not advisable to DIY a roof cleaning job. Cleaning your roof yourself could lead to hazardous falls, scrapes, and even burns, making this a dangerous project. Additionally, using the wrong cleaning solution or cleaning method on your roof could risk damaging it. While some markets offer a DIY roof cleaning kit, these products often speed up the deterioration of your roof.

To ensure that you and your roof are protected, it’s best to leave roof cleaning to a professional with the right chemicals, tools, and equipment to complete the job safely.
