Your roof is your home’s first line of defense against the elements, and like any part of your house, it requires regular care. Unfortunately, it's often overlooked—until stains or leaks appear. Roof washing is a proactive way to remove algae, moss, and debris that can cause long-term damage if ignored.

Dark streaks on your shingles are often caused by algae, which feeds on limestone granules. Over time, this growth can lead to shingle deterioration and reduce the roof’s lifespan. Moss is another culprit—it traps moisture, which can cause shingles to lift and wood to rot. If left untreated, it may lead to costly repairs or even full roof replacement.

The safest and most effective method for cleaning your roof is soft washing. This involves a biodegradable solution applied with low pressure to kill mold and algae at the root. Avoid using high-pressure washers, which can damage shingles and void warranties.

Ideally, roofs should be inspected and cleaned every 1–2 years. In humid or shaded areas, annual cleaning is even more important. Keeping your roof clean not only extends its life but also enhances the overall look of your home—an important consideration if you're planning to sell.
