Your roof does more than shield your property—it’s your first line of defense against the elements. But over time, it can become a home for things you don’t want, like moss and algae. While these might initially seem harmless, they can cause severe damage if left untreated.

At Jeff’s Exterior Washing, we understand how important it is to protect your home or business. In this blog, we’ll explore the dangers of moss and algae and how regular roof cleaning services can keep them at bay.

Why Moss and Algae Are More Than Just an Eyesore

It’s easy to think of moss and algae as cosmetic issues, but they do much more than make your roof look dirty. Here’s why they’re more dangerous than you might realize:

  • Constant Moisture Traps: Moss absorbs and holds moisture against your shingles. That dampness sticks around longer than you might think, slowly wearing down your roof over time. This can lead to lifted, cracked, or warped shingles, opening the door to leaks and water damage.
  • Shingle Erosion: Algae, especially those black streaks you might see, will feed on the limestone in your shingles. As they spread, they weaken your roof’s protective layer, preventing it from shielding your home as effectively as it should.
  • Added Weight on Your Roof: Moss doesn’t just sit on your roof—it grows thick and heavy, adding weight your roof wasn’t designed to carry. Over time, this can stress the structure of your roof, leading to more significant, more expensive problems.
  • Blocked Gutters and Drainage Issues: Moss and algae can block your gutters and downspouts, preventing water from properly draining off your roof. This can cause water to back up and damage your roof and your home’s foundation.
  • Reduced Curb Appeal: Let’s face it—moss and algae are not a good look for any home. They can make even a well-maintained house appear old and neglected, lowering your home’s curb appeal and value.

How to Safely Remove Moss and Algae

If you’ve noticed moss or algae growing on your roof, it’s tempting to try and clean it yourself. However, DIY roof cleaning is rarely ideal. Whether it’s a tile roof, roof shingles, or a metal roof, improper roof cleaning can do more harm than good. Here’s how we take care of it at Jeff’s Exterior Washing:

  • Soft Washing: Instead of using high-pressure water that can damage your shingles, we use a gentle soft wash method. Soft washing uses low-pressure water and safe cleaning solutions that break down moss and algae without harming your roof.
  • Eco-Friendly Cleaning Solutions: Our professional cleaning team uses products that are tough on moss and algae but safe for your home and the environment. Our roof washing solutions kill the moss and algae at the root, so they don’t return anytime soon.
  • Professional Expertise: Roof cleaning isn’t just about spraying water and calling it a day. Our experienced soft and power washing team knows how to clean your roof without damaging it. We inspect your roof, choose the correct cleaning method, and ensure every inch of moss and algae is gone.

How to Keep Moss and Algae from Coming Back

Once your roof is clean, the last thing you want is for the moss and algae to return. Here are a few simple ways to prevent future growth following a roof wash service:

  • Trim Back Tree Branches: Moss and algae thrive in shady, damp areas. Trimming any branches from overhanging trees will let in more sunlight, keeping your roof clean, dry, and less inviting to moss and algae.
  • Clean Your Gutters: Regular gutter cleaning ensures water can flow freely off your roof, reducing the risk of moisture buildup that attracts moss.
  • Add Zinc or Copper Strips: Installing zinc or copper strips along your roof’s ridge can help prevent moss and algae from forming. When it rains, these metals release ions that kill moss and algae.
  • Schedule Regular Roof Cleaning: Keeping up with a routine roof cleaning service is the best way to keep moss and algae at bay. At Jeff’s Exterior Washing, we recommend periodic cleanings to ensure your roof stays in top shape year-round.
