How to Protect Your Roof from Algae and Moss in Humid Savannah Weather

Living in Savannah, Georgia, means dealing with hot, humid conditions for much of the year. While the coastal charm is unbeatable, the weather can take a serious toll on your roof. One of the most common problems for homeowners in the area is algae and moss growth on roofs — especially on asphalt shingles. If you’ve noticed dark streaks or green patches, it might be time to act before your roof suffers lasting damage.

Why Algae and Moss Love Savannah Roofs

Savannah’s humid climate creates the perfect breeding ground for roof algae, also known as Gloeocapsa magma. This black or dark green streaking usually shows up on the north-facing side of the roof, where moisture tends to linger. If left untreated, it can weaken your shingles and lead to premature roof aging.

Moss growth on roofs is another major concern in the Savannah area. Moss holds moisture against the roof surface, which can cause shingles to curl or lift — increasing the risk of leaks. In some cases, it can even lead to rot on the roof decking below.

How Algae and Moss Damage Your Roof

Both algae and moss may seem like cosmetic issues at first, but over time, they cause serious structural damage:

• Reduced shingle lifespan

• Clogged gutters and poor drainage

• Increased energy bills due to reduced roof reflectivity

• Potential water leaks and wood rot beneath the roof surface

If you're seeing these signs, you should consider a roof inspection in Savannah GA before the damage spreads.

Tips for Preventing Roof Algae and Moss in Savannah

Preventing algae and moss buildup on your roof is possible with a few smart strategies tailored to Savannah’s humid climate:

1. Trim Overhanging Trees – More shade equals more moisture. Cutting back tree limbs allows sunlight to dry out the roof.

2. Clean Your Gutters Regularly – Overflowing gutters create moisture backups that fuel algae and moss growth.

3. Install Algae-Resistant Shingles – If you're replacing your roof, ask about algae-resistant shingles specifically designed for areas like Savannah GA.

4. Add Zinc or Copper Strips – These metals naturally inhibit algae and moss. Installed near the roof ridge, they release particles that help prevent growth.

5. Schedule Routine Roof Maintenance – An annual inspection and cleaning from a professional roofer in Savannah can keep these problems at bay.

Avoid DIY Mistakes

It may be tempting to power wash your roof, but that can cause more harm than good. High-pressure washing can loosen or damage shingles. Instead, hire a roof cleaning company in Savannah GA that uses low-pressure, chemical-safe methods to remove algae and moss.
