TL;DR: Pennsylvania’s humid climate creates the perfect conditions for roof mold, especially around skylights. Regular skylight cleaning removes dirt, algae, and debris that hold moisture, protecting your roof’s longevity while keeping your home bright and beautiful.
Introduction
Pennsylvania summers are hot, sticky, and packed with humidity—prime conditions for mold growth on your roof. While many homeowners focus on gutter cleaning or siding maintenance, one feature often gets overlooked: the skylight.
Skylights can be a hidden source of roof mold if they’re not cleaned regularly. Here’s why skylight cleaning is more than just a cosmetic upgrade—it’s essential maintenance for your home in humid PA weather.
1. Skylights Can Trap Moisture
Even though skylights are sealed, dirt and pollen form a thin layer that traps condensation. When moisture lingers—especially in a humid Pennsylvania summer—it can lead to mold on the skylight frame and the surrounding shingles.
2. Mold Feeds on Organic Debris
Leaves, twigs, and algae that gather around skylights keep moisture locked in. This creates a breeding ground for mold spores, which can spread quickly to nearby shingles and roof structures.
3. Heat Retention Can Make It Worse
A dirty skylight blocks sunlight while trapping extra heat underneath. That combination of warmth and humidity is ideal for mold growth. A clean skylight lets in more light and helps regulate attic temperatures.
4. Mold Damages Roof Materials
Roof mold isn’t just ugly—it can weaken shingles, flashing, and sealants over time. Once that happens, you’re looking at potential leaks and expensive repairs. Keeping skylights clean helps protect the surrounding roofing materials.
5. Why Professional Cleaning Makes Sense
Cleaning a skylight yourself can be risky and may scratch or damage the glass if done incorrectly. Professional cleaning services use the right equipment, eco-friendly cleaners, and safety techniques to ensure your skylight and roof stay in great condition.
The Smart Move: Pair Skylight & Gutter Cleaning
Moisture control is the best defense against mold. By scheduling skylight cleaning alongside gutter cleaning, you’re addressing two major sources of roof mold at once. Clean gutters keep water flowing away from your roof, while clean skylights prevent localized moisture buildup.
