As summer wraps up in Franklin, TN, many homeowners start preparing for cooler weather. But before you pull out the fall decor or clean the gutters, there’s one essential task that often gets overlooked — roof cleaning. August is the perfect time to address roof issues before falling leaves and autumn rains make them worse.
At Wildcat Cleaning & Pressure Washing, we’ve seen it time and time again: waiting too long to clean your roof leads to hidden damage, costly repairs, and even premature roof replacement. Let’s break down why late summer is the ideal time to tackle roof cleaning — and how doing it now prevents big problems later.

1. Remove Moss and Algae Before Fall Leaves Cover It Up
Roof stains aren’t just ugly — they’re a warning sign. That green and black discoloration on your roof is usually caused by:
- Moss, which traps moisture and damages shingles
- Algae, which feeds on limestone in asphalt shingles and weakens them
- Lichen, a hybrid of fungi and algae that clings stubbornly to surfaces
August gives you dry, stable weather to tackle these growths before:
- Falling leaves bury and trap moisture, worsening the growth
- Wet debris hides moss from view until it’s already damaging your roof
- Mold spores spread into gutters, soffits, and even attic spaces
“Can moss damage my roof?” Yes — moss holds moisture against the shingles, which can cause them to lift, crack, or rot. Left untreated, it shortens the life of your roof.
Wildcat uses a safe soft-wash roof cleaning process to kill and remove moss, algae, and lichen without damaging your shingles.

2. Prevent Premature Aging of Shingles
UV rays, heat, rain, and organic buildup wear on your roof all year long. But when moss and algae are left untreated, they act like a sponge — holding moisture and creating a breeding ground for decay.
What happens when you skip seasonal roof cleaning?
- Shingles become brittle and curl at the edges
- Granules wear away, reducing protection from UV rays
- Dark streaks absorb heat, raising attic temperatures and energy bills
Roofs with black algae streaks can get up to 10–15°F hotter, forcing your HVAC system to work harder.
Cleaning your roof every 1–2 years keeps shingles in peak condition and extends your roof’s lifespan by years — potentially saving you thousands in early replacement costs.
3. Reduce Risk of Water Intrusion During Autumn Storms
Franklin’s fall weather often brings heavy rains and high winds. If your roof is already compromised by moss, loose shingles, or clogged valleys, the risk of water damage rises fast.
Why roof cleaning in August matters:
- Ensures shingle edges are sealed and clear of debris
- Keeps roof valleys and channels clean so water can flow properly
- Prevents soft spots that lead to leaks in attics and ceilings
“Can a dirty roof cause leaks?” Yes — moss and clogged debris prevent water from draining correctly, which can lead to standing water, saturated shingles, and leaks.
Before storm season hits, give your roof a clean slate. Trust Wildcat to clean it thoroughly and safely so it’s ready to take on autumn storms.
4. August Offers the Ideal Conditions for Roof Cleaning
Timing is everything. Here’s why August is your window of opportunity:
- Dry, warm weather helps cleaning agents work more effectively
- Low humidity reduces drying time and mold regrowth
- Cleaning now prevents fall cleanup delays when leaves and rain increase
Roof cleaning also improves your home’s curb appeal just in time for back-to-school routines, fall parties, and holiday visitors.
