Your roof is your home’s first line of defense—and in the hot Highlands Ranch summer, it’s taking a beating from intense sun, heat, and airborne debris. While pressure washing your siding or driveway is common, many homeowners forget one of the most critical maintenance steps: cleaning your roof.
Done right, roof cleaning doesn’t just make your home look better. It also protects your shingles from heat damage, improves your home’s energy efficiency, and can even extend the life of your roof by years. Below, we’ll explain how soft washing works, how it combats harmful growths like algae, and why a clean roof equals lower long-term costs.

What Is the Difference Between Soft Washing and Pressure Washing a Roof?
If you’ve ever seen streaks or stains on your roof, your first instinct might be to hit it with a pressure washer. Don’t.
High-pressure washing can strip off protective granules, loosen shingles, and even punch holes in delicate roofing materials. That’s why soft washing is the professional’s method of choice.
Soft Washing:
- Uses low-pressure water combined with eco-friendly cleaning solutions
- Gently removes mold, algae, dirt, and lichen
- Safe for asphalt shingles, cedar shakes, and tile roofs
- Gets into cracks and crevices without damage
Pressure Washing:
- Uses high PSI (pounds per square inch) to blast away dirt
- Great for concrete, brick, and hard surfaces
- Not recommended for most roofing materials
“Can you pressure wash a roof?”
Technically, yes—but soft washing is safer and more effective for protecting your shingles and roof structure.

Can Roof Cleaning Remove Harmful Algae and Lichen?
Yes, and that’s one of the top reasons to clean your roof—especially during summer, when heat and humidity encourage rapid growth.
What grows on your roof:
- Algae: Appears as dark streaks and feeds on shingle material
- Lichen: A mix of algae and fungus that forms rough, crusty patches
- Moss: Holds moisture against shingles, accelerating decay
Why it’s dangerous:
- These organisms trap moisture, softening shingles and speeding up rot
- They lift shingle edges, letting in wind and water
- Left unchecked, they can cause premature roof failure
Soft washing uses specially formulated solutions (often biodegradable) to kill these growths at the root, preventing regrowth and protecting your investment.
You’ll also protect your gutters from clogs and buildup caused by decaying debris and moss runoff.
Does Roof Cleaning Improve Energy Efficiency in Summer?
It sure does—especially here in sun-soaked Highlands Ranch.
Here’s how a clean roof helps cool your home:
- Removes dark streaks and grime that absorb and retain heat
- Restores reflective properties of light-colored shingles
- Improves attic ventilation by clearing blocked vents and soffits
- Prevents extra strain on your A/C, which lowers energy bills
Dirty or algae-covered shingles act like a dark thermal blanket on your roof. By cleaning your roof, you reduce heat absorption—and that means a cooler interior and more manageable energy costs.
“Does roof cleaning help with cooling?”
Yes. A clean, reflective roof reduces heat absorption, which can improve indoor comfort and lower utility bills.
Roof Cleaning = Long-Term Cost Savings
While roof cleaning might seem like a cosmetic job, it actually protects one of the most expensive parts of your home.
Here’s what regular soft washing can help you avoid:
- Early roof replacement (which can cost $10,000+)
- Water damage from rotted shingles or hidden leaks
- Mold growth in attic or insulation from trapped moisture
- Insurance claims denied due to lack of maintenance
Think of soft washing as preventative care—a small, affordable investment now that can prevent major financial headaches later.
The math is simple, it saves you money to clean now:
- Roof soft wash: $300–$600
- New roof: $8,000–$15,000
- Water damage repair: $2,000–$5,000
