If you live in Bear or Glasgow — zip codes 19701 and the surrounding neighborhoods off Route 40, Peoples Plaza, and the communities along Wrangle Hill Road — you have probably noticed those dark stains running down your roof shingles. They are not dirt and they are not just an eyesore. That black discoloration is Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. Left alone, it shortens the life of your roof by years and can quietly void manufacturer warranties. True Blue Pro Wash specializes in roof soft washing that kills the organism at the root, not just masks it, so your roof in Bear or Glasgow stays cleaner longer.
New Castle County's climate is tough on rooftops. Humid summers, heavy spring pollen, and freeze-thaw cycles from November through March create the exact conditions that allow Gloeocapsa magma and green algae to spread fast. North-facing roof pitches in neighborhoods like Cameron Hills, Beckett's Ridge, and Brennan Estates rarely get enough direct sun to dry out between rain events. That shade plus moisture equals a perfect breeding ground for the streaks and green haze that homeowners in 19701 call us about every season.
Why Soft Washing — Not Pressure Washing — Is the Right Call for Your Roof
A standard pressure washer running at high PSI will blow granules off asphalt shingles, crack older tiles, and force water under flashing. That kind of damage can lead to leaks and will definitely invalidate most shingle warranties. Roof soft washing uses a low-pressure rinse — typically under 100 PSI at the surface — combined with a professional-grade, biodegradable cleaning solution that kills mold, algae, lichen, and bacteria on contact. True Blue Pro Wash follows ARMA-recommended guidelines for roof cleaning, which means we treat your Bear or Glasgow roof the way the shingle manufacturers intend it to be treated.
What the Roof Soft Washing Process Looks Like in Bear and Glasgow
When we arrive at your home — whether you are in the Wrangle Hill area, off Old Baltimore Pike, or in one of the newer developments closer to the Glasgow Park commercial corridor — we start with a full visual inspection of the roof. We check for loose flashing, cracked cap shingles, and any areas where excess moisture might already be causing damage. Then we pre-wet your landscaping and any hardscaping below the roofline to protect plants and pavement from chemical runoff.
Next, we apply our cleaning solution from the ridge down, letting it dwell long enough to neutralize the algae and loosen any lichen or moss. A low-pressure rinse clears the dead organisms away. In most cases the difference is visible the same day, and it keeps improving over the following two to three weeks as rain washes off the final residue. We finish by rinsing your gutters and downspouts so no residue backs up into your gutter system.

How Long Will a Roof Soft Wash Last in New Castle County?
Most homeowners in Bear and Glasgow see three to five years of results after a professional soft wash — sometimes longer on south-facing pitches that get consistent sun exposure. The algae-inhibiting agents in our solution keep working after the visit, and Delaware's seasonal rains help rinse off dying organisms over time. If you have mature trees close to the roofline, or if your home sits in a low-lying area that stays damp longer after storms, you might be on a three-year schedule rather than a five-year one. Either way, routine soft washing costs a fraction of an early shingle replacement and protects the investment you have already made in your home.

Frequently Asked Questions
Is soft washing safe for the asphalt shingles on homes in Bear and Glasgow?
Yes. Roof soft washing uses low pressure — well under 100 PSI at the surface — combined with a biodegradable cleaning solution. This is the method recommended by the Asphalt Roofing Manufacturers Association (ARMA) and will not strip granules or damage shingles the way high-pressure washing would. It also does not void manufacturer warranties, which high-pressure cleaning often does.
How long does a roof soft wash take on a typical Bear, DE home?
Most single-family homes in the Bear and Glasgow area take two to four hours from setup to cleanup. Larger homes, steeper pitches, or heavy lichen growth can add time. We will give you an accurate time estimate when we provide your free quote.
Will the cleaning solution harm my landscaping or lawn around my home in 19701?
We pre-wet all plants, shrubs, and lawn areas before applying the cleaning solution and rinse them again afterward. The biodegradable solutions we use are designed to be safe for landscaping when properly diluted and rinsed. We take precautions on every job to protect your property.
How often should a Bear or Glasgow homeowner schedule a roof soft wash?
In New Castle County's humid Mid-Atlantic climate, most homeowners benefit from a professional roof soft wash every three to five years. Homes with heavy tree cover, north-facing roof sections, or significant shade may need cleaning on the shorter end of that range. We can assess your specific situation when we come out for an estimate.
Do you serve all of Bear and Glasgow, or just certain neighborhoods?
True Blue Pro Wash serves all of Bear and Glasgow, including Cameron Hills, Beckett's Ridge, Brennan Estates, the Wrangle Hill corridor, and communities along Old Baltimore Pike and Route 40. If your home is in zip code 19701 or nearby in New Castle County, give us a call at (302) 757-9755 and we will confirm coverage.
Can you clean my roof and gutters on the same visit?
Absolutely. Roof soft washing and gutter cleaning pair naturally — the roof wash can loosen debris that settles into the gutters, so cleaning them the same day makes sense. We also offer gutter brightening to remove the black oxidation streaks on the outside of gutter faces, and we can discuss gutter guard installation if clogging is a recurring problem for your home.
