Roof Cleaning 101: Why You Need to Get Rid of Black Streaks

Have you noticed black streaks on your roofing? These can have a very significant impact on your home’s curb appeal. However, that’s not the worst problem they can cause. If left unaddressed, those black streaks can spread, eventually damaging your roofing.

These are just two reasons you need to get rid of black streaks on your roof as soon as you spot them. Just understand this is not a DIY job. Instead, you need to hire roof cleaning professionals.

At Diamond Roof Cleaning, serving homeowners in and around Medford, NJ, our experts are equipped with the tools, knowledge, and experience necessary to remove black streaks on your roof efficiently and thoroughly. If you’ve noticed black streaks on your roof, get in touch with us sooner rather than later to avoid future headaches.

Why You Should Contact Roof Cleaning Pros to Remove Black Streaks on Your Roof

Many homeowners who spot black streaks on their roofs don’t necessarily know what those black streaks actually are.

Black streaks on roofing are almost always a telltale sign that Gloeocapsa magma (better known as roof algae) has begun to accumulate.

Again, roof algae isn’t just unsightly. This organism can spread if it isn’t cleaned away. Over time, it will begin eating away at your shingles.

The consequences of this can result in hefty bills you might not be prepared to pay. Naturally, if your roofing is damaged, you’ll have to replace the affected sections earlier than you otherwise might have.

Damaged shingles also prevent your roof from effectively insulating your home. As such, you’ll need to run your heating and cooling equipment more often. Along with putting unnecessary strain on your HVAC system, this will also result in high utility bills.

Damaged roofing will leave your home vulnerable to the elements as well. If water leaks into your home, you may need to address unexpected water damage. Water leaking into a home can also allow mold to accumulate, as mold develops and thrives in moist environments.

You don’t need to face these unwanted challenges if you’re proactive. The sooner you schedule roof cleaning service when you notice black streaks, the greater the odds you’ll prevent major damage.

Again, cleaning black streaks away from your roofing is a job for the professionals. If you try to rinse your roofing down with a garden hose, you won’t thoroughly clean it. On the other hand, if you spray your roofing with a pressure or power washer, you will likely damage it, as most residential shingles can’t take that kind of force. 

This isn’t something you need to worry about when you hire our team at Diamond Roof Cleaning. We use the soft wash method to clean black streaks away from our customers’ roofs. This method involves applying safe eco-friendly detergents along with a gentle rinse of water. The combination of the two thoroughly removes roof algae without causing damage. If you live in the Medford, NJ area and need help getting rid of black streaks on your roof, call us today at (609) 929-5812 to learn more about what we can do for you.

It was tremendous leaving for work and coming home to an amazingly clean home. These photos were taken the same day. My landscaper recommended Mike and he and his team delivered. A quick response and excellent service with quality results. I just had new landscaping in place and he tarped my plants and all debris was removed. I highly recommend!

It was easy to get a quote and schedule the work. They came out and definitely did a great job of cleaning the house. It is the cleanest it ever was. My only issue is that two of the exhaust fan covers were blown off (?) and no one said anything about it before they left. I did not get the covers back so I assume they were taken away. I'm attaching a picture of one of them. If it was at least mentioned, then I would have given a 5 star review. -Changed to 5 Stars- This is a class A company to deal with. The owner came out and inspected the damage and issued a reimbursement. He also offered to do the installation which was more than I expected. They really do care that their customers are 100% satisfied!

This is the second time I’ve used Diamond Roof Cleaning to wash my stuccoed home. I’d heard horror stories from others who’d had their homes power washed and questioned the owner, Mike, who gave me addresses of homes similar to mine so I might see his work. I liked what I saw and took a chance with DRC. They did a fantastic job. The workers were friendly, respectful of my property by removing cushions from the patio chairs to keep from damaging/wetting them and answered any questions I had. Now my house looks brand new and I couldn’t be happier.

Quick response and super easy to schedule the work. They did a fantastic job! The siding looks great! The window trim looks like it did the day it was installed. Came up super white and so clean. Definitely will be using them in the future. Highly recommend !!!

Have a big brick and stucco house with tile roof and paved driveway. Diamond Roof Cleaning did a great job on all- roof, walls and pavers. Price was reasonable. Job was finished on time. Other companies gave higher quotes and then tried to get the job by giving special deal. I like it when there is no need to negotiate as was the case with Diamond Roof Cleaning.
