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.

Top notch contractor. I expected high prices because of the stellar reviews but the cost to clean my gutters was spot on reasonable. I emailed for a quote late in the evening and the owner responded within 30 min (at 11:30 pm). He sent a full estimate PDF quote within 24 hours that included a copy of his NJ contractors license, insurance, before and after pics and itemized estimate. The job was done within 3 business days of accepting the estimate. I received before and after photos of my gutters to show the work was one (because to be honest unless you get up on the roof it’s a blind service), and option to pay invoice electronically with a credit card. Do not hesitate to use this company. You’ll rest better knowing you are in good hands.
