Roof Cleaning Mt. Laurel NJ

Mt. Laurel NJ residents have been wondering what is on my roof and why are those stains there? Well the answer is the black roof stains are from an algae called Gleocapsa Magma. What this algae does is it eats the limestone filler loosing up the granules on the shingle. This will cause the shingle to break down faster causing you the homeowner to have to replace your roof sooner. Another culprit to destroying roofs is Moss and Lichen. The moss and lichen will attach to your roofs surface and start to work its way under the tad lifting it up. This can lead to lost shingle tabs during storms and eventually cause a roof leak which could be very costly.

The good news is Diamond roof cleaning has been leading the way for roof cleaning in Mt. Laurel New Jersey. We are always learning and applying the best techniques to our specialty service of roof cleaning. We have recently joined up with a company called soft wash systems based out of Florida.

We have used Diamond Roof Cleaning LLC for the last several years to power wash our house, windows and clean our roof. The service, attention to detail and finish is top notch. We used them for the first time this year to clean our concrete patio and white vinyl fence that had lots of stains from the trees. The job came out exceptional and well beyond my expectations! I would never consider using another company for any of our power washing needs. The owner is super nice and very personable as well as a true professional. Do not hesitate to give them a call.
