The Importance of Roof Cleaning

The Importance of Roof Cleaning

Roof Cleaning Summerville SC is the process of removing algae, mildew, mold, lichen, and moss from roofs and oxidation from metal roofs. This helps extend the lifespan of the roofing materials. Regular roof cleaning improves curb appeal and may help keep home insurance policies valid. If a homeowner neglects to clean their roof regularly, they could have to pay for a full replacement.roofing

The dark streaks on a roof often seen are blue-green algae or moss colonies. They appear on the surface because these primitive plants send spores and thrive in damp areas. The spores can also be carried by wind and animals to other homes, which explains why a whole neighborhood may have moss or algae on its roofs.

While moss isn’t as harmful as mold, it can damage asphalt shingles and make them look old before their time. It can also interfere with the reflective and cool roofing properties of some shingles. If left untreated, moss will eventually eat through the shingle and cause leaks.

A soft wash of a solution containing household-strength chlorine bleach (sodium hypochlorite) and water usually removes the moss. This solution may need to be left on the roof for up to 15 minutes to effectively kill the moss. Then, it can be rinsed off the roof with a hose on a low-pressure setting. Some chemical companies sell roof treatment products that contain fungicides to keep moss and algae from returning after the initial cleaning. Zinc strips near the roof’s peak also reduce regrowth by washing off metal ions that retard moss and algae growth.

Always have a professional inspect the condition of your roof before using any chemical treatment. A roof contractor can explain whether the moss and algae are damaging the shingles and, if necessary, recommend a good cleaning company. Never power-wash a roof; this can lift and dislodge granules, which exposes the shingles to premature UV exposure that weakens and fades them.

Black Streaks

Many homeowners notice black streaks or splotches on their roof and are concerned they may be mold growth or a sign of a leak. However, the unsightly streaks are actually caused by roof algae (Gloeocapsa magma). Roof algae like shade and moisture. They grow and develop a hardened outer layer that gives them their unattractive, dark appearance. They also feed on the limestone filler in asphalt shingles and slowly wear them down. This deterioration can lead to a number of issues, including a weakened roof, wood rot, and mold or mildew on the exterior of your home.

Left unchecked, the black streaks of roof algae can spread to other areas of your roof and to the surrounding shingles of other homes in the neighborhood. The spores are airborne and easily transfer from one roof to another. It is important to avoid trying to remove the stains yourself using caustic chemicals like bleach, which can actually cause more damage to your roof. The best way to get rid of the black streaks is to hire a professional roof cleaner with proper training and industry-standard equipment. They should use a method called “soft washing,” which allows them to apply the treatment to your roof from the safety of the ground without using dangerous chemicals or excessive pressure.

The right roof cleaning treatment will sterilize Gloeocapsa magma and all other organic growths on your roof and kill them. The treatment will also extend the lifespan of your shingles by years, saving you money on roof replacement and home repairs.


If you hire someone to clean your roof, make sure they know how to do it safely. Using ladders improperly or cleaning the wrong areas can damage the surface and strip away granules from shingles. This can cause leaks and premature roof replacements. Keeping up with regular roof cleaning prevents these problems and keeps your warranty valid.

Some cleaning companies use high-pressure washing to remove moss, mildew, algae, bird poop, leaves, and other microorganisms from your roof. This process is damaging to most roofing materials and can void your warranty.

The other main type of roof cleaning is soft washing. This is a gentler approach to removing the same organisms as pressure washing. In soft washing, a professional uses water at less than 1,000 psi and mixes in a detergent or other cleaning agent to target specific organisms. This is a safer approach for most roofs and is recommended by roofing manufacturers.

A dirty roof can attract other pests, too. If critters form nests in your gutters or cling to the undersides of roof tiles, they can easily make their way inside your home. Regular roof cleaning helps keep these invaders at bay and prevents them from causing damage or making your roof their home.

In addition, if you have a lot of stains that are caused by foliage or rust, it may be time to have your roof cleaned. These stains are difficult to get rid of, especially if the staining is concentrated in areas that don’t receive a lot of sunlight. It’s also important to make sure that your trees are properly trimmed and that any rusty chimneys are treated or replaced.

Pest Infestation

A pest infestation is a serious problem that could put your employees, customers, and clients at risk of dangerous diseases. Many pests breed quickly, so it’s important to spot them before they get out of control. Some of the most common signs of pests include small droppings, a trail of grease or oil, footprints, and more.

The best way to protect your building and its inhabitants from unwanted pests is to have a professional roof cleaning service conducted regularly. Soft washing removes not only black stains and streaks but also fungi, algae, moss, and bacteria. These organisms can cause a wide range of problems, including deteriorating shingles and causing water damage to interior areas.

Fungus and algae can grow on the shingles of your roof, lifting them and destroying them over time. They can also pull up and spread insulation, reducing its effectiveness. Similarly, moss and lichen are abrasive to shingles and can cause them to crack and chip.

Rodents like mice and rats are another major concern on business premises, as they carry diseases that can affect the health of people who work or visit the establishment. In addition to droppings, rodents are known for leaving behind greasy or sticky marks on walls and other surfaces. They also leave behind a foul smell, such as ammonia or a greasy or oily odor.

Larger pests like squirrels and raccoons are also a serious concern for businesses. They are known to chew on just about anything they can reach, including baseboards, electrical wires, rugs and upholstery, window sills, drywall, and more. If you notice unexplained holes or tears in your fabrics, it’s probably a sign of a pest infestation.

Curb Appeal

The roof of a home isn’t only an aesthetic part of the property; it also serves a practical purpose. It keeps the house insulated, protects against the elements, and more. Because of this, it needs to be cleaned regularly to prevent the buildup of debris and contaminants that can cause damage over time. However, many people don’t think of the roof as a part of curb appeal because they tend to only focus on enhancing the outdoor space of their property with things like mowing the lawn, trimming overgrown bushes, or adding mulch.

But the reality is that the roof plays a significant role in determining a property’s curb appeal. If you are looking to sell your property in the future, you want it to have a clean appearance that gives off the impression of a well-maintained structure. It will make the building look welcoming to prospective buyers, which can ultimately lead to a successful sale.

Curb appeal is a vital aspect of any property, and it is one that many real estate agents will tell you to prioritize when selling a property. It is also a way to add value to your property without spending a lot of money on large-scale renovations. Instead, you can invest in small changes that will have a big impact.

Among these, the most obvious and effective is professional roof cleaning. By getting rid of the dirt, moss, and lichen that can collect on your roof over time, you will instantly boost the overall appearance of your property. Shore Clean Solutions provides residential roof cleaning services that will help you improve your curb appeal and keep your property looking its best.
