One sure-fire way to extend the life of your roof and possibly even lower your utility bills is to keep your roof clean. Odds & Ends Home Improvement is proud to provide roof cleaning services to homeowners in Farmville and the surrounding areas.
Benefits of Our Roof Cleaning Services
Our roof cleaning services benefit homeowners in several ways:
- Cleaning your roof removes harmful bacteria such as gloeocapsa magma that breaks down roof tile and leaves ugly black streaks on your roof.
- Having a clean roof can lower your utility bills by reducing the temperature in your home (clean roofs reflect more sunlight instead of absorbing it).
- A clean roof makes your home more visually appealing and increases its resale value.
Just take look at what a difference there is between a clean and dirty roof in the picture below. The right side of the roof in the image has been cleaned by our team, and the left side has not:
Our Roof Cleaning Methods
When we clean a roof, we use a soft-wash method that avoids damaging your roof tiles. You should never clean an asphalt roof using high-pressure spray, because it does more harm than good.
Also, we only use plant-friendly cleaners specifically designed for removing harmful bacteria from your roof without killing plants adjacent to your home. These chemicals are not harmful to humans either.
This is the roof cleaning method recommended by Angie’s List, due to the fact that it is more thorough and not harmful to the environment.
Once we complete an initial cleaning of your roof, we recommend having us come back every year to do an annual spray-off of the roof so that harmful bacteria doesn’t return. We only charge $100 for an annual spray-off of a roof for previous roof cleaning customers.
How to determine if your roof needs cleaning
If you notice black streaks or stains on your roof, it might be a sign that you have a gloeocapsa magma problem. Gloecapsa magma is a form of bacteria that produces a water-generating oxygen gas, and is becoming increasingly common on roofs in the southeast U.S. Once it’s on your roof, this bacteria doesn’t go away without proper cleaning, and in fact it will spread over more of the roof each year if it isn’t cleaned. It breaks down the roof tile and shortens the life of the roof significantly.
If you suspect that your roof has this problem, you should contact us right away to schedule an inspection and get a quote for roof cleaning services.

Frequently Asked Questions About Roof Cleaning
Q: Why does my roof turn black?
A: The short answer is that it is algae. It grows on the north side and shaded areas of your roof.
The long answer: Gloeocapsa Magma is the primary species of algae causing your roof to turn black. Milled or compounded limestone is used as a filler in roof shingles to add weight and flexibility for the shingle. Shingle manufacturers started using limestone, which is calcium carbonate, in the late 70’s when the first energy crises hit and petroleum became expensive and was in short supply. Limestone is apparently a superior filler product and most shingle manufacturers are reluctant to go back to the old methods or to try new products.
The problem, is that algae loves limestone because of its alkalinity and solubility, it provides a stable environment and a food source for the algae to flourish. It thrives in warm, humid environments and normally appears on the north facing slope or shaded areas of your roof where the lack of sun and abundant moisture (like morning dew) supports its growth.
These Algae spores are carried by the wind and land on your roof. You may first notice it as little black stains on your roof that just seem to explode over the course of a year. It’s growth is exponential, the more it spreads the more moisture it can hold to aid it’s growth. As it grows, it will spread to adjacent homes which is why you will see it on so many roofs in the same area.
Q: Will algae damage my shingles?
A: The shingle manufacturers say that while the algae is unsightly, it does not damage or harm the shingles.
After many years in the roof cleaning business, I can say that it does seem to do some damage. Older roofs with a lot of algae seem to lose more granules. As the algae feeds and spreads, it loosens this protective layer of surface granules which play a very important part in solar reflectivity.
The loss of these granules, combined with the black growth spreading across your roof will cause the roof to absorb heat from the sun up on a sunny day. Your attic will be much hotter than necessary and this usually translates to the upstairs of your home being a little warmer, as the heat from the attic radiates into that upper floor. While this might be fine in the winter, it can be a source of higher electric bills in the spring and summer months as your air conditioner struggles to keep up.
Q: How long will my roof stay clean after you finish?
A: The average roof cleaning will usually last three or more years depending on the amount of shade around your home. If you are under a lot of trees and the roof stays shady for a good portion of the day, then the algae will certainly return a little faster. Homes that do not have many trees around them tend to stay cleaner much longer. Just remember, Heat and humidity play a big role in helping the algae thrive. We recommend signing up for 6 month check-ups and yearly treatments to help fight the algae.
Q: My roof has moss on it. Can this be cleaned?
A: The answer is yes. We have developed a few methods to effectively clean moss off of roofs. If you are dealing with a letter from your insurance company that is requiring you to clean the moss and algae of off your roof, please tell us about it when you call or email. We have helped many homeowners deal with that problem.
Q: How do you clean my shingles?
A: We use air powered pumps to lightly dispense the cleaning detergents on the roof. No pressure washers are used in our process. The detergents do all the work to clean the roof and we then rinse with garden hoses. This follows the method the shingle manufacturers themselves recommend, meaning no pressure.
Q: I have seen some roof cleaning websites with the “Certified Roof Cleaner” logo? Is your company certified?
A: There is no “recognized” certification process in our industry. Any claims to certification that you may see in the roof cleaning industry are usually nothing more than a piece of paper and a nice logo purchased online. There are several websites that have recently appeared, where, for a fee, anyone can subscribe and get some online roof cleaning training, a tee shirt and a certificate implying they are now certified to go clean roofs. So the answer would be no, we are not certified. We have cleaned many roofs in the local area and rely on that experience to provide a high level of service to our clients.
Q: Does bleach, damage shingles?
A: Bleach does not damage shingles.
These days, most professional roof cleaning companies use bleach in their roof cleaning mix. The Asphalt Roofing Manufacturers Association (this would be the trade association that represents companies that make shingles) have said the proper method of cleaning a roof involving the use of bleach, soap and low pressure.
The non pressure, or low pressure cleaning process is the only method approved and endorsed by shingle manufacturing companies.
Q: Will your detergents kill my plants and shrubs?
A: No. We take many precautions to ensure that the roof cleaning is done safely and effectively. Yes, it is a light bleach solution, but it is easy enough to control. We have a variety of methods we use to ensure that no plant or shrub is damaged.
Q: I have seen some “Do it yourself” roof cleaning solutions at my local home improvement store. Are these cleaners effective?
A: I have seen instances where they have worked after a couple of applications and a couple of months waiting. The best way to answer this question would be to tell you to pick one of the products, then go to amazon.com or similar site and read the customer reviews.
Q: Do zinc or copper strips work to help prevent black roof stains? Are they effective?
A: Based on our experience with them I would say they work, but only for a limited time. The effect of the strips seems to degrade over a period of years. There is also a distance factor. The width of the zinc strips determines how much area of the roof it can cover.
We offer the service of installing either zinc or copper strips for preventive measures in keeping your roof clean. As well as 6 month checkups and annual roof treatments
Q: Can I seal my roof to prevent algae growth? I have seen a few companies that sell a roof sealant / preventative.
A: I have seen these companies and I am not sure how effective they are. They must first clean the roof and then apply the sealant.
If it is something you are thinking about, we recommend doing lots of research because it seems like the process creates more problems than it solves especially with any warranties you may have.
Need to know:
Lichens and Moss – are one of the more sticky components to a roof cleaning. If you use bleach to clean your roof, you will kill all the moss and lichens. However, these will not fall of your roof immediately and sometimes may take 2-3 months to come off. Lichens and Moss have a thicker root system than the algae growing on your roof. This root system sets itself directly into the granules of the shingles. When the roof is treated, these growths die, but it takes a while for the root system to disintegrate and let go of the roof. We brush to remove most of the Lichens and moss as we can. This is why we recommend a 6 month checkup and annual rinse treatment re applying an algae deterrent
We understand everyone needs immediate results from your cleaning and can’t wait for the rain to rinse the roof, so we focus on the troubled areas, roadside view to give you the immediate results.
