Why Roofs Stain
WHY YOUR ROOF SHINGLES ARE TURNING BLACK
Remember the first time you looked up at your roof and noticed those black stains appearing on your shingles? This is quite a common occurrence in Florida. Even on a roof with (so-called) fungus resistant shingles, the fungus protection can begin to fail as little as 1-2 years. Florida's hot & humid climate, fungus will grow on your roof shingles leaving stains that spread across the entire roof unless treated.
HOW CAN A CLEAN ROOF SAVE YOU MONEY?
Besides making your home look old and unsightly, research has discovered that fungus could actually be costing you quite a bit of money. Black fungus growth causes temperatures under your roof to become higher. Thus causing your air conditioning to run more often and this can shorten its life span. Studies have revealed a reduction of under-roof temperatures as much as 30 degrees or more, once the fungus has been removed. By lowering your attic temperature, your air conditioner can run more efficiently. With as a little as a 3-4 degree temperature reduction in you home, there could be a significant reduction in your electric bill.
WHY FUNGUS STEALS YOUR ROOFS' LIFE.
Dark fungus staining increaces surface temperatures that cause the roof to dry out prematurely, thus increasing granule loss as well. Fungus spores require three things to grow: heat, moisture and nutrients (all of which are abundant in Florida). Your roof is a perfect breeding ground for this living organism. It feeds on the organic matter contained in roofing shingles and eventually it destroys them. In short, dark colors on your roof absorb MUCH MORE HEAT!
YOUR HEALTH AND ALLERGIES.
Fungus spores growing on your home can possibly contribute to the risk of "Sick Building Syndrome" (a condition caused by increased levels of algae, mold and fungus growing in the duct work and air systems of buildings). Unhealthy fungus spores, mold and algae could conceivably be tracked into your home. For those allergy sufferers, this breeding ground can really cause some suffering.
SO, HOW DO YOU GET RID OF THIS FUNGUS?
Although cleaning the roof with a high pressure water hose might temporarily eliminate most of the visible fungus, most of the fungus remains embedded in the shingles, to quickly cause future problems. In addition, high pressure water treatments damage your shingles over time, causing granule loss and shortening the life of your shingles. Keep in mind, the granules on your shingles are the sources of not only the color of your roof, but also your heat-reflective protection. Granule loss should be avoided.
Another method is to apply chlorine to the roof and with a broom, scrub the roof and the rinse with an ordinary garden hose. Frequent use of chlorine on your roof can trigger unwanted side effects to your roof, causing shingle deterioration and brittleness, as well as causing damage to the shrubs and sod around your home. Moreover, some studies have even shown that the chlorine acts as a fertilizer to eventually promote even further growth of the fungi.
THE BEST WAY TO TREAT ROOF FUNGUS.
The best way to treat this fungus problem is to secure the services of a professional roof cleaning company. Using a liquid foam cleaner & a fungicide which kills and loosens the fungus, utilizing a low pressure clear water rinse, to flush away the dead fungus and stains
In the North Florida area (since 1992) that company is: Roof Life JAX™ Jacksonville, Florida, located in Jacksonville. This company will send trained, experienced technicians to your home to apply special, environmentally safe formulas that will not only clean the fungus from your roof once and for all, but also apply a second clear coating that remains on your roof suspended in a bonding agent that prevents future fungus growth.
After your roof has been treated and the fungus totally eliminated, a maintenance program is recommended to prevent the return of fungus. Such a program is available through Rooflife™ / Roof Life JAX, L.L.C., called The Guardian Maintenance Program.
