"Your roof might look be an eyesore, and look ugly, but so what its not costing me anything. Right?"
Wrong!! A stained roof costs real money!
Its costing you money through:
- Shortened roof life
- Increased energy costs
- Reduced property values
those black stains are eating into more than your roof!
Shortened Roof Life: $4000 1
A 25-year roof may not even last 15 years if nothing is done. Here's why: As the algae and fungus grow on your roof, they eat away the base of the shingle and expand and contract with the outside temperature. This growth and movement loosens the granules, creating premature granule loss, dramatically shortening the life of your roof. The algae and fungus don't go away in the winter, they just become dormant, waiting for spring.
Increased Energy Costs: $100 every year2
The algae, mold and fungus covered roof will absorb more heat due to its black pigmentation. keeps temperatures a lot higher by preventing the reflective capabilities of the granules from doing their job. Convection stored in upper levels of the home is unable to dissipate heat due to the insulating factors these soaring temperatures make your air conditioner work a lot harder and increase your electric bills sometimes as much as several hundred dollars a year.
Reduced Property value: $10,000 3
A stained roof can send up red flags to many buyers. 40% of curb appeal is the roof, and in less than 3 seconds, potential buyers will determine that they don't want a home. If the roof is dirty, or covered with Algae or Black stains, the potential buyer makes snap decisions about your ability to care for the home, and assumes that the home has further problems on the interior. Or worse, a buyer will negotiate the cost of roof replacement into the price of the home.

1. A roof that last 15 years instead of 25 would be a loss of 40% of the roof cost on average, $3,200 - $4,800.
2. Experiments conducted at the LBNL suggest that for the PVC roofing materials
studied that are covered with algae, cleaning with algae-cleaners has practically restored the solar reflectance of the
weathered roofing membranes to the solar reflectance of the unweathered membranes. see http://www.osti.gov/bridge/servlets/purl/860745-BAdlvk/860745.PDF for 15 pg study and results.
3. An average roof replacement costs between $8,000 and $12,000.
