Cleaning Mold Mildew Stains Tampa Roof


Do you have Mildew or Mold (black streaks) on your Tampa Roof ?

You have 3 ways to eliminate a black algae covered roof:

1. Replace your roof for thousands of dollars.
2. Pressure Wash your roof and void your warranty.
3. Chemically remove the ugly algae stains and save your roof.

What You Should Know About Cleaning Mold Mildew Stains From Your Tampa Roof!

Asphalt shingles are made with a limestone base, food for all algae that attaches to a shingle surface. So, as long as manufacturers continue to use limestone as a base, stopping algae growth will continue to be a major problem. Mold and mildew stains comes from a spore carried by the wind, birds, and squirrels from one infected roof to another. There the algae grows until it is cleaned. The algae growing on your roof will reduce the life of your shingles and remove the granules that are the color and the protection.
Our Roof Cleaning Chemical called “Apple Sauce”, saferly removes the mold and mildew stain that is growing on your roof w/o Pressure Washing. It also contains a mildecide that helps to retard the algae growth. Studies have shown that it takes between 2 and 3 years for some algae spots to surface. This is a good time to have a roof sprayed with our Patented Roof Treatment Chemical before the algae has spread. It takes substantially less roof cleaning chemical to clean a roof early in the algae growth. Keeping your roof clean, treated, and properly ventilated will add years to your roofs life. After cleaning the roof, it is recommended that a yearly treatment be applied to the surface to help protect the shingle granules from beoming re infected with Mold and Mildew Stains.

Partial Tampa Roof Cleaning Not Recommended


Partial Tampa Roof Cleaning Not Recommended

Roof stains in Tampa usually first appear on the northern-facing areas of a roof surface, as you’ve no doubt noticed. This is because these areas receive less sunlight in the Northern Hemisphere (it’s the other way around in the Southern Hemisphere, as roof cleaners in Australia could attest to). Sunlight aids in drying out the southern-facing slopes much more quickly after a rain, and since roof algae growth in Tampa is accelerated by moisture, you can see how sunlight plays a role. Direct UV rays from the sun also aid in retarding the growth of algae on these surfaces.

However, it’s important to understand that even though the sun helps to slow the growth of algae on southern-facing surfaces, it does not stop it. If you have stains beginning to develop on the northern-facing surfaces of your Tampa roof, it means that it’s just a matter of time before the entire roof is covered with algae stains. You might not yet see black stains on the southern-facing surfaces, but that doesn’t mean that algae hasn’t already taken root and begun to multiply in these areas.

That’s why it’s a good idea to have the whole roof surface cleaned, even though it may appear that stains are confined to one side of the roof. If you can see it somewhere on the roof, that means it’s everywhere on the roof. You can demand that your Tampa roof cleaning contractor only cleans the area where you can actually see black stains, but don’t be surprised when, 12 months later, that area is still clean but the rest of the roof is suddenly covered in now visible black algae.

Here is a good roof cleaning article:
On roofs afflicted with algae, cleaning is a good idea
Submitted by SHNS on Mon, 09/14/2009 – 13:25 By SUSAN BANKS, Pittsburgh Post-Gazette
As if homeowners don’t have enough chores to keep them busy, many shingle manufacturers now recommend periodic cleaning of the roof surface.
You heard right. Many roofs need to be washed to keep them in good shape.
The black streaks seen on many roofs are algae growth which, left unchecked, can shorten the life expectancy of the roof by feeding on the limestone filler used in some newer shingles, according to GAF Materials Corp. of Wayne, N.J., a manufacturer of roofing products since 1886. Proper cleaning can kill the algae.
Frank Shuster of South Park, Pa., noticed the stains on his roof several seasons ago. After replacing the original roof, which Shuster says never had an algae problem, he noticed the unsightly streaking on his new roof about three years after it was installed.
“It was downright ugly,” he says.
He climbed up on the roof with a jug of chlorine bleach to see if it would alleviate the problem. It did, but he says the idea of cleaning the entire roof with bleach did not appeal to him, so he called several roofing contractors about the problem to no avail.
After seeing a flier distributed by Pittsburgh Roof Cleaners, he made arrangements with the company to have his roof cleaned. According to company owner Michael Inks, this type of service is relatively new to Pittsburgh but is quite common in the hot, humid Southern states, where algae can be an extreme problem.
Afflicted roofs have dark streaks that are usually most prominent on the lower section of the roof and taper off as they reach the ridge. The discoloration is caused by the algae’s protective sheath, which turns dark to protect the organism from ultraviolet rays.
Inks first heard about roof cleaning from a man in West Virginia.
“I went to visit the guy and he took me out to a couple of jobs and showed me how it works,” he says.
While algae issues are more serious in the humid South, other parts of the country can have problems too, especially on northern exposures, which receive less sunlight.
Inks’ process, which uses a proprietary solution that includes bleach, can be performed on most roofs in about two hours. Cost starts at $395.
Shuster, whose bill was $525, asked if the cleaning solution would damage his landscaping.
“I was really concerned about overspray and the wind blowing some of these chemicals on my shrubs,” he says. “But they covered the shrubbery and also hosed it down with water during the procedure.
“The vast majority of what they applied went into the rain gutters.”
The need for roof cleaning depends on the severity of environmental contaminants, the frequency of rainfall, the propensity for dirt and dust accumulation, the roof slope and draining characteristics.
There are cleaning recipes available for the do-it-yourselfer, but GAF recommends that the job be left to professionals.
Inks’ company provides a two-year warranty against the return of streaks and offers extended maintenance contracts. It also can clean slate and tile roofs.
If you are thinking of putting on a new roof, you can try to eliminate the need for this chore by requesting that your contractor install algae-resistant shingles.
