Black algae is a form of microorganism that can develop in your pool, deck or even in between your roofing shingles, and is quite a task to remove. This is a dangerous addition to your roof, as it chips away at the strength of your shingles, not to mention that it could severely diminish your home’s resale value. Here are some valuable tips on how to get rid of it, prevent it from returning, and know when there’s nothing you can do so you can call in trusted roofing contractors in DC:
Cleaning with Chemicals
Various chemical cleaners are available that can help you get rid of moss, algae, or other types of bacterial growth on your roof. The thing to remember though is to always make sure that the chemicals you’re using won’t pose a new, perhaps worse danger to your roof shingles. You can use a mixture of trisodium phosphate, or various commercial roof cleaners.
Roof Safety Gear
An article posted on TodaysHomeowner.com advises that you should gear yourself up against the dangers of a steep, wet slope whenever getting on your roof to clean:
Avoid working on steep roofs, wear slip resistant shoes, and use a safety rope where needed. When working with harsh chemicals, be sure to protect your skin and eyes.
The article also suggests that you use:
To clean your algae-ridden roof, pour your cleaning solution into a garden sprayer, apply it on the damaged surface, and allow it to remain on the roof for at least fifteen minutes.
After ridding your roof shingles of the annoying algae, try having a strip of copper-coated sheet metal installed along your roof’s sides, just below the ridge. This should serve to discourage algae growth and development. On the other hand, replacing your roof through installers like Maggio Roofing might be a more viable and less frustrating option as opposed to maintaining a severely damaged or algae-infested roof and causing further damage.
An efficient roofing contractor in Washington, DC should be able to offer you reliable roof replacement or repair services, whichever you might need. If you plan to sell your home in the near future, check it for black algae as soon as possible and take the necessary course of action.
