Power washing roofs and cistern clean out recomendations?

Trusted Member

Just curious, how often should you power wash your roof? Is there a good company out there? (STX)

Also I read that you need to totally drain and clean your cistern every so often. How do you know when and who does this? (STX)

Just gathering info for something I will do down the road.

While I'm asking, how often do you need to recoat your roof and who is good for this?

Thanks everyone!

I have only power washed my roof just before re-coating it. I have never cleaned my cisterns and don't plan to. I test my water annually and don't have any issues.

Depends on what the bottom of your cistern looks like.
If you're buying a home, best to do it before you move in as they must drain it, clean all the gunk, sediment and lifeforms in it, reseal it, cure it and it has to dry before you can refill it. This can take about a week that you might be without any water for anything. Some companies offer a storage tank to place water in during the process for use during this time, some don't. A hotel stay is preferable to trying to live without water for the duration.

Best to pressure wash, clean and recoat roof, prior to cleaning cistern if you're going that route.

Just remember, if pressure washing roof, if not cleaning cistern afterwards to disconnect or block up your downspouts so all the nasty stuff on roof doesn't get into the cistern and contaminate your water.

I just did mine before leaving island and decided since it was clean, I may as well go ahead and have my contractor recoat it since its been about 5-6 years since I did a top coat.

I, generally, pressure wash and clean roof, at least, every 2 years and recoat every 5-6. I like a clean roof.

Downspout screens also help keep leaves and things/critters from getting in cistern and one doesn't want tree branches overhanging the roof. More work to keep it clean. Good to place screens over your overflow pipes as well.

There are companies that advertise in newspaper and yellow pages.
Maybe someone can recommend someone they've used on STX.

We had a leaking cistern repaired and re-coated 2 years ago (STX) by Joseph the Bushmaster 340-771-4557 bushmanvi@gmail.com.

No problems since.

He was recommended by our realtor.

Other name suggested was John Beagles 340-772-1038.
