The Importance of Cleaning in the Missouri Climate

The extreme seasonal changes in the state of Missouri (from hot, humid summers to below-freezing winter temperatures) can put any roof through its paces. Metal is strong, but it may have accumulated debris and picked up algae and rust. Leaves, dirt, and organic build-up induce moisture retention, which facilitates corrosion. A clean metal roof would also bounce heat more easily, resulting in cooler temperatures in the attic space and lower energy bills for Missourians during the high point of summer.

Regular maintenance, cleanings, and checkups a few times a year are administered to catch little problems before they become bigger ones. FRG officials say these cleanings are part of routine maintenance — it’s not just surface sparkle; it’s long-term preservation.

Safety First: Before You Start

Always start any project with safety first on your list. 

This timing is critical, considering Missouri’s varying weather: morning dew, afternoon heat. Pick an overcast day without rain for more grip and less sun glare.

Essentials:

• Always work with a partner.
• OSHA-Rated Ladder or Roof Anchor and Fall Protection Harness
• Wear slip-resistant shoes, gloves, and protective glasses.

Low-Pressure Rinse

Deck your garden hose down to low pressure and completely cleanse away all surface debris. Rinses most dirt and leaves without scrubbing, won’t erode the roof finish.

Gentle Detergent Wash

You want about ¼ cup per gallon of water to create a soapy mixture. You can use a soft-bristle brush on the end of a pole or even microfiber cloths to get at those high-up areas and do it much more safely!

Tackle Mold, Algae, or Mildew

If you see a little bit of organic growth, either mix one part bleach with eight parts water or some laundry detergent and bleach. Use sparingly, gently rub and rinse well.

Rust or Stain Spots

If you just have light rust staining, remove any abrasive contact (i.e., steel particles sitting on nearby surfaces) and follow up with a soft, mild abrasive cleaner and rinse as needed.

Rinse and Inspect

Rinse every cleaning area completely. Dry it and check for dented panels, loose seams, or scratched paint that may require repair.
