Safely and Effectively Scrub Algae from Your Roof with these Tips from Ottawa Roofing Companies
Keeping your roof clean may seem like a huge challenge, but the benefits of regular cleanings are indispensable. By preventing the build-up of algae and mould, you can extend the lifespan of your roof and prevent contaminants from entering your home, preventing costly damage. With these tips from roofers, Ottawa homeowners can safely and effectively keep their roofs clean all spring and summer.
You Will Need:
- Cleaning solution (make your own with 1L of bleach, 3.5L of water, and 60ml of trisodium phosphate)
- A pump sprayer
- Safety goggle and rubber gloves
- A garden hose
- A broom with a scrub brush head
- Painter’s drop sheets
- Slip-resistant footwear
- A ladder
- A buddy (with a rain poncho or other protective covering)
Before You Begin
Mix your cleaning solution in the tank of your pump sprayer (never use a pressure washer – it can severely damage your shingles). Cover the areas directly under your roof with drop sheets, especially if there are plants or shrubs there that may be damaged by bleach. Make sure to handle your cleaning solution with proper safety gear. If the roof is too big to handle on your own, call a local Ottawa roofing company.
Cleaning Your Roof
With a buddy to hold your ladder steady at all times, use your pump sprayer to cover an area of your roof with cleaning solution. Roofers in Ottawa typically suggest doing this on a cool day, and letting the solution sit for 15 minutes. Then, gently scrub the shingles, before rinsing them off with your garden hose. Move onto the next area and repeat the process.
If your roof is large enough to necessitate climbing onto the roof itself, then begin by cleaning lower sections first, and then letting them dry completely. This way, you will always have a dry surface to stand on. Also make sure to wear a safety harness and be careful at every step along the way. If you don’t think that you can do the job safely, call an Ottawa roofing company immediately.
Did you know that copper and zinc are toxic to algae? It’s true, and it’s not just great information for your weekly pub trivia night. By installing a strip of one of these metals underneath the shingles that form the apex of your roof, you can protect it from future infestations. Every time it rains, zinc or copper will wash over your shingles, slowly coating them in a fine dusting that will inhibit algae growth. If you’re interested in getting a protective strip added, ask your roofers in Ottawa about it today!
