The Best Paint for Corrugated Metal Roof: An In-depth Look at Liquid Rubber

Investing in a metal roof is a decision homeowners seldom regret. Recognized for its durability and longevity, it resists the elements better than most roofing materials. It's especially beneficial in regions with harsh winters, where its robustness provides extra insulation and prevents sagging or collapsing under heavy snowfall.

Nevertheless, to get the most out of your metal roof, there are additional measures you can take. One such step is using the best paint for corrugated metal roof - a waterproofing paint like Liquid Rubber's Waterproof Sealant.   


The Merits of Waterproofing Corrugated Iron Roofs

Before diving into the process, let's first understand why waterproofing your corrugated iron roof is beneficial. The immediate advantages include a decrease in heating and cooling expenses due to iron's natural insulating properties. Plus, the process minimizes your roof's compression and decompression during temperature fluctuations.

Understanding Why Metal Roofs Leak

Metal roofs may experience leakage due to several reasons. The most common cause is loose or missing fasteners, often resulting from extreme weather conditions like windstorms, hail, or snow. Damaged trim pieces, gaps, large seams, and rust can also contribute to leaks.

Before embarking on a metal roof waterproofing mission, ensure any damage to your metal roof is repaired. And remember to gather all the necessary items you'll need to complete this DIY project.

Waterproofing a Corrugated Iron Roof: The Materials You'll Need

Before you start, equipping yourself with the right tools and materials is crucial. Here's what you'll need:

  • Power screwdriver with hexagonal bits
  • Powerwasher
  • Brush, spray gun, or paint roller
  • Liquid Rubber Seam Tape
  • Liquid Rubber Waterproof Sealant

The Process: Inspecting and Preparing Your Roof

The first line of action involves inspecting your roof for any loose fasteners, a common issue with metal roofs due to their expansion and contraction from weather and UV exposure. A thorough inspection will reveal what needs fixing before you commence the sealing process.

  • Examine your roof carefully, checking every fastener.
  • Using your power screwdriver, tighten all loose fasteners.
  • Powerwash your roof to eliminate dirt, debris, rust, and oils.

Waterproofing Your Corrugated Iron Roof: Step by Step

With your roof now prepared, it's time to waterproof it with Liquid Rubber. Here's how:

  • Use the Liquid Rubber Seam tape to seal any cracks or seams that are over one-eighth of an inch long.
  • You can cut the seam tape to size. After removing the adhesive rear backing, apply it firmly and hold in place over any identified cracks for at least 30 seconds to create a strong, lasting bond.
  • For smaller seams and cracks, use Liquid Rubber Sealant & Adhesive Caulk to fill them in, ensuring you smooth the overlays and remove excess. Allow at least 30-60 minutes for the seam tape and 24 hrs for caulking to dry before moving on to the next step.

After the seam tape and caulking have fully dried, start sealing your metal roof with the Liquid Rubber Waterproof Sealant. If you wish to maintain a specific style or tone for your roofing, you can also opt for the Liquid Rubber Color Sealant.

  • The most effective way to apply such a sealant over a large area is by using a spray gun. These can often be rented or purchased from your local home improvement store.
  • Ensure you cover any seam tape and caulking and apply an even coat over your entire metal roofing surface.
  • Add more coats of sealant as needed, with 2-3 coats typically being sufficient to create a waterproof and weatherproof rubber membrane that will protect your roof, and by extension, your home, for many years.

Why DIY Enthusiasts Prefer Liquid Rubber

Liquid rubber technology has become increasingly popular among DIY enthusiasts due to its ease of use, affordability, and reliability. It's also VOC-free and non-toxic, making it a safe choice for your home and the environment.

What's more, it's an effective solution for various home improvement projects, including waterproofing corrugated iron roofs. Liquid rubber forms a seamless, waterproof membrane that adheres to almost any surface, providing a durable and long-lasting solution.

The Growing DIY Community

The DIY community has grown significantly in recent years. A survey by Home Improvement Research Institute (HIRI) reveals that 72% of homeowners undertook a DIY project in 2020, up by 10% from the previous year. This trend is expected to continue as more people discover the satisfaction and cost savings associated with DIY home improvements.
