Why Choose Steel Roofing?

Steel roofing is known for its durability, longevity, and energy efficiency. By opting for steel roofing, you can enjoy several benefits:

  1. Longevity: Steel roofs have a long lifespan, often lasting 50 years or more, which is significantly longer than traditional asphalt shingles.
  2. Durability: Steel roofs are resistant to extreme weather conditions, including high winds, hail, and heavy snow loads, making them an excellent choice for various climates.
  3. Energy Efficiency: Many steel roofs are designed with reflective coatings that reduce heat absorption, helping to keep your home cooler and potentially lowering your energy bills.
  4. Minimal Maintenance: Steel roofs require minimal maintenance, with occasional inspections and cleanings to ensure they continue to perform at their best.

Steps to Put a Steel Roof Over Shingles

Here’s a step-by-step guide to help you get started:

1. Roof Inspection and Preparation

  • Inspect the Existing Shingles: Before you begin, carefully inspect the existing shingles for any signs of damage or issues. Replace any damaged shingles or fix structural problems.
  • Clean the Roof: Remove debris, dirt, and moss from the existing shingles. A clean surface is essential for ensuring proper adhesion of the steel roofing.

2. Measure and Order Materials

  • Measure the Roof: Accurate measurements are crucial. Measure the dimensions of your roof to determine how much steel roofing material you’ll need.
  • Order Steel Roofing: Once you have the measurements, order the steel roofing panels, trim, and necessary accessories from a reputable supplier.

3. Install Roof Underlayment

  • Lay Down Roof Underlayment: Install a high-quality roofing underlayment over the existing shingles. This provides an additional layer of protection against moisture and ensures a smooth surface for the steel panels.

  • Begin Installation: Start at the lowest edge of the roof and work your way up. Follow the manufacturer’s instructions for panel installation, including overlap and fastening guidelines.
  • Secure the Panels: Use roofing screws with rubber gaskets to secure the steel panels to the roof deck. Pay close attention to fastener spacing to ensure stability.

5. Install Trim and Flashing

  • Install Trim: Use metal trim pieces, such as eave trim and ridge cap, to finish the edges and corners of the roof.
  • Flashing Installation: Properly install flashing around roof penetrations, such as vents and chimneys, to prevent leaks.

6. Inspect and Maintain

  • Roof Inspection: After installation, inspect the entire roof for any loose fasteners, gaps, or areas that may need attention.
  • Regular Maintenance: While steel roofs are low-maintenance, occasional cleaning and inspections are recommended to ensure they continue to perform well.
