Understanding Standing Seam Metal Roofing

What is a Standing Seam Metal Roof?

A standing seam metal roof is a type of metal roofing system characterized by raised seams or vertical legs that stand above the level of the roofing panel. These seams are then connected with concealed fasteners, creating a sleek, continuous, and watertight roofing surface. Standing seam roofs are known for their modern and clean appearance.

Advantages of Installing a Standing Seam Metal Roof Over Shingles

  1. Energy Efficiency: Metal roofs, including standing seam options, are highly reflective, meaning they reflect sunlight rather than absorbing it. This can result in reduced cooling costs during hot months.
  2. Durability: Metal roofs are known for their longevity. They can last 50 years or more, far exceeding the lifespan of most shingle roofs.
  3. Minimal Maintenance: Metal roofs require very little maintenance, with occasional inspections and cleanings being the primary tasks.
  4. Weather Resistance: Metal roofs can withstand a wide range of weather conditions, including heavy rain, snow, hail, and high winds.
  5. Environmentally Friendly: Many metal roofing materials are recyclable, making them an eco-friendly choice.

The Installation Process

1: Assessment and Preparation

  • Begin by assessing the condition of your existing shingle roof. It should be in reasonably good shape with no major issues.
  • Repair any damaged shingles, and ensure that the roof deck is solid and capable of supporting the additional weight of the metal roof.

2: Installation of Strapping or Purlins

  • Install wooden strapping or purlins over the existing shingles. These provide an even surface for the metal roofing panels and create an airspace for ventilation.

3: Metal Roof Panel Installation

  • Start installing the standing seam metal roofing panels from the bottom of the roof, working your way upward.
  • Secure each panel with concealed fasteners, ensuring that the seams overlap correctly to create a watertight seal.

4: Ridge and Flashing Installation

  • Install ridge caps at the roof’s peak and flashings around roof penetrations like chimneys and vents to prevent water infiltration.

5: Finishing Touches

  • Finally, complete any finishing touches, such as sealing seams and cleaning up the work area.

Considerations Before Installing a Standing Seam Metal Roof Over Shingles

Before making this roofing choice, consider the following factors:

  1. Local Building Codes: Check with your local building department to ensure that this type of installation is allowed in your area.

It offers numerous benefits, from energy efficiency to longevity, and provides a sleek and attractive appearance.

With the right approach, a standing seam metal roof can enhance your home’s aesthetics and performance for many years to come.
