What are Closure Strips for Metal Roofing?

Closure strips are thin strips of foam or metal that are strategically positioned between metal panels and the roof surface. They serve to act as a barrier against moisture, pests, debris, and air infiltration. Closure strips help create weather-tight and energy-efficient roof systems that are long-lasting and durable.

Why Do I Need Closure Strips for Metal Roofing?

Closure strips are essential for metal roofing because they provide several benefits, such as:

  • Weather Resistance: Closure strips create a tight seal over your roof that helps it remain impervious to rain, snow, wind, and hail. They also prevent water from seeping through the seams and fasteners, which can cause corrosion and damage to the roof structure.
  • Energy Efficiency: Closure strips help create a stable indoor temperature by blocking air leaks, significantly decreasing heating and cooling costs. They also reflect heat and sunlight, reducing the thermal load on your roof and improving its performance.
  • Lifespan Extension: Closure strips help mitigate corrosion and moisture-related damage, prolonging the lifespan of metal roofs. They also protect the metal panels from denting, scratching, and warping, maintaining their appearance and quality.
  • Noise Reduction: Closure strips also serve to dampen noise generated by heavy rainfall or hail, providing some much-needed relief during stormy conditions.

What Types of Closure Strips are Available for Metal Roofing?

There are various types of closure strips available for metal roofing, depending on the type of metal panel, the shape of the roof, and the installation method. Some of the common types are:

  • Inside Closure Strips: These are placed under the metal panels along the eaves, valleys, and hips of the roof. They fill the gaps between the panel ribs and the roof deck, preventing water and air from entering the roof cavity.
  • Outside Closure Strips: These are placed over the metal panels along the ridge, rake, and gable of the roof. They fill the gaps between the panel ribs and the ridge cap or trim, preventing water and air from escaping the roof cavity.
  • Universal Closure Strips: These are designed to fit any type of metal panel, regardless of the rib height or spacing. They are flexible and adaptable and can be used for both inside and outside applications.
  • Profile Closure Strips: These are custom-made to match the exact profile of the metal panel, ensuring a perfect fit and seal. They are more expensive and less available than universal closure strips, but they offer better performance and aesthetics.

How to Install Closure Strips for Metal Roofing?

The installation of closure strips for metal roofing depends on the type of metal panel, the type of closure strip, and the type of roof. However, some general steps are:

  • Measure and Mark: Measure the length and width of the metal panels and the roof surface, and mark the locations where the closure strips will be placed. Make sure to align the closure strips with the panel ribs and the roof edges.
  • Apply Adhesive: Apply a bead of adhesive or sealant along the marked locations, following the manufacturer’s instructions. Make sure to use a compatible and high-quality adhesive or sealant that can withstand weather and temperature changes.
  • Press and Secure: Press the closure strips firmly onto the adhesive or sealant, making sure to align them with the panel ribs and the roof edges. Secure them with screws or nails, if needed, following the manufacturer’s instructions. Make sure to use corrosion-resistant and color-matched screws or nails that can blend with the metal panels.
  • Install Metal Panels: Install the metal panels over the closure strips, following the manufacturer’s instructions. Make sure to overlap the panels properly and fasten them securely to the roof deck. Apply caulk or sealant to any seams or openings that may allow water entry.
