What Do You Need to Install Before a Metal Roof?
Successful metal roofing installation begins with proper preparation. Before the metal panels are secured, there are multiple layers that need to be installed to offer structural support, insulation, and water resistance.
Roof Deck Inspection
Prior to proceeding with the installation, check the current roof deck for any rot, deterioration, or structural weakening. The deck should be sturdy, as underlying problems can taint the strength of the new metal roof. If there are compromised sections, replace the compromised areas with corresponding plywood or oriented strand board (OSB).
Roofing Underlayment
Underlayment is a waterproof barrier installed between the metal panels and the roof deck. It has several functions:
- Prevents water penetration
- Improves insulation
- Reduces rain or hail noise
Typical underlayment types are:
- Synthetic Underlayment: Constructed from heavy-duty polypropylene or polyethylene, it is lightweight, tear-resistant, and provides excellent water resistance.
- Felt Paper (Asphalt-Saturated): A traditional type, 15-pound and 30-pound options, providing moderate water resistance.
- Peel-and-Stick Membranes: These self-sticking membranes offer optimal leak protection and are best suited for icy dam areas.
The underlayment must be installed from the eaves up, overlapping each course at least 6 inches so water runs off from the building.
Drip Edge Installation
A drip edge is a piece of metal flashing that is used along the edges of the roof to keep water from entering between the panels. Fasten the drip edge with roofing nails 12 inches on center. Have the overlapping portions sealed with a waterproof adhesive so that there will be a solid barrier against water.
What Do You Put Under Metal Roofing?
In addition to underlayment, there are other materials that are important in providing a durable and effective metal roof installation.
Insulation
Adding insulation beneath a metal roof improves energy efficiency and avoids condensation accumulation. Some common insulations are:
- Rigid Foam Insulation: Offers superior thermal resistance (R-value) and is water-resistant.
- Spray Foam Insulation: Seals gaps well but needs professional installation.
- Reflective Radiant Barriers: Minimize heat absorption, which makes them suitable for hot climates.
Roofing Battens (Optional)
Roofing battens are metal or wood strips placed over the underlayment to create a gap of air between the metal panels and the deck of the roof. They give:
- Improved ventilation
- Additional support to panels
- No heat transfer to the attic
Battens are particularly effective for standing seam metal roofs where direct contact with the roof deck can limit airflow.
Can I Install a Metal Roof by Myself?
While installing a metal roof is possible for experienced individuals, it requires careful planning, precise execution, and adherence to safety protocols. Here are few steps that can help you in the installation.
Step 1: Gather Required Tools and Materials
The necessary tools include:
- Tape measure
- Chalk line
- Drill with various bits
- Metal snips
- Screw gun
- Safety harness
- Ladder or scaffolding
Materials required:
- Metal roofing panels
- Screws with neoprene washers
- Closure strips
- Ridge cap
- Eave and gable trim
- Sealant and butyl tape
Step 2: Install the Metal Panels
- Positioning the First Panel: Start at the eaves and make sure the first panel is square with the roof edge. A ¾-inch overhang is recommended.
- Securing the Panels: Use screws with neoprene washers, placing them along the panel’s ridges instead of valleys to prevent water pooling.
- Overlapping Panels: Panels should overlap by at least 1 inch, depending on manufacturer guidelines.
- Applying Sealant: Apply butyl tape along overlaps to create a watertight seal.
Step 3: Install Flashing and Trim
Flashing and trim help seal vulnerable areas and provide a finished appearance.
- Ridge Cap: Covers the peak of the roof and guarantees proper ventilation.
- Valley Flashing: Installed where two roof sections meet to direct water runoff.
- Sidewall and Endwall Flashing: Used where the roof meets a vertical wall.
- Eave and Gable Trim: Installed at the edges to protect against wind uplift.
Step 4: Final Inspection and Clean-Up
- Check for loose fasteners and secure them as needed.
- Make certain all seams are sealed to prevent leaks.
- Remove any metal shavings or debris to prevent rust formation.
When to Call Professionals
While a determined homeowner can install a metal roof, certain situations call for professional expertise:
- Complex Roof Designs: If your roof has dormers, skylights, or multiple slopes, a professional installer can make sure of proper waterproofing.
- Steep Roof Pitch: Roofs with a pitch steeper than 6:12 require specialized equipment and experience to install safely.
