Where To Screw Metal Roofing

Where to screw metal roofing depends on the panel type and roof structure you have. Metal roof screws go into the valleys or flat areas of the panels, never into the raised ribs. You screw through the metal into the wood or steel framing below. Most screws go in a straight line along each panel. The right placement keeps your roof watertight and strong for decades. According to RubyHome, metal roofing lasts 40 to 80 years, so proper screw placement matters for long-term durability.

Screw Placement on Corrugated Metal Panels

Corrugated metal panels have wave-like ridges and valleys. You always screw in the valleys, never on top of the ribs. The valleys are the low spots between each wave. Screwing here gives you a flat surface and a good seal. Place screws every 12 to 18 inches along each valley line.

Use self-tapping metal roofing screws with rubber washers. The washer sits under the screw head and seals the hole. This stops water from leaking in around the screw. According to industry data, corrugated metal costs $5.50 to $11.50 per square foot installed, so protecting that investment with correct screw placement is key.

Screw Placement on Standing Seam Panels

Standing seam metal roofs have tall vertical ribs that run up the roof. These ribs lock together. You never screw through the seams themselves. Instead, use clips that hook over the seam. The clips then screw into the decking below. This keeps screws out of the panel joints where water can enter.

Space clips 2 feet apart along each seam. Standing seam panels cost $10 to $17.05 per square foot, according to RubyHome. Proper clip placement protects your investment and maintains the roof’s watertight design.

Why Metal Roofing Matters for Your Home

Metal roofs are growing in popularity. According to RoofLink, metal roofing holds 17% market share in residential roofing. More homeowners choose metal for durability and energy savings. When you screw metal panels correctly, they resist storms, wind, and hail for many years.

Wrong screw placement causes leaks and rust spots. Water creeps in around poorly placed fasteners. This shortens the roof’s life and causes interior damage. Taking time to screw panels in the right spots protects your home and your money. Always use corrosion-resistant screws rated for metal roofing. Never reuse old screws or use regular wood screws. Metal roofing screws are designed to seal and hold properly under stress.
