How to Overlap Corrugated Metal Roofing

Regarding roofing options, corrugated metal sheets are the best choice. These sheets are not only fireproof but also easy to use and install. Watertightness is a critical aspect of corrugated steel roofing. This article will discuss the steps to ensure quality overlap and proper installation.

Protect Yourself

Safety is a crucial consideration before you begin installing corrugated metal roofing. This includes dressing appropriately for the job at hand. Corrugated metal roofing is a great product, but there are risks of it causing injury to those who work with it. Protect your eyes from any metal shards and debris by wearing safety goggles.

  1. Start by preparing the roof deck. Make sure it is clean, dry, and free of any debris that could interfere with the installation of the roofing sheets.
  2. Measure the length of the roof and determine the number of sheets needed. Cut the sheets to the appropriate size using a metal cutting saw or shears.
  3. Start at the bottom of the roof and lay the first sheet of metal perpendicular to the roof’s edge. Align the sheet with the roof’s bottom edge and secure it with screws.
  4. Lay the next metal sheet beside the first one, overlapping it with at least one groove. This will create a water-tight seal. Secure the sheet in place with screws.
  5. Continue laying the remaining sheets similarly, overlapping each with at least one groove. Keep the sheets aligned and level to avoid creating gaps between them.
  6. When you reach the top of the roof, you may need to cut the final sheet to fit. Use a metal cutting saw or shears to trim the sheet to the correct size and overlap it with the previous sheet.
  7. Finally, secure the last sheet in place with screws, making sure it is tightly fastened to prevent any water from entering.
