How to install aluminum sheets on a roof?

To install aluminum sheets on a roof, follow these steps: 1. Inspect the roof structure for any damage and ensure it can support the weight of the aluminum sheets. 2. Measure and cut the aluminum sheets to the required size using a metal saw. 3. Attach a drip edge to the eaves to prevent water from seeping under the sheets. 4. Lay the first sheet horizontally on the roof, starting from the bottom edge, and secure it with roofing nails. 5. Overlap the subsequent sheets by about 1-2 inches and fasten them with nails, ensuring a watertight seal. 6. Install flashing around vents, chimneys, and other roof projections to prevent leaks. 7. Seal all seams and fasteners with a high-quality sealant to ensure a weathertight installation. 8. Inspect the installation for any gaps or leaks and make necessary adjustments.
