Yes, it is possible to install an aluminum strip roof without a professional, but it requires some basic knowledge of roofing and carpentry skills. You'll need to measure and cut the aluminum strips to fit your roof, secure them with nails or screws, and ensure proper overlap for water resistance. It's important to follow the manufacturer's instructions and safety precautions. However, if you're not comfortable with DIY projects or if your roof is complex, hiring a professional is recommended to ensure the job is done correctly and safely.
