When planning a DIY patio or carport, one of the most important decisions you’ll make is choosing the right roofing type. Two of the most popular options for Australian homes are insulated roofing and V-Line single skin roofing. Each option offers different benefits depending on your budget, comfort expectations, and how you plan to use the space.
In this guide, we break down insulated vs V-Line roofing to help you choose the best solution for your patio or carport project.
