1. Why Build a Deck Over a Roof?

A roof deck offers several advantages over a ground-level deck.

2. Planning Your Roof Deck

Before building your roof deck, you need to plan it carefully. Here are some things to consider:

Roof Access

You must have a safe and secure way to access your roof deck. This can be achieved by installing a staircase or a ladder.

Additionally, consider installing a permanent roof access hatch or ladder for safe and easy access to your roof deck. A professional can install these, providing a secure and convenient way to access your roof deck. Maintaining the access point by keeping it clear of debris and regularly inspecting it for any damage or wear is also essential.

Structural Support

A strong and stable structure will be needed to support your roof deck. This can be achieved by using support beams and joists. You must consult a structural engineer to determine the correct size and spacing of the beams and joists.

Water Drainage

Water drainage is critical when building a roof deck. You must ensure that water does not pool on your deck, which can lead to water damage and rot. You may need to install a membrane or drainage system for proper water drainage.

Building Permits

Building a roof deck may require a building permit from your local government. You must check with your local building department to determine what permits and inspections are required.
