1. Planning and Design: Start by creating a detailed plan and design for the timber flat roof. Consider factors such as the size of the roof, the pitch, and the materials needed.

2. Obtain Permits: Before starting construction, make sure to obtain any necessary permits or approvals from local authorities.

3. Prepare the Site: Clear the area where the timber flat roof will be constructed and ensure that the ground is level and stable.

4. Install the Roof Structure: Begin by installing the roof structure, which typically consists of timber joists and beams. Make sure to follow the design plan and ensure that the structure is sturdy and able to support the weight of the roof.

5. Install Insulation: Once the roof structure is in place, install insulation to help regulate the temperature and energy efficiency of the building.

6. Install Roof Decking: Next, install the roof decking, which is typically made of plywood or OSB. Make sure to secure the decking properly to the roof structure.

7. Install Roofing Material: Finally, install the roofing material of your choice, such as shingles, metal panels, or EPDM membrane. Make sure to follow the manufacturer's instructions for installation.

8. Finish and Seal: Once the roofing material is in place, finish the roof by adding any necessary trim or flashing. Seal all seams and edges to ensure that the roof is watertight.

9. Inspect and Maintain: After construction is complete, inspect the roof regularly to ensure that it is in good condition. Perform any necessary maintenance or repairs to prolong the life of the timber flat roof.

Procedure of Constructing a Timber Flat Roof

1. Preparation

- Determine the span and load requirements for the roof.
- Gather and prepare the necessary materials and tools.

2. Floor Joists

- Install floor joists at appropriate spacing (typically 16" or 24" on center).
- Ensure that the joists are level and secure to the supporting walls.

3. Roof Sheathing

- Apply plywood or OSB sheathing over the floor joists.
- Stagger the joints and nail or screw them securely.

4. Underlayment

- Install a layer of roofing underlayment over the sheathing.
- This protects the roof from moisture and improves waterproofing.

5. Roofing Membrane

- Apply a layer of roofing membrane over the underlayment.
- Use appropriate materials and methods for the type of membrane (e.g., asphalt shingles, metal roofing).

6. Flashings

- Install flashings at all penetrations through the roof (e.g., chimneys, skylights).
- This prevents water from leaking into the building.

7. Roof Vents

- Install roof vents to allow for proper attic ventilation.
- This prevents moisture buildup and potential damage to the roof.

8. Edge Trim

- Attach edge trim around the perimeter of the roof to protect the edges and improve aesthetics.

9. Inspection and Maintenance

- Regularly inspect the roof for any signs of damage or leaks.
- Clean gutters and downspouts to prevent water backup.

Additional Considerations:

- Slope: A flat roof is not completely flat but has a slight slope to allow water to drain off.
- Structural Support: Ensure that the supporting walls and floor joists are capable of handling the weight of the roof and potential snow loads.
- Insulation: Consider installing roof insulation to improve energy efficiency and reduce thermal loss.
- Code Compliance: Follow all applicable building codes and regulations for the specific location.
