F-Roof: a Multi-function, Single-layer Roof

The purpose of the F-Roof is to:

1. Protect the house from rain and snow.
2. Provide electrical energy to the house.
3. Provide food (vegetables) for the house's inhabitants.
4. Use structure as function (solar panels and plants' pots are the roof).

Why F-Roof?

Because:

1. Most of the roofs have a single function: to protect the house from rain and snow. We want more from a roof!
2. Ground-level soil should be used for growing trees, not vegetables. Vegetables have small roots that require less soil.
3. Existing roof-gardens have too many unnecessary layers, thus being expensive. One layer should be enough.
4. Soil on the roof provides thermal insulation, so the attic becomes less hot during summer.
5. The air behind solar panels could be circulated (with a fan) so the panels' temperature will be reduced and their efficiency will be increased.
6. Wood should not be utilized for construction purposes. Trees are more important than for building houses!
7. Utilize a minimal amount of materials (solar panels and plant pots have a dual purpose: they provide energy/food and make the roof's structure).

Step 1: Cut

Cut bars to the required length and angle.

Step 2: Weld

Weld trusses

Step 3: Lift

Lift trusses to the top of the house

Step 4: Connect

Connect trusses with T40 metal profiles

Step 5: Solar Side

Place solar panels on the top. Use silicon glue between them.

Step 6: Gutters

Cut gutters to length

Step 7: Plant Vegetables

Do this at ground level. It is easier this way.

Step 8: Stairs

Cut 2 stairs on which the gutters are placed.

Step 9: Balustrade

Build a balustrade to support you during garden maintenance.

Step 10: Lift Gutters

Lift gutters on stairs. Use bituminous tape to prevent water leakage.

Step 11: Result From Inside Roof

Solar panels and gutters seen from inside the roof.

Step 12: Result From Outside Roof

Solar panels and gutters seen from the outside of the roof.
