Roof extension

We are wanting to put a porch/roof extension to the side of our lounge (approx 6sqm). The current roof is concrete tile (probably early 70s square profile) and we don’t think anything else would look right as it is quite a visible area we do have a few stacks of the tiles but need to understand how many would be required so that we can determine if there would be enough. The current eave is 1/3 of the space already and I think the current pitch is possibly around 22 degrees. The area is over an old concrete block deck which was built as part of the house as they also did back in the 70s
