New porch roof ... But what to put up there?

[Webbieads]

Hi there, am new to all this so please be kind! We are renovating a bungalow and have built a new porch entrance. The main roof has been completed now but we are unsure how to do the porch roof (hindsight should have done it at the same time as the main roof) but naively thought it was just a small simple job. You will see by the photos space is tight. There seems to be a number of solutions but not sure what is best. Head height could be an issue and the gutter. We are looking at a warm roof using Optim R insulation. Or a lean to triple glazed conservatory style roof. Am going round in circles. Any advice would be much appreciated.
