Will it pay for itself?
For most homeowners, yes — through a combination of lower heating bills (typically 30–50% off conservatory-related energy cost), a year-round usable room rather than a wasted one, and the property-value uplift of a thermally efficient extension. A well-installed solid roof typically pays back in comfort and resale within a few years.
