Herring gulls and other birds such as rock doves in urban areas frequently nest on flat roofs. They breed once a year from April to June. Nest building begins generally in early May, and urban birds will often use the same nest year after year.
The easiest way to discourage nesting on your roof would be to check the rooftop early in May and destroy any nesting materials before eggs are laid and/or babies hatched. Gulls are persistent and if they have been nesting there before, it may take a time or two of disturbing the site to discourage them from returning.
