Thanks Have measured the actual sloping roof area not off a plan

Hi I am getting finance to undertake house renovations. The mortgage co won't lend on a house that has more than 25% of flat roof space The house has a dormer set into the tiled roof. I calculated the total roof area and then the dormer roof area. Subtracted the dormer area from total roof area which means less than 25% However a friend has said I need to calculate the actual tiled roof area and then subtract the dormer roof area. In which case it is over 25% flat roof. Does anyone know the calculation method valuation surveyors would use? Thanks
