The flat roof on a friends garage has lost most of the chippings that were put on to protect it. Is it ok just to apply more chippings/grit? How deep should the grit be applied? The felt looks in good order.

You should apply a coat of bitumen emulsion first. This sets semi hard and hold the chipping in place. Sweep all the chipping into a heap where you intend finishing, brush on the emulsion in a 1m or 36" wide strip, with a soft long handle sweeping brush, then with a shovel spread the chipping evenly over the emulsion. repeat till you finish. Don't stand on the emulsion as it sticks to your foot wear and any where you walk, its a sod to get off.
