Asphalt resurgence (the formation of asphalt bubbles over the gravel on your roof) should not worry you. It indicates that there was enough asphalt spreaded by the roofer. The asphalt that roofers use protect your roof from sun damages as much as the gravel.
A regular maintenance of your roof drain to make sure no debris are blocking it can prevent damages to occur to your flat roof.
White roofs help prevent urban smog.
Asphalt and gravel roofs normally last for 20 years, after what their durability ca be decreased.
