The small cracks are an indication, as Paul states, that the gell coating is failing due to UV exposure. Whet your finger and rub it along the roof's surface. If a white deposit results, the gell coating is/has broken down. The size of the cracks and their depth will determine the repairs. If they are strictly a surface spider web type of cracking, and there are no open gaps, the surface can be easily repaired and recoated. If the cracks are substantial and a cloth print is noticeable, the repairs will be more involved. Once you have determined the severity of the damage, specific instructions can be addressed, that most DIYers will be able to effect. Fiberglass fabrication is much easier and less expensive than metallic restorations. It can be somewhat messy at times, but few tools are necessary, and the over all cost are frequently less.
