The black you see is carbon. An excessively large flame will produce carbon due to lack of sufficient oxygen from the air in the jar to provide complete combustion. The updraft of hot gases from combustion hinders diffusion of air into the jar and that starves the flame of oxygen. The key for that perfect burning candle is wick maintenance. The wick must be trimmed to no more than 1/4" throughout the candle life. The candle can be burned for several hours without trimming.

Roofs leak from a break in the waterproofing layer, sometimes caused by mechanical damage (ie, someone dropping an HVAC access panel on the roof), sometimes from an opening in the sealant, such as pitch pans and caulking, and sometimes from deterioration or defects in the roofing material. The key roof management task is leak avoidance. Find and correct defects before they leak.
