FIRE on my fence

At 3AM, there was a loud knocking on my door. I was thinking, something weird was going on. I was careful to answer the door. The knocking was strange and powerful. I got up and approached the front door quietly, but while I walked up, I saw an orange bright flickering light out of the window. A fire! A 9-11 call. Put on pants (I just couldn’t run outside in boxers), put cat in bag, go to the backyard and turn on the hose and spray the roof next to the fence. I sprayed and sprayed until I heard the fire engines arrive. The fire was growing despite my efforts. I saw flames and embers flying up towards the roof.
