I got annul about the roof not being clean on this 73 that I'm reconditioning a few months ago. So I scrub, and power washed it. Kept getting dirt out of the channel that is between the roof, and side walls. After that time we didn't get much rain. Then as more rain moved in later. The leaks started to appear. I didn't associate the two till last week. So I caulked the area from the back of the door to the front. The leak above the door stopped. Then this morning after a night of rain. I found more small leaks. So it seems that I just rearranged some of the water contaminated dirt. So I think that it's best to do more power washing that seam. Get as much of that remaining wet dirt out. Thus reducing the future water/dirt from corroding the aluminum roof. Plus stop the frozen water from damaging the channel. Then later in the week. Calk that seam to stop further water intrusion in that channel. YES. Power washing caused me a problem. But will stop future damage. Bob Dunahugh
