I hit my limits today, kind of bummed about it. I have all week off so I've been energetic about getting some things done around the house. It was a nice day in the 50's so I thought I might go check the chimney cap and clean if necessary. I clean from the bottom up with a SootEater and haven't checked the cap for a long time. So I get the ladder out and climb on the lower part above the garage and go to the ridge and that's where the fun ended. I climbed on the second part of the roof to get to the ridge but the gravel on the shingles was so loose I just slid. No traction what so ever. Scared the crap out of me. I crawled back down to the lower part and got off the roof. The roof is 8/12 pitch, two story about 30 off the ground. The shingles on the roof aren't that old maybe 6 years but the gravel sure is loose. Any way that's my story.
