I noticed the other day when we had a big rain, run-off from the roof was going over the gutter. This weekend I took a look at that section of the gutter and noticed the shingles are kind of bending upward - almost like a ramp for the water to fly over the gutter. I also noticed the flashing was lifting up at this spot - appearantly pushing the shingles upward. I slightly lifted the singles and noticed that where the flashing comes up, there are no nails/screws holding the flashing down. If I could get the shingles lifted up high enough, it looks like I could simply screw down the flashing. Yet, the singles don't lift very high - so I don't think I can get a screw driver in there without removing the singles - which I have not done before. Can anyone offer a suggestion how to fix this - easily? Two pictures at In Box Photo Gallery by Dave Hilbe at pbase.com. Thanks in advance.
