Dear Glenn: We live in an old farmhouse that has four different roof lines. The back end of the house was ripped off in the 1950s and rebuilt. This roof line comes into the original house perpendicular and lower to the rest of the house. There has always been a small leak somewhere in the valley of the two roofs, which in the last year has gotten to be seriously worse. We also have an occasional serious leak in our porch roof which has been converted as an extension to our living room. Can you suggest a person or company that does the water leak scan?

Betty, Ida, Mich.
