Q:Roof just installed in July 2011. Had to have the roofer back to cut some shingles near the dormer that were too long and sticking up. The roof first leaked in the living room from the high hat lights and around the casement window. Roofer came and caulked around dormer window and put holes in the j channel. Then it leaked in the bedroom. I hired a home inspector for $175 who found nothing (no water or stain in attic). Roofer couldn't find anything either but home inspector said he did something little on the roof before he got up there so I don't know the whole story. Now it is leaking again from the casement window (but not the high hat). This roof was very costly and they removed all the old plywood and replaced it with new plywood. Home inspector suspects the dormer. What recourse do we have after we have three leaks and the installer cannot find the leak?

If you want to fix the leak then this may help. Often the problem with dormer window leaks is with the window sill fitting and window drain design. See my video on how to fix dormer window water leaks.
