Rain and dormers | Ask The Experts Forum

Karl Waldeck 4/2/2011	Hi, I have a long stretch of steep roof (60 degree pitch) above a dormer. My concern is that rain water will be running quite quickly by the time it reaches the valley flashing of the dormer ... naturally it would curve a wide arc before running off perpendicular to it's original direction. I'm worried that water will force it's way between the valley flashing and the roofing panel overlapping it. How can I prevent leaking under the dormer panels?
