We've been told we need to do a metal roof valley and we have no idea what that means nor how to do it. Has anyone ever needed to do that before and how much did it cost or how long did it take?

Make sure you order order unformed panels as flashing and try to get 4x10 sheets so you can put it in the metal valley break. Use it at the pitch breaks. You can also use valley pans and hip/ridge covers that can be handled with a transition and Z metal and the valleys are easy. description

All you have to do is lay a metal valley flashing panel in the roof valley at the bottom eave. Drive a screw into the bottom corner. Lay the next flashing panel near the roof ridge, overlapping the first panel about four inches. Drive another screw in. Keep doing that until you get to the roof ridge. Trim the final valley flashing panel to fit (when necessary) using the tin snips. description

You can get them fabricated per the type you need because valleys are part of well designed roofing systems. In metal roofing, valley flashing adds detail and helps to direct water so alot of the time its fabricated in many different profiles. For example, in metal roofing systems, valleys are commonly fabricated with hems. Valley flashings can be customized to any measurements and angle. description

We did it and it was very easy and we don't think anything's easy to do like this. There are two types of valleys. There is open and close. On the open valleys you have the valley line covered by a valley component, not the primary roofing panel system. A layer of high temperature ice and water shield covers the wood decking at the center of the valley. You put a special underlayment made for metal roofs over the ice and water barrier with a W or V shpaed piece of metal that's the valley component, is installed on top of the underlayments. The closed valley are either “woven” together with the shingles, or they are cut and meet to form a straight line down the center. Most metal roofs is open. description

By using metal flashing for your metal valleys you eliminate any metal valley issues like debris collection, improperly lined shingles, faulty underlayment, and problems with cascading water flowing across the valley. You can use flashing when you're afraid there will be moisture penetrate the roof between joints. Its the flashing that helps create an impermeable seal. description
