The best gutter cover in New England, Maine

Valley Water Collection

Large modern homes with large roof valleys can generate large volumes of rainwater that can overwhelm even oversized gutters. 

This water needs to be controlled so it doesn't overshoot the gutter and cause problems on the ground below and in the basement.  Adding  gutter covers can compound the problem making it harder to rectify unless your gutter protection system comes with a patented solution that not only can control the water but also makes it easier to keep the valley clean.

Since our beginning in 1989 we recognized that valley water presented a challenge to any gutter guard system that  wanted to collect all the rainwater.  We experimented with many different possible solutions including splash blocks, corner screens and openings in the top of the inside corner panels none of which worked to our satisfaction. 

The combination of a low solid diverter and overlapping perforated diverters worked the best but was not perfect because in some situations debris would behind it and can be difficult to keep clean.  Feedback from customers and installers lead to the development and patenting of  the Valley Fall panel and the Dome Diverter.

Three ways to control roof valley water

Valley-Fall valley collection panel.
Valley-Fall™ - We especially recommend this award winning and patented solution for high debris collecting valleys.  The panel is interweaved with the roofing and features a design that doesn't contribute to the collection of debris.
Dome Diverter controls water in smaller shorter valleys.
Dome Diverter - Use for smaller shorter valleys. We call it a Stealth Diverter™. Recommended for short valleys that tend to have debris laying in them.
Fence Diverter for moderate valleys that don't hold debris.
Fence Diverter - Unlike the old solid splash block design, Waterloov's® diverters have openings that can be regulated in size to allow distribution of water along the louvered section of the water collectors. Only recommended for low debris collecting valleys.
