In the vast majority of cases, gutters are installed directly to the fascia board using screws or nails. But, what if there is no fascia board to install the gutter to? What if there is a crown molding instead? In this case most gutter installers will choose to install the gutter to the roof using Strap hangers or hanging rods.
The problem with this strap hanging system is that contractors almost always do a poor job installing them. What do I mean by a poor job? Here is a picture I took of a gutter hanging from my roof.
The nails holding the hanging rods are nailed right through the roof with the heads left exposed to the elements. When a nail head is exposed, water can follow that nail down into the wood. This water can cause rot and mold. These nails should at the very least be caulked in to prevent leaks.
The best way to install these hangers is by securing them under the shingle and not on top. To illustrate, I gently pulled up a shingle tab and installed a hanging strap.
I used two deck screws to secure this strap into the roof. Now this strap can hold a gutter while being safely hidden under the roof. No more exposed nails.
Thanks for reading my post.
