Built-In Gutter Systems |Precision Gutters Ltd | Vancouver BC
Built-in Gutters, sometimes called Hidden Gutters, are a gutter system formed by the structure at the eaves of the roof. Rather than attaching an external gutter to the outside of the fascia, a Built-In Gutter design uses the board to frame in a trough to collect rainwater at the roof edge. This requires a waterproof membrane placed over the board and under the roofing material some distance up the roof slope, depending on the pitch. A Cap Flashing is attached to the top of the board to protect and provide a finish, while a copper pipe soldered to a flange is used to drain water to a downpipe.
For residential homes, Built-in or Hidden Gutters were introduced primarily as a feature for enhancing architectural appeal. Common issues experienced with this type of system are; poor sloping, inadequate capacity and small drains mounted too high on the slope. As the gutter is “Built-In” to the building structure, any leaks cause wet boards and structural damage. The workmanship is of primary importance with proper bonding of seams and sealing between different materials.
Lifetime expectations vary greatly, depending on materials used and the quality of the installation. As the visible portion of the gutter is exposed to weather extremes and direct sun, the membrane expands and contracts and can fail at incorrectly installed seams and outlets.
If your home uses a built-in gutter, our best advice is to have a professional clean and inspect them for performance, before expensive wood repairs are needed. Drips can be obvious, however dark areas of wood at the fascia boards and staining or discolouration of the soffits are telltale signs of water ingress. Keep in mind that weather and temperature play a part when repairs can be undertaken, so don’t leave a problem to grow through the next winter.
