To achieve a gutter flashing installation that will keep water from draining from your rain gutters and onto your house, there are certain mistakes you will need to avoid making.
Fastening Your Gutter Flashing to Rotten Fascia and Soffit
Fascia and Soffit that you will be attaching your gutter flashing to can, in time, rot from weather. Nails or screws you use to attach your gutter flashing to these rotten surfaces will not hold, and your gutter will soon become detached and will allow drain water to run down the walls of your house.
Fastening Your Gutter Flashing to Uneven Surfaces
Never fasten your flashing to uneven surfaces. This will result in leaking flashings. Crown molding or trim board attached to your home's fascia should be removed from surfaces where you plan to attach your flashing.
Splicing Gutter Flashing Sections
In splicing gutter flashing sections, never lap the downhill end of your flashing over the uphill section. Doing so will allow water to drain down the flashing and run under the flashing.
Assembling Gutter Sections while Working on a Roof
When assembling gutter section do this work on the ground; not on the roof. Assembling these pieces while you are on the roof will cost you time and possible addition expense from mistakes you make.
