How much does it cost to add drip-edge flashing behind new eavestroughs in Ottawa?

Adding drip-edge flashing behind new eavestroughs in Ottawa typically costs $3 to $8 per linear foot when included as part of a complete eavestrough installation project. For a typical Ottawa bungalow with 120 to 150 linear feet of roofline, expect to pay an additional $400 to $1,200 for drip-edge installation alongside your new eavestrough system.

Understanding Drip-Edge Flashing in Ottawa's Climate

Drip-edge flashing is a crucial component that many Ottawa homeowners overlook, but it's especially important in our extreme climate. This L-shaped metal strip installs under the first course of shingles and extends over the fascia board, creating a barrier that directs water into the eavestrough rather than behind it. In Ottawa's freeze-thaw cycles, water that gets behind eavestroughs can freeze, expand, and cause significant fascia damage over time. The 50-plus freeze-thaw cycles we experience each winter make proper water management absolutely critical.

The flashing material itself costs $2 to $4 per linear foot, with aluminum being the most common choice to match aluminum eavestroughs. Copper drip-edge runs $6 to $12 per linear foot and is typically used with copper eavestrough systems on heritage homes in areas like Rockcliffe Park or New Edinburgh. Installation labor adds another $1 to $4 per linear foot, depending on roof complexity and whether shingle lifting is required.

Most Ottawa eavestrough contractors will install drip-edge as part of a complete system replacement, and this is the most cost-effective approach. If you're adding drip-edge to existing eavestroughs, expect higher labor costs of $5 to $12 per linear foot because the work requires careful shingle manipulation and potential re-sealing. On steep roofs or complex rooflines common in Ottawa's older neighborhoods, installation becomes more challenging and expensive.

The Ontario Building Code doesn't specifically mandate drip-edge flashing, but it's considered best practice and many Ottawa contractors include it automatically in quality installations. Homes without drip-edge are more susceptible to ice dam damage, fascia rot, and water infiltration behind the eavestrough system. Given Ottawa's harsh winters and heavy snow loading, the investment in drip-edge flashing typically pays for itself by preventing costly fascia repairs down the road.

When planning your eavestrough project, discuss drip-edge installation upfront with contractors. Quality installers will recommend it, especially if your existing fascia shows signs of water damage or if you're upgrading from an older system that lacked proper flashing.
