Eavestrough System Design
How We Design an Eavestrough System
A properly performing eavestrough system starts with thoughtful design. Beyond materials and appearance, correct sizing, slope, fastening, and drainage planning all play a critical role in long-term performance.
Our approach focuses on building custom eavestrough systems designed for each home, taking roof layout, water volume, grading, and downpipe placement into account.
In the Greater Toronto Area, where changing weather and heavy rain events occur, proper system design ensures water is directed safely away from foundations - reducing erosion and preventing basement moisture issues.
On-Site Fabrication
Seamless Eavestroughs Extruded to Fit Your Home
All of our eavestroughs are extruded on site to match the exact dimensions of your roofline. This eliminates unnecessary joints, improves water flow, and creates a cleaner finished appearance.
By forming each run specifically for the home, we reduce leak points and ensure consistent slope from end to end.
Corner Construction
Why We Use Mitered Corners Only
We use mitered corners exclusively. Prefabricated or strip corners introduce additional seams and are more prone to leaking over time.
Mitered corners are cut, formed, and sealed on site, resulting in fewer joints and a stronger, longer-lasting system.
Structural Reinforcement
Continuous Hangers and Secure Fastening
Proper support is critical for maintaining slope and preventing sagging. We install Alu-Rex continuous hanger systems or Quickscrew brackets to reinforce the eavestrough along its entire length.
This approach provides better load distribution, improved resistance to snow and ice, and long-term structural stability.
Water Management
Downpipe Placement and Drainage Planning
Downpipe placement is planned based on roof layout, water volume, and property grading. We always review how water exits the system and where it discharges to reduce pooling near foundations.
Where required, we recommend:
- Additional downpipes for volume control
- Upgrading from 2x3 to 3×3 or 3×4 downpipes
- Extension lengths based on grading and slope
The goal is reliable drainage without overloading the system.
Sealing & Finishing
Premium Sealants for Long-Term Performance
All joints and seams are sealed using professional-grade sealants designed to remain flexible through expansion, contraction, and freeze–thaw cycles.
This helps reduce the risk of leaks developing over time and supports long-term system reliability.
