Attention to detail
At Sustainable Energy Services (SES), we believe the quality of an installation is defined by the details.
On this project, we installed a premium in-roof solar PV system using a traditional lead flashing kit, rather than the commonly supplied Flexalu plastic flashing system.
While Flexalu can provide a weatherproof solution when installed correctly, we chose a lead flashing detail to deliver a cleaner finish, greater durability and a more robust long-term installation.
Why We Chose Lead Flashing
Unlike plastic Flexalu skirts, lead flashing provides:
- Superior weather protection and water management
- A cleaner, more traditional roof finish
- Increased durability with a significantly longer service life
- Better resistance to UV degradation and temperature changes
- Improved integration with the existing roof covering
- A higher-quality appearance that complements the property
Attention to Detail
Our installation team carefully dressed and integrated the lead flashing into the roof, ensuring every detail met our own high standards—not just the minimum manufacturer requirements.
The result is an installation that not only performs efficiently but also enhances the appearance of the property while providing long-term confidence in the roof’s weatherproofing.
Why It Matters
Solar PV systems are expected to perform for 25 years or more. The quality of the roof detailing is therefore just as important as the quality of the panels themselves.
By investing in premium installation methods, SES delivers systems designed for longevity, reliability and exceptional workmanship.
