The Challenges

The extension required careful integration with the existing roof — matching tile lines, getting the falls right on the flat section, and detailing the dormer cheeks in matching plain tile to keep it looking like part of the original house rather than a bolt-on addition.

The Result

A clean, well-integrated extension roof — plain tile dormer, Velux windows for natural light, dry ridge, and a properly detailed flat roof section. Covered by our full IKON Integrity Guarantee: 15 years on workmanship, 15 years on materials, and 10 years insurance-backed protection.
