About Roof Dagan
Roof Dagan was founded in 1990 by Yossi Dagan. The company began with carpentry and tiled roofs, then built light-construction homes — in Kfar Adumim, Neve Dekalim in Ashkelon and Karmiel, among others — under the watchful eye of a German engineer who became Yossi’s mentor. The rigor and drive for perfection of those years have guided the company ever since.
From installing light steel structures as a subcontractor, with Yossi leading every installation himself, the company grew into a main contractor leading structural and roofing projects across Israel, with swimming-pool enclosures as its core specialty.
Good roofing starts with good planning. We work closely with architects and designers, advise from the design stage, and insist on meeting standards, precise load calculations and uncompromising safety, so that every plan becomes a flawless, high-quality and safe roof.
The company’s reputation reaches beyond Israel: Yossi Dagan advises and trains roofing and structural companies around the world, among them Polygal, Palram and SEP of Italy, and companies in Portugal, Spain, South Africa, England and Turkey.
