“At this rate, Japanese architecture will stop.”
If the unit prices for roofing work do not rise, young talent will flow into other trades, veterans will retire due to aging, and eventually, there will be no one left to install roofs that protect homes. Even if people want to build houses, there will be no one to finish the roofs. This is not just a problem for one industry; it is a social issue where Japanese housing and architecture itself will come to a halt.
Hauscape Inc. (Headquarters: Tokyo; CEO: Takenori Akimasa), which develops AI SaaS such as “iesapli,” “yanePRO Homepage Service,” and “AI Color Simulation” for roofing and painting contractors, held the “Roofers Exchange Meeting by Roofers, for Roofers” in Tokyo on April 17, 2026. Business owners and craftsmen from 79 companies and 113 participants gathered from 34 prefectures, from Hokkaido to Kagoshima.
The most significant feature of this event was that specialized contractors for “tile” and “sheet metal,” which have long been treated as separate industries, sat around the same table as fellow “roofers.”
Mr. Yutaka Murata, CEO of MURATA Co., Ltd., a supporting company of this event, raised the following issue:
“If you look at the construction industry as a whole, unit prices are definitely rising due to the increase in material and labor costs. But what about roofers? With the rise in naphtha prices, raw material costs have certainly increased. In the West, the term ‘Blue Collar Billionaire’ has emerged, and we are in an era where craftsmen earn hundreds of millions. Despite this, only the unit price of roofing work in Japan remains stagnant. How to raise this is the industry's top priority.”
Despite rising raw material costs and an overall increase in economic unit prices, only roofing sites are struggling to pass on costs.
Participants commented: “I think it was truly a moment when history moved. It might be the first time tile and sheet metal workers have interacted on such a scale,” said Kazuhiro Yamazaki of Yaneyama Ichi Co., Ltd. “Sheet metal × Tile = Roofer. I reconfirmed the fact that while tools and products differ, everyone is undoubtedly a roofer,” said Shigeto Ogen of D-Trading Co., Ltd.
Background of the Event: Three Major Trends
The roofing industry is currently in the midst of three major trends: Stagnation of unit prices, the arrival of the AI era, and the Naphtha Shock. The industry is beginning to share a sense of crisis at a national level for the first time.
Trend ① Stagnation of Unit Prices: While overall construction costs have risen by approximately 35-42% compared to 2012-2015, the actual unit prices for roofing have not followed this trend.
Trend ② The Arrival of the AI Era: Potential for 'Blue Collar Billionaires.' AI is lowering the hurdles for business tasks like website creation and customer management, providing SME contractors with the 'weapons of management' previously reserved for large corporations.
