The Headline Number, in Dollar Terms
Roughly 80% of roofing industry activity now comes from renovation and re-roofing work rather than new construction, according to IBISWorld, a figure that same research source flags as drawn from search synthesis rather than a directly re-verified live page. Applied to IBISWorld’s own $92.5 billion 2026 US roofing contractors market figure, that 80% share works out to approximately $74 billion in renovation and re-roofing activity, against roughly $18.5 billion in new-construction roofing. That dollar split is this page’s own calculation, applying a published percentage to a published total; it is not a separately reported figure, and it should be read as an estimate built from two real numbers rather than a third sourced statistic.
Framed in dollars rather than a bare percentage, the number is easier to act on: renovation and re-roofing work is not a slightly larger slice of a roofing company’s pipeline, it is close to four out of every five dollars moving through the industry.
What the Available Data Does Not Break Out
The 80% figure is a single national number, not a regional or segment-level breakdown. No source located while researching this page splits that renovation share by state, by property type, or by whether the re-roofing job was storm-driven, insurance-funded, or a voluntary retail replacement. A market with 108,598 active roofing contractor businesses, growing 2.6% year over year inside a market expanding at a 5.0% compound annual rate since 2021, is clearly large enough to support a deeper breakdown, but the sourcing to publish one responsibly was not available at the time of this research.
Treat the 80/20 split as directionally reliable, since it is corroborated by how consistently the roofing industry’s own literature describes renovation as the dominant driver of demand, and treat any more granular regional claim about that same split with real skepticism until a source publishes it directly.
The Numbers
Roughly 80% of roofing industry activity now comes from renovation and re-roofing work rather than new construction.
Applying that 80% share to IBISWorld’s $92.5 billion 2026 market-size figure works out to approximately $74 billion in renovation and re-roofing activity versus roughly $18.5 billion in new-construction roofing (this page’s own calculation from two published IBISWorld figures).
108,598 roofing contractor businesses were active in the US as of 2026, up 2.6% year over year, the business base serving both sides of the new-versus-renovation split.
