Asphalt shingles need to be replaced, depending on climate and other factors that cause them to degrade, every 10(?) to 20 years.
Thus at least 5% of the total roofing market in existing residential houses, is a potential customer each year.
- majewsky 10y agoAssuming that everyone uses asphalt shingles, which is definitely not the case. For example, the German Wikipedia article for asphalt shingles describes them as "a typical GDR roofing". Germans tend to prefer clay/ceramic tiles on their homes, which can easily last 50 years and more.
- patrickg_zill 10y agoThe asphalt shingles are very popular in the USA, which is what I assumed their first market would be, since contractors apparently have to be trained in their installation.
- majewsky 10y agoThat seems likely. I just wanted to point out that the market looks quite different in other countries.
