A roof's lifespan depends on material, maintenance history, and environmental conditions. Our calculator estimates your roof's remaining useful life based on this information and tells you when renovation will likely become necessary.
How does the lifecycle calculator work?
Enter your roof's material, age, area, and maintenance history. The calculator compares this data against known material lifecycle figures and estimates the remaining useful life.
The calculator also considers environmental conditions: proximity to the sea, tree shading, and local weather conditions affect roof wear.

When does roof renovation become necessary?
If the calculator shows your roof's lifespan is nearing its end, it's time to consider renovation. A condition assessment provides an accurate picture of the roof's actual condition and helps plan the renovation timeline and budget.
