A few quick taps: what your garage needs, what the roof and door cost, and the order to do it in. Contact details come last, and only if you want a price.
A single garage, new roof and a roller door: €3,120 to €6,300, the old door taken away included.
How the estimate is worked out
Roof and door ranges are what Irish roofers and door companies publish for the same job: the lowest to the highest figure. A double garage roof is its area times the rate for the covering. Floors, walls, windows, insulation and electrics vary too much from garage to garage to price fairly without seeing them, so the builder prices those on a visit.
