The other day I watched an insurance adjuster evaluating a roof for hail damage and noticed that he didn’t whip out a tape measure to record the roof dimensions — instead he used a little measuring wheel like the Keson RoadRunner model 182.  Keson designed this dual-wheel measuring wheel primarily for measuring short indoor distances, but why the heck not use it on a dry roof?

Keson claims that, with their measuring wheel, you can take a measurement by yourself faster than two people with a tape measure. The dual wheels provide greater stability and make it easier to measure in a straight line, but you can also measure curved, horizontal, and asymmetrical surfaces. The small one-foot wheel’s compact size and its 2lb weight make it easy to carry, which perhaps is why Keson claims it’s so popular with realtors and appraisers.

They accurately mold the dual wheels from solid rubber, and the handle extends from its storage position to 38″.  The five-digit magnified counter measures up to 9,999′ 11″ and resets with the push of a button.  Rolling backwards also subtracts from your counter.

The RR182 two-wheel measuring wheel runs about $40 to $45.  If you can tolerate measurements in tenths of feet instead of inches, you can pick up its less popular brother for cheaper.

    Why not? Because it’s one more thing to have to carry up and down the ladder. Then, if you have a pitch greater than 6/12, it would probably roll right off the roof and wind up busted on the ground. If you tether it to your waist, it would probably drag along the roof, possibly doing more damage.

    When I adjusted hail claims I took most measurements from the ground and calculated the roof area based on the slope of the roof.

    The only thing I used a tape for was to mark off a few 1-square areas so I could get a representative sample of the damage.

    FYI, after the huge hailstorm in Madison, WI (4.75″ hailstones), I adjusted 100 roofs. Only one was damaged to the point it would need replacement. It’s pretty rare for a roof to actually be damaged to that point.

    For that sloped roof – you might try a tape dolly:
