Ladders in the Roof!

Yes... 'IN' the Roof...

Ever wonder how they build those overhanging parts of roofs. Well they do it with something called a roof 'ladder'.

The ladder for the front gable is illustrated in the picture. How this works is that the gable truss - that is the one at the very end - is actually shorter than its sister trusses. The ladder sits on top of this gable truss and hangs over - or cantilevered in building lingo. The opposite side of the ladder is nailed to the second truss, and voila! you have the roof overhang.

There are two gabled ends on the cottage. The second one is around the side.

BTW - My trusses were manufactured by Kent Trusses based out of Sundridge Ontario.

Just curious, why did you decide on trusses instead of stick building the roof? Most builder prefer to stick build because it is cheaper, and usually is only a little more time consuming...

I believe in this case the trusses were a much faster means to get the roof built. The roof is a complex roof - I can't imagine doing all the calculations to do it by stick building, plus this way it gets designed and built by a professional - I just had to assemble it. If it was a simple roof Yes I would have built it stick-wise. As it stands this roof has 2 dormers, and a 16 foot 8-sided gasebo - very complex...

Cost wise it was perhaps about 50% more cost in terms of materials but saved a tremendous amount of time. Assembling the trusses took about 3 long days with my sons helping, I can only guess that building it by stick would have been at least twice as long. The trusses cost me about $3750 - buying the lumber and all the stuff to put it together would have been about $2000. The extra cost was well worth it in time savings and peace of mind.
