Is there a building code on deck board spacing?
I have a flat roof and my contractor built a cedar board floating deck. the area is 16’x20′ range and he made into 4 section, 16’x5′ each. the boards are tight fit(no space) and also tight fit to the edge wood board( the wood board sit on top is metal capping). the nails are all sunken under the wood surface. One winter with snow/rain, I had to shelve the snow off the roof since the ice/water sit on the cedar boards. there was a leak(this roof did not have leak before the new deck). I tried to find out where the leak was, but the boards were all frozen together, like a big ice block. Everyone I know said it is built wrong–should have space. and my roofer refuse to touch to avoid any claim. my builder insist he did it properly. I do not know what to do. the contractor finally came to break the edge of board from edge of roof wood and remove 2 sections. but insist what he did is totally correct. the fact I am unable to remove the deck is my problem, not his. I find this attitude wrong. but there does not seem to be any code of construction.
is there any association or building code for deck? any bureau for me to call who really can offer professional opinion?
