Roof Sheathing & House "Wrap-up"

This weekend I finished fastening the sheathing to the roof (doing much better with heights now!) and Dad and I completed the house wrap. I chose Hydro Gap from Benjamin Obdyke, which is a “drainable” housewrap. It has little spacers on the surface to allow water that gets behind your siding to drain out. Sort of a mini rain-screen.

Useful tip: A belt sander with 36 grit sandpaper comes in real handy when you need to shave down the edge of a piece of plywood by 1/16”-1/8”. Just mark your cut line and grind away! The results are much cleaner than what you get from a circular saw.

Much could be written about each of these steps, but I’m tired… so here’s a bunch of pictures instead! That’s what everyone really wants to see anyway, right?

    Some great new photos, Mike!

    I would just like to add that applying house wrap is absolutely, unquestionably and totally necessarily a more-than-one-person task - even when you are unrolling the wrap horizontally at the lowest level, where one of you can be standing on the ground while doing the job! The full roll - I think it was 100 feet long and 5 feet wide - is pretty heavy when you first start, and one of us (I) had to be the roll supporting and unrolling guy; while the other, Michael, monitored the horizontal alignment and tacked in the staples at two-foot intervals.

    It proved helpful to put staples in only along the top edge of the wrap at first - then to come back later and finish stapling at bottom and other levels.

    The wrap material tended to form ripples in places, which we generally smoothed out by adjusting the height of the roll itself as we advanced and applying moderate tension to the unrolled material before stapling it. Where the wrap material passed over an opening and there was no sheathing directly under its top edge, the wrap seemed to want to "billow" either into or away from the opening - even with some tension applied. We didn't fret much about this, as that material will be cut away (if the windows ever get here) before long.

    The practice we got by covering the lowest five vertical feet of sheathing all around the house with only one of us (the stapling guy, Mike) on a ladder was invaluable when it came to wrapping the next five-foot-high strip just above and overlapping it.

    For that next level, both of us had to be on ladders. We happen to have a very unwieldy, super heavy and ancient wooden stepladder about 7 or 8 feet tall; and it worked out that I, still the unroller - could rest most of the weight of the heavy roll either directly on the top of the stepladder or use the top to brace my left elbow while supporting the roll against the sheathing with my left hand. We progressed around the house in about two-foot intervals - moving first my ladder (while Mike stood on his ladder and held the roll temporarily for me) and then following with his ladder after he passed me the roll again in my new position. We got to be fairly proficient at this repeated routine. Had I not had the top of the stepladder to rest weight on, the job would have been much more awkward and exhausting. I never thought I would ever really appreciate that monstrous old stepladder!
