After we got the sheathing and roof panels all cut and placed, the next step is to tape the seams and put down the roof underlayment so that it can be weatherproofed.
However before we can do that we need to make sure we add about 2600!!! screws to ensure it is properly tied down. We started but have a ways to go. On the materials front, we have loaded up with many rolls of ZIP-System flashing tape, courtesy of Volstrukt. This will cover all the seams of the sheathing and will also be used around the window frames. Putting it down in the right order so that water can always travel downward is critical.
On the recommendation from Tiny Home Builders, we also purchased heavy duty Ice and Water underlayment for the roof. Since the roof panels are more susceptible to moisture (the center roof is regular 3/4″ subfloor grade plywood as that is where the roof top deck goes) and that is often where moisture issues start. It is such a small roof after all so two rolls will easily cover it. Again, you start at the bottom and overlap each row as you go up. For us that means we start with the center section first and we will also overlap the edges (which will have the tape on them already).
So with all this, why the tarp then? Well, we got behind in applying all the screws as Robert got a bit under the weather, but more importantly, we can’t apply the Ice and Water shield below 40 Degrees Fahrenheit (+4.5 C) and it has been freezing cold. So with snow and windstorms in the forecast for today and the possibility of sleet and rain on Monday, we had to get the tarps out again. But no more cheap blue tarps (got a great deal we thought). These are heavy duty and then took a trip to Home Depot to get 300′ of rope that we used to tie it down tight.
Winds are gusting at 40 mph, the snow is coming down, the house is all wrapped up, so we will stay inside, working on all the other items that need our attention.
