There is no logical reason not to have house wrap under vinyl siding, and many authorities strongly agree that it should be viewed as mandatory, even if your local building codes don’t necessarily require it. Another benefit of quality vinyl siding is that it is highly water-resistant when correctly installed.

Then, Do you have to replace house wrap when replacing siding?

There is no problem with applying a new layer of housewrap over the old. In fact, it’s recommended. Aside from the likelihood that there have been advances in the housewrap membrane itself over the last 23 years, you can‘t be sure how long the existing housewrap was left exposed to the sun before siding was installed.

Considering this, How do you fasten Tyvek? To install Tyvek, start by positioning a roll at the first stud on the outside wall, leaving a 12 inch overlap around the corner of the house. Then, unroll the Tyvek and secure it with nails every 12 inches along each stud.

Do you need a vapor barrier under a metal roof?

Traditionally, we‘ve insulated the roof panel to try and keep the temperature on the panel FROM reaching the dew point. We‘ll add a vapor barrier so the moist air does not flow up through the insulation and condense on the roof. But a preinstalled membrane may be even more effective at removing condensation.
