New siding over t1 11.

Inspect the t1 11 siding carefully. T1 11 was a bad idea in damp climates for a number of reasons. It has a flat roof and no overhang. I have been reading various opinions on this topic and hope to generate some conclusion on what is the right choice.

1 should i include a moisture barrier over the existing felt for the front of the home prior to hardiplank install. The roof has virtually no pitch. Overall the versatility of t1 11 makes it a great building material to work with. More than 50 years.

I have a house with t1 11 as it s siding sheathing. The actual question is should the current siding be removed with osb installed or should the current siding remain to act as a substrate an additional layer beneath the top layer under the new hardieplank siding. Siding serves a number of important aspects so picking the correct one for your new shed is essential. Nor can you overlay compromised t1 11 with a non structural panel and assume that it still meets the structural requirements.

2 should i add a moisture barrier over the existing t111 siding for the other three sides of the home. That in my mind anyway raises the question of whether to apply a second layer of building paper under the shingles or to just shingle directly over the plywood. Hardie panels are not structural you can t just replace one with the other. Something you will want to keep in mind when making this decision is how long hardieplank will be on your home.

I want to put horizontal and vertical siding over the t1 11 with some wrb and coraplast strips behind it. But would the double layer of building paper tend to trap moisture in the t1 11. T1 11 siding is usually the structural sheathing not merely siding. Overlay of hardie plank siding over plywood t1 11 some arizona houses were built with wood siding normally called t1 11.

My inclination is to do the former apply a layer of building paper under the new shingles or siding. The facia has vents drilled in it currently. Though t1 11 siding is durable and improves the support of the structure it requires much more maintenance and needs to get refinished with stain every 3 to 5 years. Bought in big sheets 4 8 or 4 12 these sheets can cover lots of sf very easily.

In this case would you recommend eliminating the vents.
