Land Inspections

June 13, 2020 By Tayson Rockefeller Leave a Comment

I’m not sure if it’s how busy things are or the increase in the number of land transactions equating to an increase of things I haven’t seen before, but I sure have seen an uptick of strange inspection findings. Over the course of my career, I’ve bumped into town parcels without connectivity to a sewer line, sinkholes because of buried cars, a number of buried fuel tanks, concerns over oil spills, hillside geotechnical concerns and more. As one might expect, I’ve also run the gamut with discussions on radon, bugs, covenants and restrictions, easements and so on. However, lately, I’ve even bumped into a few more. Bedrock preventing a typical septic install, extraordinary deep wells and artesian wells and springs are a few examples. One thing is for sure (although not as geographically interesting as Yellowstone), Teton Valley has some diverse terrain with nuances that one may not normally consider. I suppose it all depends on what one might be used to in terms of the nuances of their area, but even I would not have predicted bedrock in areas of the Teton Valley.

The above being said, it’s important to do your research. Remember that as agents, we are not experts in geography, terrain, practicing law, interpreting title and so forth. Real estate agents negotiate real estate transactions, and that includes negotiating due diligence and inspection periods for buyers to better understand and research the property they intend to buy.

Unfortunately, it’s almost impossible to plan for every situation that may arise when purchasing land with plans to build. One of the benefits (although not a guarantee) of purchasing a pre-existing home is the fact that many of the potential problems either did not arise, or have been resolved. Another tip to consider when buying land is purchasing in a subdivision. Although I have bumped into properties within subdivisions that still had special wetland requirements or septic problems, it’s less likely. With the growing demand for properties that are not in a subdivision, it’s important to also consider the fact that subdivisions have likely already been through a preliminary set of county or city required engineering reports, soil testing and so on.

The moral of the story, and the theme for many of my articles is; do your research!

Cold Roofs, Explained

June 19, 2018 By Tayson Rockefeller Leave a Comment

Due to popular demand, I’m going be writing more and more articles referencing some sort of construction and my experience with it in the real estate industry. Because of this, I’m going to have a new category and page where you can find all of these construction specific articles on my website tetonrealtyblog.com – “Know Your Home”.

Recently, a past client of mine who purchased a beautiful piece of land in Snow Crest Ranch wanted to sit down with me to get my opinion on construction methods. I assumed this would be for resale value or potential rental income with respect to a layout and design, but we talked more and more about construction methods and my personal opinions there. One of the topics was cold roofs, and their importance in Teton Valley. To be clear, not all contractors, people, or Realtors believe cold roofs are a good solution, so take my advice with a grain of salt, and make sure to consult with your architect and/or contractor.

First, what is a cold roof? A cold roof is basically a roof in which the insulation is above the ceiling of the home, but there is an air space between the insulation and the roof itself which is not conditioned or heated space. In most cases, this space is also ventilated to allow airflow between the insulation and the roof.

The primary purpose of a cold roof, particularly in our climate, is to prevent ice dams. Because most of the heat inside your home rises and “stacks” along the highest points of the ceilings, much of that heat and the moisture in the air along with that heat finds its way through the roof and into the attic space. Most people don’t realize that even latex paint is not a vapor barrier, it will allow moisture and heat to convect through the drywall and the insulation. If this heat doesn’t have a way to escape before it gets to the bottom of the roof opposite the snow sitting on that roof, it will eventually melt the snow. As the snow melts, that water turns to ice which creates ice dams, those gigantic icicles hanging from your roof eaves. Once this begins to happen, ice can freeze up and under flashing, and creep into areas it’s not supposed to be, often causing leaks on the inside of your home. There are other benefits to a cold roof, such as ventilation. As I had mentioned above, often times that warm air carries some of the moisture inside the home along with it. These ventilated spaces between the insulation and the roof allow this humid air to dissipate.

Depending on the style of construction, cold roofs are easier to achieve with some types of roof systems than others. For example, if you are planning on flat ceilings with vaulted ridgelines, you’ve got plenty of space for an unconditioned attic, adding vents in the soffits and along the ridge is an easy task. However, you might be building a shed style roof or perhaps your ceilings are vaulted inside to match the roof lines. In these cases, it can be difficult to achieve the required R-value if you reduce the thickness of the insulation to allow space for ventilation. One consideration here would be to use closed cell spray foam which has a higher R-value per inch. If you do this, make sure you work closely with your contractor and insulator to make sure that the foam is thick enough and the proper vapor barriers are in place as not to cause condensation problems.

Will Heat Pumps Work in the Teton Valley Climate

April 18, 2018 By Tayson Rockefeller Leave a Comment

You’ll probably find a video in the coming weeks with respect to heat pumps in our climate, I’ve just installed one. One can assume that probably means that they do work in our climate, otherwise I wouldn’t have installed one. The real answer is, pretty much. With that said, read on for details.

The first thing to understand about heat pumps is how they work. In a traditional sense, heat is created by burning fuel (in the case of Teton Valley, propane, whereas natural gas is not available) or with the use of an electric heating element much the heating element in your oven, or the elements that glow bright red in your toaster. Heat pumps work much differently. Essentially, they absorb heat from the outside and transfer that heat inside your home through refrigerant. Refrigerant has all sorts of weird properties that allow it to boil and change from a liquid to a vapor at temperatures far different than something like water.

Not all heat pumps are created equal, there are different types. The most common types are air source and ground or water source heat pumps.

Ground source heat pumps are more traditionally referred to as geothermal systems. There are different types of geothermal systems. The most common types are open-loop and closed-loop, we see closed loop systems more frequently in our area, but I have seen both. With a closed loop system, liquid is pumped through tubes in the ground which is naturally warm, even throughout the winter months. The heat that is absorbed is then extracted from the liquid as it returns to the heat pump, and the cold water is then pumped back into the ground to be reheated naturally. In the case of an open loop system, groundwater is used usually from a domestic well, the heat is extracted, and the water is then allowed to drain or in some cases is injected back into the ground.

Air source heat pumps are more traditionally referred to as condensers and evaporators, a good example is an air conditioning system. An air conditioner works by absorbing heat inside the home, then transferring it outside. In the winter the cycle reverses, and the heat is absorbed from the outside air and transferred inside. Believe it or not, there’s enough heat in the outdoor air even at very low temperatures. Obviously a major benefit of an air source system is that it can be reversed, and the home is then air-conditioned during the cooling months. The downside is that these systems begin to lose efficiency at about 0 degrees Fahrenheit, but can operate efficiently in Sub-Zero temperatures to a point. This is why at the preface of my article I said “pretty much.”

With respect to the air source systems, it never gets below 0 degrees in Teton Valley, so there’s nothing to worry about. Right? Sarcasm aside, there are solutions. The easiest solution is obviously a backup heat source that can be activated when the temperatures get too low for the system to operate efficiently. The other solution is to add an auxiliary form of heat to the system which can either be in electric coil that is activated at very low temperatures, or a gas furnace that activates at low temperatures. The latter is referred to a “dual fuel” system.

There are other types of air source heat pumps which are commonly referred to as “mini splits.” Mini splits are basically an air source heat pump, but rather than having the system tied to a traditional furnace, they usually have a smaller self contained blower connected to an outside condenser via refrigerant lines. Mini splits are very common in most parts of the world because of their efficient cooling and heating capabilities and the fact that they can easily be retrofitted to any residence or building with relative ease. The downside is that most mini split indoor units (often called heads) don’t have any way to add auxiliary forms of heat such as heating elements or gas-burning forms of backup heat. Regardless, I do anticipate seeing more of these types of installations with backup heat such as baseboard electric which can be used seldomly when the temperatures dip into the sub double digits.

As for my system, it’s ducted and ductless mini split system with backup heat strips and temperature lockouts, all of which is controlled from my smartphone. I’d be happy to fill you in, it’s pretty cool stuff.
