In our last post, we shared our first version of a cool roof ventilation system that automatically vented the hot air through a custom vented ridge vent and replaced it with cooler air through a custom eave vent.

The photo below shows our latest improvement that not reduced the labor cost but also introduced a thermal break as well as a radiant barrier. This latest improvement not only addresses all 3 ways heat is transferred, it works on any roof style including asphalt shingles.

Our first attempt at installing a roof ventilation system worked great but was very expensive and labor intensive. As you can see this prototype started with a bubble foil bubble insulator and then a cumbersome wooden counter batten system Even though it really cooled the interior of this historic renovation on this converted barn it was labor intensive and expensive.

In our next post we will share with you our next step in the development of our roof ventilation system.

We are installing an under roof ventilation system with a standing seam metal roof on an older farmhouse in Culpeper VA from the early 1900s.

I recorded a video on-site that I have put a link to below.  I show in the video the under roof ventilation system before the metal roof has been installed, and how we are able to allow the air to flow through the drip edge that we custom make on the job site.  The ventilation panels are about the size of a sheet of plywood and go down on top of a radiant barrier that we install first over the roof deck or skip sheathing.  The Ventilation panels are called Therma-Vent.  These panels allow for the roof to vent air through channels that run vertically up the panels and then the air escapes through a vented ridge cap.

Please take a look at our video and below and contact us for more information about metal roofing and our under roof ventilation system.

Alpha Rain has developed a new innovative Energy Efficient Roof Ventilation System for Metal Roofs in Va, we are putting this patented roof on many homes in the Charlottesville VA area.

There are 3 ways to transmit heat:
• Direct heat transfer-think of a tea kettle on an open flame
• Convective heat transfer- think of a turkey in an oven where the hot air cooks the turkey
• Radiant heat transfer- think of popcorn in a microwave

Our new Radiant Therma Vent roofing system addresses all three. The Radiant Therma Vent panel acts as a thermal break to stop the direct heat transfer. The air ventilation we introduce into the radiant Thema Vent system stops the convective heat transfer by ventilating the hot air out of the ridge and pulling in the cool air from the eave area. This system even vents the hot air from the attic. The use of a Radiant barrier stops the radiant heat transfer. This radiant barrier is so intelligent that in the winter it stops the radiant heat from leaving your house!

This system is only available from Alpha Rain, your metal roof specialist. We will be happy to show you a prototype of this system and actually take apart a portable mock up of a section of roof. We will also show you on a digital photo what your home will look like with a metal roofing. We can even show you different roof colors so you won’t be guessing what color will look best.

Radiant Therma Vent

Metal Roofing VA introduces ventilation to the roof and attic. It reflects radiant heat with the use of a radiant barrier and it stops the conduction of heat in the summer and cold in the winter into the attic space.

How it works: the drip edge at the lower edge of the roof has an air gap below it where air can enter. As the air under the roof is heated by the sun, and as hot air rises exiting the vented ridge vent then cooler air is drawn in at the eave. As long as hot air rises (we don’t think a law can be passed to stop that) then this becomes an automatic air ventilation machine. There is a Styrofoam panel with grooves in it to enhance the air movement and to create a thermal break where cold or heat cannot be conducted into the house.

The home above is located in Charlottesville, Virginia and you can see how the panels are being installed right on top of the foam panel. The radiant barrier is under the panel and the air pathway is under the panel as well.

We will be happy to show you a prototype of this system where we actually disassemble a model of this unique but effective approach to ventilating older homes.

Metal Roofing Ventilation Charlottesville VA

This is a two-part blog about metal roof ventilation system for Charlottesville VA.  One thing that I have noticed is that not too many contractors or roofers understanding the importance of ventilation for attics or for roofing systems.  In this part, on the blog, I’m going to focus on ventilation in the attic.  Have you ever wondered why some attics are a lot hotter than others in the summer?  Most of this is due to poor ventilation if you have ridge vents in your roof which allows a way for the hot air in the attic to escape, but no way for the air to enter at the bottom of your attic you are doing a disservice to yourself.  For air to escape you must have a new way for air to enter, Hot air always rises, so as the hot air heats up and rises you need a way for the fresh cooler air to enter.  The proper way for this is through a soffit vent or through our custom metal roof vent which is placed at the bottom of the roof when the roof is installed.  Our custom metal roof entry even allows for fresh air to enter below the metal roof and flow into your attic.  This is very important to many old houses that do not have any soffits or way to vent air into their attics from the bottom of the roof area.  We have made a video what I have linked to it below that shows a sample and that I will explain exactly how this process works.  In Part two I will talk about Vented J Channel and how we installed a complete patented roof ventilation system in addition to venting the attic.
