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.

Everything You Need to Know About Snowbirds

I noticed we don’t have any information about snowbirds on our website. Since we just had about 16″ of snow this seams to be a relevant topic. Why do we need snowbirds? After it snows 6″ or more metal roofs will generally release the snow in a sheet of ice on the first sunny day and anything under this avalanche is in jeopardy.
If there were more snow it generally slides off in one huge mass. There are two styles of snowbirds pictured below.

Both the red and green snowbirds are powder coated the color of the roof metal. Painted snowbirds only take a few snows before the freezing action of the snow pulls all of the paint off. The snowbird on the right is made of bronze and used on copper roofs. All these snowbirds are attached with two set screws on the standing seam metal roof so as to not penetrate or mar the metal or paint.
