What the heck is “soffit” and what kind do I need?
To put it simply soffit is the covering of the overhang from your roof. Walk out your front door at look straight up that is your soffit.
There are three common soffit types Wood(not much anymore), Aluminium (still very common), and Vinyl. Since this is a vinyl siding site we will explore some of the different vinyl soffits on the market their styles etc. Additionally, we will talk about the right and wrong ways to install soffit and give you our recommendations. Most all vinyl siding manufacturers offer a matching soffit system to complement. Some even offer color matched coil stock for trimming or making gutters to complement.

Vented or Non-Ventilated Soffit Panels – What you need and what to watch out for.
Most homeowners will want to purchase continuous vented soffit panels in order to reach the recommended roofing ventilation standards required by most manufactures for airflow. This is one of the most important things to consider especially if you live in cold climates and get ice dams or the such. The most common existing soffit was either wood or aluminium and are often grossly inadequate for total ventilation. Many times you will see aluminum soffit panels in the common 3:1 ratio which was three solid panels and one ventilated(basically holes). We don’t think this is a good idea and highly recommend continuous ventilation products. You will see below some different styles of which our top recommendation is the hidden ventilation panels for looks and performance.
***A quick note about upgrading from wood soffits to vinyl soffits. One common mistake that is made is to simply cover the wood with vinyl, however this blocks to ventilation in all areas excepts where there were pre-existing vents. Even cutting holes every so often is usually inadequate. Bite the bullet now and just rip them out, you will be happier in the long run. OK on the some types of vinyl soffit on the market today.
What are the inches of air flow per square foot for Alside charter Oak fully vented 3 1/3 soffits. Their catalogue lists them as 3.2 inches per lineal foot. Since it appears there are 2 1/2 hidden vented channels I imagine that air flow would be approx 8 -9 inches per sq foot. Their catalogue lists the beaded Alside Alliance T4 at 7 inches of air flow per square foot. I am trying to achieve maximum soffit intake ventilation to work with newly installed GAF Cobra ridge vent. My old soffits have inadaquate soffit ventilation and I want to cool down unbearably hot attic caused by summer sun in NY. Eventually we plan to add extra insulation and finish attic into work studio for my wife. Eventually plan to add mini split AC,heater in attic for comfortable temperature to work in.
Very nicely explained and I really liked it.
