Metal Roofs: An Insulation Guide

Corrugated metal is not an uncommon roofing material. In fact, it has been popular for quite a long time. A lot of buildings, offices, communal spaces and homes have metal roofs in order to reduce noise pollution and save energy. However, just like with any other type of room, insulation is the issue that needs to be tackled in order to achieve energy efficiency. With properly insulated metal roofs, you will retain the heat in the building while blocking the outdoor noises. If this checks all the boxes for you, read on for a comprehensive insulation guide for metal roofs.

Foam batting is the best option

If you are still thinking about what the best option when it comes to insulation material is, foam batting combines flawlessly with materials such as metal roof sheets. As you probably already know, fiberglass comes in roll-ups, whereas foam batting comes in panels (or, in other words, it is purchased in panels). It also offers you some wiggle room – it can be used on the inside or the outside of the sheathing. It is highly malleable, which is one of the most important traits of any material in the world of construction.

Staples will make sure it is fixed

When we talk about staples in construction, especially when it comes to roof insulation, we are not discussing your regular paper punchers. These staples can easily go through several inches of insulation and they are probably the easiest way to attach metal roof insulation and keep it fixed. Furthermore, they will not create large or particularly noticeable holes in the sheathing and you can always remove them if additional repairs need to be made (which cannot be said for most of other insulation fasteners).

Paper wrap can be very helpful

Lay down paper wrap on the sheathing. It will prevent water from accumulating in the small space between the metal roof and the sheathing. This is important for several reasons and the most important one is definitely the factor of mold. Since this space is damp and dark, mold can develop really quickly and cause all sorts of respiratory health issues to the residents. This is a specific problem that becomes really hard to detect or pinpoint once it has grown to dangerous proportions. People will usually search for the source of the problem in different places and this space between the metal roof and the sheathing will be the last thing on their mind. Therefore, make sure to put the paper wrap on the sheathing and prevent this problem from ever occurring.

Create the airflow

When you are constructing and insulating metal roof, there is an additional method you can apply to lower the chance of mold infestation – create small gaps to let the roof breathe. This can make metal roof maintenance much more manageable. These spaces between units of insulation should be no wider than 3 millimeters. If this is not done as precisely as possible, the problem of a leaking roof can emerge, which is followed by other issues.

Solving a small problem now can prevent a big problem later

You can argue there is hardly such a thing as an impregnable roof. This is definitely true when it comes to regular non-governmental and non-military buildings. For example, a constant flow of water will find its way through anything, and it can create big problems with your roof over time. Metal roofs are not immune to damage or corrosion. In order to stop these ever-evolving problems in their tracks, you need to be vigilant and give a professional a call as soon as you notice the need for any potential roof leak repair. Pay close attention to the state of your metal roof during and immediately after the rain season.

We all want to achieve the perfect balance between comfort and practicality. Homes and residential buildings usually go for different roof material, but metal sheets are just as good as your average roof tile. It is quite unfair to see people turning their back to metal roofs due to the very nature of metal – it cannot retain heat. However, with a bit of knowledge and solid insulation, it is a perfectly reliable kind of roof material.
