One of the first things to consider is the type of insulation you want to use. Some people prefer to use spray foam for their roof insulation, especially in renovations, but this type of roofing material can be expensive to purchase and install. For those who want to do it themselves, a more affordable option is to purchase radiant foil. It is double-sided and much easier to handle than rigid foam. Though it is not a good thermal conductor, radiant foil is most likely effective for the purposes it was designed for. Additionally, you should look for an “R” value, which can help you select the appropriate type of roofing insulation.
The main disadvantage of excessive insulation is that it can reduce air flow. Fresh air is necessary for healthy living. Moreover, if moisture builds up in your walls, it can cause mould and mildew to grow. This is not only unsightly, but can also be harmful to your health. There are many reasons to invest in better insulation. The first one is to reduce your energy bills.
Second, you should consider installing insulation stops. These are barriers that prevent insulation from touching the underside of your roof. They can be made of cardboard and easily installed with nails or staple guns. They prevent frost from forming on the interior roof surface and prevent rot and shingle damage. It also prevents excess insulation from touching the underside of the roof. For better insulation, install insulation stops before soffit vents. This also helps air flow.
Third, you can also consider installing polyurethane spray foam to seal cracks in the roof. This type of foam is applied to the underside of the roof deck. It bonds to the slates, thus sealing out moisture and preventing wind and heat. Besides that, spray foam is easy to install, even in awkward corners and small spaces.

Aside from sealing gaps, you can also use a foam baffle under your roof to maintain air gaps. This way, your roof will remain dry and prevent the formation of mould and moisture. By installing the foam baffles near the edges of your roof, you can install insulation from the bottom and then finish the process with drywall. The finished product can be covered with drywall, so you can make your roof look nice and neat.
