Underlayment: a crucial part of every roof system
Do you agree that the roof is one of the most important parts of your house, especially as it protects you and your family from bad weather conditions? Let's have a look together to the underlayment shingle that IKO offers.
Take a look at the structure of a correctly installed shingle roof offering protection against all types of weather.
Shingles are not the only part offering protection, everything beneath them does as well. This invisible part is called the roof system. A key component of this roof system is the underlayment. The underlayment of a roof is a water resistant and waterproof membrane which is installed between the shingles and the wooden deck. As it is an extra layer of protection from severe weather conditions, the installation of an underlayment is mandatory. A shingle roof system without an underlayment is not covered by IKO warranty.

Types of underlayment
There are two basic types of underlayment used beneath roofing materials:
- Bituminous underlayment
- Non-bitumen synthetic underlayment
On the European market most synthetic underlays and breathable membranes are used as diffusion foils beneath wooden decks or wooden battens. They protect the insulation in case water would infiltrate through concrete or ceramic tiles. Diffusion foils cannot be penetrated with nails because the penetration between the membrane and the nail is not 100% watertight.
