Use of underlay and bituminous membrane

The colors of IKO Armourvalley membranes are matching the colors of IKO shingles. This creates the same beautiful look as on the main roof. Armourvalley is a high quality APP modified roll especially for roof valleys but it can also be used for low slope roof areas that are not suitable for shingles. Armourvalley cannot be applied directly on a wooden deck. First an underlay (e.g. Armourfix) must be installed as a base sheet. Armourfix is an underlay for IKO Armourvalley. This underlay must be applied with a good mechanical fastening; this means roofing nails or screws every 20 cm in all directions. Afterwards the IKO Armourvalley must be fully torched on it.

Flat roof connected to shingles roof

A very important detail is where the flat roof is connecting the pitch roof. Armourfix and Armourvalley membranes must be installed and extended 60 - 90 cm up the main roof underneath the shingles in order to assure a waterproof connection.

The starter strip and first row of shingles must be applied 25 cm from the bottom of the slope roof (or main roof) above the slope transition. The starter strip must be securely glued on the Armourvalley membrane.

Drawing sloped roof draining onto flat roof

Tip! Some roofers install a metal flashing under the starter strip to protect the lower part of the roof to accumulate water and snow loads.

Important! Remember: the slope of a flat roof must allow the water to drain from the roof. If water is not drained from the roof, any weak detail can be a potentially leakage in future!

The summer is that time of year where we are faced with lots of storms, often accompanied with impressive lightning spectacles. Even though it is a majestic natural wonder, it can often cause troubles.  Protecting your home against an impressive lightning strike could save your life, the lives of your beloved ones, your home, its contents and all the electrical components.

Unfortunately you cannot prevent a flash of lightning striking on your home. But what you can do is nullify or reduce the ruinous effects of a lightning strike by having a professionally installed lightning protection system in your home.

Lightning striking roof

Lightning protection explained

The task a lightning protection system performs is very simple. It provides a path, created by specialists, on which a lightning strike can travel. If your home is armed with a lightning protection system, the damaging power of this lightning strike will be directed safely into the ground. This leaves your home, family members and personal belongings unharmed.

The lightning protection system consists of air terminals (rods), a conductor (cable), bonding with metallic bodies and ground electrodes (counterpoise cable or ground rods) designed to protect the building structure and its occupants.
