Low roof slopes

Otherwise IKO also has a smart solution for extremely low slopes from 4°- 15° without nailing: IKO Thermo System. As tiny houses are often covered with OSB on walls and roofs, Armourbase Thermo AD is ideal for a low sloped wooden roof. This special underlayment can be torched on top of the OSB and any IKO shingle can be layed to that melted bitumen without nails. This means that the roof is not penetrated by any nail and the very low slope is 100% secure against wind driven rain and water infiltration. For all slopes greater than 15°, the shingles are already properly nailed following our regular application instructions.

What is needed for a complete installation?

The small roofs on tiny houses are simple, installation can be handled very easily. All you need for the application is a hammer and a cutting knife with the hook blades. Don’t forget to use an IKO Armourbase underlayment, they must be installed first. Armourbase underlays are very durable and strong, thanks to their polyester reinforcement. Furthermore they are 100% watertight because the polyester inlay is saturated by high-quality modified bitumen.

Moisture is one of a builder’s biggest concerns. Water can damage wood, ruin structural integrity, and even cause toxic mold which can lead to severe health problems. Therefor the walls and the roof must be well insulated, and the wood must be treated against moisture and all-weather conditions. Roofs on tiny houses are usually insulated between the rafters and the best solution for this type of structure is the IKO Armourvent Multi. Armourvent Multi is ventilation in a roll, and you can ventilate a gable roof as well as a shed roof without any problems. Finally, is AV Multi covered with cap shingles, which is aesthetically pleasant.
