Also It is not recommended to lay on top of the material any heavy objects to avoid deformation of the sheets. As for carrying metal roofing, it is necessary to do it in an upright position, without having to allow material kinks. Keep the shingles on wooden beams at a distance of not less than 20 centimeters from the ground.
Laying of metal tiles begins with the installation of rafters.
