Warnings

Shingle packages should be protected from low & high temperatures and moisture before use. 

The roofing materials (OSB, water plywood) to be Shingle covered should be dry.

OSB panel end joints must be staggered  and a minumum of 3 mm of expansion gap must be left in all edges, in order to prevent shingle layer from substrate movement. BTM A.S. can not be held responsible for any damages on shingled roofs caused by inappropriately constructed decks.

An appropriate ventilation system should be provided in order not let roof temperature increase. 

Ventilation

An appropriate ventilation system should be provided in order to prevent premature failure of the roofing including blistering, buckling of the roofing shingles due to deck movement. If implemented correctly, proper ventilation methods can help ensure the maximum service life of roof assembly materials. It is recommended a minimum of at least 1 square metre of attic ventilation (both intake and exhaust) for every 300 square metres of attic space. This amount should be divided equally between intake and exhaust ventilation to insure proper air flow through the attic. Two types of exhaust vents are available; one with cap, other without cap. One exhaust vent for every 10 square metre of attic space to be installed near the ridge, for a proper ventilation. Also, proper intake space along eaves should be provided with bird and insect netting. BTM A.S. can not be held responsible for any damages on shingled roofs caused by inappropriate or no attic ventilation.
