Hi: I have a question for the pros. I'm In montreal. My neighbor was taking out the principals walls ( murs porteurs) of his triplex ( that is the mirror of mine and have no mitoyen wall) of the 1st and 2 floor and is replace it by a big column. both building have 3 floors)

at the beggining of march I have seen some cracks on the 3rd floor of my building.

I call the neighbor to ask if that is not due to his renovation and him told me that is due to a snow on the roof.

Could someone tell me the difference of cracks when it's due to a structure mess of beside building or when the weigth of snow?

Thank you very much, here the pics.



Je voulais vous demander une question. je suis a montreal et mon voisin depuis l'an passè qui a enlevè les murs porteurs du rdc et du deuxieme pour agrandir et il a mis une poutre aux deux etages( le batiment a 3 etages et le mien il est le mirroir du sien.

Au debut de Mars je suis allez au troisieme et j'ai remarquè quelques petites fissures sur les murs en haut des portes. J'ai demandè au voisin de venir voir (en pensant que c'est ces murs porteurs qui avais cause le problemme et quand il est venu il a dis que le problemme c'etais la neige sur le toit.

Ce que je voudrais savoir c'est comment differencer des fissures a cause du poid de la neige et celles dues a un mauvais calcul de structures.

merci beaucoup j'ajoute des photos.

Hi Gus.

Your question is best addressed by a structural engineer. However, houses are built with consideration given to withstanding snow loads that are typical for their region.
