Couverture toit non rectangulaire

Bonjour à tous,

Après plusieurs recherches je me suis aperçu que beaucoup de questions trouvaient réponse ici. Je suis donc nouveau et ai en train de réaliser la couverture de mon garage et au fil de la réalisation plusieurs questions émergent.

1/ mon garage n a qu un seul angle droit cf ci dessous. Comment m y prendre pour la pose des liteaux et des tuiles (terreal romane evolution)? Si je vois qu il faut que je commence par l'angle droit je ne vois pas trop comment rattraper le décalage?

2/ les pannes sont installées. Je vais clouer (clou acier 200X7) les chevrons mais le temps est pluvieux et j aimerai avancer malgré tout. Cela pose t il un pb (clou rouillé etc..) de travailler sous la pluie?

Dernière question peut être idiote la section de mes liteaux est 25/32, faut il les poser avec pour hauteur 32 ou 25 et y a t il une importance?


Merci par avance a tous, je suis novice et un petit pb pour un professionnel se révèle être un gros souci pour moi.
