Roof Timber

In regions with long, snowy winters like Yozgat, a roof carries a heavy load for several months of the year. Rafters pass this load to purlins, purlins to posts and posts to the walls. A weak section in one link of the chain can make the roof sag.

We saw roof timber from pine in the sections your carpenter has worked out: rafters, purlins, posts, ties and sheathing boards. Using impregnated pieces where water gathers, such as eaves, valleys and around chimneys, extends the roof's life. Writing the list with part names and quantities speeds up the quote.

Roof rafter timber and snow load

Roof rafter timber is the first part that decides how a roof behaves under snow. If the rafter section is small or the spacing wide, the roof starts to sag in the middle under heavy snow and the covering is damaged. That is why the rafter size should be chosen by thinking about the roof's span and the region's snow load together.

Using straight, dry timber matters so the rafters stay in one plane; damp timber bends as it dries and the roof surface shows waves. Choosing treated rafter ends where they overhang the eaves protects the part that takes the most rain and snow and lengthens the roof's maintenance interval.
