Can I angle pergola rafters?

MBaybut | Posted in General Discussion on December 23, 2008 01:25am

Hi,
I was thinking of how I could increase the shade value from a pergola and I wanted to know if I tilted the rafters, (looking end on) would that cause them to eventually sag due to them not being upright.

    Like louvers? Sure add a stiffener.

      Thanks,
      Yes, like louvers. I was only thinking about 10 deg off vertical. What's a stiffener?

          I'd recommend something else, otherwise you'll have those two damn bathtubs to deal with.A Great Place for Information, Comraderie, and a Sucker Punch.

          Causes too much expansion, won't be able to keep the erection up for long. If it lasts 2 days, you know who to go see.

        Just thinking something like a spine under or over at a 90 degree angle, like a strong back or the actuater on actual operable louvers. A cross wise member to help keep them from rolling or sagging.

        But maybe not needed deprnding on your method of joiney at the ends or else where. I'd not have the members resting ona corner, I'd rip the bevel of tilt and have a flat surface on the bottom and top.Spheramid Enterprises Architectural Woodworks

    wider spacing or shorter members would have the same effect.

    If possible, re-arrange them so that they run north-south.  This orientation will provide at least partial shade during everything except direct mid-day sun.

    After I posted this, I got to wondering where you might be given that it's about 5 degrees outside here and I'd give anything to see more sun and not less.  Then I looked at your profile and see you're in St. Pete.  Ah, sunny St. Pete, I lived near Coffeepot Bayou from '82-'90.  Too bad about them Rays...

        With luck, it'll hit 15 here today, but its a dry cold.  Today, I get to replace a Velux that swallowed a limb during last weeks ice storm, on a metal roof, 10-pitch, yippee!.  At least if I fall off, there's a six-foot heap of snow to break my fall.  On the upside, if I forget my sunscreen, it's no biggie.

    if you tilted them then add blocking between each joist miterd to match the angle and offset the blocking.  might add visual interest too.

    on a pergola i built i added 1x3's across the top of the joists which added nice shade and interesting lines to the pergola and the ground......

      Thanks,
      I was intending to put up 1x3's also, so maybe that will give enough shade. The original idea was to have them slanting to the south so offering more shade in the summer and letting in more sun in the winter.

        1x3's crosswise add quite a bit of shade.  depending on your latitude standing the 1x3 on edge might help too with shade.

        maybe you could get really fancy and motorize them.  get a linear actuator motor on timers thats pivots them for ya a couple times a day and maximize sunshade and winter warmth....

        ok, maybe thats too far, but i bet it would make the pages FHB.. haDan Lynn, Dan Lynn Construction, Joliet, IL

          I agree - it will look *weird* to have the main beams angled - run additional lumber over top, spaced.
