Installing Cedar Siding Is Easier Than you Think

What happens here

When installing siding in complex architectural areas, such as where a bump-out wall meets the angled A-frame roof, traditional vertical furring strips may not be practical. In these instances, use small spacer blocks to maintain consistent spacing between the siding and the roof line. Custom-cut flashing pieces are essential here; these should be carefully shaped and installed to precisely fit the angles, ensuring that any water is directed away from the siding and preventing it from flowing behind the furring strips. The custom flashing pieces should also be of a thickness that matches the siding boards for a seamless appearance.

Goal: Properly manage water drainage and maintain an aesthetic finish in complex architectural joints.

Tools and materials

  • 15-Gauge DA Nailer Ryobi — Fastening siding and flashing pieces
  • Cedar Tongue and Groove Siding — Exterior cladding in complex areas
  • Custom Flashing — Directing water away from critical areas at roof-siding intersections
  • Exterior-Grade DA Nails — Securing siding and flashing
  • Spacer Blocks — Maintaining consistent spacing between siding and roof lines
  • Waterproof Sealant — Sealing any exposed gaps in complex corners to prevent moisture and pest entry

What they say

business. the side of the bumpouts. They're getting a little bit tricky just because we're meeting with the A-frame of the roof. Uh we have our the same uh vent uh siding vents down below. We have our first strips going up that way. Here's the problem. There's no way of getting first strips going up the side here. And the reason why is we would have to stack so many of them for each, you know, 5-in board to actually get something to get nailed into on the side that it's almost impossible. So, we're just going to pivot it on the side. Yes, there's not going to be any air flow there, but it's a small piece. But the second thing that's most important is we also have to deal with drainage in terms of from the roof. So we got a little spacer block here just to continue this fur block to be equally spaced from the roof just cuz you know symmetry. And then second of all, we're making our own little custom flashing here where it actually holds the same exact thickness of this board. We're going to nail it across and because it's on a downward slope, anything that ever goes underneath here will catch that and kick it out and not go behind our spaced out fur strips and our beautiful cedar sighting. So, here's a little bit of a finished product on the other side. Water comes in. Flashing comes all the way up to here. You could see it right there sticking out. Comes down here. This is all siliconed down behind. Comes in there and then kicks all the water out this way. Not going behind the siding or anything. I think that'll do. I think overall installing cedar siding is not that difficult or different than traditional sighting. Again, apart from ventilating and fur strips and all that stuff, but the only part that gets a little bit more complicated is because of the gap that we're creating for airflow. It makes adding flashing a little bit more difficult because now you have all these nooks and crannies that are exposed. So then you have to seal it with extra material like a waterproof silicone or something like that to make sure that nothing trickles in there. Everything is diverted, but also no bugs are going to get in
