If you read part 1 of our series on cedar roof maintenance, you learned why cedar roofs need to be properly maintained. Today, Patrick D. Morin explains what Roof Life of Oregon’s process is for cedar roof maintenance.
What we do to fix these is we have a tool that goes underneath the shake and pops the staples and then we pull the shake out and then we take a new shake and we put it in, we put the nail at an angle here and put it about a ¼” to the head and then tap the shake up into place so that the nail that holds this new shake in is up underneath the old shake. When we determine how the repairs are we’re looking for failed flat grain, this would be an example of a shake that was cut out of inferior wood compared to these vertical grain shakes surrounding it. You can see after 12 years the flat grain has fallen apart and this is 20% of the wood in a blue label #1 shake is flat grain, 80% is vertical grain. Flat grain means it is cut out of the round, if you look at the butt ends you’ll see that it’s got a curve to it, which makes all the grain on the top as big as your finger. Vertical grain means cut out of the straight grain and all the grain runs vertically and you can see how tight they stay even on a south wall or south facing roof that stresses the wood, it does the same thing on tile and composition, the roofs wear out where all the water hits.
Do you know if your roof is starting to visibly curve? If its been a while since you were last on your roof, if ever, then you need a Roof Life of Oregon roof inspection. To read the finale of our three part series on cedar roof maintenance process stop by our blog tomorrow.
