Was up in the attic and saw this weird discoloration at the intersection of the decking and the joist, is this bad and should I do something about it?
pick a screw driver and try your hardest to punch a hole on it.If you can, then you have some bigger problems.
>>2845687It's water damage. You got a leak that dries out in the heat and as the process repeats over and over the wood blackens from the rot.
>>2845687What ar you doing up in the attic?What are you? Some kind of ghost hunter?
>>2845769The house is from the 60s, but the roof has been reshingled recently before we bought it. How can I tell if it's just an ancient leak that is now no problem?>>2846111installing new bathroom shit vent you goon
>>2845687Test with a screwdriver to see how bad the rot is already, just try and jam it though if it's rotten it'll go through. Test with a moisture meter after it rains to see if the wood there is still getting wet, or if it's an old leak. If it is rotten, you will need to sister a support beam to the main rafter, and likely replace the wood and roofing above it as well.
>>2847027What are you? Afraid of ghosts or something?
>>2847027>The house is from the 60s, but the roof has been reshingled recently before we bought it. How can I tell if it's just an ancient leak that is now no problem?Get some water soluble ink. Children’s Crayola markers are probably a good cheap choice. Make a visible pattern over the spot and general area, with clear distinct lines. Take a photo or several. Wait till it rains heavily, and then maybe wait a few days. Check the pattern you drew with the markers. If the markers have bled you may have a leak or other source of water. As for mold, naybe you have some, but there are sprays you can get at Home Depot etc., that will kill a small spot quickly. Major rot also takes a long time, so I wouldn’t worry too much about that.
