Hi i have just discovered one of my roof rafters in the loft has a big ish crack in in it, would this concern anyone and would it be a easy enough fix? aslo what would cause this to happen?. Ive had a re wire done and they have cleated the new cable to both sides of the rafter but i wouldn't have thought that would have caused this.
It's deffo not new. Look at colour of timber in the crack/shake. Was probably like it when originally installed and just delegated a bit over time
If you're really worried about it, get some perforated galv band and wrap it around and screw it in. Clamp the rafter first.
