How do you fix rafters that are rotten at the end?

considering your rafters support the weight of your roof they need to be repaired or replaced properly without looking its really impossible to say exactly what will be required but would budget for scaffolding at the very least.as you will have to remove at least part of the roof to access them, the other issue is if the ends of the trusses are rotted then there is a good chance the wall plate may also be damaged & need replaced

To carry out the work safely I would use a scaffold, if there is sufficient overhang on rafters they can be cut back but this is a job which would require a full inspection first, there is always a solution, it depends on many factors. Des Brandes Roofing

If the rot has not gone to far it is possible to cut out the defect timber and replace with new However this woukd still require scaffold to carry out the work Also a percentage off your roof at the bottom would need removing to carry out this work as there may be work needed to any wall plate that bay be infected with rot Either way scaffold will be required

This is pretty major work scaffolding and stripping the bottom of the roof is right, it should be able to be repaired without stripping the hole roof but all depends how bad it is, without seeing it is hard to comment, theses major repairs are expensive but their are lessons to be learned here, as these major expensive repairs can be avoided by simply dealing with any roof related problems as soon as you notice them, this sort of damage and rot doesn’t happen over a few years we’re talking a good decade or two or abuse and neglect.
