Replacing valley rafter without a roof tear off


I have a valley rafter that was burned in half, however the general fire damage to the roof is minimal... is there a way I can cut the nails of the rafters that tie into the valley rafter and just slide a new one in? How would I brace the roof during this?

How much of the rafter is left?? Could you sister new ones on either side??

Sawing thru the nails with a sawzall is not too hard. But if any of the plywod has joints on that rafter, renailing them would be difficult. Angle brackets might serve that purpose.

How long is the Valley rafter?
What type of building?
Do you need a permit?

Maybe you could run a "valley rafter" on each side under the other rafters, almost like a beam underneath. On both sides.

This is not a Diyer project without a professional like a framer or contractor with framing experience doing jobs like this.

The valley has to be replaced. Half of its burnt. No other way to fix it.

I don't see how a valley rafter could be burned that bad and not damage the decking and shingles, you may need to check that rafter again to see just how bad it really is.

If it is actually damaged that bad, check to see if there is a wall under the bad place that maybe could be used to support the rafter.

if this was caused by fire damage the question is, "do you have insurance?" if so, you should be able to hire a builder to make your home "whole" again.

Depending on what type of building, what type of construction, where it is located. There are ways to fix it.

Let's say perhaps it is a shed, no insurance, and the fire did not damage the surrounding area.
Then 'beams' under the rafters on each side of the valley would work. Yes they would be below the top of wall height at the bottoms.

That's why i asked the questions.

I would assume you would cut a portion of the roof sheathing to have access from the top. Shore up the rafters on either side of the valley beam. Remove the burnt beam and provide a new beam. Are the rafters hung off of the valley beam or toe nailed?
