We are under contract to buy a house w/a 2 year old roof. The owner started to finish the attic (got about 50% done w/insulation and sheetrock) but isn't going to complete the work - we will pick it up ourselves later.

At our inspection the inspector pointed out that there should be a ridge vent and venting in the soffits (newly covered w/aluminum) in order to preserve the new roof, if the attic is to be finished. Luckily, he thought that little, if any, of the thus far finished work would need to be undone to put in the venting.

Has anyone installed a ridge vent (separate from a whole roof job) and if so, in what range did it cost? I've called a couple of local roofers to give an estimate as well - but any recommendations would be welcome.

Just trying to get a sense of the overall cost, to see if we should negotiate for all, or some, of the cost/work to be handled by the seller, or whether we should take it on - we don't want to nickel and dime the seller but don't want to get stuck with something fairly major that should have been done either.

Best to all,

Julie

Julie,

Installing the ridge vent is not a major undertaking. However this depends on the style of roof and/or pitch. Gable, Hip, 14 on 12, 8 etc.
Regardless, it wont increase the cost too much.
The soffits can be vented with small insert vents.
As for the cost.... It all depends on the above.
Good luck.... Mike

If insulation batts have been installed between the roof joists, without a plastic air venting channel, the ridge vent will not solve your problem. You will have more work to do.

Since this is an existing roof, I think you are going to find that cutting in the ridge vent will cost you more than you are thinking.

Price depends on the factors above, get a quote or four.

Good luck.

All good advise..... Keep in mind that My home has no ridge or soffit vents with (2) layers of asphalt (1) being the original and is 34 years old.
It's a matter of opinion and how much sun the home gets.
Good luck.

Hmm, the seller started installing the insulation batts and drywall but only got about halfway. Think there's any way I can still put a plastic venting channel in there? Would that reduce the need for a ridge vent?

The original shakes were taken out and replaced with plywood, so there is a bit of air space between the lathe (?) and plywood.

Thanks for your suggestions - this is all very helpful!

Best,

Julie

A little space will not do it.
You will still need a ridge vent.
Drywall is cheap. Plan on ripping it down, removing the batts, installing the air channels, then installing the insulation and the new drywall.

Get a permit.
