Another listed building question

[einstein]

I recently bought my farmhouse that i and my dad had rented for the last 60 years.
It was listed in 1984,this appears to have gone unnoticed by my landlord as my dad was never informed.
Fortunately very little work has been done on it since it was listed.
On reading the listing detail i noticed an error. The roof is said to be of collyweston stone slate. In fact it is only the back of the roof that is of colly. The front is of a modern square tile changed well before the house was listed, almost certainly in the late 60s. Although this may be difficult to pinpoint.
Really it was quite a poor effort from whoever did the initial inspection not to notice.
I feel obliged to point it out to historic england and do wonder whether it would be sufficient grounds for getting the house delisted.
Has anyone had any experience with this?

In one way it works against you that very little work has been done, if it had been heavily modernised by the previous owners it would have been better for you trying to get the listing removed. The good part is that they can't have ago at you for working on it.
As to the roof it is imperative that you contact them and get it noted that much of the roof is covered in modern tiles, otherwise you could get hammered in the future, just be seen by a busybody repairing the front roof who reports you and a coachload of clipboard holders would descend.
Did the landlord inform you of the listing prior to purchase ? On most buildings a listing knocks a fair amount off the valuation.

Can be very useful having errors on the original listing. I have quite a few on mine and exploited some of them to my advantage to get the house restored how I want it including en-suites etc By agreeing to reinstate the weavers windows which had been blocked up.
