Can You Renegotiate a House Price Over Roof Defects?

When the roof becomes a negotiating point

A buyer's survey sometimes flags the roof. It might mention slipped tiles, a worn ridge, failed flashings, sagging lines or an old covering near the end of its life. Mortgage valuers may also note it. Once the survey is in your hands, you know about a cost that was not in the asking price. That is the usual moment to open a conversation.

Timing matters. The price can be discussed any time before exchange of contracts, but the earlier you raise it, the better. Our page on what to do when a homebuyer survey flags the roof covers the steps from there.

Not every comment in a survey is a defect worth negotiating. Surveyors use cautious wording and often recommend further checks as a matter of course. The aim is to work out what is real and what it would cost.

Roofs are a common reason because they are expensive and easy to underestimate. A buyer cannot see most of the detail, and an agent's particulars rarely mention the roof. A fresh set of eyes at the right moment can turn a worry into a number you can work with.

Evidence that carries weight

A roofer's inspection gives you a specific finding. It describes what is wrong, where, how serious it is and what the repair would involve, with photographs. A fixed written quote puts a number on it. That lets you ask for a precise reduction, or for the seller to carry out the work, rather than a vague discount.

Be realistic about the figure. The cost of putting right a defect is a reasonable ask. The cost of an upgrade you would like is not. If the roof has years left and needs only a modest repair, a request for a new roof will not be taken seriously. If it has run out its useful years, the figures in the guide to the working life of a new roof help place it.

You can ask the seller to give access for the inspection. Many are willing, because they want the sale to go through.

It helps to keep the tone calm. A seller who feels accused tends to dig in. Present the finding as information you have just received, show the photographs and quote, and ask how they would like to deal with it. Most sales that stall over a roof recover when both sides can see the same evidence.

What the seller might offer

There are a few typical outcomes. The seller may agree to a price reduction that reflects the repair cost, to carry out the work before completion, or to hold back an amount from the sale. They may refuse, particularly if they think the survey exaggerates the problem, or if they have other offers. A buyer then decides whether to proceed at the asking price, walk away or find a middle path.

Any agreement should be in writing and go through the solicitors. If the seller will do the repair, ask for the contractor's details, a guarantee for the work and photographs afterwards. Whoever does the work should give you their guarantee on paper before the job starts.

Be wary of an offer to do the repair cheaply and quickly after exchange, with no paperwork. It rarely ends well.

If the seller refuses to move, you can also ask whether the roof was ever repaired and whether any guarantee survives. A transferable guarantee on a recent repair is worth having, and the page about passing a roof guarantee to a new owner explains how that works.

Where a solicitor and a surveyor come in

We are roofers, not lawyers, so we do not advise on the legal side. Your solicitor handles the contract, any retention and what happens if the work is not finished. A surveyor may be able to confirm a finding or give a wider opinion on the property as a whole. For the difference, see our answer on whether a roofer or a surveyor should inspect your roof.

What we can do is the roof side of the question: a free survey with photographs, a plain written finding and a fixed quote that you can take to the seller. See our page on roof inspections in Basingstoke for how that works.

A retention is another route that solicitors use. An agreed sum is held back at completion until the repair is done and signed off. That keeps the money tied to the work.
