Gable End Restraint/Straps

Question

Hi, buying a 1970s house and survey reports: "End restraint is inadequate to the roof structure and gable wall straps should now be fitted, to
connect the roof structure to the end walls. These are galvanised steel connectors which should be
spaced along the roof and ceiling timbers at maximum of 2-metre intervals. They should be
sufficiently long to be fixed to three of the roof timbers and have suitable noggins between the
roof timbers."

How much would this work cost approximately? Can the straps be attached to the brick, rather than making a hole to get strap through?

This is a really common survey comment on 60s/70s houses, so don’t panic — it’s usually a straightforward retrofit job, not a major structural nightmare.

💷 Rough cost (UK, realistic)

From current industry guidance:

* £80–£150 per strap (installed)  
* Typical gable wall needs ~15–25 straps
* So total:
    * £1,500 – £3,500 all-in (including access/scaffolding)

👉 In simpler jobs (good loft access, no scaffold, just internal work), you might see:

* £500 – £1,200 from a local roofer/carpenter

👉 If scaffold + making good externally is needed:

* £2k–£3.5k is very normal

Materials themselves are cheap (a few quid each for straps)   — you’re mainly paying for labour and access.

🔧 Can straps be fixed to brick instead of built in?

Yes — and in your case (retrofit), that’s exactly how it’s usually done.

There are two main methods:

1. Traditional (built into brickwork)

* Strap goes into mortar joint / cavity
* Requires opening up brickwork
    👉 Rare for retrofit unless doing major works

2. Modern retrofit method (most common ✅)

* Strap fixed directly to the inner leaf of brick/block
* Using:
    * anchor bolts / resin fixings
    * or screwed to timber plate fixed to wall

This is completely acceptable and widely used:

* Modern systems are designed to be drilled and anchored into masonry  
* No need to knock holes through the wall in most cases

⸻

🧱 What your survey is really asking for

They’re basically saying:

* Tie roof timbers → gable wall
* Spacing: every ~2m (standard)
* Strap length: long enough to hit 3 joists/rafters + noggins

👉 That’s standard Building Regs detail — nothing unusual.

It’s hard to give u a price without coming to have a look as I don’t want to over estimate you or under estimate my self cheers George

Hi, 
Depending on accessibility and all also not being able to view this type of works the room inside your loft area to install the horizontal noggins and straps rough estimate £450+

This is a very common recommendation on survey reports for properties built in the 1960s and 1970s, so I wouldn't be overly concerned. Gable restraint straps are an important structural component designed to tie the roof structure securely to the external masonry walls, helping to reduce movement caused by strong winds or natural movement over time. They are now standard practice on modern properties and are often recommended when buying older homes that were built before current building standards came into effect.
The cost will depend on the size of the property, the number of restraint straps required, access to the loft space, and whether any additional timber work, such as installing noggins, is needed. As a general guide, you should expect to pay between £600 and £1,500 for a straightforward installation. If scaffolding or additional structural repairs are required, the overall cost may be higher.
In answer to your question, the straps are not normally just fixed directly to the brickwork. They need to be securely anchored into the masonry using suitable fixings and extend across a minimum of three roof timbers, with timber noggins installed where necessary. This is what provides the structural restraint. Simply fixing a strap to the brick wall alone would not usually achieve the intended level of support or represent good installation practice.
Before any work is carried out, I would recommend asking the contractor to inspect the loft space thoroughly. Survey reports are often precautionary and based on a visual inspection, so an experienced roofing contractor or structural carpenter can confirm exactly what is required before providing a fixed quotation. They should also check for any signs of roof spread, loose timbers, or other structural defects while access is available.
My advice is to use a reputable, fully insured contractor who has experience with structural roof work. While restraint straps may not be the most obvious improvement, they play an important role in strengthening the roof structure and can provide long-term protection and peace of mind, especially when purchasing a property.
