Roof structure repairs in Newtownards
Many older roofs, in Newtownards and across County Down alike, were built with slim purlins and few ties. A little historic movement is normal, so we check whether the roof is still moving before recommending how far the strengthening needs to go.

What should you know about the ground under Newtownards?
Newtownards (BT23) has around 29,000 residents and sits in County Down. Nearby places we cover include Bangor (5 miles), Holywood (6 miles) and Downpatrick (18 miles).
Clay shrinkage is less of a concern in County Down, so other causes such as drains, poor footings or older walls are checked first. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across County Down: Victorian seaside houses in Bangor and Holywood, brick terraces and post-war estates.

Loft and outside survey
On site we check rafter sizes and spacing, purlins, struts, ties and wall plates, look for rot and past alterations, and measure any lean at the wall head. The covering is noted too, because its weight affects the repair.
Engineer’s design where needed
Where purlins, struts or ties must be redesigned, or the roof carries a heavier covering, an independent chartered structural engineer is appointed to specify the work. We can arrange this, and their design sets the sizes and fixings.
Prop, strengthen and tie
The roof is propped where members are being changed, then rafters, purlins, struts and ties are repaired or added as specified. Coverings disturbed by the work are relaid, and building control inspects where the work needs it.

Methods for roof structure repairs
Wall plate replacement
Rotten or crushed wall plates are replaced in short lengths while the rafters above are propped, and bedded on the wall in mortar. The plate is then strapped down to the masonry. It is often combined with rafter foot splices along the same run.
Best for: Rot along the eaves where rafters bear on the wall
Tying in roof spread
New ties, collars or steel straps connect opposite rafters, or fix the rafter feet and wall plate firmly to the ceiling joists, so the outward thrust is resisted. Leaning wall heads are strapped back to the roof, and a badly spread roof may need partly rebuilding first.
Best for: Walls pushed out at eaves level by spreading rafters
Rules for roof structure repairs in Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Frequently asked questions
How much will roof structure repairs cost in Newtownards?
Guide prices for roof structure repairs in Newtownards start from about £265 per rafter, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Newtownards?
Yes. We take enquiries from across Newtownards, including BT23, and from nearby places such as Bangor and Holywood. Send photos for a free initial view and we will tell you what happens next.
Is the ground in County Down prone to subsidence?
County Down is mostly drumlin till over older rock and granite in the Mournes, with soft estuarine ground around Belfast Lough and Strangford. Only an investigation can say why a particular building has moved.
Why are there cracks just below the eaves?
A horizontal crack just below the eaves, along the front or back wall, is a common sign of roof spread. The rafters push the top of the wall outward and the masonry cracks where it hinges. Corroded wall ties can cause similar cracks, so the cause needs checking.
Can heavy concrete tiles damage a roof?
Yes, if the frame was designed for lighter slate or tiles and was not strengthened. The extra weight makes rafters and purlins sag and can bring on roof spread. Before re-roofing in a heavier material, have the structure checked and notify building control.
