Roof structure repairs in County Tyrone
Homes in County Tyrone are mostly market-town terraces. That matters for roof structure repairs: footings, wall construction and mortar all vary with the age of the building. Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first.

Why does the ground in County Tyrone matter for roof structure repairs?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon.
Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across County Tyrone, most homes are market-town terraces, rural houses and post-war estates.

Which repair method suits a home in County Tyrone?
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
Repairing or doubling rafters
Cracked, sagging or rotten rafters are strengthened by fixing a new timber alongside, often called doubling, and rotten rafter feet are cut back and spliced. The work is usually done from inside the loft with the tiles left in place, unless the covering is coming off anyway.
Best for: Individual rafters that have cracked, sagged or rotted at the feet
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
What happens when we carry out roof structure repairs in County Tyrone?
Send photos
Photograph the roof from across the street, both slopes if you can, and the loft timbers with a torch. Include the eaves and any cracks just below them. From these we can usually tell sag from spread and whether an engineer is needed.
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.
Written quote
You receive a no-obligation written quote listing each timber repair, any ties or straps, propping, scaffolding and making good. Once the repair is specified, the figure becomes a fixed price in writing.
Signs you may need roof structure repairs
- Struts, collars or ties cut out or missing in the loft
- Roof slope looking hollow or wavy between the ridge and the gutter
- Horizontal cracks in the wall just below the eaves or ceiling line
- Daylight through the tiles, or timber that is damp, stained or crumbling
Do you need approval 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.

Roof structure repairs in County Tyrone: questions and answers
Does the ground around Omagh cause cracking?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will roof structure repairs cost in County Tyrone?
On Northern Ireland rates, roof structure repairs starts from about £265 per rafter, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Can the roof be strengthened without removing the tiles?
In most cases, yes. Doubling rafters, adding struts and fitting ties can all be done from inside the loft with the coverings in place. Tiles usually only come off where timber near the eaves is badly decayed, or the roof is being re-covered anyway.
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.
Is a sagging roof ridge dangerous?
A slight, even dip in an old roof is often historic movement that stopped long ago. A sag that is getting worse, cracking timbers, walls pushing out at the eaves or recently removed struts should be checked soon. Avoid storing heavy items in the loft until then.
