Roof structure repairs in Prestatyn
A dipping ridge or a wavy roof slope in Prestatyn is usually a timber problem, not a tile problem. We look at the rafters, purlins, struts and ties from the loft, and at the wall heads from outside, before suggesting how to strengthen it.

What is the ground like in Clwyd?
With roughly 19,000 people, Prestatyn spans postcode districts LL19 in Clwyd. Neighbouring towns we cover: Rhyl (4 miles), Abergele (8 miles) and Flint (13 miles).
Clwyd has a mix of ground, with clay in some places and firmer rock in others. Parts of Clwyd lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Clwyd: Brick colliery terraces, seaside villas in Rhyl and Colwyn Bay, and post-war estates.
Which repair method suits a home in Prestatyn?
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
Purlin and strut strengthening
Undersized purlins are strengthened with extra timber or replaced, and new struts are taken down to a load-bearing wall. Where there is no suitable wall, an engineer designs the load path. Temporary props hold the roof while members are changed.
Best for: Sagging slopes, slim purlins and struts removed from the loft
What happens when we carry out roof structure repairs in Prestatyn?
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.
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.
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.

Roof structure repairs in Prestatyn: questions and answers
How much will roof structure repairs cost in Prestatyn?

Do you cover Prestatyn?
Yes. We take enquiries from across Prestatyn, including LL19, and from nearby places such as Rhyl and Abergele. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Clwyd prone to subsidence?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. Only an investigation can say why a particular building has moved.
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.
Do roof structure repairs need building control?
Usually yes, where the structure is strengthened or altered, or the covering becomes significantly heavier. In England and Wales that falls under Part A, in Scotland it generally needs a building warrant, and in Northern Ireland council building control approves it. We deal with building control where the work needs it.
