A dipping ridge or a wavy roof slope in Blairgowrie 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.

Which repair method suits a home in Blairgowrie?
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
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
What happens when we carry out roof structure repairs in Blairgowrie?
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.
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.
Rules for roof structure repairs in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Roof structure repairs in Blairgowrie: questions and answers
How much will roof structure repairs cost in Blairgowrie?
Guide prices for roof structure repairs in Blairgowrie start from about £285 per rafter, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Blairgowrie?
We do. Blairgowrie and the surrounding area are covered, including nearby Perth and Dundee. A free initial assessment from your photos is the first step.
Is the ground in Perth and Kinross prone to subsidence?
Perth and Kinross is largely Old Red Sandstone and Highland rock with glacial deposits and river alluvium along the Tay, which can be soft and flood-prone. Only an investigation can say why a particular building has moved.
Do I need a structural engineer for roof repairs?
For like-for-like repairs to a few rafters, often not. Where purlins, struts or ties are being redesigned, the covering is getting heavier or the walls are being pushed out, you usually do. Where the repair needs an engineer’s design or sign-off, an independent chartered structural engineer is appointed, and we can arrange this.
What is roof spread?
Roof spread is when the feet of the rafters move outward because nothing is tying them together firmly enough. As they spread, the ridge drops and the tops of the walls are pushed out, often with a horizontal crack below the eaves. It is fixed by adding ties, collars or straps, sometimes with rebuilding.
