What good slate renewal relies on
Structure assessed first
We check slates, fixings and the support below before planning renewal.
Slate choice considered
Appearance, pitch, size and weight all affect the roof that goes back on.
Detail areas handled carefully
Valleys, abutments and roof penetrations need close attention on slate work.
When a slate roof needs full renewal
A slate roof can keep going for a long time, but when the slates, fixings and layers beneath start failing together, a full replacement may be the safer route. We assess the existing slates, the battens, the underlay and the supporting timbers before deciding how far the problem runs. Choosing the replacement slate also needs thought. Appearance matters, but so do roof pitch, dimensions, weight and the fixing requirements of the new covering. With MTS Northants, the decision is based on how the roof needs to perform, not just on making it look tidy again from the street. In Rushden, that careful start helps avoid the sort of slate work that looks right for a month and then starts telling on itself at the details.


Correct gauge, headlap and finishing work
Slate replacement depends on precise setting out as much as good materials. Gauge, headlap and fixing patterns all affect how well the roof resists weather over time. Detailed areas such as valleys, abutments, ridges, verges and penetrations need equal care, because that is where hurried workmanship soon shows up. We also plan the strip-off and replacement in weather-managed sections so the roof structure is prepared properly before new slates go on. A quotation from MTS Northants sets out the slate option, the condition of the roof beneath and the detail work needed to complete the roof properly.
