The survey comes first, always
We do not quote a roof from a photograph and a postcode. We put a drone over the roof, walk the loft space where one exists, and record moisture, deflection, ventilation and daylight through the covering. That record becomes the scope, and the scope becomes the price. It is slower than a phone quote and it is the reason our variations are rare.
- High-resolution orthomosaic of every roof plane and all abutments
- Rafter dimensions, spacing, span and visible decay recorded
- Existing ventilation path assessed — the single most common cause of premature failure
- Moisture readings at eaves, valleys and around every penetration
Three packages, not an open-ended estimate
Every replacement is quoted as one of three packages — Basic Reroof, Energy Roof or Solar-Ready Roof. Each has a written specification you can compare against another contractor line by line. Where a roof genuinely needs something outside the package, it appears as a separately priced item rather than disappearing into a round number.
- Basic Reroof: covering, membrane, battens, flashings, rainwater goods
- Energy Roof: the above plus above-rafter insulation to a calculated U-value
- Solar-Ready Roof: the above plus the structural and waterproofing interface for PV
The structure is checked before the covering is chosen
Swapping a bitumen covering for concrete tile can more than double the dead load on a rafter designed decades ago. Where the covering class changes, we run the load case for the actual member sizes and the local snow and wind actions before the material is ordered. In Italy that check follows NTC 2018; in Austria it follows the OIB directive as adopted by the individual Bundesland; in Slovenia it follows the technical guideline referenced under GZ-1.
Hidden layers are photographed, not described
Once the covering goes on, nobody can see whether the membrane was lapped correctly, whether the counter-batten was continuous, or whether the valley was formed properly. We photograph each of those before they are covered, geotagged and timestamped, and hand them over with the dossier. If you sell the house, the next owner gets evidence rather than assurances.
