Do I Need a New Roof?
Warning signs that a roof may need replacement, when a targeted repair can work and how Bromley homeowners can obtain an honest inspection.
A leak does not automatically mean that the whole roof needs replacing. The right decision depends on the age and condition of the covering, whether damage is isolated, the state of the supporting structure and how often repairs have been required.
Signs that a repair may be enough
- One or two storm-damaged slates or tiles
- A local flashing or valley defect
- An isolated puncture on an otherwise sound flat roof
- A blocked or leaking gutter causing water to back up
- A roof covering that remains generally secure and serviceable
Signs that replacement should be considered
- Slates repeatedly slipping because fixings are failing across the roof
- Widespread cracking, blistering or open laps on an ageing flat roof
- A wet, rotten or badly deflected roof deck
- Rot or structural movement in rafters or other timbers
- Repeated repairs in different areas with only short-lived results
- A proposed repair cost that is poor value compared with a properly specified renewal
What an inspection should establish
The inspection should identify the likely route of water, the extent of deterioration, whether the surrounding covering can support a repair and any access or safety requirements. Ask for photographs and a written scope rather than relying on a price alone.
Compare complete scopes
A new-roof quotation should clearly describe coverings, underlay, battens, insulation, ventilation, flashings, timber allowances, scaffolding and waste removal. Two prices are not comparable if one omits essential work.
