A DIY roof leak repair kit is most useful when you already know what defect you are repairing. Local flat-roof repairs depend on diagnosis, substrate preparation and choosing a system appropriate to the defect.
Before buying a repair kit
- Identify the likely external entry point.
- Check whether the damage is genuinely localised.
- Confirm the surrounding roof and deck are sound.
- Check substrate compatibility.
- Make sure the area can be accessed safely and prepared in suitable conditions.
What a reinforced kit does differently
A reinforced system uses waterproofing liquid together with separate fleece reinforcement across the prepared repair area. It is intended to create a reinforced local repair rather than simply brushing a coating over the symptom.
What SealForge includes
- 1 litre polyurethane liquid rubber
- 1 square metre fleece reinforcement
- Primer
- Catalyst

- Rubber gloves

Not sure whether DIY repair is appropriate?
Use the repair suitability guide and Flat Roof Leak Help Centre. Widespread damage, a soft or sagging deck, structural movement, an uncertain source or unsafe access requires professional assessment.
