It's not unusual for homeowners to have a go at fixing a small roofing issue themselves, particularly something that looks fairly straightforward like a loose tile or a gap that's letting a draught through into the loft. Around Greenbank, where many properties have been owned by the same family for years or passed through several sets of hands over time, it's fairly common to come across a roof with a few of these DIY interventions somewhere in its history, some more successful than others. Many of these fixes were carried out with the best of intentions, often as a quick response to a leak spotted during heavy rain rather than as part of any considered plan.
The difficulty is that DIY repairs, however well-intentioned they were at the time, are rarely carried out with the same materials or techniques a professional roofer would use. A generic sealant applied around a flashing detail, for instance, might hold up for a while but can react badly with the surrounding materials over time or simply fail faster than proper lead flashing or a correctly detailed system would have done. Roofing nails or fixings that aren't matched to the specific tile or slate type being used can also cause problems that only become clear much later on, sometimes cracking the material they were meant to secure.
When it comes time to re-roof a property, these earlier DIY fixes can complicate the job in ways that aren't always obvious beforehand. Old sealant needs to be carefully cleaned off before new work can be properly bonded or fitted in its place. Incorrect fixings used in the past can have damaged the tiles or the surrounding timber over time. In some cases, a well-meaning repair has actually trapped moisture against timber rather than keeping it away as intended, creating a problem that simply wouldn't have existed otherwise. Even something as simple as painting over a damp patch rather than tracing its source can delay proper treatment for years, allowing the underlying issue to spread quietly in the meantime.
None of this is really a criticism of homeowners trying to look after their own property between professional visits; it's simply that roofing work benefits enormously from experience with how different materials behave together over time, something that's genuinely hard to know without doing it regularly as a trade. Flagging any past DIY work to your roofer before a re-roof begins helps them plan for it properly in advance, rather than being caught out partway through the job once it's underway.
