When a roof in Greenbank has had several rounds of patch repairs over the years, one of the most important parts of carrying out a proper re-roof is removing all of that old work rather than simply building around it. It can be tempting to think that a new roof covering could go over the top of existing patches to save time, but this approach usually just carries old problems forward into a brand new roof, undermining the whole point of replacing it in the first place. Whatever was causing a patch to be needed originally is very unlikely to have resolved itself simply because a new covering has been laid on top.
Stripping back a roof to its structure means every old patch, whether it's a cracked tile bedded in mortar, a strip of felt tacked over a gap, or a piece of flashing that's been resealed multiple times over the years, gets taken off and properly assessed on its own merits. This is often the stage where the true condition of a Greenbank roof becomes clear for the first time in years, including any timber that's been quietly affected by long-term damp behind a patch that looked entirely fine from above. It's not unusual for a roofer to find two or three separate generations of repair layered over the same small section once everything is finally stripped back to bare timber.
Removing previous repairs also allows the new roof to be built correctly from the deck upwards, with a continuous membrane, properly spaced battens and consistent detailing carried through at valleys and abutments. Patch repairs, by their very nature, are localised fixes that rarely tie in cleanly with the rest of the roof structure, so leaving them in place beneath a new covering can create weak points that undermine an otherwise well-installed and carefully specified new roof. A roof is only as reliable as its least consistent section, and an old patch left in place can end up being exactly that section for years to come.
For homeowners, seeing old patches removed can sometimes reveal more underlying issues than expected, but this is generally a good thing rather than a setback to the project. It means problems that have been quietly developing for years, hidden under a series of temporary fixes applied by previous owners or contractors, finally get addressed properly instead of being covered over yet again for a future owner to eventually have to deal with themselves. Being told about a problem while it's still visible, rather than discovering it later through a leak, generally makes it far easier and cheaper to put right.
