What leak diagnosis helps us put right
Moisture route followed
We trace where water has travelled instead of guessing from the ceiling mark.
Likely sources checked
Tiles, slates, flashings, valleys, joints and blocked drainage all come into play.
Damage around the leak considered
We look at what continued water exposure has already weakened nearby.
A leak stain does not always mark the entry point
A damp patch on the ceiling is useful evidence, but it is not always the exact place where the roof is letting water in. Moisture can travel along underlay, timbers and other parts of the roof before it finally shows indoors. We trace that likely route and check the common sources, including damaged tiles or slates, failed flashing, valleys, roof penetrations, flat-roof joints and blocked drainage. We also look for the less dramatic warning signs such as musty smells, discolouration and leaks that only appear in wind-driven rain. With MTS Northants, leak repair starts with finding the path the water took, not guessing from the puddle. In Rushden, that careful look often saves a lot of repeat visits.


Repair the source and what the leak affected
A proper leaking roof repair needs to deal with the entry point and any nearby materials weakened by continued damp. That may mean renewing the damaged component, restoring the weatherproof junction around it and checking the surrounding area for hidden deterioration. If the inspection shows that the leak is part of a broader failure, we say so rather than dressing up a short-lived patch as a real fix. A quotation from MTS Northants sets out what is causing the water entry, what has been affected around it and whether a local repair or wider work gives the sounder result.
