Balcony Roofing Repair
A leak at the door threshold is the most common balcony failure, we find it and fix the waterproofing properly, not just the symptom.
Balcony leaks tend to follow a pattern: a perished or failed membrane at the door threshold (the single most common balcony leak point), standing water from inadequate falls, blocked or undersized drainage outlets, or decking that's delaminating over a failed waterproof layer underneath.
Sherford Roofing repairs balcony waterproofing across Plymouth and Devon, diagnosing whether the issue is the membrane itself, the falls, or the drainage before recommending a fix.
Our Process
Inspect the Deck
We check the membrane, threshold, falls and drainage to find where water is actually getting in.
Diagnose the Cause
Membrane failure, poor falls, or blocked drainage are identified, each needs a different repair.
Repair or Re-Waterproof
Localised membrane failure is repaired; widespread failure calls for stripping back and re-waterproofing the deck.
Refinish
Decking or paving is reinstated over the repaired waterproofing.
