Roof Repairs & Maintenance
in Bishop's Stortford & Hertfordshire
Slipped tiles, perished mortar, lead flashing, ridge re-bedding and full leak diagnostics — repaired properly by a CRC certified roofer with 25 years on UK domestic roofs.
Overview
Diagnose First. Quote Honestly. Repair Properly.
Most roof leaks aren't actually the roof. They're failed flashing, perished mortar bedding, blocked valleys, broken slates around chimney upstands, or aged felt at the eaves. Quoting a £10,000 re-roof for a £400 problem is one of the most common pieces of bad advice UK homeowners receive.
Our roof repair service starts with a proper survey — physically up on the roof where needed, not from the ground with binoculars. We diagnose the actual cause, recommend the proportionate fix, and quote honestly. Where a repair will hold for another decade, we'll say so. Where it genuinely needs replacing, we'll explain exactly why with options at different price points.
Why It Matters
What Happens When You Ignore a Small Roof Issue
Roofs rarely fail catastrophically. They fail incrementally — a slipped tile here, perished pointing on a chimney upstand there, a hairline crack in lead flashing. Each one lets a small amount of water in, which over months degrades the roofing felt, rots the timber battens beneath, and stains ceilings before anyone notices.
By the time damp shows on a ceiling, water has typically been entering the roof structure for 6–18 months. The repair that would have cost £200 if caught early routinely escalates to £2,000+ once timber replacement, plasterboard repair and redecoration are included. If you've spotted anything off — call us early, not late.

Technical Detail
The Most Common Roof Repair Issues We See in Hertfordshire
Slipped or broken tiles and slates are the most common call-out, usually caused by perished nails (nail fatigue) on roofs 30+ years old, or by storm damage. Replacing individual tiles is straightforward — but if multiple tiles are slipping across the roof, nail fatigue is widespread and a re-roof becomes the better long-term answer.
Failed lead flashing around chimneys, valleys and abutments is the second most common issue. Lead becomes brittle with age, mortar bedding perishes, and water tracks behind the lead into the roof structure. Proper repair means stripping back, re-dressing the lead, and re-pointing with the correct mortar mix — not a smear of mastic.
Ridge tile re-bedding — older ridges bedded on lime mortar eventually let go in high winds. Modern best practice is to re-bed with a roll-out dry ridge system, mechanically fixed, which removes the long-term failure mode entirely. We recommend this on most ridge work we quote.
Other regular jobs include verge repairs, soaker replacement, valley clearance and re-bedding, and chimney pot reseating. See our chimney repair service and emergency roof repairs for related work.
