See our emergency roof repair service 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. Our Process ## How We Deliver Roof Repairs & Maintenance 01 ### Site Visit & Survey We physically inspect the roof, identify the actual cause of the issue, and photograph anything you can't see from the ground. 02 ### Honest Diagnosis We tell you exactly what we've found, what's causing the problem, and whether repair or replacement is the right answer. 03 ### Written Quote Itemised written quote covering materials, labour, scaffold (if needed) and a realistic timescale. No hidden extras. 04 ### Repair Works Proper materials, proper access, proper detailing. Most repairs completed inside a single day. 05 ### Final Check & Guarantee Final inspection from above and below, and a contractor who answers the phone afterwards.

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. Slipped tile replacement — one of the most common repair call-outs across Hertfordshire and Essex. Honest Pricing ## How Much Does a Roof Repair Cost in Hertfordshire? Repair costs vary widely with access, scaffolding need, and what the survey actually finds. Honest guide ranges below. Small repair (1–3 tiles) £150–£350 Replacement of slipped or broken tiles, accessible from a ladder, no scaffold needed. Flashing / ridge work £400–£1,200 Lead flashing repair or replacement, ridge re-bedding, valley work — usually scaffold required. Larger repair / partial re-roof £1,500–£4,500 Multiple slipped tile areas, partial re-felt, batten replacement on one side of a pitched roof. ### What affects the price - Roof height and accessibility - Whether scaffolding is required - Material type (concrete tile, clay, natural slate) - Extent of underlying damage - Lead vs lead-alternative for flashing - Number of separate repair points Get Your Free Written Quote Service Area ## Areas We Cover for Roof Repairs & Maintenance We deliver this service across our full Hertfordshire and Essex catchment.
