What This Service Involves
Roof repairs are the most time-sensitive roofing service we provide. A leak that starts small can cause extensive damage within hours if not addressed — saturating insulation, staining ceilings, warping timber, and creating the conditions for mould growth that is expensive to remediate.
At Gwent Roofing and Building Maintenance, we provide rapid-response roof repairs for homeowners across Tredegar, Ebbw Vale, Merthyr Tydfil, Abertillery, Aberdare, Blackwood, Bargoed, Blaenavon, and Crickhowell. Whether it is a single slipped slate, a failed flashing, or significant storm damage, we diagnose the problem accurately and fix it properly.




We do not believe in temporary fixes. While we will make your roof watertight immediately in an emergency, we always follow up with a permanent repair that addresses the root cause. This means you do not pay twice — once for a patch and again when it fails.
Every repair comes with a written guarantee. We stand behind our work because we know it is done right. If a repair we have made fails, we come back and fix it at no additional cost.
The True Cost of Ignoring a Roof Leak
A small leak can cause damage out of all proportion to its size. Water follows the path of least resistance — which means it rarely drips straight down. Instead, it travels along timbers, behind plasterwork, and into wall cavities where you cannot see it. By the time a stain appears on your ceiling, the damage behind it may already be severe.
Damp timber is an invitation for wood rot and insect infestation. Wet rot spreads rapidly through softwood, weakening structural timbers that support your roof. Replacing a rotten purlin or rafter is significantly more expensive than repairing the tile or flashing that caused the leak in the first place.
Mould is another consequence that homeowners underestimate. Damp conditions in roof voids and wall cavities create the perfect environment for black mould, which can trigger respiratory problems, allergies, and other health issues — particularly in children and elderly family members.
From a financial perspective, delaying repairs always increases the final bill. A £200 repair today prevents a £2,000 problem next year. Insurance assessors also look unfavourably on damage that could have been prevented with timely maintenance.

Types of Roof Repairs We Handle
Slipped, cracked, or missing tiles and slates are the most common repair we carry out. High winds, frost damage, and age all cause fixings to fail and coverings to move. We replace individual tiles and slates with matching materials, re-nail or clip them to current standards, and check surrounding coverings for signs of further movement.
Flashing failures are the second most common cause of roof leaks. Lead flashings around chimneys, walls, and roof junctions deteriorate over time — cracking, lifting, or separating from the masonry. We remove failed flashings, prepare the joint properly, and install new code-5 lead sheet that is hand-dressed and wedged into raked-out mortar joints.
Ridge and hip tile repairs address one of the most visible signs of roof deterioration. Mortar bedding cracks and loosens over time, allowing ridge tiles to rock and eventually slip. We offer both traditional re-bedding and modern dry ridge systems. Dry ridge is our recommendation for long-term durability and storm resistance.
Flat roof repairs are common on extensions, porches, garages, and bay windows. We repair EPDM, felt, and fibreglass flat roofs — addressing splits, bubbles, failed laps, and ponding. Where a flat roof is beyond economic repair, we advise on replacement options honestly.
Valley and gutter repairs address the channels where two roof slopes meet. Valleys collect high volumes of rainwater and are prone to blockage, corrosion, and failure. We install new lead or fibreglass valleys and ensure proper falls so water drains cleanly and quickly.
We also repair and replace roof vents, soil pipe flashings, Velux window seals, and dormer cheeks. No element of your roof is outside our expertise.
