FAQs
What causes roof valley leaks on properties in Newport?
In Newport, roof valley leaks are most commonly caused by the city’s frequent wind-driven rain, aging or improperly installed lead or GRP (fibreglass) valley liners, cracked mortar, and the build-up of debris that traps moisture. Over time, UV exposure and temperature fluctuations can also cause the metal flashing or felt beneath the tiles to deteriorate, creating gaps where water can seep through.
What warning signs should I look for to know my roof valley is leaking?
Typical indicators include damp patches or brown stains on ceilings directly below the valley line, peeling paint or bubbling plaster on upstairs walls, visible daylight through the valley when you’re in the loft, and moss or debris pushed into the valley channel. Externally, you might spot slipped, broken or missing tiles around the valley or rust/staining on the lead flashing.
Do I need a full roof replacement, or can you just repair the leaking valley?
In most cases, only the affected valley section needs repairing. We can often strip back tiles along the valley line, replace damaged felt, flashings or liners, and reinstate sound tiles. A full re-roof is only recommended if widespread deterioration is found in surrounding areas or the covering is at the end of its service life.
How do you fix a leaking roof valley?
Our Newport roofing team will first erect safe access and remove tiles along either side of the valley. We then clear debris, inspect the timber valley boards, and replace any rotten sections. Next, we install a new breathable underlay, fit a high-quality GRP or code-4 lead valley liner, and reinstate or replace tiles, ensuring a secure mortar-free finish where possible to conform with modern standards. Finally, we water-test the valley before leaving site.
How much does a typical roof valley repair cost in Newport?
Costs vary with roof pitch, access and the length of the valley, but most straightforward repairs in Newport fall between £350 and £750 per valley, including materials, labour and waste disposal. Complex roofs, slate coverings or the need for scaffolding can push the price higher. We provide free, no-obligation surveys and written quotes so you know the exact figure before work starts.
Will my home insurance cover a leaking roof valley repair?
Insurance policies usually cover sudden storm damage but not failures due to age or wear. If high winds have lifted tiles or dislodged the valley flashing, your insurer may contribute, provided you can show evidence of regular maintenance. We can supply a detailed report and photos to support any claim, and we’re happy to liaise directly with your loss adjuster to speed up approval.
