If your roof is showing signs of trouble, catching the problem early is the difference between a small repair bill and a much larger one - here is what to look for and why it happens.
Bury St Edmunds Roofers carries out roof repairs across Stowmarket and the villages nearby. The work covers slipped tiles and slates, leaking valleys, failed flashings, open ridge joints and chimney problems. Before we quote for anything, we find out exactly where the water is getting in - because treating the symptom without understanding the cause leads to the same problem returning.
Most roof problems give warning signs before they turn into serious leaks. The difficulty is knowing which signs are urgent and which can wait a season. Below are the ones that genuinely matter.
Understanding the cause helps you ask the right questions when getting a repair quoted. Most roof failures come down to one of four things: age, movement, poor original workmanship or a previous repair that was not done properly.
Age: Plain clay and concrete tiles can last 60 years or more, but the mortar bedding them, the lead flashings and the roofing felt underneath have shorter lives. Roofing felt typically lasts 20-30 years before it becomes brittle. Lead flashings done to the correct code (Code 4 or Code 5 for most domestic applications) can last 50 years or more if dressed correctly and not damaged. If your roof is over 30 years old and has never had attention, the felt and flashings are worth checking even if you have not seen a leak yet.
Thermal movement: Roofing materials expand in summer heat and contract in cold weather. Mortar is less flexible than the tiles it holds, so repeated movement causes cracking at the ridge and on verge pointing. This is gradual, but once the first cracks appear they widen faster because water gets in, freezes and expands.
Poor workmanship: A previous repair carried out with the wrong materials or technique can fail within a few years. Common examples include using sand-and-cement mortar as a flashing fillet (instead of proper lead), or re-bedding ridge tiles without cleaning off the old crumbling mortar first. Both are short-term fixes that create longer-term problems.
Wind lift: Tiles on exposed sections - ridges, gable ends and verges - are more likely to loosen because they take the brunt of the wind. On older roofs where tiles were not clipped or nailed, the only thing holding them is their weight and the batten below. As battens rot, the fixing loosens.
Roof repair costs in the UK vary considerably depending on access, the number of tiles involved and what else is found once the problem area is stripped back. As a general guide:
These figures reflect typical UK ranges and will vary with the specifics of your property. Any quote should tell you what was found, what will be done and what materials will be used - not just a single number.
Most straightforward tile repairs, ridge repointing or flashing replacements are completed in a day. Larger areas of stripped felt and battens, or a chimney that needs repointing and flashing replacement together, can take two days. If scaffolding is required for safe access, allow time for its erection and removal around the repair itself.
A well-maintained pitched tile roof does not have a fixed replacement schedule. Clay and concrete tiles on a sound structure can last many decades. The decision to replace rather than repair usually comes when: the original felt has failed across most of the roof (not just one section), a large proportion of tiles are cracked or spalling, or the roof has been repaired multiple times in the same area without resolving the problem. A good roofer will tell you honestly which side of that line you are on rather than pushing for a full replacement when a repair will do - or patching indefinitely when replacement is the right answer.
Before agreeing to any roof repair, ask the roofer to explain what they found, where the water entry point is and what they are going to do about it. Ask whether the tiles being replaced are a match for the existing ones - mismatched tiles are a common result of repairs done in a hurry. Ask whether the felt underneath is being checked and whether the repair involves any lead or flashing work.
