When a roof problem shows up - a damp patch on the ceiling, a tile on the lawn, a dark streak down a chimney breast - most homeowners want to know two things: how serious is it, and how long before someone can look at it? We carry out roof repairs for homeowners in East Harling and the surrounding area, working out of Thetford. After the work is done, we provide a written report on the condition of the wider roof so you have a clear picture of what else might need attention.
The repairs we carry out include replacing slipped or cracked slates and tiles, re-bedding and repointing mortar ridge and hip tiles, resealing or re-dressing flashing at chimney stacks and abutments, repairing valley gutters, and repairing flat roof sections over extensions and bay windows using felt or EPDM rubber membranes.
Identifying where a leak is actually coming from is often the harder part of the job. Water entering through a faulty tile or failed flashing does not fall straight down to the room below - it travels along the underside of the roof deck, down rafters, and along battens until it finds a low point to drip from. The ceiling stain and the roof fault can be a metre or more apart, horizontally as well as vertically.
The starting point is the roof section directly above the stain. From there, the investigation moves to nearby junctions: the point where two roof planes meet, where a dormer cheek meets the main slope, where the flashing around a chimney stack meets the tiles. Extension roofs meeting the main house wall are a particularly common source of damp - the junction is rarely detailed as well as a primary roof, and the mortar or flashing there ages faster.
Clues that help trace a leak include: a dark tide mark running along the side of a chimney breast inside the loft rather than below it; wet loft insulation that is not directly under a visible gap in the tiles; staining that appears only after extended heavy rain but not a short shower; and damp at fascia level that suggests the gutter is overflowing before water even gets inside the house.
This is where many homeowners make the situation worse without meaning to. There are practical steps worth taking and others that are best left alone. Knowing the difference saves money and avoids creating new problems.
The first priority is to protect what is below the leak inside the house. Put containers under any active drip and lay down towels or plastic sheeting on the floor and on any furniture that might be affected. Move valuables out of the room if the stain is spreading. If water is pooling on a ceiling that is bowing, keep everyone out of the room and do not poke, prod or pierce it - a ceiling loaded with water is heavier than it looks and can collapse without warning.
Take photographs of the damp patch, the stain, any tide marks on walls, and anything you can see on the roof from ground level. These are genuinely useful when a roofer assesses the job - they show how the stain has changed over time and help to narrow down whether the entry point is a recent failure or a slow one that has been building up.
Check your gutters from ground level if you can do so safely. A gutter that is visibly overflowing during rain, or that has a dark waterline stain running down the fascia, may be backing water up under the lowest course of tiles. That is not always the primary cause of a leak, but it can make an existing problem significantly worse.
The temptation to get up on the roof and have a look is understandable, but a pitched roof is not a safe surface to walk on without the right footwear, equipment and experience. Tiles and slates that have shifted are also unstable - what holds your weight on the way up may not hold it on the way back down. Falls from roofs are a leading cause of serious injury in domestic settings, and a single broken tile dislodged by an inexperienced foot can create a second entry point or dislodge tiles below it.
Do not apply roofing sealant, expanding foam or tarpaulins to the roof yourself unless you are certain of what you are covering and why. Expanding foam pushed into a gap traps moisture rather than expelling it, and can cause more rot in the timber beneath than the leak it was meant to stop. A tarpaulin that is not fixed correctly can act as a sail in wind, pulling tiles with it when it lifts.
Avoid using a pressure washer anywhere near the roof or the tops of walls while the leak is active - the additional water entry will make diagnosing the source much harder and can force water into areas that were previously dry.
Inside the loft, it can be tempting to move insulation around to find the drip point. That is fine, but do not compress or permanently displace insulation that is doing its job - note what you see and photograph it, but leave the material where it is as far as possible.
The more detail you can give, the faster a roofer can assess the job and price it accurately. Useful information includes: where the damp is showing inside the house (which room, which wall, ceiling or wall junction); how long the stain has been there and whether it grows during or after rain; whether the roof has been worked on recently; whether you have a chimney stack and roughly how old the lead flashing looks; and whether the property has a flat-roof extension.
If you have noticed the drip only after very heavy sustained rain but not after a short shower, say so - that pattern is a strong diagnostic clue pointing toward a slow drainage failure rather than a straightforward gap in the tile.
Replacing a small number of broken or slipped tiles typically costs between £150 and £350 depending on tile type, roof pitch and access. Re-bedding a full mortar ridge on a semi-detached house usually falls between £400 and £800. Flashing repairs at a chimney stack range from around £150 for a re-seal to upwards of £500 for a full lead re-dress with re-pointing. Flat roof repairs over extensions vary depending on the size of the section and the membrane system in place. Every job is priced on what we actually find on the day - these are current typical UK ranges to help you budget.
If something on your roof does not look right, it is worth having a roofer take a look at it. We cover East Harling, Thetford and the surrounding villages. We will tell you plainly what needs doing, what can wait, and what to watch - in a written report you can keep.
