How we handle emergency roof repairs

Roof emergencies in Dereham and the surrounding villages

A roof problem that is letting water into the building needs attention before more damage is done. Water finds its way through ceilings, into wall cavities and along timber joists far faster than most people expect, and the secondary damage it causes often costs more to put right than the original roof fault. This page explains what to do the moment you suspect an emergency, how to keep safe and limit the damage, and what the repair work itself involves.

What counts as a roof emergency?

Not every roof problem needs the same level of urgency. The situations that genuinely cannot wait include an active leak during or after rain, missing or slipped tiles or slates that are leaving the roof exposed, a lifted or dislodged ridge tile, lead flashing that has pulled away from a wall or chimney and is letting water behind the mortar joint, and any visible damage after a storm.

A sagging or bulging ceiling is a serious warning sign. Water can collect above plasterboard for hours before the board gives way, and a ceiling can come down without much warning. Keep people out of the room. Do not poke, prod or pierce the ceiling, and do not try to drain it yourself. The weight of trapped water is greater than it looks.

Blocked gutters, overflowing valley gutters and blocked downpipes are a less obvious but common cause of sudden internal leaks. When water cannot get away from the roof quickly enough it backs up under tiles or finds a way through flashings and joints that would otherwise hold. If you can safely see gutters from the ground and notice them overflowing during rain, that detail is worth passing on when you call.

Keeping safe and limiting the damage

The most important rule is this: do not go on the roof yourself. A wet or frost-covered roof is extremely dangerous, and even a single-storey roof edge is high enough to cause a serious injury. Anything that needs doing at roof level must wait until a roofer with the right access equipment has assessed it.

Inside the building, contain the water. Use buckets, bowls and towels, and lay down plastic sheeting to protect floors. Move furniture, electronics and anything else of value out of the affected room. Take photographs of the damage as soon as you can.

If water is dripping near a light fitting, socket, switch or any electrical cable, do not touch it. If your consumer unit (fuse box) is dry and you can reach it without going near any water, you can turn off the main switch. If the consumer unit itself is near the leak, or if you are in any doubt, leave all electrics alone and call an electrician.

Open windows in the affected room if you can do so safely - ventilation helps dry timber and plasterboard more quickly once the leak is controlled.

Temporary make-safe work versus permanent repair

When a roofer first attends an emergency, the priority is to stop water getting in, not necessarily to complete the permanent repair in a single visit. Temporary make-safe work typically involves securing a heavy-duty tarpaulin or temporary sheeting over the damaged area, re-bedding a loose ridge tile with a mortar mix, or temporarily dressing back a lifted section of lead flashing to close the gap.

Temporary work buys time. It is not the same as a permanent repair, and it will need to be followed up. The two are sometimes invoiced separately, so ask for that distinction to be clear when you discuss the work.

Scaffolding and safe access affect what make-safe work can be done and what it costs. A slipped tile on a lower-pitch roof may be reachable with roof ladders and no scaffold. A larger area of damage, a high or steep pitch, or a problem near a parapet or flat roof edge may require scaffold before any safe work is possible. That decision is made on site, not over the phone. What affects the total cost of emergency roof work includes the extent of the damage, whether temporary or permanent work is needed, how many tiles or slates are involved, the access required, and whether structural timbers have been affected.

Common emergency faults on pitched roofs

Pitched roofs can be covered in several materials, including plain clay tiles, concrete interlocking tiles or natural slates. Each type fails in slightly different ways, and knowing which you have helps you describe the problem when you call.

Plain clay tiles are double-lapped, meaning each tile is covered by two rows of tiles above it. One missing tile does not leave a straight-through hole, but it does expose the tiles below, the battens and the underlay to wind and rain, and if the underlay has aged or split, water will reach the roof timbers. Plain clay tiles hang on nibs that hook over the battens, and they can slip or crack after frost or impact damage.

Slates slip when their fixing nails corrode and fail - a condition known as nail sickness. Slates have no nibs, so once a nail fails the slate can slide down or fall. Like plain clay tiles, slates are double-lapped. A cluster of slipped slates in the same area of a roof usually means the nails in that section have reached the end of their useful life, and patching individual slates may not solve the underlying problem. A roofer should check the surrounding slates and the nail condition when attending.

Concrete interlocking tiles are single-lapped. Each tile seals against its neighbours with an interlocking profile, so one missing or cracked tile can leave a more direct path for water than a missing slate or plain clay tile. Lifted or cracked interlocking tiles after a storm should be checked across the whole slope, not just at the visible damage.

Ridge tiles on older roofs are mortar-bedded onto the apex of the roof. The mortar can crack after frost or simply dry out and shrink over time. A ridge tile that has rocked loose or lifted is a hazard - the tile itself can fall and cause injury, and the gap it leaves lets water straight into the ridge. Newer roofs often use a dry-fix ridge system with mechanical fixings, which is generally more reliable in exposed conditions. When a mortar-bedded ridge tile has failed, the surrounding mortar bed should be checked as well as the single loose piece.

Lead flashings seal the join between the roof and a chimney, a wall or the side of a dormer. Lifted lead can sometimes be dressed back into position and re-secured. Cracked or split lead cannot be dressed back and needs to be replaced. The mortar joint that holds the top edge of the flashing should be checked at the same time - if the mortar has failed, re-fixing the lead alone will not give a lasting result.

Common emergency faults on flat roofs

Flat roofs can be finished in several materials, including traditional felt and EPDM rubber membrane. Both can fail suddenly as well as through gradual wear.

A split or lifted membrane lets water through directly. EPDM that has pulled away where it turns up a wall or at the roof edge will allow water to run down behind the fascia or into the wall below. Felt that has cracked at a seam or blister point fails in the same way. Temporary sheeting is harder to secure properly on a flat roof than on a pitched one, so the permanent repair matters even more.

Standing water on a flat roof points to a different problem: a blocked outlet or insufficient fall (the slight slope built into the deck to take water to the drain). Standing water does not always cause an immediate leak, but it adds weight to the deck and accelerates membrane wear. If you can see standing water on a flat roof from the ground, mention it when you call.

After the leak: checking the structure

Once the source of a leak is repaired, the work does not end at the visible fault. Water that has entered through a gap in tiles, a failed flashing or a split membrane may have been sitting in the roof space for longer than the visible internal staining suggests. The underlay, battens and roof timbers beneath the repair area should all be checked for moisture damage, rot and insect or fungal activity.

Not all older roofs have underlay. On those roofs, a missing or slipped tile leaves the battens and timbers exposed without any secondary layer to slow the water. If your property is older and you are unsure whether it has underlay, it is worth asking a roofer to check when they attend.

Battens sit on top of the underlay. Water that gets through a gap in the tiles reaches the battens and underlay together. Waterlogged battens can swell, crack and eventually fail to hold tile fixings properly, which increases the risk of further slippage. Rotted or damaged battens in the repair area should be replaced as part of a permanent fix, not left in place behind new tiles.

Storm damage and buildings insurance

Storm damage to a roof is often covered by buildings insurance, but the claims process has several stages where a payout can be reduced or refused. Photograph the damage as soon as it is safe to do so, note the date and time, and keep any receipts for emergency work. Report the damage to your insurer as soon as possible - most policies have a requirement to notify within a reasonable time.

Insurers typically define a storm by recorded wind speed or rainfall, and each policy sets its own threshold. A claim can be declined if the insurer decides the storm only exposed existing wear and tear rather than causing the damage directly. This is a common reason for refused claims on older roofs. If your claim is refused, you can go through the insurer's formal complaints process and, if that does not resolve it, take the matter to the Financial Ombudsman Service.

Keep the repair and the insurance claim separate in your mind. A make-safe repair needs to happen to protect the building. Do not delay essential emergency work waiting for an insurer to send a loss adjuster if water is actively getting in. Document what was done, by whom and when, and keep all paperwork.

What happens when you call Dereham Roofers

Calls are answered day and night and passed straight to our roofers, who ring you back to talk through what has happened and arrange a visit.

When you call, it helps to have ready: the address, a description of what you can see (or hear), whether there is active water coming in, and whether there is any known access issue such as a tall or steep roof or restricted vehicle access. If you have already taken photographs, keep them to hand.

When a roofer attends they will check the fault and explain what needs doing to make the roof safe. They will tell you what is a temporary measure and what is a permanent repair, and what will affect the cost.
