“Excellent roofing service in Leeds. They fixed our leak quickly and explained everything clearly.”
A visible leak is not always where water is entering. We inspect the surrounding roof area to find the source before recommending a repair.
If a sound roof can be repaired effectively, we will not recommend replacing the whole system simply to increase the size of the job.
You will know what needs repairing, what work is proposed and what the quoted price covers before the repair begins.
Edges, outlets, upstands and junctions are checked alongside the damaged area because small defects in these places can lead to recurring leaks.

Flat roof problems are often easier to deal with when they are identified early. Changes inside the property or on the roof surface can indicate that the waterproofing, drainage or roof details need attention.
Damp ceilings, staining or moisture around the roof area can indicate water getting through the flat roof covering. The visible damp patch may not always be directly below the point where water is entering.
Water that remains on a flat roof after rainfall may indicate poor falls, blocked outlets or low areas in the roof surface. Persistent ponding can place additional stress on the roofing system.
Cracking, splitting or blistering in felt or other flat roof coverings can weaken the waterproof layer and increase the risk of water getting beneath the surface.
A leak that keeps returning after previous repairs may indicate a wider issue with the membrane, flashing, drainage or underlying roof deck. Recurring leaks should be inspected promptly, as leaving a roof leak untreated can lead to further damage to insulation, ceilings and other parts of the property.
Flat roof repair costs can vary depending on the problem and the amount of work required. Use the table below as a general guide to compare common repair types and what can affect the final price.
| Repair Type | Typical Cost Range | What Can Affect the Cost |
|---|---|---|
| Minor Leak or Patch Repair | £100–£250 | Leak location, size of damaged area and roof access |
| Felt Roof Repair | £150–£400 | Splits, blistering, failed joints and amount of felt affected |
| EPDM Roof Repair | £150–£450 | Punctures, seam failure, edge damage and repair size |
| GRP Fibreglass Repair | £180–£500 | Cracking, surface damage, joints and damaged detailing |
| Flashing Repair | £150–£400 | Location, condition of existing flashing and access |
| Drainage or Outlet Repair | £150–£350 | Blockages, damaged outlets and surrounding membrane condition |
| Roof Deck Repair | £300–£700+ | Amount of rotten or water-damaged decking beneath the covering |
| Larger Flat Roof Repair | £500–£1,500+ | Roof area, materials, underlying damage and complexity |
The final cost depends on more than the visible damage. Roof access, the roofing system, the size of the affected area and whether water has reached the deck or insulation can all influence the amount of work required.
Note: These are indicative price ranges rather than fixed quotations. The roof should be inspected before an accurate repair price is provided.
The cost depends on the roofing system, extent of damage, access and whether the problem affects only the waterproof covering or the roof deck beneath it. An inspection is the best way to provide an accurate repair quote.
Often, yes. Localised leaks caused by damaged felt, membrane seams, flashing or small punctures may be repairable. If the roof has widespread deterioration or significant structural damage, roof replacement may be more practical. This is particularly worth considering when repeated repairs are becoming costly or the existing roofing system is approaching the end of its service life.
Common causes include cracked or split membranes, deteriorated felt, failed seams, damaged flashing, blocked outlets, ponding water and ageing roofing materials.
Yes. Felt roof repairs can address splits, cracks, blistering, failed joints and other localised damage where the existing roof remains suitable for repair.
Yes. EPDM flat roofs can often be repaired where there are localised punctures, tears, failed seams or problems around edges and roof penetrations.
Localised cracks and damaged sections of GRP roofing may be repairable depending on the condition and extent of the damage. The roof should first be inspected to determine the appropriate repair.
Ponding water can result from inadequate falls, blocked drainage outlets, roof movement or low areas in the roof surface. The underlying cause should be identified rather than simply treating the visible water.
Yes. Failed flashing and detailing around walls, parapets, chimneys and upstands can allow water beneath the roof covering and may require repair or replacement.
Emergency repairs can be used for active leaks and weather-related damage where prompt action is needed to reduce further water ingress. The permanent repair required will depend on the roof’s condition.
A localised problem on an otherwise sound roof may only require repair. Replacement becomes more likely when there is widespread deterioration, repeated leaking, extensive decking damage or the roof has reached the end of its practical service life.
