Describe the leak or damaged area
Note where water appears and when, along with visible punctures, cracks or edge defects. The indoor stain may not identify the entry point. Repeated leakage after previous patches is useful information: it may suggest an unresolved junction, drainage or underlying problem.
Match the repair to the existing system
Felt, EPDM and GRP need repair materials compatible with their existing systems. A product suitable for one covering may be unsuitable for another. Ask how the roof material was identified and why the proposed repair is appropriate to its condition.
Check underlying and drainage issues
Check whether water retention, damp underlying layers or deck damage contributes to the fault. Repairing the surface alone may leave those issues unresolved. Concealed conditions should be recognised as a limit of the initial assessment and addressed in the proposed scope.
Assess repair limits
An isolated defect in suitable surrounding material may justify repair. Extensive deterioration or repeated faults across the roof deserves a wider comparison with renewal. Ask what the repair is intended to achieve and which existing weaknesses would remain.
Prepare a repair enquiry
Provide the roof history, known covering and any earlier repair information. Describe the use of the space beneath and whether water is actively entering. Safe photos of a wider roof area can help place a small defect in context.
Your questions, answered.
Can felt, EPDM and GRP roofs all be repaired?+
They may be repairable using compatible methods, depending on the cause and condition of the roof.
Why might repeated patches fail to resolve a leak?+
The patch may not address the source, or wider deterioration and drainage issues may remain.
Will the deck need checking before a repair?+
Yes, its condition may affect whether a surface repair is appropriate, although some areas may initially be concealed.
