Regular Inspection: Carry out regular inspections of the roof to identify any signs of damage, wear or failures in the waterproofing. This may include cracks, bubbles, areas of stagnant water, or spots where the seal appears compromised.

Localized Repair: If you identify specific problem areas, such as cracks or holes, carry out immediate repairs. This may involve filling cracks with appropriate sealants or replacing damaged parts.

Replacement of Damaged Materials: If roofing materials are damaged and cannot be repaired effectively, they may need to be replaced. This includes replacing compromised waterproof membranes, shingles, or other components.

Improvement in Drainage: Inadequate drainage problems can contribute to infiltrations. Make sure drainage systems, such as gutters and storm drains, are clean and working properly. Also consider installing additional systems if necessary.

Additional Waterproofing: If the existing waterproofing is compromised, consider applying additional layers of waterproofing. This can be done using liquid membranes, asphalt blankets, or other suitable materials.

Consult Professionals: If infiltrations persist or if the problem is extensive, it is advisable to consult professionals specialized in waterproofing and roofing. Civil engineers, architects and specialist companies can provide accurate assessments and personalized solutions.

Preventive Maintenance: In addition to reactive repairs, implement preventive maintenance practices. This includes carrying out regular inspections, cleaning gutters and downspouts, and promptly repairing any problems identified.

Remember that regular prevention and maintenance are essential to prevent infiltration and extend the useful life of the roof. The specific approach will depend on the conditions of the roof, the type of material used and the severity of the infiltrations.

In more complex situations, it is always recommended to seek guidance from specialized professionals.
