The first step in fixing a roof leak is to identify the leak's origin by looking for any missing or broken shingles on the roof. Clear the area of any debris so that the problem may be seen clearly. For minor gaps or cracks, use roofing cement or sealer. Remove any broken shingles and install new ones, being careful to fasten them with roofing nails. Use roofing adhesive to seal all edges. Examine the flashing surrounding vents or chimneys, then replace or reseal it as necessary. Lastly, make sure there is enough ventilation in the attic and look for any indications of water damage to help stop leaks in the future. https://managemyroof.com/blog/easy-roof-...
