Roof Maintenance in National City, California

The National City coastal climate is gentle on the temperature and hard on the flashings. The salt air, the marine layer, and the winter rain each test the roof in their own way. Roof maintenance in National City catches the small problems before the coastal conditions turn them into big repairs.

Signs Your National City Roof Needs Maintenance

• Corrosion on the flashings and the vents — the salt air is eating the metal
• Moss on the shaded slopes — the coastal moisture is feeding the growth
• Debris in the gutters — the winter rain will back up the drainage
• Granules in the gutters — the shingles are shedding their surface
• The roof has not been inspected in over a year — the maintenance is overdue

Why National City Roofs Need Maintenance

The salt air from San Diego Bay corrodes the flashings and the fasteners. The corrosion is invisible from the ground, and the first sign is a leak during the winter rain.

The coastal moisture works the other way. The marine layer keeps the roof damp through the morning, and the moisture works on the sealants and the shingle edges.
