JB Roofing Company | Roofing Services in San Francisco, CA 94147

In San Francisco, the primary culprits are persistent coastal moisture, fog, and wind-driven rain. This moisture can seep under tiles or shingles, leading to wood rot in the decking beneath. Over time, this decay can compromise the fasteners holding tiles in place, causing them to slip or become loose. Regular inspections are key to catching these issues early before they lead to leaks or more extensive damage.

Our repair process starts with a thorough inspection to assess the extent of the rot. We then carefully remove the affected roofing materials to expose the damaged decking. All rotted wood is cut out and replaced with new, treated plywood or OSB that meets local building codes. Finally, we install a new underlayment and re-roof the section with matching materials, ensuring a seamless, watertight repair that restores the roof's integrity.

Yes, absolutely. We offer preventative maintenance services specifically for tile roofs. This includes re-securing loose or slipped tiles with proper, corrosion-resistant fasteners, replacing broken tiles, and checking the underlying underlayment for wear. We also recommend periodic inspections, especially after stormy seasons, to address minor issues before they escalate. Proper maintenance significantly extends the life of your tile roof in our local climate.
