Question Answers

My roof ridge tiles are shifting and the underlayment seems worn. Is this a common issue in San Jose, and how do you fix it?

Yes, the combination of our sun exposure, occasional high winds, and temperature fluctuations in San Jose can cause roof ridge tile movement and underlayment deterioration over time. At Alum Rock Roofing, we address this by first conducting a thorough inspection to assess the full extent of the damage. We then carefully reset or replace compromised ridge tiles using proper fastening techniques for our local conditions and install new, high-quality underlayment designed to withstand the Bay Area's specific climate, ensuring a secure and long-lasting repair.

What does your roof inspection service include, and how often should I have one?

Our comprehensive roof inspection covers everything from shingles and flashing to gutters, vents, and the internal attic space for signs of moisture or damage. For San Jose homes, we recommend a professional inspection at least once every two years, and always after a major storm. With over two decades of local experience, we know what to look for, such as the early signs of underlayment wear or tile movement common in our area. This proactive approach helps identify small issues before they become major, costly repairs.

I need new gutters. What is the process for gutter installation or replacement?

Our process begins with an evaluation of your home's specific needs, considering roof pitch and local rainfall patterns. We then help you select the right materials and sizing for optimal water flow away from your foundation. Our skilled team handles the entire installation, from precise measurements and secure mounting to ensuring proper downspout placement. We focus on a clean, seamless fit that protects your home's exterior and complements its appearance, all while minimizing disruption to your daily routine.
