FAQ

Your Roofing Questions, Answered

Roofing repair is one of the most common types of home improvement projects. Find out what you should know before starting your project. Projections show that the global roofing market will reach a value of $156 billion by 2030. No matter how well designed and built a roof is, it will always degrade with time. It may be possible to extend the lifespan of your roof with routine maintenance, but eventually, any roof will need replacing-the question is: when? In this guide, we'll cover various roofing repair questions so you'll know what signs to look for in a damaged roof, when you should repair it, what options you have, and more.

1. Do I need a permit to replace my roof in San Jose?

Yes—full replacements (re-roofs) typically require a building permit; small spot repairs often don’t. We pull the permit and schedule inspections with the City of San José. Explore more services on our site to find what suits you best.

Most roof replacements take 1–3 days depending on size, material, and weather. Our roofing contractors  works efficiently to minimize disruption. Get a free estimate to understand your project’s timeline and scope.

A typical replacement runs about $800–$1,300 per square (100 sq ft), depending on layers, wood repairs, roof pitch, and ventilation. Many single-family homes total $20k–$45k+. An on-site inspection gives the most accurate price.. Schedule your inspection today to get started with expert insights.

Architectural asphalt shingles are the best value; tile is common, but the underlayment often needs renewal after 20–30 years. Choose Class A fire-rated materials and ensure proper attic ventilation. Explore our service areas to check if we’re available near your home or business.

Sometimes allowed, but a full tear-off is usually better. It exposes damaged decking, updates flashing, and helps warranties and ventilation—leading to a longer-lasting roof. If you’re unsure, contact us today for a professional consultation and honest recommendations tailored to your situation.

Replace if you see widespread granule loss, curled/brittle shingles, chronic leaks at valleys or penetrations, or if the roof is near its expected lifespan. Isolated leaks or a few damaged shingles can often be repaired.

Architectural asphalt: 20–30 years with good ventilation. Tile roofs can last decades, but underlayment typically needs replacement around 20–30 years.

Architectural asphalt: 20–30 years with good ventilation. Tile roofs can last decades, but underlayment typically needs replacement around 20–30 years.

California energy rules often require or encourage cool-rated shingles on certain projects. Cool roofs help reduce attic heat and AC use. We’ll confirm code path during the estimate.

If your roof is 10+ years old or near end of life, replace it before installing solar to avoid removing panels later. We coordinate scheduling with solar providers.
