You’re not thinking about your roof until water shows up on your ceiling. Or your energy bill jumps because your HVAC is working overtime to compensate for heat pouring through old shingles. Or you notice a few loose shingles after a storm and wonder if it’s going to get worse.
That’s when you need someone who understands what Alum Rock weather does to roofs. The UV exposure most of the year, then heavy rain when winter hits. The way it accelerates wear on shingles, flashing, and underlayment faster than most homeowners expect.
When we handle your roof, you get a system that actually does its job. Your home stays dry. Your energy bills drop because your home stays cooler naturally. You stop wondering if the next storm is going to cause problems.
We’ve been working in Santa Clara County since 1985. We know the neighborhoods, the building codes, and what holds up in this climate. When you call us, you’re getting a licensed, insured roofing contractor who pulls the right permits and follows codes. No shortcuts. No surprises later when you try to sell your home or file an insurance claim.
We started as an HVAC company in 1985. Homeowners kept asking us to handle their roofs too, so we expanded. That’s how we’ve been doing this for 40 years—showing up when we say we will, doing the work right, and being here when you need us again.
Alum Rock has changed a lot in that time. Property values have climbed. The tech boom brought new homeowners who expect quality work. We know that when you’re paying what homes cost here, you need a roofer who treats your investment that way.
We’re not the cheapest option, and that’s intentional. You’re paying for a roof that lasts, installed by people who know what they’re doing. You’re paying for permits handled correctly, materials that can handle our weather, and work that won’t come back to bite you during a home sale or insurance claim.
First, we come out and inspect your roof. Not just the obvious problem spot, but the whole system. We’re looking at shingles, flashing, ventilation, underlayment, and any signs of water intrusion. You get a clear explanation of what’s wrong and what it’ll take to fix it.
If you need a full replacement, we handle the permit application. San Jose requires permits for all roof replacements and most major repairs. Some homeowners try to skip this to save money, but that’s a mistake. If you ever sell your home, unpermitted work shows up in title searches and can kill a sale. Insurance companies can also deny claims if they find out your roof wasn’t permitted. We handle this as part of our service—you don’t need to deal with the city yourself.
Once permits are approved, we schedule the work. We remove your old roofing, inspect the decking for damage, replace anything that’s compromised, install new underlayment and flashing, then put down your new roof. We clean up completely—no nails left in your driveway, no debris in your yard.
After installation, we do a final walkthrough with you, make sure you understand your warranty, and give you our contact information. Most roofs we install don’t need attention for years, but if you have questions, we’re still here.

We handle asphalt shingles, metal roofing, and tile—whatever makes sense for your home and budget. Asphalt composition shingles are the most common here. They’re cost-effective and typically last 15-20 years in our climate before needing replacement. Metal roofing costs more upfront but lasts longer and reflects heat better, which can help with energy costs during our hot summers.
The permit process ensures your new roof meets current building codes, including fire resistance ratings and proper ventilation. This protects you by making sure everything’s installed correctly and up to code. It also protects your home’s resale value and keeps your insurance valid.
Alum Rock gets the same weather patterns as the rest of San Jose—dry, hot summers and wet winters. That cycle is hard on roofs. The UV exposure breaks down shingles over time. The rain tests your flashing and underlayment. If your roof is more than 15 years old and you’re seeing signs of wear, it’s worth getting it inspected before small problems turn into water damage inside your home.
We also handle emergency repairs. If a storm damages your roof and you need immediate help, we’re available 24/7. Water damage gets worse fast, so getting a tarp up or temporary repairs done quickly can save you thousands in interior damage.
Most residential roof replacements take one to three days, depending on the size of your home and the complexity of the roof. A straightforward single-story home with a simple roofline usually gets done in a day. Two-story homes or homes with multiple roof planes, chimneys, or skylights take longer.
Weather can affect the timeline. We don’t install roofing in the rain because moisture trapped under new shingles causes problems later. If rain is forecasted, we’ll reschedule rather than rush and compromise the quality of your roof.
The permit process adds time before we start work. San Jose typically processes roofing permits within a few days to a week, but it can take longer during busy seasons. We submit your permit application as soon as you approve the proposal, so the timeline starts running immediately. Once the permit is approved, we schedule your installation based on our availability and yours.
Yes. San Jose requires permits for all roof replacements and most major repairs. This isn’t just bureaucracy—it’s protection for you as the homeowner.
The permit process ensures your roof meets current building codes, including fire resistance requirements, proper ventilation, and structural standards. An inspector comes out after installation to verify everything was done correctly. That inspection report becomes part of your home’s record.
When you sell your home, title companies search for unpermitted work. If they find a roof replacement that wasn’t permitted, it can delay or kill your sale. Buyers get nervous about unpermitted work because they don’t know if it was done correctly. Insurance companies can also deny claims if they discover your roof wasn’t permitted and doesn’t meet code. We handle the entire permit process for you—application, fees, scheduling inspections, and making sure everything passes. It’s included in our service.
Asphalt composition shingles are the most common choice here. They handle our climate well, meet fire resistance requirements, and cost less than other options. You can expect 15-20 years from quality asphalt shingles in our climate before they need replacement.
Metal roofing is becoming more popular, especially for homeowners concerned about energy costs. Metal reflects heat instead of absorbing it, which keeps your attic cooler during summer. It costs more upfront but lasts 40-50 years and requires less maintenance. Metal is also more fire-resistant, which matters in California.
Tile roofing is another option, particularly on Spanish-style homes where it matches the architecture. Tile lasts a long time and handles our weather well, but it’s heavy. Your roof structure needs to be able to support the weight. Tile also costs more than asphalt, both for materials and installation.
We’ll walk you through the options based on your home, your budget, and what matters most to you—whether that’s upfront cost, long-term durability, energy efficiency, or appearance.
It depends on the age of your roof, the extent of damage, and what’s causing the problem. If your roof is under 10 years old and you have isolated damage—a few missing shingles from wind, a small leak around flashing—repair usually makes sense.
If your roof is over 15 years old and you’re seeing multiple issues, replacement is often the better investment. Shingles that are curling, cracking, or losing granules across large sections of the roof are telling you the material is wearing out. Patching one area doesn’t fix the underlying problem that the whole roof is aging.
Water stains on your ceiling are a red flag. By the time water shows up inside, it’s been getting into your roof structure for a while. We need to inspect not just the surface but the underlayment and decking to see how far the damage goes.
During our inspection, we’ll give you an honest assessment. If repair makes sense, we’ll tell you. If you’re going to be calling us back in a year or two for more problems, we’ll recommend replacement and explain why. You get the information you need to make the right decision for your situation.
Once your new roof is fully installed, rain isn’t a problem. The roof is designed to shed water immediately. That’s the whole point.
The concern is rain during installation. If we’re partway through a job and rain starts, we stop work and make sure everything exposed is protected. We carry tarps and know how to secure them properly. We also watch the weather forecast closely and won’t start a job if heavy rain is expected.
Modern roofing systems have multiple layers of protection. The underlayment goes down before the shingles, and it’s waterproof on its own. Even if we haven’t finished installing shingles, the underlayment keeps water out. We make sure each day’s work ends with your home protected, whether that’s completed sections of shingles or properly secured underlayment and tarps.
If you’re worried about weather during your installation, talk to us about timing. We can schedule your roof replacement during the drier months when rain is less likely. Most homeowners in Alum Rock schedule roofing work in late spring through early fall for this reason.
Most residential roof replacements in Alum Rock run between $8,000 and $25,000, depending on the size of your home, the materials you choose, and the complexity of the roof. A small single-story home with asphalt shingles will be on the lower end. A larger two-story home with a complex roofline and premium materials will cost more.
The price includes removing your old roof, disposing of the debris, inspecting and repairing the decking if needed, installing new underlayment and flashing, putting down your new roofing material, cleanup, permits, and inspections. We don’t charge separately for permits or dump fees—it’s all included in the quote we give you.
Metal roofing costs more than asphalt—usually 50-100% more—but it lasts twice as long and can reduce your cooling costs. Tile is also more expensive than asphalt, both for materials and the labor to install it correctly.
We give you a detailed written estimate after inspecting your roof. You’ll see exactly what’s included, what materials we’re using, and what the timeline looks like. No surprises. If you need financing options, we can discuss that too. Your roof is a significant investment, and we want you to understand exactly what you’re paying for.
