South of Seminary is one of the few neighborhoods on the Peninsula where you’ll find 1940s-era single-story homes sitting a few blocks from a mid-1990s planned community. That mix matters when it comes to roofing, because the challenges are completely different. The older homes along Coleman Avenue and Nash Avenue have original roof decking that’s been through decades of Peninsula fog, seasonal rain, and debris from the neighborhood’s mature oaks and redwoods. By the time a leak shows up on the ceiling, the damage underneath has usually been building for years.
Vintage Oaks is a different story, but not a better one. Those homes were built on the former St. Patrick’s Seminary grounds in the mid-1990s, which means original composition shingles are now 27 to 30 years old — right at the end of their typical service life. Many homeowners there are facing their first full roof replacement without any prior contractor relationship to lean on. That’s a stressful position to be in on a property worth over two million dollars.
What a properly replaced or repaired roof actually gives you is straightforward: no water intrusion during the October-through-April wet season, no ceiling stains, no compromised insulation, and no emergency calls in the middle of a storm. It also means your home’s insurability stays intact — something that matters significantly in a ZIP code where unlicensed roofing work can void your homeowner’s policy and leave you exposed on a high-value asset.
Eco Air Home Services LLC has been working in San Mateo County since 1985 — which means we were serving Peninsula homeowners before the Vintage Oaks development was ever built on those 46 acres of seminary land. Ramiro’s father started this company, and Ramiro took it over in 2006. The same commitment to doing the job right has carried through every decade in between. This is not a franchise. There is no call center. When you reach out, you are talking to people who have been in this county long enough to know the difference between a City of Menlo Park permit and a San Mateo County permit — and that distinction matters depending on exactly where your property sits in South of Seminary or the surrounding area.
We hold a California CSLB C-39 Roofing Contractor License, carry full bonding and general liability insurance, and our technicians are long-tenured professionals who have seen the full range of what Peninsula roofs go through. We also offer a 15% discount for senior homeowners — because a lot of the people who have called South of Seminary home for 30 or 40 years deserve that acknowledgment.
It starts with a call. You describe what you’re seeing — a stain on the ceiling, missing shingles after a wind event, a gutter pulling away from the fascia — and we schedule an inspection at a time that works for you. During the inspection, we assess the full roof, not just the visible symptom. In South of Seminary’s older homes, what looks like a single leak point is often the result of failed flashing around a chimney, deteriorated underlayment, or decades of moss growth that has lifted shingles from the deck. We find the actual source.
After the inspection, you get a clear explanation of what we found and what your options are. If it’s a repair, we tell you what the repair involves and how long it should hold. If it’s a full replacement, we walk you through materials, timeline, and what the permit process looks like for your specific property. That last part matters here — properties in the incorporated sections of Menlo Park go through the City of Menlo Park Building Division, while homes in the unincorporated Menlo Oaks area require a permit through the San Mateo County Development Review Center in Redwood City. We handle that process for you either way.
Once work begins, we protect your landscaping and surrounding property throughout the job. South of Seminary’s small lots and established gardens require real care during a roofing project, and we treat the site accordingly. Final walkthrough happens before we leave — you see the finished work, and we make sure you understand what was done and why.

The roofing services we provide in South of Seminary and Vintage Oaks cover the full range of what homeowners here actually run into. Residential roofing services include full roof replacements, re-roofing, and repairs for both the mid-century homes in South of Seminary and the planned community homes in Vintage Oaks. For older homes, that often means addressing original wood decking, outdated flashing systems, and underlayment that has long since exceeded its service life. For Vintage Oaks homes, it typically means a first full replacement with modern Class A fire-rated materials that meet current California Title 24 requirements — including the solar zone designations now required on all new roofing work within Menlo Park city limits.
Emergency roof repair and tarping services for leaking roofs are available when Peninsula storms move through faster than expected. If you have an active leak during the wet season, a fast tarp installation can prevent thousands of dollars of interior damage while a permanent repair is scheduled. Storm damage roof inspections are also available after significant wind events — the mature oak and eucalyptus canopy throughout the neighborhood creates real debris and branch-impact risk that is worth assessing after any major storm system.
For commercial roofing services in San Mateo County, we work with property owners and managers across the county on both flat and pitched commercial roof systems. Every job — residential or commercial — is permitted, inspected, and completed by licensed professionals who know this county’s specific code requirements.
Yes, and the answer is slightly more complicated here than in most Bay Area neighborhoods because of how this area is governed. If your property is within the incorporated limits of the City of Menlo Park, your re-roof permit goes through the City of Menlo Park Building Division, which lists residential reroofs as a standard permit category that can be submitted online. If your property is in the unincorporated Menlo Oaks area — which includes portions of the broader South of Seminary neighborhood — your permit is issued by the San Mateo County Development Review Center at 455 County Center in Redwood City.
The practical difference is that these are two separate agencies with separate application processes, and submitting to the wrong one causes delays. We handle permit pulling for every job we do in this area, and we know exactly which authority applies to your address before we ever schedule the work. You don’t need to figure this out on your own.
The homes in Vintage Oaks were built in the mid-1990s, which puts most of them at 27 to 31 years old right now. Standard composition shingles — the most common roofing material used in that development — have a typical service life of 25 to 30 years. So if your home still has its original roof, you are statistically at or past the point where repairs become a short-term solution to a whole-system problem.
The honest answer is that a repair makes sense when the underlying deck and underlayment are still in good condition and the damage is genuinely isolated. But when shingles are brittle, granule loss is significant, and the underlayment has dried out, patching one section often just shifts where the next leak shows up. During an inspection, we assess the full roof — not just the problem area — and give you a straight answer about whether a repair will actually hold or whether a replacement is the more cost-effective move over the next five to ten years.
The Peninsula’s climate — consistent summer fog, concentrated winter rainfall from October through April, and a mature tree canopy that keeps roofs shaded and damp — creates specific wear patterns that not all roofing materials handle equally well. Asphalt shingles are the most common choice and work well when they are Class A fire-rated and algae-resistant, which matters in a neighborhood where shade and moisture accelerate moss and algae growth on roof surfaces. Concrete tile is another strong option for the area — it handles the wet-dry seasonal cycle well and has a long service life, though it requires verified structural support given its weight.
Wood shakes, which are still present on some of South of Seminary’s older homes, are increasingly problematic from a California fire code standpoint and are typically replaced with Class A-rated alternatives during re-roofing. Metal roofing is a durable long-term option that handles fog and rain exceptionally well, though it carries a higher upfront cost. We discuss material options during every inspection and recommend based on your specific roof structure, budget, and how long you plan to stay in the home.
In the San Mateo County market, residential roof replacement costs generally range from $10,000 to $25,000 or more for a standard single-family home, depending on roof size, pitch, material selection, and the condition of the underlying deck. South of Seminary’s single-story ranchers tend to have simpler roof geometries, which can keep labor costs on the lower end of that range. Vintage Oaks homes vary more in layout and may have additional complexity around dormers, skylights, or solar-ready zones that affect the final number.
What affects cost most significantly is what gets discovered once the old roofing is removed. If the decking underneath has rot or structural damage — which is not uncommon in homes built in the 1940s and 1950s — that adds material and labor to the project. We identify as much of this as possible during the inspection, and we do not give you a number that changes dramatically once work starts without a clear explanation of why. Transparent pricing is not a policy here — it is just how a 40-year-old business stays in business.
When the Peninsula’s atmospheric rivers roll in during the wet season, they can push a marginal roof past its limit in a matter of hours. Active leaks do not wait for business hours, and interior water damage compounds quickly — soaked insulation, damaged drywall, and compromised flooring can turn a roofing problem into a full interior restoration project if left unaddressed overnight.
We provide emergency roof repair and tarping services for leaking roofs in South of Seminary and Vintage Oaks and prioritize response when a roof is actively letting water in. Tarping is a legitimate first response — it stops the water intrusion immediately and protects the interior while a proper assessment and permanent repair are scheduled. If you are seeing water come in during a storm or you have discovered damage after a wind event, call us directly. We will tell you honestly what the fastest and most protective path forward looks like for your specific situation.
Yes — 15% off for senior homeowners, applied to roofing services. South of Seminary is a neighborhood with some of the lowest residential turnover on the Peninsula, which means a significant portion of the people living there have owned their homes for 20, 30, or even 40 years. Many of them are now at or past retirement age, and they are also the homeowners most likely to be sitting on a roof that is well past its replacement window — because the home they bought in 1982 probably had a roof done in the late 1980s or early 1990s that has not been touched since.
The discount is straightforward: if you qualify, it comes off the total. It applies whether the job is a repair or a full replacement. We also offer the same 15% discount for active military and veterans. These are communities that have invested in this Peninsula for decades, and the discount reflects that. If you are a senior homeowner in South of Seminary or Vintage Oaks and you have been putting off a roof inspection because you were not sure who to call, this is a reasonable place to start.
