Fast, Reliable Roof Inspection Across Sunnyvale
A roof inspection in Sunnyvale typically costs $180 – $340 for a standard visual and moisture scan, and most inspections in our area can be scheduled within a few business days. If you own a mid-century Eichler in Cherryhill or Fairbrae, or a flat-roof workhorse near El Camino Real, the inspection is different from what a shingle-roof house needs. Call (361) 320-9467 and we’ll schedule a real inspection by a background-checked, uniformed technician who knows Sunnyvale’s housing stock, its tree ordinance, and the radiant-heating zones that make an Eichler roof unlike anything else in the Bay Area.
Why Brennan Roofing Is Sunnyvale’s Preferred Roof Inspection Company
We’re an independently owned roofing company held to The Garrison Standard, which means the price goes on paper before any work starts, the technician who shows up is background-checked and in uniform, and every inspection is backed by a written one-year guarantee. That matters in Sunnyvale, where flat and low-slope roofs hide failures that a quick walk-around misses. Our crew works on Eichler tracts around Cherryhill, Fairbrae, and Birdland regularly. We know what saturated underlayment looks like under an old foam roof. We know where the radiant-heating pipes run. And we know what Sunnyvale’s tree ordinance requires before we set a ladder against the eave.
Homeowners in Sunnyvale call us because they’re tired of roofers who no-show or quote a number that moves at the door. The Garrison Standard exists to remove that. Your inspection price is written and fixed. The report you get is specific to what we found, not a template. And if a repair we complete fails inside the guarantee period, we come back free. That’s the 365-Day Done Right Promise, in writing, for one full year.
Roof Inspection Services in Sunnyvale
Roof Inspection Services in Sunnyvale start with a direct conversation about what you’re seeing: a stain on the ceiling, granules in the gutter, ponding water after a winter storm, or just the realization that a 1956 roof hasn’t been looked at in a decade. We walk the roof, check penetrations, seams, flashing, and drainage, and we look at the areas a generic inspection skips on a low-slope or flat Sunnyvale home. A standard inspection in Sunnyvale runs $180 – $340. If we’re inspecting after a storm or for a specific leak, we’ll tell you upfront what the visit will cost before we schedule it.
What the Inspection Covers
We examine the membrane or shingle surface, flashing at vents and curbs, drainage paths, and the condition of the decking where we can access it. On a flat foam or tar-and-gravel roof, we look for ponding zones, blistered membrane, and saturated underlayment. On a shingle or tile roof, we look for cracked or slipped units, worn sealant at penetrations, and valley debris that traps water.

When to Schedule One
Before the November rain pattern, after any atmospheric river event, or before you list a Sunnyvale home. If you’re buying a mid-century Eichler, get the inspection done before you close. The original roofs on many of those homes are past end-of-life, and the fix is not a simple shingle overlay.

Hail Damage Roof in Sunnyvale
Hail Damage Roof inspections in Sunnyvale are most common after the rare spring hailstorms that roll off the Santa Cruz Mountains and hit areas around Cupertino, Sunnyvale, and Santa Clara. Hail on a flat or low-slope roof behaves differently than hail on architectural shingles, and you won’t always see the damage from the ground. A hail-damage inspection in Sunnyvale typically falls in the same $180 – $340 range, and if you file an insurance claim, we’ll give you a written report with photos and measurements your adjuster can work from.
Flat Roof Hail Damage
On a foam, modified bitumen, or TPO membrane, hail can fracture the surface or compress the insulation beneath without leaving a visible tear. We look for bruising, cracked membrane at impact points, and areas where the protective granule layer has been stripped. Left unaddressed, those spots become entry points for the next winter’s rain.
Shingle and Tile Hail Damage
On asphalt shingles, hail leaves circular impact marks where granules are knocked off, exposing the mat underneath. On tile, hail can crack or chip the surface glaze. We document the size, spacing, and direction of impacts, because that’s what distinguishes a legitimate hail claim from normal wear.
Trusted Brands We Service in Sunnyvale
Brennan Roofing installs and services materials from GAF, CertainTeed, and Owens Corning, among other manufacturer lines. That means when a Sunnyvale homeowner has a warranty question on a GAF membrane or an Owens Corning shingle roof, we can address it directly, not hand it off to a faceless warranty department. We keep local stock of the common replacement components for the flat-roof systems we see most in Sunnyvale, including TPO seam kits, modified bitumen flashing, and roof cement for small repairs, so a minor fix doesn’t wait on a shipment.
Common Roof Inspection Problems We See in Sunnyvale Homes
- Ponding on flat and low-slope Eichler roofs. During November through March, water collects in low spots where the foam or tar-and-gravel surface has sagged. A visual-only inspection can miss the saturated underlayment beneath a still-intact top layer.
- Radiant-heating pipe punctures in Cherryhill and Fairbrae. The original Eichler design embeds copper pipes in the ceiling. A fastener driven into the wrong spot during a prior re-roof can puncture a pipe, and the leak may not show until the heating system pressurizes.
- Tree debris and overhanging canopy damage. Sunnyvale’s tree preservation ordinance protects a dense urban forest, which means valley debris, moss, and blocked drainage around penetrations are common. Some homes need a permit just to trim branches before an inspection can proceed safely.
- Failed plumbing vent penetrations. On older flat roofs, the sealant around vent pipes dries out and cracks. The leak travels sideways along the deck before it shows up as a ceiling stain, so the visible damage is often nowhere near the actual entry point.
Pricing for Roof Inspection in Sunnyvale, CA
A standard roof inspection in Sunnyvale runs $180 – $340. That includes the full walk, moisture and penetration checks, and a written report with photos. If we’re inspecting an Eichler flat roof with radiant-heating zones, expect the higher end of that range because mapping the no-penetration areas takes additional time on-site. If you need a hail-specific inspection for an insurance claim, the cost is the same, and we’ll flag it before you commit. Nobody works until you have the written price. Call (361) 320-9467 for a free estimate and we’ll schedule your inspection directly.

FAQs About Roof Inspection in Sunnyvale
A flat or low-slope roof inspection in Sunnyvale takes longer because the failure points are hidden in layers, not visible from a ladder. On an Eichler in Cherryhill or Fairbrae, we have to map radiant-heating pipe zones before we step near the roof deck, check ponding spots for saturated underlayment, and evaluate membrane seams that don’t fail until the November rains start. Add in tree-ordinance access limitations, and a thorough flat-roof inspection is a two-hour job, not a twenty-minute walk-around. If your home is a mid-century flat or low-slope build, plan for the longer visit. Call (361) 320-9467 and we’ll tell you exactly what your roof needs.
Yes. Sunnyvale’s tree preservation ordinance protects large canopy trees, including many that overhang roofs in neighborhoods like Cherryhill, Ortega, and Serra. If branches are touching the roof surface or blocking access to a valley or penetration, we may need the city’s authorization to trim before we can inspect that area properly. Debris from those same trees is also a common cause of the drainage blockages we find on Sunnyvale roofs. We handle the permit navigation and coordinate access so the inspection doesn’t stall. Call (361) 320-9467 if you think tree coverage is affecting your roof, and we’ll walk through it with you.
We look for the things unique to Eichler-built Sunnyvale homes: radiant-heating pipes embedded in the ceiling deck, original foam or tar-and-gravel roofs that have been re-coated over failed underlayment, and plumbing vent penetrations sealed over without proper decking repair. A generic inspector walking an Eichler roof with a shingle-roof checklist misses all of that. We were called to a 1958 Eichler in Fairbrae where the original foam roof had gone chalky and was ponding after the first atmospheric river of the season. While inspecting we found the tar-and-gravel underlayer had been re-coated twice without addressing the saturated underlayment, and our tech traced a slow leak back to a plumbing vent penetration that had been sealed over, right next to a radiant-heating pipe zone. We mapped the no-penetration areas, pitched a TPO membrane system over a new cover board, and wrote the decking repair as a priced allowance before any material was ordered. That’s the inspection depth a mid-century Sunnyvale roof requires.
Every surprise gets priced in writing before any repair work begins. If we find decking rot, a punctured radiant-heating pipe, or failed underlayment beneath a still-intact top layer, we document it, photograph it, and put a written price in your hand for what the fix will cost. You approve it or you don’t. There’s no door-knocking upcharge, no change order at the end of the job. That’s The Garrison Code: the number on the paper is the number you pay. Call (361) 320-9467 for an inspection, and you’ll see what we found in writing before you commit to anything.
Yes, and the difference matters for insurance claims in Sunnyvale. On architectural shingles, hail damage is visible as circular impact marks where granules are knocked off the mat. On a flat membrane, hail can bruise or fracture the surface without leaving an obvious tear, and the real damage may be compressed insulation underneath. We document impact direction, spacing, and depth of damage differently for each roof type, because adjusters need that specific evidence to approve a claim. So if your Sunnyvale flat roof took hail and a shingle-roof inspector found nothing, get a second look from someone who knows Low-slope systems. Call (361) 320-9467 and we’ll handle the report for your claim.
