Tamko Roof Inspection in San Jose: What to Know First
We provide independent Tamko roof inspection in San Jose, typically completing the walk and written findings within two hours of arrival. A standard inspection runs $195 to $345 depending on roof size and access, and the report is yours to keep whether you hire us for repairs or not. We are an independent Tamko service provider, not a manufacturer affiliate, so the findings are straight facts, not a sales script.
If you own a Tamko roof in San Jose and you’re seeing granules in the gutter or a stain on the ceiling, this page tells you what we look at, what it costs, and what happens after. Call (669) 238-2101 and tell me what you’re seeing and I’ll tell you what it actually means.
Key Takeaways:
- Independent Tamko roof inspections in San Jose run $195 to $345, with the report in writing
- Tamko shingle failures follow patterns we can spot before they leak
- Every inspection ends with a written price for any needed work, before anything starts
- All repairs carry the 365-Day Done Right Promise in writing
How Tamko Products Fail – and How We Fix Them
Tamko builds a solid shingle, but every manufacturer has patterns. After years of inspecting Tamko roofs across San Jose, from Willow Glen ranchers to Rose Garden two-stories, here’s what we actually find:
- Heritage series granule loss at the south-facing slopes. San Jose sun is unkind to any asphalt shingle, but Heritage shingles on full-sun exposures tend to shed granules faster than shaded slopes. It looks like a light dusting of sand in the gutter. We check granule depth with a gauge and map the affected slopes, because once the asphalt is exposed, the clock is running. Fix is usually slope replacement before decking gets wet.
- Elite Glass-Seal sealant strip failures on steep pitches. Tamko’s sealant strips do their job until a steep roof gets years of thermal cycling and the bond lets go at the corners. We find lifted shingle tabs on pitches above 7/12 that look fine from the ground. These get hand-sealed with a Tamko-compatible adhesive, not caulk from a big box store.
- MetalWorks stone-coated steel fastener backout. On Tamko MetalWorks roofs in San Jose’s wind corridors, we occasionally find fasteners that have backed out a few turns over a decade of expansion and contraction. These aren’t leaks yet, but they will be. We torque-check a sample across every plane and replace any fastener that’s lost its bite.
- Flashing integration issues at dormers and sidewalls. This isn’t a Tamko defect, it’s an installation one. But Tamko’s dimensional shingles are thicker than three-tab, and we see original flashings that weren’t stepped correctly for that thickness, especially around chimneys near The Alameda’s older homes. Water gets behind the flashing, not through the shingle. We pull it, replace it, and step it correct for the shingle profile.
- Underlayment fatigue under lightweight Tamko lines. Older Tamko fiberglass shingle installs often sit on felt underlayment that’s breaking down even where the shingles still look serviceable. In crawl-space inspections we check the attic side for black streaks on the decking, which tells us the shingle is still shedding water but the felt is done. Fix is a re-deck and new synthetic underlayment when we re-roof.

Our Tamko Roof Inspection Process
Every Tamko inspection in San Jose follows the same path, so you know what’s happening from the first call to the final handshake:
- 1
You call (669) 238-2101. A live person answers and books a window that works for you. No call center, no menu tree.
- 2
We walk the roof and the attic. The technician checks shingle condition, granule depth, sealant bonds, flashing integration, underlayment condition, and ventilation. Photos of everything we flag.
- 3
We check the Tamko-specific failure points. South-slope granule loss, sealant strip bonds on steep pitches, fastener tension on metal lines, and flashing steps at dormers and chimneys.
- 4
We write the findings in plain English. Every issue gets a photo, a severity rating, and a real fix recommendation. No jargon, no vague “recommend further evaluation” filler.
- 5
We price the work in writing. If repairs are needed, the price goes on paper before any work starts. That number does not move at the door.
- 6
You decide. We’re not going to pressure you. If you want the work done, we schedule it. If you don’t, you keep the report.
Every inspection and every repair is backed by the 365-Day Done Right Promise. If the repair fails within a year, we come back at no charge. In writing.

FAQs
No. An independent inspection by us does not affect your Tamko warranty in any way. We don’t alter or modify anything during an inspection. If we recommend repairs, we’ll tell you which ones fall under Tamko coverage and which are normal wear. Call (669) 238-2101 and we’ll walk you through it.
We can typically get a technician to your San Jose home within a few days of your call, and the inspection itself takes about two hours. You’ll have the written report in hand before we leave the driveway, not three days later by email. Call (669) 238-2101 to pick a window.
We do both. Most Tamko repairs in San Jose run $250 to $800 for flashing, sealant, and small shingle work. If the damage is extensive, we’ll tell you straight whether repair makes sense or whether a re-roof is the smarter money. The written quote includes both options when it’s a judgment call.
No. The price goes on paper before any work starts, and it doesn’t move at the door. If we open up the roof and find hidden decking damage, we stop, show you photos, and give you a written change order before anything else happens. You approve it or you don’t. That’s The Garrison Code.
Yes. We inspect and service roofs built with GAF, Owens Corning, CertainTeed, IKO, Atlas, and Boral materials. Knowing multiple manufacturers’ failure patterns makes our Tamko inspections sharper, because we know what’s unique to Tamko versus what’s a general roofing issue. Call (669) 238-2101 for any brand.
