St. Helena is a different inspection than most towns. You’ve got 1880s Victorians with original redwood shake, 1920s bungalows with cedar shingles, and newer wine-country estates with tile or composite. And after the 2020 Glass Fire, Napa County tightened its wildfire code so far that almost every re-roof here now triggers Class A assembly requirements. That changes what an inspection has to look for. Our Roof Inspection team documents what’s failing now and what the county will require when you eventually replace it, so the quote you get reflects the real scope, not a ballpark.

Why Brennan Roofing Is St. Helena’s Preferred Roof Inspection Company

We show up when we say we will, and the price goes on paper before any work starts. That’s the Garrison Standard, and it applies the same on a 1,200-square-foot bungalow near Lyman Park as it does on a 6,000-square-foot estate off Howell Mountain Road. Travis Oakley runs our St. Helena operations, and every tech dispatched here is background-checked and in uniform. You know who is walking your roof.

St. Helena homeowners call us because inspections here are not routine. A house in town might share a property line with a 130-year-old structure. A place out in the county might have three buildings on one parcel. We have scoped enough of both to know where problems hide. Our reports include photos, specific measurements, and a written price for any repair or re-roof the inspection turns up. One visit, one document, no second-guessing.

When you call (361) 320-9467, a live person answers. Not a voicemail system. That matters when you’re standing in your kitchen looking at a water stain and trying to figure out how urgent it is. We’ll get you scheduled, and if the inspection turns up a problem, we come back to fix it under the same Garrison Standard.

Hail Damage Roof in St. Helena

Hail Damage Roof in St. Helena is less common than wind-driven ember damage, but it does happen, usually in spring when a cold front pushes through the valley. Hail here tends to bruise asphalt shingles and crack clay tile before it causes obvious leaks, which means damage can sit unnoticed for months. An inspection after a hail event documents bruising, granule loss, and impact fractures before they become full failures.

What We Check After a Hail Event

We look for circular impact marks, soft spots in asphalt that indicate a bruised mat, and cracked or spalled tile. On metal roofs, we check for dimpling that can compromise the coating. We also inspect flashing and vents, because hail rarely hits only the field of the roof.

Documenting for Your Insurance Claim

We photograph every impact area, mark it on a roof diagram, and note the age and condition of the surrounding material. That documentation goes straight into your claim file. A typical hail-damage repair in St. Helena runs $600 – $2,800 depending on how many slopes took hits. Call (361) 320-9467 to get an inspection on the books.

Roof Estimate in St. Helena

A Roof Estimate in St. Helena should start with a real inspection, not a drive-by from the street. We walk the roof, document what we see, and then write a number that covers the actual scope. Most full roof replacements here run $14,000 – $38,000 on a standard single-family home, with acreage properties and historic homes trending higher because of fire-rated assembly requirements and structural unknowns. The written estimate you get from us is the price. It does not move at the door.

What a Real Estimate Includes

Our estimates break out materials, tear-off, decking replacement, underlayment, flashing, vents, and disposal as separate line items. No lump-sum mystery. If the county requires ember-resistant vents or a non-combustible underlayment, that is in the estimate from the start, not added later as a surprise.

Scoping Before Quoting on Acreage

On larger parcels, we walk every building before we quote. A detached shop, a guest house, a barn with a failing ridge vent, each one changes the number. We also check access paths for material delivery and waste removal, because a long haul from the road to the structure adds labor hours. Grading and drainage get noted too, since water running toward a foundation shortens any roof’s service life. Call (361) 320-9467 to schedule a free estimate.

We install it to manufacturer spec and stand behind it in writing.

Common Roof Inspection Problems We See in St. Helena Homes

• Deteriorated underlayment beneath original shake. Redwood and cedar shake from the late 1800s and early 1900s often sits on felt that has turned to powder. The shake looks intact from the ground, but water is getting through. We map every bad square before quoting.
• Brittle drip edge and failing rake flashing. Decades of St. Helena’s hot, dry summers bake metal flashing until it cracks. The wind that comes through the valley in fall then works water under the edge. This is a common issue on homes off Madrona Avenue and in the older neighborhoods near downtown.
• Skipped outbuildings on acreage parcels. A shop, detached garage, or ADU has its own decking, flashing, and ridge vent condition. When an inspection only covers the main house, the quote is wrong before it’s written. We scope every structure on the parcel.
• Ember-intrusion vulnerabilities. Post-Glass Fire code now requires ember-resistant vents and non-combustible underlayment on most re-roofs in Napa County. An inspection needs to flag whether your current vents and underlayment would pass, because that determines whether a simple re-roof becomes a full fire-rated assembly upgrade.
