Need a roof looked at in Oakland? Tell us why. Buying a house, selling one, insurance asking questions, or just want to know how many winters you have left. You’ll hear back from one vetted, licensed Oakland roofer.
Get it done in September
Oakland’s rain is not spread across the year. Roughly 23 inches falls between November and April, mostly in a handful of big Pacific storms, and the roofing trade in the East Bay flips from quiet to unreachable in the week after the first one. Every leak call in the city arrives at the same time.
So the useful inspection happens in late summer, while the roof is dry, the crews have availability, and any repair that turns up can be scheduled properly instead of squeezed between storms in December. An inspection now costs a few hundred dollars. An emergency tarp and an in-storm repair in January costs several times that and buys you a worse result.
What a real inspection covers
The field of the roof is the least interesting part. A competent inspector spends his time on the interruptions, because that is where Oakland roofs fail: the chimney flashing and whether it’s actually counter-flashed into the masonry or just smeared with mastic; the roof-to-wall junctions where a second story lands on a first-story roof, which is the number one source of a mystery ceiling stain in a Victorian; the vent boots, whose neoprene collars split from UV after about 12 years; the valleys; the skylight curbs; and the low-slope rear addition, where he’s looking for standing water, ponding rings, blisters, and open seams.
Then he goes in the attic, if there is one. The underside of the sheathing tells the truth. Old stains that are dry and crusty are historical. Dark, damp, or freshly rimmed stains are active. Mold on the north-facing sheathing usually means a ventilation problem rather than a leak, which is a different and cheaper fix.
On a pre-1940 Oakland house, he should also be telling you what the deck is. If it’s skip sheathing, that’s a $3 to $6 per square foot re-decking line item on any future replacement, and you want that in your head now, not on the day the roof comes off.
Buying a house in Oakland? The general home inspector did not inspect your roof
This is worth being blunt about. A general home inspector will look at the roof from the ground, or from a ladder at the eave, or occasionally walk it if the pitch is gentle. He is a generalist, he has 15 systems to cover in three hours, and his report will say something like “roof appears serviceable, recommend evaluation by a licensed roofing contractor.” That sentence is not a clean bill of health. It is a disclaimer.
On a $900,000 Oakland Craftsman where a reroof with re-decking is $25,000, spending $300 to $600 on a roofer’s inspection during your contingency period is the cheapest insurance available to you. And in the hills it’s not optional. A house in Montclair or Piedmont Pines with a roof that predates the current Chapter 7A requirements may need a full Class A assembly and ember-resistant vent retrofit at replacement, which is a materially different number than a flats reroof, and it is not a thing you want to discover after close.
Insurance inspections
California’s homeowners insurance market has been brutal in fire-exposed areas, and carriers have been non-renewing or demanding documentation on older roofs, particularly in the Oakland hills. A roof certification from a licensed roofer, stating the material, the estimated remaining life, and that the roof is in serviceable condition, is often what a carrier wants. Some will also want confirmation of ember-resistant venting.
If your carrier has sent you a letter, read it carefully and tell us exactly what it asks for. The certification a carrier requires and a general inspection report are not the same document.
What it costs
A standard residential roof inspection in Oakland runs about $200 to $500. A roof certification for insurance or a real estate transaction is typically $300 to $600, because there’s a signed document and liability attached to it. Some roofers waive or credit the fee if you go on to have them do the work, which is fair, but be aware of the incentive it creates: an inspector who only gets paid if he finds work has a reason to find work. A paid, independent inspection from someone who is willing to tell you your roof is fine is worth what it costs.
Drone and infrared inspections get marketed hard. On a residential Oakland roof, a drone is a convenience for photos on a roof too steep or brittle to walk. It is not a substitute for someone getting up there and putting hands on the flashing. On a commercial low-slope roof, infrared is genuinely valuable, because it finds the wet insulation you cannot see.
Questions
How often should I have my roof inspected?
Every two or three years on a roof under 15 years old. Annually, in late summer, once it’s past 15. And after any windstorm that takes branches down in your neighborhood.
My roof is 22 years old but it isn’t leaking. Do I need to do anything?
Get it looked at, and start budgeting. Composition shingle roofs in this climate go 20 to 30 years depending on the product and the exposure, and the ones that make 30 are the ones that got their flashings maintained. A roof that isn’t leaking today can be one storm from leaking. The tells are granules in the gutters, curled or cupped shingle corners, and bare patches on the south and west slopes where the UV hits hardest.
Will an inspector walk my roof, or just look from a ladder?
Depends on the roof. A 10:12 Victorian hip roof with brittle 25-year-old shingles is genuinely dangerous, and walking it will damage it. In that case a good roofer works from the ladder at the eaves, uses a drone or a pole camera for the field, and gets into the attic. What matters is that he actually looked at the flashings, not the method he used to see them.
The inspector says I need a new roof. Do I get a second opinion?
If the person telling you is the person who wants to sell it to you, yes. Always. Ask him to show you photos of what he found. A roofer who can point at a specific failed detail and explain it is telling you something real. One who gestures at the age of the roof and hands you a proposal is selling.
Book it
Tell us the neighborhood, roughly when the house was built, and why you need the inspection. Purchase contingency, insurance letter, or peace of mind before the rain, they’re different jobs and it helps to know which one you’re asking for.
