When coastal mornings give way to afternoon heat, Bay Area attics routinely climb past 120 °F. That trapped heat radiates downward, forcing HVAC systems to work overtime and shortening the life of roofing materials. A properly sized attic fan exhausts super-heated air, protecting both comfort and construction investment. CountBricks delivers end-to-end service—from AI-driven estimates to final inspection—so homeowners and contractors know exactly what an attic fan project will cost, how long it will take, and which materials perform best in micro-climates from San Jose to Marin.
Manual takeoffs and handwritten invoices still dominate small residential projects. Unfortunately, those methods
• Inflate labor allowances because square footage is measured twice “to be safe”
• Miss real-time supply chain price swings, leading to margin loss or awkward change orders
• Delay project start dates while the office “gets the paperwork together”
CountBricks replaces guesswork with instant voice-to-estimate technology. Speak measurements into your phone while you’re in the attic, and our AI converts the conversation into a detailed line-item quote—materials, tasks, labor hours, taxes and Bay Area permit fees included.
Describe rafter spans, roof pitch, and electrical access points out loud. CountBricks captures the audio, identifies tasks such as “cut roof vent,” “install 14-inch solar fan,” and “tie into dedicated circuit,” then assigns current Bay Area labor rates. Clients receive a polished proposal before you leave the driveway.
Our platform syncs with regional suppliers every morning. When galvanized flashing or 6-gauge THHN wire jumps in price, the change is reflected instantly—no more budget-busting surprises halfway through the job.
Uploading PDF plans? CountBricks detects roof area, calculates required CFM, and recommends fan sizes backed by manufacturer specs. You approve or adjust within seconds.
With a single click, transform the estimate into a branded PDF that includes warranty language, payment terms, and digital signature fields. Homeowners can approve from any device.
The International Residential Code recommends 1 CFM of ventilation for every 1 sq ft of attic floor area, adjusted for roof color and Bay Area micro-climate. CountBricks calculates this automatically, but here are the fundamentals:
• 1,000 sq ft attic with light shingles: 1,000 CFM fan
• 1,000 sq ft attic with dark shingles: 1,200 CFM fan
• 2,000 sq ft attic, mixed shade: 2,200–2,400 CFM fan
Solar-powered units lower operating costs, yet wired models offer higher CFM and smart-thermostat integration. CountBricks catalogs both and presents side-by-side ROI comparisons in your estimate.
City and county jurisdictions each enforce subtle differences in mechanical ventilation codes. For instance, San Jose requires separate electrical permits when tying into existing circuits, while Oakland allows same-day over-the-counter approval for solar-only fans. CountBricks’ AI checks the project ZIP code, auto-loads the correct permit fees, and flags additional requirements such as fire-rated collars in Wildland-Urban Interface zones.

PG&E estimates every 10 °F reduction in attic temperature yields a 3–5 % reduction in cooling costs. Bay Area households often recover installation costs within three summers, and solar units shorten payback to two. CountBricks includes customizable ROI charts in every proposal, helping homeowners make a confident, data-backed decision.

An attic fan may be a small job, but customer experience should feel premium. CountBricks transforms quick installations into showcase moments of professionalism—earning repeat business and referrals across the Bay Area.
A San Mateo homeowner suffered summer indoor temps of 82 °F even with a new heat pump. Their 1970s split-level held 1,400 sq ft of attic space under dark composite shingles—ideal conditions for trapped heat. Local contractors warned of multi-day disruptions, but with CountBricks the project finished in six hours.
• Voice capture on initial walkthrough documented joist spacing, electrical panel location, and roof slope in under three minutes.
• CountBricks AI recommended a 1,600 CFM smart wired fan plus smart switch integration, forecasting a 4-year ROI.
• Permit fees for San Mateo County auto-populated at $132 and were included in the first client-ready proposal.
• Material order synced to a preferred supplier; delivery window was visible inside the CountBricks dashboard, removing guesswork for both crew and client.
• Attic peak temperature dropped from 126 °F to 98 °F on the first 90 °F day
• HVAC runtime fell by 18 %, verified through the homeowner’s smart thermostat reports
• Total invoice landed within 2 % of the initial AI estimate—no change orders, no surprises
• Position the fan on the leeward roof face to harness prevailing coastal winds for passive boost.
• Use a combination of ridge vents and gable vents to ensure balanced intake when the fan engages.
• Offer homeowners a monitoring app; real-time data reinforces the value of your work and secures positive reviews.
Whether you retrofit a single-story bungalow or specify ventilation for a custom hillside build, CountBricks eliminates the paperwork drag so you can focus on quality installation.
