Roofing Quote Checklist: What to Check Before You Sign

Why a roofing checklist matters

A roofing project is one of the largest discretionary expenses a California homeowner takes on, and most homeowners receive their roofing quotes the same way — one PDF or one printed sheet at a time, with no easy way to know whether a $14,000 quote and a $22,000 quote describe the same job, a different scope, or just different shingle grades. A checklist closes that gap. Instead of comparing dollar totals and trying to reason backward, you walk down every category that affects price, look at what each quote does or doesn't say, and put them on equal footing. The contractor whose quote covers all ten items below is not necessarily more expensive — they're more transparent. The contractor whose quote leaves five categories blank is not necessarily cheaper — they're shifting the decision (or the cost) onto you, later. This is the same checklist HomeGoSmart's quote clarity score uses, written out so you understand why each item matters.

1. Material brand, grade, and color

A vague materials line — 'asphalt shingles' or 'quality roofing material' — is the most common single omission on a roofing quote. There are real differences between brands and grades that change both lifespan and warranty. The three most common shingle brands installed in California are CertainTeed, GAF, and Owens Corning, and each makes shingles at multiple tiers: three-tab (the lowest grade, generally 20–25 year warranty), architectural or dimensional (mid-tier, 30 year warranty, the default today), and premium designer lines (40–50 year warranty, higher wind ratings, thicker profile). A quote that says 'architectural shingles' without specifying the product line — Landmark, Timberline HDZ, TruDefinition Duration — gives the contractor flexibility to swap in a cheaper line after you sign. Ask for the brand, exact product line, color, and weight per square (a 'square' is 100 sq ft of roof coverage). For a 25-square roof, the difference between a builder-grade three-tab and a premium architectural shingle is usually $2,000–$4,000 in materials alone.

2. Tear-off and disposal

Tear-off means removing the existing roof down to the deck before installing the new one. The alternative — an overlay — installs new shingles on top of the existing layer. California code allows up to two layers of asphalt shingles on most homes, so a single-layer roof can technically be overlaid, but tear-off is almost always the better long-term choice. It lets the contractor inspect the deck for rot, replace damaged sheathing, install the underlayment correctly, and address ventilation issues that would be invisible under an overlay. A complete quote spells out whether the work is a tear-off or an overlay, whether disposal and dump fees are included, and what happens if rotten deck is discovered (usually a per-sheet change-order rate of $80–$120 per sheet of replacement plywood). Disposal matters: California tipping fees for asphalt shingle waste run $50–$120 per ton, and a typical re-roof generates two to four tons. A quote silent on disposal is a quote where that cost has either been baked in or will be added later — find out which.

3. Underlayment and ice/water shield

The underlayment is what sits between the deck and the shingles, providing a secondary water barrier. The two main types are traditional asphalt-saturated felt (15# or 30#, sold by weight) and synthetic underlayment (woven polypropylene, sold by brand — Titanium UDL, RhinoRoof, Tri-Flex). Synthetic costs more but lasts longer, walks better during install, and resists tearing; most quality re-roofs use synthetic today. Ice and water shield is a self-adhering membrane that goes in vulnerable areas: valleys, eaves, around penetrations like skylights and chimneys, and sometimes the full lower edge in colder climate zones. California Residential Code R905 governs the minimum requirements. A quote should specify the underlayment brand and weight, where ice/water shield is applied, and whether it follows manufacturer warranty requirements — many premium shingle warranties are voided if non-approved underlayment is used.

4. Flashing, ventilation, and edge details

Flashing is the thin metal that seals roof transitions: where the roof meets a wall, a chimney, a skylight, or a plumbing vent. Most roof leaks don't come from the shingles themselves — they come from failed flashing. A complete quote treats flashing as its own line item and answers two questions: which flashing pieces will be replaced versus reused, and what material (galvanized steel, aluminum, copper). Chimney flashing should almost always be replaced during a re-roof; reusing it is a common corner-cut. Step flashing — the L-shaped pieces tucked under each shingle course along a wall — should never be reused. Ventilation deserves the same attention: ridge vents at the peak, soffit vents at the eaves, and balanced intake/exhaust ratios. Most California roof failures from heat-related shingle aging trace back to under-ventilated attics — a $400 upgrade at re-roof time saves a $20,000 early replacement later. Edge details matter too: drip edge along eaves and rakes is required by most codes and most manufacturer warranties, so the quote should state it explicitly.

5. Permit handling and California Title 24

A roof replacement in California almost always requires a permit. The quote should answer three questions: who pulls the permit (you or the contractor — almost always the contractor), whether the permit fee is included in the price, and what inspections the project will go through. Permit fees in California range from $150 to $800 depending on the city and the project value. Beyond the basic permit, Title 24 of the California Building Code adds energy-efficiency requirements: roofs in climate zones 10 through 15 (most of inland and southern California) must use 'cool roof' rated materials — light-colored shingles with high solar reflectance — for most re-roofs over a certain size threshold. A quote that doesn't mention permits at all is a quote where the contractor either plans to skip them (illegal, voids warranties, creates resale problems) or hasn't included the cost. Either way, you want it explicit.

6. Cleanup, magnetic sweep, and property protection

A re-roof is a destructive process. Old shingles, nails, and underlayment scatter across the yard, driveway, gutters, and landscape beds. The quote should describe how the contractor protects your property and how cleanup happens. Look for landscape tarping along the perimeter of the house, plywood protection over HVAC condensers and pool equipment, a dumpster or roll-off container on site, daily debris haul-off or end-of-day site cleanup, and — most importantly — a magnetic nail sweep over the entire perimeter at the end of the job. A handful of nails left in a lawn is the kind of mistake you only find when a kid steps on one or a tire goes flat. Magnetic sweeps cost the contractor almost nothing and reveal whether they treat cleanup as a real line item or an afterthought.

7. Warranty — manufacturer + workmanship

There are two warranties on every roof, and you need both. The manufacturer warranty covers material defects from the shingle maker — typical durations are 25 years, 30 years, 40 years, or 'lifetime,' though 'lifetime' often becomes a prorated dollar amount after the first 10–15 years. Manufacturer warranties only protect against material defects, not installation errors, and they can be voided by using non-approved underlayment, missing ventilation requirements, or improper nailing. The workmanship warranty covers installation errors and is provided by the contractor, not the manufacturer. Industry norms are 2 to 10 years; anything under 5 years on a re-roof is below market. Ask whether the workmanship warranty is transferable on resale — a transferable warranty adds real value to the home, and contractors who refuse to make theirs transferable usually do so because they don't plan to honor it for long.

8. Payment schedule

California Business and Professions Code §7159.5 caps the down payment on home improvement contracts at 10% of the contract price or $1,000, whichever is less. This is the law, not a negotiation. Any roofing contractor asking for more upfront is operating outside California law, regardless of the reason given. After the deposit, a typical schedule is: a progress payment when materials arrive on site (commonly 30–40%), another progress payment at substantial completion (another 30–40%), and final payment after the city inspection signs off and lien releases are provided. Lien releases matter — a 'conditional lien release' from the contractor and from each material supplier protects you from a supplier filing a mechanics lien on your home if the contractor doesn't pay them. Reputable contractors hand these over without being asked; less reputable ones get defensive when you bring it up.

9. Start and completion timeline

A complete quote includes both a project-start window and a project-completion window, plus how weather delays and material backorders are handled. A 'start within 2–4 weeks of permit issuance' and 'completion within 5 business days of start, weather permitting' is a normal pattern for a single-family re-roof. The weather clause matters in California winter and rainy season — what counts as a weather delay, who decides, and how much advance notice the contractor gives. Material backorders are more common than they used to be; the quote should specify what happens if the chosen shingle is unavailable (substitution should require written homeowner approval) and whether delays trigger any contractor penalty. A quote with no dates at all is a quote that lets the contractor slot you in whenever convenient — which can mean weeks or months.
