Burbank, Illinois?

Burbank roof replacement permits — the key details

Burbank enforces the three-layer prohibition strictly per IRC R907.4. If a field inspection reveals three or more layers of roofing material on your home, the contractor must tear off all existing material down to the deck before installing new shingles or other covering. This is not negotiable — overlays are forbidden in Burbank once the three-layer threshold is met. The city's Building Department typically discovers this during the rough-in inspection, which happens after old material is removed and the deck is exposed. If your contractor did not pull a permit before starting the tear-off and the inspector finds the third layer, you'll face a stop-work order, potential fines, and mandatory removal of the new roofing to expose the deck for inspection. The permit application itself asks how many existing layers are present; answer honestly, as the inspector will verify this claim before signing off on the deck nailing inspection.

Like-for-like replacements — shingle-to-shingle with the same pitch and assembly — are often processed as over-the-counter permits in Burbank, meaning you can get approval and start work the same day you file. However, any change in material (asphalt shingles to metal panels, architectural to slate, or shingles to tile) triggers a full plan review because the structural load, attachment method, and deck requirements differ. Metal roofs, for instance, require a different fastening pattern and may need additional deck reinforcement depending on the pitch and local wind load (Burbank uses ASCE 7 standard wind speeds, roughly 90 mph for 3-second gust). Tile and slate trigger a structural engineer review because the deck must support live loads of 20 pounds per square foot or higher. Expect 7–14 days for plan review if the material changes. Underlayment specification is critical: asphalt shingles require synthetic or felt per ASTM D226, and Burbank inspectors will ask for proof of product type and manufacturer certification at the rough-in stage.

Ice-and-water-shield installation in Burbank must extend a minimum of 24 inches up the roof plane from the eaves on all replacements, per local amendment to IRC R905.1.1 (this is a cold-climate requirement driven by the 42-inch frost depth and freeze-thaw cycling). The city treats this as a key point in the rough-in inspection — the inspector will walk the roof and look for the shield installation along the drip edge and at any valleys or hips. If you're reroofing a roof with a valley that feeds water toward a lower slope or a skylight, the shield extends beyond the minimum. This is not a cost-cutting area; it is one of the most common rejection reasons on Burbank roofing inspections. Your contractor should specify ice-and-water-shield product, width, and location on the permit drawings or in a written specification submitted with the application. Do not assume it's included in the quote without asking the contractor explicitly.

Deck nailing (or fastening) inspection is mandatory on all tear-offs in Burbank. When the old roofing is removed, the inspector will examine the existing deck for rot, structural damage, and nail spacing. IRC R905.2.8.5 requires fasteners to be spaced no more than 6 inches apart in the field of the roof and 4 inches at the edges (this prevents wind uplift and blow-off). If the existing deck is found to be damaged — soft spots, gaps, or water-damaged plywood — the contractor must sister new members or replace the affected section before new roofing goes down. This can add 2–5 days to the project timeline and $1,000–$3,000 in material and labor. Have your contractor inspect the roof cavity from the attic (if accessible) before the permit application to identify potential deck issues; it's cheaper to budget for this upfront than to discover it during inspection.

Permit fees in Burbank are typically calculated on a per-square basis (one square = 100 square feet of roof area). A standard single-story home (1,500–2,000 sq. ft.) with a roof area of roughly 1,500–2,000 sq. ft. (depending on pitch and complexity) usually falls into the $150–$300 permit range. If the roof includes structural repairs or a material change that requires plan review, add $50–$150 for additional review. The fee is due at the time of application. Payment is accepted online through Burbank's permit portal (accessible via the city website) or in person at City Hall during business hours. Once the permit is issued, your contractor has 180 days to complete the work before the permit expires; if work extends beyond that, a renewal or extension can be filed (typically $25–$50 additional fee). Final inspection must be scheduled within 10 days of completion; the inspector will verify material, fastening pattern, underlayment, and flashing before sign-off.

Three Burbank roof replacement scenarios

Why Burbank enforces the three-layer rule so strictly

The three-layer prohibition in IRC R907.4 exists because multiple layers of roofing material trap moisture between the shingles and the deck, accelerating rot and structural decay in freeze-thaw climates like Burbank's. With a 42-inch frost depth and average winter temperatures dipping to 10–15 degrees Fahrenheit, ice dams form along the eaves, forcing water up under the shingles and into the gaps between layers. Over 10–15 years, this moisture softens the deck, rots the rafters, and can lead to interior mold and structural failure. Burbank Building Department inspectors are trained to spot telltale signs: soft spots when walking the rough-in, visible delamination of the shingle tabs at the edges, and discolored or spongy plywood when exposed. The city has invested in this enforcement because unpermitted or out-of-code reroofing work shows up in insurance claims (water damage, mold remediation) and, in extreme cases, structural failure lawsuits. By requiring the tear-off and permitting it, the city shifts liability to the contractor and homeowner and ensures the deck is inspected before new material goes down.

Many homeowners in Burbank assume they can save money by overlaying the existing roof on top of two layers already present, but this violates both IRC R907.4 and Burbank's local enforcement. Contractors who offer overlays on three-layer roofs are either uninformed or deliberately skirting code. Burbank's plan reviewers routinely ask for the existing layer count, and field inspectors check the tear-off to confirm the count matches the application. If the inspector arrives for rough-in and discovers three layers (when the permit claimed two), the contractor faces a stop-work order, mandatory tear-off to expose all layers, and possible fines. This has happened enough times in Burbank that contractors now recommend a pre-permit attic inspection (from inside, without disturbing the roof) to count existing layers before the application is filed. The cost is $150–$300 but saves thousands in rework.

Burbank also enforces the three-layer rule to keep insurance claims low. The city's Building Department shares data with the local insurance agents' association, and carriers pricing homeowners policies in Burbank factor in the city's permitting rigor. Homes with permitted roofing work and final inspection stamps are cheaper to insure than those without; conversely, homes discovered to have unpermitted roofing work face rate increases or cancellation when the insurer finds out. This creates a second incentive for homeowners to permit: your insurance company will ask for proof of permit and final inspection before paying a roof-related claim, especially if the damage occurred within 5 years of the roofing work. Skipping the permit may seem faster and cheaper upfront, but it costs money at claim time.

Ice-and-water-shield and Burbank's cold-climate amendments

Burbank adopted a 24-inch minimum ice-and-water-shield requirement as a local amendment to IRC R905.1.1, driven by the city's history of ice dam damage and the 42-inch frost depth. Unlike southern climates where ice dams are rare, Burbank sees ice buildup along the eaves nearly every winter when warm attic air meets cold outside air. If water seeps under the shingles and into that gap, it refreezes, forming a dam that backs water up under the shingles and into the house. Ice-and-water-shield is a self-adhering underlayment (typically bituthene or polymer-based) that bonds to the deck and does not allow water to pass through even under pressure. The 24-inch measurement is from the drip edge of the eaves up the roof plane; on a 6:12 pitch, that translates to roughly 288 inches horizontally across a typical roof, or a 2-foot-wide strip running the entire eave length.

Burbank inspectors check ice-and-water-shield installation at the rough-in stage by looking for the adhesive line along the deck and asking the contractor to pull back a corner to confirm the seal. If the shield is installed but only extends 12 inches (a common shortcut), the inspector will flag it as a deficiency and require the contractor to install the additional 12 inches before the roof covering goes down. This is one of the most frequently cited correction items on Burbank roofing inspections, partly because contractors working in milder climates (southern Illinois, Indiana) often use their home-state standards rather than learning Burbank's local rule. Specify the ice-and-water-shield requirement in writing in your permit application or in the contractor's scope of work to avoid surprises.

The cost of ice-and-water-shield is roughly $1–$2 per square foot, so for a 1,800 sq. ft. roof with 24-inch coverage at the eaves (roughly 300 sq. ft. of material), expect $300–$600 in material alone. This is rarely negotiable in Burbank permits — it's a code requirement, not an upgrade. Your contractor should include this in the estimate without prompting. If the estimate does not break out ice-and-water-shield separately, ask for it explicitly. Some contractors bundle it into 'underlayment' and mark it up, while others list it as a line item. Either way, confirm the quantity and product type before signing a contract. Cheap ice-and-water-shield products (thin or low-tack) often fail to bond properly to the deck in cold weather, so Burbank inspectors sometimes ask for product certification (a data sheet or mill certificate) at rough-in to confirm the product meets ASTM D1970 or equivalent.
