Are NYC DOB permits updated daily in PermitGrab?

Yes — NYC permit data is pulled daily from the NYC Open Data portal (the NYC DOB Job Application Filings dataset and HPD/DOB violation datasets). New filings appear in the feed within 24 hours.

Can I filter NYC permits to roof work only?

Yes. The NYC permit data includes permit_type, job_type, and work_type fields. Filter to job_type "A2" or work_type containing "ROOF" / "ROOFING" to focus on roof-specific filings. The query syntax is documented on the NYC permits page.

Does PermitGrab include NYC contractor licensing data?

Yes — we pull NY State Department of State licensing data for the contractors who appear in the NYC permit feed. This includes home improvement contractor (HIC) licensing for the five boroughs. About 791 NYC contractors had phone numbers in the latest pull; the actual NYC licensee universe is larger but not all licensees pull permits regularly.

What's the difference between PW1, PW1A, and PW2 permit forms?

PW1 is the initial plan-work permit application. PW1A is an amendment to a previously-issued PW1. PW2 is the work permit that follows after PW1 plan approval. Most roofing contracts are bid against the PW1 stage; the PW2 issue date marks when the project is fully approved to proceed.

Are NYC HPD violations useful for roofing leads?

Yes — HPD violations include several roof-related codes (e.g. roof leaks, hazardous roof conditions, missing roof flashing). Buildings with active HPD roof violations are required to remediate, which typically means filing a permit and bidding the work. Cross-referencing HPD violations against permit filings surfaces buildings where the work is pending but not yet bid out.

NYC Roofing Contractor Leads from Building Permit Data

Published 2026-05-02 · 6 min read · Audience: Roofing contractors in NYC

New York City files more building permits than any other US city — and a meaningful slice of them are roof work. Co-op and condo boards, brownstone owners, multifamily landlords, and commercial property managers all file with NYC DOB before any roof project starts. For roofing contractors with NYC licensing, that filing is a sales signal — competing bids are open, the project is real, and the homeowner has already committed to spending.

PermitGrab pulls NYC DOB permits and HPD violations daily across all five boroughs. Here's how roofing contractors use it.

What's in the NYC data feed

Daily NYC DOB permit feed across Manhattan, Brooklyn, Queens, Bronx, and Staten Island
5,000 NYC PLUTO property owner records with BBL (borough-block-lot) IDs and addresses
NYC HPD and DOB violations — useful for cross-referencing buildings with code-mandated roof or facade work
791 NYC contractor profiles with phone numbers in the latest pull (NYC contractor licensing data is harder to enrich than other states; this is what we have)

The four NYC roof permit signals roofing contractors should watch

1. PW1 (Plan Work) Type 2 alterations involving roofing

NYC's permit taxonomy uses PW1 forms for most permitted work. Type 2 alterations include re-roofing, roof structural changes, and roof-mounted mechanical equipment. Filter permits by job_type "A2" or "Alt 2" + work_type containing "ROOF" to surface roof-specific filings.

2. Local Law 11 / FISP (Facade Inspection Safety Program) cycle filings

NYC requires periodic facade and parapet inspections on buildings 6 stories or taller. When an FISP cycle uncovers issues, the building owner files a permit for repairs — often involving roof flashing, parapet work, and waterproofing tied into the roof system. FISP-driven work is contractor-specific (engineers and architects approved for FISP work), but the underlying contracts include roofing scopes that get bid out.

3. Local Law 97 retrofit-driven roof work

NYC's Local Law 97 (greenhouse gas emissions for buildings 25,000+ sq ft) is driving HVAC and envelope retrofits across the city's commercial and large-multifamily stock. Many LL97 retrofits involve cool-roof installations, solar-ready roof reinforcement, or full roof replacement to eliminate thermal bridges. These permits are filed as alterations and identifiable by description fields containing "energy", "retrofit", "HVAC", or "envelope".

4. Demolition + new-construction permit pairs

When a NYC lot files a demolition permit followed by a new-construction permit on the same BBL, you have a brand-new roof contract entering the bid market 12-24 months later. Track demolition + new-construction permit pairs to build a forward calendar of roofing contracts.

Borough-specific patterns for NYC roofing contractors

Manhattan. Mostly commercial roof work and high-rise residential. Filtered to commercial permits, this is a high-margin / long-cycle market — six months from permit filing to roof contract bid is typical. Few residential opportunities compared to outer boroughs.

Brooklyn and Queens. The bread and butter for NYC residential roofing — brownstones, two-families, three-families, and small multifamily. Most permits convert to bid opportunities within 30-60 days. This is where most NYC residential roofers focus.

Bronx. Heavy multifamily and HPD-rehab work. HPD violations on roof systems generate permit filings; tracking the HPD-violation-to-permit transition surfaces these opportunities.

Staten Island. The most "suburban" of the boroughs — single-family and small multifamily roof work, similar dynamics to suburban Long Island.

How NYC roofing contractors actually use the data

Daily borough scan. Filter NYC permits filed in the last 24-48 hours by borough and permit_type. Hand to a junior estimator who calls each filer (architect, engineer, or property owner of record) with a "we noticed your filing — can we put a roofing bid in?" pitch.

Co-op and condo board outreach. Multi-family permits in NYC typically have a managing agent on file. PermitGrab includes the filer's contact info where the city captures it. Managing agents control multiple properties and one good relationship feeds 5-15 buildings of work.

HPD violation cross-reference. Filter HPD violations to roof-related codes, intersect with the property_owners feed, and direct-mail building owners with active roof violations.
