Why a roofing job can be a lead job
Lead-based paint was banned for residential use in the United States in 1978, and many New England homes are older than that. On those houses the roofing itself is rarely painted — the wood around it often is. A re-roof routinely disturbs:
- Fascia and rake boards — painted wood that is often removed or replaced at the roof edge.
- Soffits and eave trim — disturbed when drip edge, gutters or ventilation are changed.
- Dormer siding and trim — cut back where new roofing meets the dormer walls.
- Painted trim at chimneys and sidewalls — disturbed when step and counter flashing is replaced.
EPA's Renovation, Repair and Painting (RRP) Rule applies when paid work disturbs more than 20 square feet of exterior painted surface on a home built before 1978, or on a child-occupied facility such as a home daycare — unless a certified inspector or risk assessor has found the affected surfaces free of lead-based paint.
What lead-safe work looks like on your roof
These are the RRP Rule's requirements for exterior work, which apply on every covered job:
Before work starts
You receive EPA's Renovate Right pamphlet no more than 60 days before work begins, and warning signs go up around the work area (40 CFR 745.84 and 745.85).
A certified renovator on every job
The rule requires a certified renovator to be assigned to each renovation the firm performs, and everyone disturbing paint to be a certified renovator or trained by one (40 CFR 745.89(d)).
Containment outside the house
Doors and windows within 20 feet of the work are closed, and the ground is covered with disposable plastic sheeting extending 10 feet beyond the work area — further if debris could travel farther (40 CFR 745.85(a)(2)(ii)).
Prohibited practices
No open-flame burning or torching of painted surfaces; no high-speed sanding or grinding unless the tool is shrouded and connected to a HEPA vacuum; heat guns only below 1,100 °F (40 CFR 745.85(a)(3)).
Cleanup and verification
Paint chips and debris are collected and contained, and a certified renovator visually inspects the work area and the ground below it before the warning signs come down (40 CFR 745.85(b)).
Records
The firm keeps its compliance records for three years after the job is complete (40 CFR 745.86).
Where our EPA certificate applies in New England
EPA firm certification is valid only where EPA runs the RRP program. Three New England states run their own EPA-authorized programs instead, and those states license lead-safe renovation work themselves.
Lead-safe roofing questions, answered
Does the EPA lead rule apply to a roof replacement?
It can. EPA's Renovation, Repair and Painting (RRP) Rule covers paid work that disturbs painted surfaces in homes built before 1978 and in child-occupied facilities. Exterior work that disturbs 20 square feet or less of painted surface counts as minor repair and is exempt. A re-roof that replaces fascia, rake trim, soffits or dormer siding can exceed that threshold.
How do I know whether my home is covered?
The rule applies to "target housing": homes built before 1978, the year lead-based paint was banned for residential use. Narrow exceptions exist — housing for the elderly or people with disabilities, and zero-bedroom units, unless a child under six lives there — and work is exempt where a certified inspector or risk assessor has found the affected components free of lead-based paint.
Is your EPA certificate valid in Massachusetts, Rhode Island or Vermont?
No. Massachusetts, Rhode Island and Vermont administer their own EPA-authorized programs, and EPA firm certification does not apply in those states. In Vermont, we hold Vermont Department of Health Lead RRP Firm RRPM-Firm-100386. EPA certificate NAT-34864-4 covers our work in Connecticut, Maine and New Hampshire.
How can I verify your certification?
Open the certificate PDF on this page, search EPA's public locator of certified renovation firms, or call the National Lead Information Center at 1-800-424-LEAD and quote certificate number NAT-34864-4. The certificate was issued to Interlock Metal Roofing (New England) Inc., formerly known as Interlock Industries, Inc.
Does the EPA endorse your company or the Interlock® roofing system?
No. EPA certification means the firm meets the RRP Rule's requirements for lead-safe renovation work. It is not an endorsement of any company, product or service.
When does the certification expire?
Certificate NAT-34864-4 expires June 23, 2031. EPA firm certification runs for up to five years, after which the firm must re-certify.
