Metal roofing questions, answered

Metal Roofing New York is how Long Island homeowners get the Interlock® aluminum roofing system. It supplies the roof, made by Interlock Roofing, certifies independent roofing contractors on the system and assigns one to your project. The roof carries the Guardian Lifetime Limited Material Warranty, issued by Interlock Roofing. It does not install roofs, hold a contractor license, set prices or name installers on this site.

No. The certified Interlock installer assigned to your project, an independent contractor holding a Nassau County or Suffolk County home-improvement license, measures the roof, prices the job, signs the contract with you, pulls the permit and does the work.

A certified Interlock installer for your area is assigned to your project and contacts you to arrange a visit. They look at the roof and the deck and give you a written proposal: the price, the profile and color, the deck and underlayment work and the schedule. There is no obligation.

From the installer's written proposal, after they have seen your roof. Prices are not published here, because the deck, the shape of the roof, the code that applies at your address and the profile all change the number.

Nassau and Suffolk counties, from the Queens line to Montauk. New York City's five boroughs, Westchester, the Hudson Valley and upstate are not served.

An independent roofing contractor who has completed the manufacturer's product-installation certification for the Interlock® system. The installer carries their own Nassau County or Suffolk County home-improvement license.

The installer. The proposal, the contract, the price, the permit and the workmanship terms are between you and the certified Interlock installer assigned to your project.

Nassau and Suffolk each license home-improvement contractors at the county level. Check the license number on the contract with Nassau County or Suffolk County Consumer Affairs before you sign.

The installer, under their own name. The permit, the inspections and any code questions at your address are the installer's responsibility.

The installer is assigned after you send your request. Their name, contact details and license or registration are on their proposal and contract. This site does not list installers.

Sometimes. The ICC-ES report for the system, ESR-1790, covers installation over an existing roof when the building code's conditions for a recover are met, and the old flashings must be replaced. The installer checks the deck and the existing layers and tells you in the proposal whether a tear-off is needed.

The Guardian Lifetime Limited Material Warranty is issued by Interlock Roofing, the manufacturer. It covers the aluminum material and its factory finish against manufacturing defects, subject to the exclusions in the document. The Alunar® coating is warranted for 30 years against chalking and fading beyond stated limits.

The life of the original purchaser, for as long as they remain the registered owner of the home. It is not the life of the house, and it is a limited warranty: the document sets out what is covered and what is excluded.

Yes, once. The next registered owner is covered to 50 years from the substantial completion date. The new owner sends proof of purchase to the manufacturer within 60 days of the sale, with a $300 transfer fee.

No. Metal Roofing New York does not install roofs and does not warrant the installation. Workmanship terms come from the installer and are written into their contract; the Guardian warranty does not cover workmanship.

It covers splitting, cracking and perforation of the panels from hailstones 1.5 inches in diameter or less. Other hail damage, such as cosmetic dents, is excluded.

The manufacturer warrants wind resistance up to 120 mph when installed to manufacturer specification. It is a warranty figure, not a building-code rating; the design wind pressure for your roof comes from the code that applies at your address.

Slate, Cedar Shingle, Shake and Mediterranean Tile, all in heavy-gauge aluminum.

No. Standing seam is outside the ICC-ES evaluation report for the system and is not offered through Metal Roofing New York.

Aluminum, 3105-H24 or 3003-H24 alloy to ASTM B209, with roughly 95% recycled content, finished in the Alunar® fluorocarbon (PVDF) coating system. Interlock Roofing makes the panels in North America.

Aluminum contains no iron, so it cannot rust, and there is no galvanized layer to wear through. It is also light: the ICC-ES report lists installed weights of 0.41 to 0.59 pounds per square foot for the aluminum profiles.

Yes. ICC-ES evaluation report ESR-1790 covers the aluminum Shingle, Diamond, Shake and Hidden Fastener Tile profiles for the 2009 through 2021 International Building Code and International Residential Code. The report is hosted on the proof page.

Class A Fire Rated Available, as a complete assembly: under ESR-1790 the roof is a Class A assembly when it incorporates GAF VersaShield® fire-resistant deck protection installed per ICC-ES report ESR-2053. Over a self-adhered underlayment the assembly is nonclassified.

Yes. UL 2218 Class 4, the highest impact class, verified by Intertek for Delta Building Products, on the Slate, Cedar Shingle, Shake and Mediterranean Tile profiles.

Under General Business Law section 771, the contract must be in writing and signed by the contractor, with a signed copy to you before work begins. It must show the contractor's name, address, phone number and license number, approximate start and completion dates, a description of the work and materials, and the price.

Yes. General Business Law section 771 requires the contract to tell you that you may cancel until midnight of the third business day after you sign, by written notice to the contractor.

New York requires the contractor to hold your deposit and progress payments in an escrow account or post a bond, and the contract must say so. Ask which one, in writing.

Not automatically, and most Long Island policies carry a separate hurricane deductible whatever the roof is made of. Ask your carrier what applies to your house.

No. Ice damming, and ice and snow shedding, are stated exclusions of the Guardian warranty. Ice dams come from heat loss into the attic and from ventilation, so ask the installer to look at both before the roof goes on.

Aluminum contains no iron, so it cannot rust. The Alunar® coating is warranted for 30 years against chalking and fading beyond stated limits under normal atmospheric conditions; corrosive, aggressive or industrial atmospheres are excluded. Read the coating terms in the warranty document.
