FAQs
1. What is a metal-over-shingle roofing system and how is it installed?
A metal-over-shingle system allows us to install a new, lightweight steel or aluminum roof panel assembly directly over your existing asphalt shingles. First we inspect and repair any damaged decking from inside the attic, then we add underlayment and corrosion-resistant furring strips or a vented panel that creates an air gap between the old shingles and the new metal. The panels are then fastened through the strips into structural members, providing a secure, code-compliant roof without the mess and cost of a full tear-off.
2. Is it legal and safe to put metal roofing over shingles in Harriman?
Yes. Harriman follows the 2018 International Residential Code (IRC) and local amendments, which permit one additional roof layer as long as the existing shingles are sound, the structure can carry the load, and proper ventilation is maintained. Our team pulls the required city or county permit, documents structural capacity, and installs manufacturer-approved underlayment so your new roof meets or exceeds local wind-uplift (up to 140 mph) and fire-rating standards.
3. Will the extra weight stress my home’s framing?
No. A typical 26- or 29-gauge steel panel weighs 0.9–1.3 lb per square foot. Even after adding furring strips and fasteners, the combined weight of metal plus shingles is usually 2–3 lb/ft²—still far lighter than two layers of asphalt or most tile products. Before we begin, we inspect your rafters/trusses and confirm load calculations, ensuring your home easily supports the new roof.
4. How does a metal-over-shingle roof handle Harriman’s weather?
Harriman sees hot, humid summers, heavy thunderstorms, and the occasional winter ice event. High-strength interlocking metal panels shed rain quickly, resist hail impact, and carry class-A fire ratings. The reflective pigment reduces attic temperatures by up to 40 °F in summer, lowering AC costs, while the created vent space under the panels helps melt snow and dry out moisture, preventing ice dams and shingle decay.
5. What are the cost and environmental advantages compared with tearing off the old roof?
Skipping tear-off saves roughly 20–30 % in labor and disposal fees alone, often shortening the installation timeline by two to three days. It also keeps 3–5 tons of asphalt shingles out of the landfill. Because the metal reflects solar heat and can qualify for ENERGY STAR® tax incentives, many homeowners recoup the price difference through lower utility bills and insurance discounts within 5–10 years.
6. What maintenance and warranty coverage can I expect?
Metal roofs require only periodic rinsing to remove pollen and debris, plus a quick fastener check every 5–7 years. Our steel and aluminum panels carry a 40- to 50-year manufacturer’s finish warranty against chalk and fade, a 30-year limited warranty against rust, and a 5-year workmanship guarantee from our Harriman crew. With no granules to shed and no organic material to rot, most customers enjoy a service life of 60 years or more with minimal upkeep.
