★★★★★
Review: January 6, 2018

The reason I won't be using Interlock is that at my age and the cost of a new Interlock roof system I can't justify putting on a $30K+ roof when I have other home priorities. If I was 20 years younger and still working I wouldn't hesitate putting an Interlock roof system on.

Metal Roofing FAQs for Homeowners in Longbranch

The following metal roofing FAQs are designed specifically for homeowners in Longbranch, Washington. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Longbranch.

How does a metal roof handle heavy snow and ice in Longbranch winters?

Metal roofs shed snow and ice far better than asphalt because the smooth, hard surface offers no grip. Longbranch gets about 40 cm of snow yearly plus around 34 freeze-thaw cycles, which means ice dams form easily on conventional roofs as melting snow refreezes at the eaves. Interlock's four-way interlocking aluminum panels stay slick in those conditions; you can add snow guards if you want to control the slide. The metal surface won't degrade from repeated freeze-thaw stress the way asphalt shingles do.

Why should I choose aluminum metal roofing instead of steel in a rainy climate?

Aluminum simply cannot rust because it contains no iron—the element that oxidizes and creates rust. Steel roofs require protective coatings to prevent rust, and those coatings eventually fail. Longbranch receives roughly 1370 mm of rain annually, which means constant moisture. Interlock uses roofing-grade 3105-H24 aluminum with a Alunar 70% PVDF fluorocarbon finish on both sides for extra protection in salt-air and wet conditions. If the coating scratches, aluminum's oxide layer self-heals; steel's does not.

Are metal roofs prone to leaking in heavy rain?

No—in fact, metal roofs are among the most leak-resistant options available. Longbranch averages 1370 mm of rain yearly, and the four-way interlocking design of Interlock panels creates multiple barriers that shed water downward and outward. The panels lock together so tightly that water cannot find a pathway into the structure. Metal roofs installed over a solid deck with proper underlayment perform identically to asphalt in rain tests, but they remain watertight for decades without the degradation that causes asphalt leaks.

Can a metal roof withstand Pierce County wind gusts?

Yes, reliably. Longbranch experiences typical daily winds around 16 km/h with gusts reaching 99 km/h, and Interlock's four-way interlocking aluminum panels are engineered to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The interlocking design means each panel is mechanically locked to its neighbors on all four sides, so wind cannot get underneath or lift a panel. This design is why Interlock roofs have been installed from coastal salt-air homes to Antarctica without wind failure.

Do I need to reinforce my house structure for a metal roof?

No structural reinforcement is needed. Interlock's aluminum panels are extraordinarily light—the Mediterranean Tile profile, which visually replicates heavy clay tile, weighs only about 0.59 lb/sq ft and is roughly 96% lighter than the real tile it copies. Most homes can install Interlock panels directly over existing asphalt without any structural work. This is especially valuable in Longbranch, where you can often avoid the cost and hassle of structural upgrades that concrete or clay tile would demand.

What does Interlock's warranty actually cover, and for how long?

The Guardian Warranty is non-prorated for the original owner, meaning there's no decline in coverage year to year—it simply doesn't expire as long as you own the home. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance; the coating itself is warranted 30 years against chalking and fading under ASTM D4214 and D2244 testing. Even better, the warranty is one-time transferable to the next owner, giving them 50 years of protection from the completion date. This peace of mind is especially valuable in Longbranch's freeze-thaw environment, where material fatigue is a real concern.

How much maintenance does a metal roof need?

Virtually none compared to asphalt, wood shake, or clay tile. Asphalt requires inspection every few years, wood shake needs regular treatment to prevent splitting and rot, and tile requires reseating and repair work. Interlock aluminum roofs are CALGreen-verified for reduced maintenance—you simply rinse off debris twice a year if you live in a wooded area. In Longbranch's 2881 annual sunshine hours and heavy rainfall, your roof experiences both UV exposure and moisture cycling, but the Alunar 70% PVDF finish on both sides resists chalking and fading without needing touch-ups or repainting.

Is metal roofing really the last roof I'll install?

Yes, because the economics favor it over the roof's life. An asphalt roof in Longbranch lasts 15-20 years; you'll replace it 3-4 times over 60 years, paying demolition, removal to landfill, and installation labor each time. Interlock's non-prorated lifetime warranty means one installation covers you and transfers to the next owner with 50 years of additional protection. The current promotion—no payments and no interest until Spring 2027, or 10% off—also eliminates the financing sting. When you factor in asphalt's recurring tear-off costs, metal roofing becomes the lowest-cost option.

Will a metal roof help me save on cooling costs?

In summer months, yes—Interlock's energy-efficient colors reflect heat rather than absorb it the way dark asphalt does. The Aged Copper Penny finish achieves solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning it bounces solar radiation away and reradiates heat efficiently. Longbranch's 2881 annual sunshine hours provide plenty of opportunity for this reflectance to reduce cooling load. You won't see savings in winter—metal conducts cold the same way asphalt does—but the Cool Roof Rating Council certification confirms the summer benefit is real and measurable.

Does a metal roof protect my home from wildfire embers?

Metal roofing eliminates the ember-ignition risk entirely. Interlock aluminum is non-combustible and available with Class A fire classification—the highest fire rating available. This is particularly relevant for Pierce County homeowners near wooded areas, where airborne embers from distant fires can ignite conventional roofing. Aluminum cannot catch fire, cannot smolder, and cannot release flaming debris if exposed to embers or flame. An ICC-ES evaluation report (ESR-1790, reissued 2025) confirms compliance with fire safety codes, making metal roofing the prudent choice in wildfire-prone regions.

Is a metal roof a good choice for Longbranch’s climate?

Yes. Longbranch averages about 40 cm of snow, 1370 mm of rain, roughly 34 freeze–thaw days a year, with peak wind gusts near 99 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
