I looked into replacing my roof and found that with modern composite shingles I will end end replacing it numerous times in my lifetime. With Interlock it's one and done. The roof I got was red aluminum in a slate style and it looks great; best roof in my neighborhood, hands down. In fact it's fun to see cars driving by and notice the driver staring at the new roof. Also, I've received numerous compliments from passersby about how great the roof looks. Other points are that the install was quick and skillful and needless to say, I have no leaks. Positive, Professionalism, Services: Roof installation
I was initially apprehensive about the higher upfront cost of Interlock when compared to a basic composite shingle replacement, but three factors swayed me to give Interlock my business. First, the engineering behind the product is quite impressive. By that, I mean the way the panels interlock to form a tight, durable roof. Second, the roof looks great and will look the same for decades. Third, it’s a more environmentally sound solution by keeping my home cooler in the summer and also by being the last roof replacement the house will need. I have to say the installation crew was top-notch. They completed the job from tear-off to done in just over two days and left the gutters and yard cleaner than they found them. Admittedly my roof is small and fairly simple but to knock it out in two days during the triple-digit heat earned them my respect. All in all, I’d say I’m very happy with my new roof and the overall experience of working with Interlock.
Please consider this my letter of testimony regarding the installation of my beautiful Musket Grey Slate roof! From the beginning of this “roof project”, all of my conversations with Meg and Claudette were friendly and my questions were answered by these pleasant and knowledgeable ladies. Since I had already seen a presentation with a neighbor, Mike Rasmussen was able to save us both some time as I was very ready to get my leaky roof replaced! He thoroughly explained how the aluminum fits together and assured me the trained installers really did know what they were doing! Rolland called to let me know when he would be delivering the materials. He was right on time – even with snow and icy roads to contend with! He very neatly placed boxed materials next to the garage and then covered everything with a tarp to keep it dry. I was concerned with his and the installers’ safety during those unusual winter weather conditions but both Rolland and Peter seemed to take it in stride. Peter was very efficient and explained how things worked and answered my questions that I didn’t know I had until I watched how fast yet carefully he worked. Mike was right – Peter was quick and there was very little wasted material when he had completed everything! As it turned out, Peter was the only installer and he wasted NO TIME removing the chimney, getting my skylight replaced and the roof was done in only two days!! It was unusually COLD in Oregon those days; January 7th and 8th. He worked well into the dark evening hours on both nights, which I thought was above and beyond the call of duty. He carefully cleaned up after himself before he left. As you see, I am very impressed with my new roof. At one point, I was concerned that the aluminum may be “noisy”, however, with the amount of hard rain we have had, there is no more noise than there was with my old shingle roof. Again, I am impressed. My son is thrilled that he will never have to get up and toss laundry soap around on the roof to kill the moss! Just today, a gentleman stopped to chat about my roof as he’d noticed the sign in my yard. I happened to be outside for a few minutes and was happy to share my very pleasant experience with him. Neighbors have stopped to look at the sign and check out the roof on their walks. Enclosed are pictures of my “roof project”. Strangers would not know there ever was a chimney on the house. Peter was very careful removing the bricks which I appreciated since the new Leaf Guard system was recently installed. I thank you all for your help with updating my house. Please feel free to call me at 503-xxx-xxxx if you would like further comments.
I absolutely love my new roof. Damon my sales rep was fantastic and the installers were the height of professionalism3/8/2021So after the snow and ice storm last month my metal roof still looks great and for the first time in 22 years I didn't have to worry about losing shingles in the storm.

Metal Roofing FAQs for Homeowners in Timber
The following metal roofing FAQs are designed specifically for homeowners in Timber, Oregon. 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 Timber.
How does a metal roof handle Timber's heavy snow and freeze-thaw cycles?
Aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt, which absorbs heat unevenly and traps moisture. Timber receives about 76 cm of snow annually and experiences roughly 18 freeze-thaw days per year—conditions that accelerate asphalt cracking and ice-dam formation. Interlock's four-way interlocking panels and slick aluminum finish prevent water infiltration during these cycles, while the metal's thermal properties help shed accumulated snow safely. Snow guards are available if desired, giving you complete control over roof behavior.
With over 2,000 mm of rain yearly in Timber, how does metal roofing prevent leaks?
The four-way interlocking aluminum panels create overlapping seals that shed water continuously, and the system is engineered to ICC-ES ESR-1790 code compliance for water management. Timber's average 2,048 mm of annual rainfall demands a roofing material that channels water downward without pooling. Unlike asphalt shingles, which degrade under constant moisture exposure and develop gaps over time, Interlock's aluminum panels remain rigid and sealed. Installation over solid decking with underlayment ensures water flows away from your structure, not into it.
Why does aluminum resist rust better than steel in a rainy climate like Timber?
Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes in steel roofing. Instead, aluminum develops a self-healing oxide layer that protects the metal underneath, even when scratched. This distinction matters in Timber's wet climate: while steel requires ongoing maintenance and eventual replacement, Interlock's 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) remains structurally sound for decades. The Alunar 70% PVDF coating adds a secondary 30-year warranty against fading and chalk, safeguarding the aesthetic appeal alongside material integrity.
Do I need to reinforce my roof structure for a metal roof?
No structural reinforcement is required. Interlock's Slate profile installs at just 0.41 lb/sq ft and the Mediterranean Tile (the heaviest) at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. Most homes can support this weight on existing framing without modification. The lightweight design also means installation often occurs directly over an existing asphalt roof, eliminating costly tear-off labor and landfill fees. This approach is especially practical in Timber, where the wet climate makes winter removal messy and adds contractor expenses.
Can a metal roof withstand Timber's wind gusts?
Yes. Interlock panels are warranted to resist sustained winds up to 120 mph (193 km/h) when installed to specification, and Timber's typical wind gusts reach about 125 km/h—well within the rated envelope. The four-way interlocking design locks each panel to its neighbors on all four edges, distributing wind load across the entire roof system rather than concentrating stress on fasteners. This engineering approach means your roof strengthens itself under pressure, not weakens. For added confidence, the warranty covers wind-related damage if installation meets code.
What's the hail impact rating, and could it lower my insurance?
Interlock achieves UL 2218 Class 4, the highest impact classification available, with warranty coverage for perforation from hailstones up to 1.5 inches. Class 4 rating qualifies many homeowners for insurance discounts because impact resistance directly reduces claim likelihood. While Timber's climate favors snow over hail, the Class 4 rating provides peace of mind and documented proof of durability that insurers recognize. Check with your agent about potential savings—several carriers offer measurable premium reductions for Class 4-rated roofs, offsetting installation cost over time.
Is a metal roof fire-resistant in Oregon?
Interlock offers Class A fire classification because aluminum is non-combustible—it will not ignite or spread flame. This matters in Oregon's wildfire-prone regions and meets the strictest building codes, including IBC/IRC as verified by ICC-ES evaluation ESR-1790. A Class A roof also signals resilience to insurers and adds material value in fire-risk zones. Aluminum's non-combustible status means your roof actively protects your home rather than introducing fuel to a fire scenario, a fundamental difference from asphalt or wood-shake materials.
Will a metal roof help with cooling costs despite Timber's cool climate?
Yes, though the benefit in Timber's 11.1°C mean temperature is modest compared to hot regions. energy-efficient colors reflect solar heat with initial reflectance up to 0.55 and thermal emissivity of 0.84, meaning sunlight bounces away rather than absorbing into your attic. Timber receives about 2,809 sunshine hours annually, so each hour of summer sun represents wasted cooling if your roof absorbs it. The reflective finish also reduces summertime interior heat gain on south-facing walls, lowering air-conditioning load when needed and improving comfort. Over decades, this efficiency compounds.
Is a metal roof worth the upfront cost compared to asphalt?
Metal costs more initially but eliminates re-roofing cycles. Asphalt typically lasts 15–25 years and requires complete tear-off and replacement, generating landfill waste and labor costs each time. Interlock's Guardian Warranty covers the material for the lifetime of the original owner—non-prorated, transferable 50 years to the next owner. Over 50+ years, one metal roof replaces two or three asphalt roofs, avoiding compounded labor, disposal, and material costs. Current promotions include no payments and no interest until Spring 2027, or 10% off installation, making the transition more affordable. The single, permanent roof is the last roof you buy.
