Interlock® Aluminum Roofing — all-climates performance specs for South Hill, Washington
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
We just wanted to let you know how thoroughly-pleased we are with our new Interlock Roof. It is absolutely beautiful and we have had a lot of people stopping as they walk or drive by to admire how nice it looks. Everything progressed on the job exactly as you had shared with us when we signed the contract. There were no surprises. From the beginning when we got the call to set up a start date, to the final clean up and retrieval of the waste bin everything was handled so professionally. Viktor and Alex were a dream to work with-so-pleasant and each day everything was left so tidy that it would have been hard for guests to tell that we were in the middle of a re-roofing job. We will highly recommend your product and doing business with such a professional and obviously well run company.
I cannot think of anything as everything from presentation to completion of the roofing project went smoothly! I do get compliments on my new roof from Interlock- the red color and the slate look get rave reviews! I do recommend Interlock to anyone I meet that gives a compliment or says they are considering a new roof.
In 2004 my wife and I decided to purchase the lifetime Interlock Roof. I was fifty at the time and had been called over to my Father In Laws house several times to clean out his gutters and clean off his roof with a pressure washer. I told my wife I did not want our kids to have to do that for us in our later years.
I recommended someone. There was a rot in a board in my roof; the installation crew did not replace it and did not mention anything to me. I spoke to the instillation manager, Randal, and he said that the installation person would come back(This was a week ago).Ten minutes ago, I tried to call him and he did not answer. I am still trying to contact Randal, to replace the rotten wood. I am going to try to recommend people when ever I can; everyone asks about my roof when they see it.
Of the five name brand roofing contractors I screened for this project I chose Interlock and I am very pleased with the roof. Coordination and communication was critical especially since Interlock was to perform the installation immediately following another contractor performing a siding replacement.
Most of the other contractors had out that I was screening for the project covered a lot more as far as the structure and insulation as well as how the roof was a system as a whole and not just a shell. I didn't get as much information from Interlock.
They were stellar! There is nothing I would change!
When we are ready to do our roof we will be calling. We needed a quote
They could have improved their communication.
We are completly satisfied with the work and love our new roof. If you have any doughts about spending the money on this roof don't think twice, it is well worth the money. I wasn't there at the time
I liked the quality of the product and it looked good just too expensive.
