- Wind-performance tested to 193+ km/h (120+ mph) to resist severe gusts and windstorms that can affect Indian Summer and surrounding Thurston County neighborhoods.
- Advanced waterproof installation details and engineered underlayments reduce water intrusion during prolonged wet periods and intense storms.

Interlock® Aluminum Roofing — all-climates performance specs for Indian Summer, 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:
HELLO! I am Gerry from Olympia, Washington. A few years ago, I had my re-roofing done by INTERLOCK ROOFING SYSTEM for my house here in Olympia. I would like to thank the INTERLOCK ROOFING SYSTEM for the best, beautiful metal roof I ever had; the color choice never changed in spite of the weather condition here in Washington. So, if you want your home to deserving a thorough, keen, professional touch, quality, and professionalism, I would highly recommend INTERLOCK LIFETIME ROOFING SYSTEMS for your COMPLETE METAL ROOFING.
Their workers are very good and very capable. Fewer supply problems. Joe, the scheduler. He does an exceptional job keeping his customers happy and meeting schedules considering supply and covid issues. Always nice and courteous.
Dear Interlock Roofing, Thank you for coming by and installing a new roof on our house. After we first talked at the Tacoma Home Show in January, both Paul and Ross were fantastic in walking us through the process and explaining the roofing system when we met in February. They answered all our questions, and we were eager to get started. Patrick and Drew took the lead with the installation planning and paperwork, and once the materials were ready in May, Patrick dropped them off at our house. The three-man crew installed everything in three days and ensured any installation questions were answered and done properly. In the end, we love the look and expected longevity of our new roof.
The salesman was very knowledgeable. Once we decided that this proposal was too expensive for us, I feel bad about taking the salesman's time, but there's no way of knowing the expense until you have a sales presentation.
Everyone I talked with was punctual and professional just way too expensive for me to get ready to sell this place
The Interlock associate Ivan,came did an awesome service in correcting the part needed to be corrected, he left us with instructions of what we needed to check and to get in touch with, if needed 😀 Ms. May the associate answering the phone was helpful for us to get prompt service. They are dependable. We received roof service.
I'm still looking at the extremely high cost of the tile looking roofs.
Factory to installers communication, shipping, and their materials breakdown was the only problem we really had. The roof was pretty much wide open for about two weeks exposed to the elements. Loan company used, a pain to work with
They did a very good job! They did a good job. We have had a wind storm and rain, and no leaks.
By far the best purchase we've made for our home. Patrick and Greg were amazing! Installation was quick and there wasn't any mess left behind. If you have ever thought about getting a metal roof Interlock Roofing is hands down the best!
The cost of the roofing was too high. It looks very nice and glad I had it installed. I have one leak, but I haven't called them about it yet.
Interlok Reps came across as high-pressured and as if trying to 'pull fast ones'.
