Interlock® Aluminum Roofing — all-climates performance specs for Greenwood, Nova Scotia

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

What our customers are saying:

★★★★★
Review: December 11, 2020Completion: November 17, 2020

I was happy to see that the work was done effectively, the installers were well-informed, courteous and did quality work. Very pleased! I had the dumpster in my driveway for 13 days which was rather inconvenient.

★★★★★
Review: February 5, 2022Completion: January 19, 2022

The materials used are of good quality and professionally installed. Very pleased with the completed work.

★★★★★
Review: February 5, 2026Completion: August 26, 2025

Maritime Metal Roofing Ltd. provided a completely professional experience on our metal roofing project in Kentville, NS, with excellent communication throughout the process and an efficient installation team.

★★★★★
Review: May 7, 2021Completion: March 21, 2021

The cleanup and the communication with the installers could have been better.

★★★★★
Review: June 11, 2015Completion: May 26, 2015

None. There is a little bit of disconnect in communication. I was talking to the guy who's in the office in Dartmouth or Halifax and I told him that I got a call from the states and he said that they didn't have anything to do with anyone in the states, so I was concerned if you were actually a valid organization or not.(I explained to her what GuildQuality is and assured her that we are in fact a valid company.)

★★★★★
Review: January 13, 2026Completion: March 8, 2009

We recently had extra snow guards added to our roof. The workers that showed up, were professional and dedicated, it was Saturday evening, they were all smiles and very polite.

★★★★★
Review: August 24, 2021Completion: July 1, 2021

Interlock Roofing has an excellent product and is very competitive for a "lifetime" metal roofing solution. Well worth the extra costs for a superior product.

★★★★★
Review: March 30, 2016Completion: March 30, 2016

Again, as long as that missing step gets completed I give this a 4. For now, I will say 3.6. It would have been if they had taken care of that one ommitted step, but they said they will take care of it.

★★★★★
Review: February 14, 2024Completion: January 18, 2024

The communication fell short of my expectations. We had a windstorm, and they did not put the underlay down correctly. It was installed with only a few nails, and we had to listen to it flapping all night.

★★★★★
Review: August 21, 2017Completion: July 31, 2017

receiving just the flashing in advance so I could renovated the wall without put pressure on the installation crew

★★★★★
Review: April 14, 2016Completion: April 14, 2016

I don't know how the company could have improved. The only thing is that I thought they were going to leave us a sign for our lawn as an advertisement. We didn't get one.

★★★★☆
Review: April 13, 2022Completion: March 24, 2022
