Never Re-Roof
Again.®
One decision removes roofing from your life for good — no exposed lap seams for backed-up meltwater to find, no curling shingles, no $30k replacement every 20 years. Guaranteed in writing: The Guardian Warranty, lifetime coverage — and if you sell, the next owner is covered to 50 years.
What changes the day your Interlock roof goes on.
Salt air stops mattering
Aluminum can't rust — ever. Coastal homes keep their roof and their looks while steel and asphalt neighbors replace theirs.
Ice dams become someone else's problem
Four-way interlocked panels shed snow before it ponds — no heat cables, no February roof rakes, no ceiling stains.
Recycled aluminum
The last tear-off your house will ever see — nothing to the landfill every 15 years.
The look upgrades, the house doesn't strain
Slate and cedar character at a fraction of the weight — no structural work, no compromise.
Your home is worth more the day you sell
A lifetime warranty that transfers to the buyer — covered to 50 years from install — becomes a listing feature.
We don't say lifetime lightly.
We can show you the roof.
The math nobody shows you.
What New England's popular roofing materials actually deliver over the life of your house — not over the length of a sales pitch.
