Yes, ice dams happen — in the East Mountains

Tijeras, Edgewood, and Sandia Park get cold enough that ice dams form on poorly ventilated roofs.

Ice dams happen when attic heat melts snow, the meltwater runs down to the cold eave, and refreezes — backing up water under the shingles.

The fix is never heat tape alone. It's a combination of attic insulation (R-49 minimum), balanced ventilation, and an ice-and-water shield underlayment extending at least 24 inches past the interior wall line.

If you live above 6,500 feet and your roof predates 2010, get the underlayment checked before next winter.

What people say after James walks their roof

Three roofers wanted $32k after the June hailstorm. Roof Doctor NM walked the roof, took 84 photos, and said the hail was cosmetic. Saved me from a fraudulent claim.

Under contract on a Corrales house. The pre-purchase report caught two hidden layers the seller's disclosure missed. Got an $18k credit at closing.

Bid review flagged that the 'lifetime warranty' voided if we used the wrong underlayment — which the contractor had specced. Renegotiated the whole scope.
