Every Northeast Ohio winter brings the same call: water staining a ceiling, icicles hanging off the eaves, and a homeowner who doesn't understand why. The culprit is almost always an ice dam — and for contractors in the Greater Cleveland–Akron area, understanding how to prevent them is a chance to deliver real value and win more work this fall.

Ice dams cause serious, expensive damage, but they're largely preventable with the right materials and know-how. At Apollo Supply, we've supplied the roofing products behind winter-ready roofs since 1996, and we're here to help you keep your clients' homes protected.

What Causes an Ice Dam

An ice dam forms through a simple but destructive cycle. Heat escaping into the attic warms the roof deck and melts the snow on top. That meltwater runs down to the cold eaves and overhangs, where it refreezes into a ridge of ice. As more water backs up behind that ridge, it works its way under the shingles and into the home.

The result is damage that adds up fast:

- Water leaking into attics, ceilings, and walls
- Ruined insulation and interior finishes
- Damaged shingles, gutters, and fascia
- The risk of mold and long-term structural issues

The good news: address the root causes, and you can stop ice dams before they start.

The Three Keys to Prevention

Preventing ice dams comes down to keeping the roof deck cold and sealing out any water that does get through. That means focusing on three things.

- Insulation: Proper attic insulation keeps household heat where it belongs and off the roof deck, which is the first line of defense against the melt-refreeze cycle.
- Ventilation: A balanced ventilation system — intake at the soffits, exhaust at the ridge — keeps the attic and roof deck cold, so snow melts evenly instead of refreezing at the eaves.
- Ice and water shield: A waterproof membrane installed along the eaves and valleys creates a protective barrier, so even if an ice dam forms, water can't reach the deck.

Together, these three work as a system. Getting them right during a roof installation is far easier — and cheaper for the homeowner — than fixing water damage later.

Turn Winter Prep Into Fall Work

Ice dam prevention is a natural conversation to have with clients this time of year, and it opens the door to more business heading into winter.

A roof replacement is the ideal moment to build in protection — the crew can upgrade ventilation and lay ice and water shield while the roof is already open. For homes with a history of ice dams, you can offer targeted improvements to ventilation and insulation as a standalone service. Either way, you're solving a problem the homeowner genuinely worries about, and positioning yourself as the expert who understands why winter roofs fail.

That expertise is exactly what turns a one-time job into repeat business and referrals.
