If you need a roofer in laurel maryland that understands why local shingles are cracking this winter, you’ve come to the right place.
In Laurel, our winters are defined by a relentless back-and-forth between mild afternoons and frigid nights. While many regions experience a deep, consistent freeze, Laurel’s proximity to the Atlantic and its Mid-Atlantic positioning create a volatile climate where the temperature frequently dances around the freezing mark. During a typical January day, you might see a high of 42°F or even 45°F under the sun, only for the mercury to plummet to a low of 25°F once the sun sets. This constant fluctuation—thawing during the day and refreezing at night—is the engine behind the “Maryland Freeze-Thaw” cycle that puts immense stress on your roofing materials.
What is the “Maryland Freeze-Thaw” Cycle?
In Laurel, we rarely get a “frozen” winter that stays below freezing. Instead, we deal with a rollercoaster: it’s 45 degrees and sunny at noon, but 25 degrees by midnight.
This back-and-forth is the freeze-thaw cycle, and it is arguably more damaging to your roof than a massive snowstorm. Here is how it works:
-
The Thaw: During the day, snow on your roof melts. This water trickles into the tiny, microscopic pores and hairline cracks of your asphalt shingles.
-
The Freeze: At night, that water freezes. As water turns to ice, it expands by roughly 9%.
-
The Damage: That expansion acts like a tiny crowbar, prying apart the granules and fiberglass mat of your shingles. Over dozens of cycles in a single winter, those “micro-cracks” become visible splits.
Why Shingles are Cracking More This Year
If you’ve noticed more grit in your gutters or visible cracks on your roof, you aren’t alone. This season’s specific weather patterns have accelerated three major issues:
1. Thermal Splitting (Tearing)
When temperatures drop rapidly, shingles contract. If they are older or have lost their natural oils, they become brittle. Instead of flexing, they “snap,” creating long horizontal or vertical cracks known as thermal splitting.
2. Ice Dam “Back-Up”
When water freezes at the cold edge of your roof (the eaves), it creates a dam. New meltwater pools behind it and sits on your shingles. The longer that water sits, the more chances it has to freeze under the shingle, lifting it up and breaking the sealant bond.
3. Granule Loss
The constant expansion of ice on the surface of the shingle “scrubs” away the protective granules. These granules are what protect your roof from UV rays; once they’re gone, the sun bakes the asphalt, making it even more prone to cracking during the next freeze.
