Common Roofing Problems in Omaha, NE
If there’s one trait that Omaha’s weather doesn’t include, it’s subtlety. Its winters are numbingly cold, and its summers are sweltering. Its humidity isn’t limited to its occasional tropical systems. The higher your altitude, the wetter your weather. When temperatures rise to a 71-degree average, you don’t even need rain to experience water damage.
Sunset’s sudden cooling effects and moisture cause rapid expansion of your construction materials, giving condensate the perfect route beneath your outer roof. Years of expansion and contraction will ultimately ruin your structural integrity, and mold takes care of the rest.
When winter strikes, icy temperatures cause their own roofing woes. Wind and snow work together to dislodge your shingles, so it’s important to design your construction strategy for year-round climate chaos.
Dealing with Humidity
Trapped moisture destroys every part of your roof, from its attic floor joists and rafters to its sheathing. Given enough summers, wooden layers will eventually separate and weaken, creating even more space for moisture to penetrate. Mold and mildew are next in the queue.
You might think Omaha’s chilly winters are your greatest roofing threat, but root rot can be even more damning. It spreads rapidly, eating away at your bricks, ceilings, and plaster. Fungal and black mold infestations cause a domino effect that attracts ever-greater degrees of rot, but avoiding wooden materials won’t solve the problem. Gloeocapsa magma feeds on limestone, so those black streaks you see are more than just ugly—they destroy your shingles as well.
Metal is the material of choice for Omaha’s humid summers. It lets water and snow slide away easily, preventing ice dams and puddles of condensate. Clay tiles are even better, though. That’s why the National Association of Home Builders lists them as the most durable options on the market.
They’re naturally mold-resistant and lighter than concrete, so they reflect sunlight superbly. That way, your HVAC unit won’t have to work too hard to retain your indoor climate. You can expect clay, slate, and concrete roofing to last over a century, but Omaha weather demands a strategy that entails more than just the right materials.
The Importance of Ventilation
A little oxygen can cure a thousand ills, so your attic, sidewalls, and roofing membrane should all work together to encourage ventilation. A solid strategy can prevent heat loss and retain the integrity of your insulation. A breathable membrane is particularly important.
Air permeation can prevent water ingress and mold formation better than metal roofing can achieve on its own. It lets vapor travel beyond your build, so it’s the best way to handle your construction in humid Omaha weather.
Winter comes with an entirely new set of challenges. Hurricane winds can dislodge shingles while sleet creates heavy ice dams. Ice and water-resistant underlayment membrane will deal with the wetter parts of the season. Rubberized shingles act as a sheath that expands and contracts without breaking.
Clay and fiberglass are excellent choices for wind-resistance. Modern asphalt shingles aren’t as delicate as they once were, so they can cope with gales of 150 miles per hour. Metal pushes that resistance up to 160. If you remove high-pitched gables and large overhangs, your roof should survive decades, even when it’s assaulted by gale-force winds.
Weather-resistant roofing is one of the best ways to protect your home from Omaha’s climate. A good system can defend more than just your ceiling. It prevents siding, wall, and foundation problems while keeping your indoor climate stable. Its effects are so dramatic they’ll pay for themselves via return on investment when it’s finally time to sell your home.
