Common Roofing Problems in Des Moines, IA

Des Moines roofing

When Mother Nature visits Iowa, she rages. Tornadoes, hail, and blizzards make frequent appearances on local weather reports. Des Moines is a particularly wet region that endures precipitation 108 days a year. Rain, sleet, and snow wreak havoc on your roofing, forming leaks and ice dams that shorten the lifespan of your shingles. With the right strategy, however, you can meet those challenges head on.

Overcoming Tornados

Des Moines endures 40 to 50 stormy days each year. When tornadoes rip through the countryside, they expose your roofing to ice, rain, and flying debris. Ordinary roofing just won’t do. Tornado resistance can only be achieved with products that are built for severe weather events. Stone-coated steel shingles have a reputation for being one of the few tornado-resistant options on the market today. They can tolerate winds of 120 miles per hour.

Reducing Wind Grab

Your shingle placement strategy is as important to wind resistance as your materials. Metal panes can resist gale-force winds best when they interlock, overlap, and are attached in X-patterns. You needn’t swear off asphalt, though. Today’s asphalt shingles are more durable than ever before, particularly if they’re properly fastened and coated.

A single raised shingle can compromise the integrity of your entire roof, so each component should be fastened above and below the overlap. Small overlaps of an inch or less will encourage wind damage.


Blinding snow and freezing rain frequently rip through the blizzard belt, so ice dams are one of Des Moines’ worst roofing problems. When they aren’t loosening gutters and shingles, they’re warping your ceilings. Sagging and soggy insulation are the vestiges of every roofing nightmare, and that’s before mold and mildew settle in. Heated cables can certainly help, but you’ll need a more permanent solution.

Attic heat is the nemesis of the ice dam universe. If the underside of your roof surface is close to the outdoor temperature, you can relegate this problem to the past.

Ventilated eaves keep cold air in circulation while warming your roof so that snow melts away without leakage. Your system should cover a square foot of free ventilation for every 150 square feet of attic space.

Impact Damage

Hail and flying debris can cause granule loss on asphalt, exposing your roofing to leaks. Rubber roofing is a practical alternative that can sustain incredible force without breaking down.

Steel is another popular solution that’s both hail-resistant and heat reflective. It can tolerate hailstones of over 1.5 inches in diameter. Add a premium coating, and you have a roof that will survive decades of Iowa storms.


De Moines’ notorious heat waves strike 40 days a year, so blistering is a common roofing problem. Inferior coating systems blister in extreme sunlight when air pockets expand between your roof’s adhesives and shingles. This creates a pathway for moisture, which in turn causes more blisters. Frequent inspections let you address the problem before it becomes catastrophic, but prevention is always preferable.

Asphalt shingle coatings are particularly prone to blisters, but new products are far more resistant. If your asphalt is reaching the end of its lifespan, a simple replacement will give you excellent results.

In days of yore, shingle ingredients were manually fitted, so bubbles were a frequent complaint. Automated technology has overcome that problem, so modern products are far less prone to over-heating.

Des Moines’ harsh climate does little for worn, eroded shingles, but there are several excellent solutions. It’s time to put roof nightmares in the past where they belong. An intelligent strategy and skilled roofing company are all you need to survive those tough autumn storms.
