Your roof is your home’s first line of defense against Michigan’s unpredictable weather—be it heavy snow, ice storms, spring showers, or blazing summer sun. Yet, too many homeowners unknowingly make decisions that compromise the safety, efficiency, and longevity of their roofing system.
At Horizon Roofing and Construction, we’ve seen firsthand how preventable roofing mistakes can lead to costly repairs or even premature replacements. Here are seven of the most common roofing mistakes Michigan homeowners make—and how to avoid them with expert help.
Why Roof Mistakes Cost More Than You Think
Roofing errors aren’t just cosmetic or inconvenient—they can lead to serious structural issues, escalate energy costs, and even void your roof warranty. In Michigan, these risks are magnified by extreme seasonal temperature swings, snow load, and freeze-thaw cycles. What may seem like a minor oversight in the summer could become a major leak during a January blizzard.
Proactive roof maintenance, reliable materials like the CertainTeed roofing system, and working with certified professionals can prevent these headaches. Let’s dive into the most common missteps.
1. Ignoring Early Signs of Roof Damage
Leaks, stains, and missing shingles
Michigan’s weather can be brutal on shingles. It’s common for homeowners to discover missing or lifted shingles after a heavy windstorm. Other early signs include ceiling stains, attic dampness, or small drips that appear during rain.
How early action saves money
The longer you wait to address minor issues, the more extensive—and expensive—the damage becomes. Prompt roof repair can stop water from infiltrating insulation, rafters, and drywall. A free roof evaluation by Horizon Roofing can identify issues before they escalate.
2. Choosing the Cheapest Bid Without Due Diligence
Price vs. value in roofing
We understand the desire to save money, especially when facing a large expense like a new roof cost. But choosing a contractor based solely on price often leads to subpar workmanship, low-grade materials, or even incomplete projects.
How to vet a contractor properly
Do your homework. Ask for licenses, insurance, and references. Check reviews and verify the contractor’s certifications. At Horizon Roofing, we’re proud to be CertainTeed-certified installers, offering manufacturer-backed warranties and proven expertise.
3. Delaying Roof Replacement Past Its Prime
How age and wear impact protection
All roofs have a lifespan. Asphalt shingles typically last 20–30 years, but harsh winters and poor ventilation can shorten that. If your roof is nearing the end of its life, frequent patchwork becomes less effective.
The cost of waiting too long
Ignoring signs that your roof needs to be replaced can lead to rotted decking, mold, and increased insurance claims. In worst-case scenarios, it may even compromise your home’s structural integrity. Investing in a new roof on time avoids larger restoration costs down the line.
4. Skipping Professional Roof Evaluations
Why free inspections are essential
Even if your roof looks fine from the ground, hidden problems may be developing underneath. A professional inspection can catch soft spots, flashing failures, and ventilation blockages that might go unnoticed.
What a certified contractor looks for
At Horizon Roofing, our evaluations include a full inspection of shingles, flashing, gutters, soffits, insulation, and attic airflow. We use drone footage, moisture meters, and years of local knowledge to ensure no issue is missed.
5. Poor Roof Ventilation or Insulation
Michigan winters and attic moisture
Many homeowners don’t realize that poor attic ventilation can lead to ice dams, mold, and premature shingle failure. In winter, warm air trapped in your attic melts snow, which refreezes at the roof’s edge, causing backups and leaks.
The link between airflow and roof lifespan
Proper insulation and ventilation allow heat and moisture to escape, which protects your roof deck and improves energy efficiency. We’ll ensure your attic meets code requirements and supports your roof system year-round.
6. DIY Repairs or Hiring Unlicensed Contractors
Common DIY roofing failures
From improperly nailed shingles to incorrect flashing installation, DIY roofing jobs often cause more harm than good. Roofing is a specialized trade that demands training, tools, and safety equipment.
Warranty issues and safety risks
Most roofing material manufacturers require certified installation to honor warranties. Hiring an unlicensed contractor—or tackling repairs yourself—could leave you on the hook for thousands if something goes wrong.
7. Not Preparing for Michigan’s Storm Season
How weather-specific preparation matters
Michigan roofs must be ready for intense winds, hail, ice, and torrential rains. Roofs without proper flashing, drainage, or weatherproofing are vulnerable to leaks and structural damage.
Upgrades like ice and water shield, flashing, and proper drainage
Modern materials like ice and water shields, drip edge flashing, and robust gutter systems can prevent storm-related issues. Our team installs these protections as part of every roof replacement or upgrade.
