Your roof is designed to protect your home—but it can’t do its job forever without attention. The signs of roof trouble are often subtle at first, but they can quickly escalate into expensive problems if ignored. As a homeowner in Bloomfield Hills, MI, knowing when to call a roofer could be the difference between a simple repair and a full replacement. At
180 Contractors Roofing & Siding, we’ve helped countless local homeowners catch early warning signs before things got out of hand. Here are five major indicators that it’s time to call a professional roofer.
1. Water Stains or Leaks Inside Your Home
One of the clearest signs your roof is failing is the presence of water where it doesn’t belong. If you notice dark spots on your ceiling, damp patches on your walls, or worse—dripping water—it’s a strong indicator that your roof has been compromised.
Leaks might originate from damaged shingles, cracked flashing, or even a worn-out underlayment. Left untreated, water damage can spread quickly, leading to rot, mold growth, and ruined insulation. Early detection and fast action are key to minimizing repair costs.
2. Missing, Cracked, or Curling Shingles
Shingles are your roof’s first line of defense. When they begin to break down, your entire roofing system becomes vulnerable. Look for areas where shingles have:
- Gone missing entirely
- Curled or cupped at the edges
- Cracked down the middle
- Lost their granules (check gutters for buildup)
These signs typically appear after harsh weather events, like snowstorms or hail—a common occurrence in Bloomfield Hills. Our experts at 180 Contractors Roofing & Siding offer thorough inspections to determine whether repair or replacement is the best solution.
3. Sagging Roof Lines
A sagging roof is more than just an eyesore—it’s a structural red flag. This condition can indicate that the decking beneath your shingles has absorbed moisture and begun to rot, causing the surface to sink.
In serious cases, sagging may signal a failure in your roof’s framing system. If you notice any drooping or uneven areas on your roof, call a professional immediately. Addressing this early can prevent collapse and costly reconstruction.
4. Moss, Algae, or Dark Streaks
Green moss and dark streaks on your roof might look harmless, but they signal hidden moisture retention. Moss in particular trap water against your shingles, leading to premature deterioration. Algae and mold, meanwhile, point to poor ventilation and potential rot in your roof decking.
Regular cleaning can help, but the presence of recurring growth often indicates a deeper issue with moisture management or ventilation. We install and upgrade systems using high-performance materials like those from Owens Corning, helping keep your roof healthy from the inside out.
5. Your Roof Is 15–20 Years Old (or Older)
Even the best-installed asphalt roofs have a limited lifespan. If your roof is approaching the 20-year mark—or older—and you’re starting to see wear and tear, it’s time to schedule a professional inspection.
Many homeowners wait until visible damage occurs, but proactive inspections and preventative maintenance can extend your roof’s life and help you budget for future upgrades.
Bonus: Increased Energy Bills
A failing roof can compromise your home’s insulation and ventilation, forcing your HVAC system to work harder to regulate indoor temperatures. If you’ve noticed a steady rise in heating or cooling costs without changes in usage, your roof may be the culprit.
Our team can evaluate your attic insulation, ventilation system, and roofing materials to pinpoint energy efficiency issues—and recommend affordable, high-impact upgrades.
Don’t Wait Until It’s Too Late
Roof problems rarely fix themselves. What starts as a minor issue can quickly snowball into thousands of dollars in damage. When you recognize the warning signs, don’t delay—get professional eyes on the problem and take action.
At 180 Contractors Roofing & Siding, we offer honest evaluations, high-quality repairs, and complete roof replacements backed by strong warranties and trusted craftsmanship.
