Your roof is your home’s first line of defense against the elements—and keeping it waterproof is essential to preserving your property’s structure and interior. While professional maintenance is always recommended, there are several DIY steps you can take to boost your roof’s resistance to water damage. For homeowners in Bloomfield Hills, MI, where rain, snow, and fluctuating temperatures can cause issues year-round, these practical waterproofing tips can help prevent costly repairs.


Start With a Roof Inspection

Before taking action, you need to know what you’re working with. Begin with a visual inspection from the ground using binoculars or, if safe, climb onto the roof for a closer look. Check for:

  • Missing, curling, or cracked shingles
  • Rusted or loose flashing around chimneys and vents
  • Clogged or sagging gutters
  • Moss, algae, or debris buildup


Pay special attention to roof valleys, around skylights, and other penetration points where water is more likely to seep in.


Clean Your Gutters and Downspouts

Clogged gutters are one of the top causes of roof leaks. Leaves, dirt, and debris prevent water from flowing properly, causing it to back up under the roofline or spill over onto your siding and foundation. Clean gutters at least twice a year, and consider adding gutter guards for ongoing protection.


Make sure downspouts are securely connected and directing water at least 3–4 feet away from your home’s foundation.


Repair Shingle Damage Promptly

If you find a few damaged shingles, you can replace them yourself using roofing nails and roofing cement. Slide a new shingle into place and secure it beneath the overlapping layer above. Seal edges with cement to prevent wind and moisture from getting under the replacement.


For larger areas of damage, call a professional to ensure repairs are watertight and up to code.


Seal Roof Flashing and Joints

Roof flashing seals the most leak-prone areas, like chimneys, skylights, and vent pipes. If flashing is rusted, loose, or missing, it should be replaced. For smaller gaps, you can apply a high-quality roofing caulk or sealant to patch holes or reinforce seams temporarily.


Be careful not to rely solely on caulk for long-term fixes—permanent flashing repairs should be left to a licensed roofer.


Apply Roof Sealant or Coating

Roof coatings are available in waterproof, UV-reflective formulas that extend the life of your roofing materials. Products like elastomeric roof coatings form a flexible barrier over your roof that expands and contracts with temperature changes—ideal for climates like Bloomfield Hills, MI.


These coatings are typically applied with a roller or sprayer and are best suited for flat or low-slope roofs. Always clean the surface thoroughly before application.


Keep the Attic Ventilated and Insulated

Poor attic ventilation can lead to moisture buildup, which causes wood rot, mold growth, and ice dams in winter. Ensure your attic has adequate soffit and ridge vents to maintain airflow. Adding insulation also helps regulate temperature and prevent condensation.


A dry, well-ventilated attic works in tandem with your roofing system to keep your home watertight and energy-efficient.


Trim Nearby Trees

Overhanging tree branches can scrape shingles, clog gutters, and drop debris that holds moisture. Trim branches at least 6 feet away from your roof to prevent damage during storms and reduce the chance of critters finding a pathway to your roof.


Know When to Call a Professional

While these DIY tips go a long way, some tasks require professional expertise.
