A Roof is your homes Main source of Protection against the elements
There will be signs…
No two roof repair jobs are the same due to when they were last remodeled, the level of expertise used during the last remodel or initial build of the property, and the location of the home; there can be differences in the amount of elemental wear and tear on a roof.
This means each individual homeowner needs to be alert and aware of their specific property needs, and check frequently for signs of damage that can save them large emergency repair costs in the future.
Even if your roofing shingles look ok dosen’t mean your roof is healthy enough to last the next winter..
At Oliwill Construction, with flexible financing options, we can jump-start your project while comfortably spreading the financial impact.
Bad Attic Ventilation
- The “Bake” Effect: Trapped hot air in summer cooks shingles from underneath, making them brittle and causing them to curl.
- Moisture Rot: Trapped winter humidity creates condensation that rots the plywood deck from the inside out.
- Balanced Airflow: Missing or blocked intake (soffit) and exhaust (ridge) vents ruin the system’s thermal balance.
- Freeze-Thaw Cycles: Water enters tiny cracks, freezes, and expands to shatter shingle integrity.
- Debris and Shade: Wet leaves and branches trap moisture, fostering algae, moss, and premature rot.
Flashing and Joint Failures
- Metal Breakdown: Valleys, chimneys, and wall transitions use metal pieces that rust, warp, or tear from temperature changes.
- Caulk Reliance: Cheap fixes rely on sealants instead of proper metal-to-metal overlap; caulk cracks within five to ten years.
- Hidden Leaks: Water slips behind faulty flashing and rots framing long before a stain appears on a ceiling.
Poor Installation Errors
- Overlaid Layers: Nailing a new shingle layer directly over an old one traps heavy heat and masks failing decking.
- Skipped Underlayment: Leaving out ice and water shields in vulnerable areas like eaves and valleys invites leaks during heavy rain or melting snow.
- Improper Nailing: Nailing too high, too low, or at the wrong angle prevents proper sealing and lets strong winds rip shingles off.
