IS YOUR ROOF AT RISK?
Learn 8 Signs That Your Roof Needs Repair or Replacement
The National Roofing Contractors Association (NRCA) recommends you do a roof inspection at least two times a year — spring and fall. This is why you should inspect your roof consistently, and contact a professional South Jersey roofer like Duane Mainardi Builders, LLC. to conduct a thorough roof inspection.
1. Leakage in Attic After Wind Driven Rain
Possible Cause:
- Leaky or Inadequate Shingle Underlayment
- Deteriorated Flashing
High winds can lift shingles’ edges (or other roofing materials) and force water and debris underneath them. Extremely high winds can cause extensive damage.
2. Leakage in Attic After Ice Build Up
Possible Cause:
- Inadequate Shingle Underlayment
Melting snow often refreezes at a roof’s overhang where the surface is cooler, forming an ice dam. This blocks proper drainage into the gutter. Water backs up under the shingles (or other roofing materials) and seeps into the interior. During the early melt stages, gutters and downspouts can be the first to fill with ice and be damaged beyond repair or even torn off a house or building.
3. Stains on Interior Ceilings and Walls or Mold and Mildew Growth
Possible Cause:
- Inadequate or Faulty Shingle Underlayment Allowing Leakage
When water gets underneath shingles, shakes or other roofing materials, it can work its way to the roof deck and cause the roof structure to rot. Extra moisture encourages mildew and rot elsewhere in a house, including walls, ceilings, insulation and electrical systems.
4. Blistering and/ or Peeling of Interior and/or Exterior Paint
- Excessive Temperature
- High Humidity Due to Poor Attic Ventilation
The blistering and/or peeling of paint can be a consequence to excess exposure to condensation. Condensation can result from the buildup of relatively warm, moisture-laden air. Moisture in a poorly ventilated attic promotes decay of wood sheathing and rafters, possibly destroying a roof structure. Sufficient attic ventilation can be achieved by installing larger or additional vents and will help alleviate problems because the attic air temperature will be closer to the outside air temperature.
5. Exterior Decay, Sheathing, and/or Siding
Possible Cause:
- Poor attic ventilation
6. Missing, Cracked or Curled Shingles
Possible Cause:
- Shingles Have Reached The End of Their Useful Life
The key to a roof system’s effectiveness is complete protection. When shingles are missing or torn off, a roof structure and home or building interior are vulnerable to water damage and rot. The problem is likely to spread-nearby shingles also are ripped easily or blown away. Missing or torn shingles should be replaced as soon as possible.
7. Dark, “Dirty-Looking” Areas on Your Roof (Shingle Deterioration)
- Loss of Granules Due to Age of Shingles
When shingles are old and worn out, they curl, split and lose their waterproofing effectiveness. Weakened shingles easily are blown off, torn or lifted by wind gusts. The end result is structural rot and interior damage. A deteriorated roof system only gets worse with time-it should be replaced as soon as possible.
8. Excessive Energy Costs
- Insufficient Attic Ventilation Causes Heating/ Cooling System to Run Excessively
