Roof Maintenance Checklist

Is your roof giving you peak performance?

Knowing your roof's makeup and condition can help prevent problems before they occur. Here are some ways to help you protect your roof so it can continue to protect you.

Proper attic insulation and ventilation can save your roof from warping, decrease your energy costs and reduce the amount of moisture in your home. It also prevents snow and ice from melting and refreezing, which can cause water damage to your roof and home.

Before installing new shingles, have your contractor ensure you have a solid roof deck so it will not move or deteriorate.

Make sure proper flashing is installed, particularly around vents and chimneys to help prevent interior water damage.

Keep your gutters free from debris. Make sure their outer edges are lower than the roof's slope line to allow snow and ice to slide clear.

Roof repairs and replacement

Signs of an aging roof that may need work include:

  • Curling along the bottom edge, particularly during cold weather.
  • Surface cracking resulting in increasingly brittle shingles.
  • Blisters, which could indicate a manufacturer defect or poor ventilation.

Roofing contractors

It's important to hire the right roofing contractor. Here are some questions to ask during your search:

  • How long have you been in business?
  • Are you bonded and insured, including workers' compensation and general liability?
  • Do you have the appropriate licenses in your community?
  • Can you provide names and phone numbers of customers I can call for a reference?
  • Do you have a satisfactory record with your local Better Business Bureau?
  • Are you willing to put all agreements, promises and understandings in writing?

Remember, the cost to replace a roof varies according to the market, roofing materials, the roofing contractor, the steepness of the roof, the area to be covered and other factors.

Additionally, the life expectancy of a roof varies according to factors such as age, exposure to the elements and roof type.
