Winter months can be cruel to your roof, as it is the first line of defense against the high winds, heavy rains, sleet and snow that are typical of many winter months. And if your roof fails, it can cause great expense, significant damage and wasted time and money. So when the weather is better, it’s a good idea to perform a quick check-up to insure that your home is protected.

Leaking roof systems can result from several sources. The most common leak sources include cracks in flashing around the chimney and vents, worn out or missing shingles, or condensation from inadequate attic ventilation. Here are some suggested warning signals that your roof system may be wasting money and leaving your property vulnerable that you can identify yourself, according to Dave Harrison, Senior Vice President of GAF Materials Corporation, North America’s largest roofing system manufacturer:

• Ceiling spots – A warning sign that your roof system needs leak repair.
• Missing shingles – These should be replaced quickly to avoid structural damage to your roof deck and the interior of your home.
• Cracked flashing – Should always be replaced.
• Buckled or curled shingles – Indicates old age or a problem with the shingle underlayment (i.e., the felts underneath the shingles).
• Blistered shingles – Typically occurs due to inadequate roof ventilation or application over a wet deck.
• Granules in the gutter – If excessive, it may indicate aging shingles that should be replaced.
• Peeling of interior or exterior paint/wallpaper – A sign of possibly inadequate attic ventilation.
• Excessive energy bills – Especially air conditioning in the summer, can be a sign of inadequate attic ventilation.

If you have issues with your roof system, consider utilizing the services of a professional roofing contractor. Most people think roofing is simple, and are therefore willing to hire a “fly-by-night contractor” to perform their roofing services, often at a lower cost. This is probably why roofing is one of the top reasons for complaint calls to the Better Business Bureau.
