M2=H2: R is for Roof

A roof is a system of your home which is designed to last a long time, if you take proper care of it. Areas which require periodic attention include flashing, drainage waste vent stacks, shingles and gutters. To be sure everything is working as it should, you should have a professional roofer examine these areas every three years. Let’s examine each area to see what to watch for.

Roofs

FLASHING: Flashing is metal, plastic or rubber pieces which protect your roof wherever there is a join – between roof and chimney, between dormers and roof or in valleys where two different roof slopes meet. These pieces ensure that no water infiltrates those areas. Usually, metal and plastic flashing will last as long as your roof does and will not need replacing until replacing your roof.

DRAINAGE WASTE VENT STACKS: These vents are the white pipes which protrude from your roof. They are designed to allow air to help your waste water flow without impediment. The vents are very durable, but the special flashing around them, called a “boot,” is not. Boots are typically made of rubber and extend from a seal around the base of the vent and under several rows of shingles. Sun and weather take a toll on these boots, and they typically will fail after about 5 years. If a boot fails, you will get water under your shingles, and may have roof damage or damage to your ceilings inside your home. If you have a roofer examine the boots every three years, he will be able to replace any faulty one before it causes a problem.

SHINGLES: Shingles, typically made from asphalt, slate, wood, metal or plastic, overlap and are designed to allow water to freely flow off your roof and into the rain gutters. Asphalt shingles, the most commonly used in America, will last between 15 and 20 years. As they weather and age, they will become brittle and begin to crack. That process signals you that it is time to replace the roof. Again, if you have a roofer examine the roof periodically, he will discover when the shingles are too brittle to function well and will need to be replaced.

GUTTERS: The rain gutters are the rain water evacuation system for your roof. Always keep them free-flowing – free of debris, ice and snow. See our blog on G is for Gutter for more information.
