There are a few factors including roofing material and weather that
could effect longevity and help the homeowner determine when to make any
necessary repairs. Depending on the material, the life of a roof can be
anywhere from 15 to 50 years; however the average life is about 20
years.
A leaky roof is not the only sign that it needs to be replaced. However,
waiting until there are noticeable water leaks might be too late. There
are a few factors including roofing material and weather that could
effect longevity, and help the homeowner determine when to make any
necessary repairs.
Depending on the material, the life of a roof can be anywhere from 15 to
50 years; however the average life is about 20 years. Many different
materials including wood, metal, or ceramic can be used for roofing.
However, they are the least common because they are less durable and
more expensive than the more common options. Asphalt is the most common
material used today. It is widely used because it is a great value. Most
manufacturers can make the shingles in a wide variety of colors and
patterns, and will guarantee them for up to 30 years. Architectural
shingles are an upgrade to the asphalt and have gained popularity over
the last few years because they are heavier and more weather-resistant.
This material is designed to last for at least 40 years, although some
manufacturers will give them a lifetime guarantee. Slate is the most
durable of these options, although it is more expensive, and therefore
less common; this material is typically guaranteed for up to 50 years.
Durability is the most important factor for choosing a roofing material.
Roofing materials are made to withstand weather conditions in order to
protect the home's interior. Accelerated wear can be expected in areas
with extreme weather conditions. Heavy snow can cause a roof to cave in,
while strong wind can cause the shingles to tear off and leave parts
exposed to the elements. Homeowner’s living in these areas should be
conscious of weather patterns which can cause damage, making small
repairs early can prevent the need for a complete replacement later.
Slate tends to withstand some of these extreme weather conditions better
than any other material because it sheds ice and snow. Furthermore,
contractors will use different techniques and adhesives to replace the
roof, which can have some effects on its longevity.
Proper roofing on a home has a number of advantages besides just
protecting the home from poor weather conditions. Homeowner's can save
thousands on their energy bills when the home is properly insulated, and
some older homes might be due for an upgrade in order to patch areas
where heat or cool air might escape. Knowing when to replace the roof
can save thousands because the it is protecting what is inside the home.
