With any type of roofing, it goes without saying that if there is water leakage permeating the outer barrier of your roof then you've got a big problem on your hands. This is a two-fold issue. In the short term, it's a matter of having to deal with water getting into your home, office or business and damaging your furniture, electronics or equipment. In the long term, you can have mold problems.
The long term consequences caused by water leaking through the roof only can range from a structural problem, all the way to much more dangerous issues such as safety and health risks.
The first and most obvious is the possibility of getting items stored in your attic area damaged. In the case of having no attic, the interior celing will immediately be affected.
Mold and mildew are the most serious dangers to your life and health of all, and spread all throughout the home's structure and HVAC system before moving on the your carpets and upholstered furniture. After gaining a strong foothold, it can even invade your clothes.
Water getting into your home or office can also create fire hazards by shorting wires. If you notice water leaking near parts of an electrical system, it's best to flip off the breaker in the affected area.
Another hazard stems from the possibility of slipping and falling on the puddled water. An increase in your utility can also be seen as the water slowly erodes the insulation in your attic.
The average lifespan of each type of material used in roofing can depend, and is ultimately one of the reasons that we must be so deliberate when choosing what to install on a building, whether residential or commercial.
Asphalt 3-tab shingles are by far the most common material covering roofs today. They have one of the lowest life expectancy of all, which is from 15 to 18 years on average. The lowest of all is EPDM or rubber roofing, which last anywhere from 10 to 16 years. Modified Bitumen and Built-Up roofs weigh in about the same.
Moving on up, we have the architectural type of asphalt shingles, which tend to have a life expectancy of anywhere from 24 to 30 years on average.
Metal roofs are not only some of the most affordable of all, they also have a pretty good life expectancy. Also called Galvalume, they can last anywhere from 30 to 45 years.
Concrete Tile shingles are one of the more attractive types of roofing material, and last anywhere from 35 to 50 years.
There are also other factors that can influence your roof's longevity, including the color, direction it is facing, and angle of slope.
