Many times, when a person needs a new roof they have two things in mind: the price and the color. However, it is equally as important to consider the type of weather where you live and what material would best suit the situation.
Heavy winds are especially bad on a roof when light asphalt shingles are used. Actual high wind resistance also involves the method of installation. In order to receive the most wind resistance on a roof, it is important that the entire assembly is geared toward this purpose. This begins with the structural deck and includes the insulation/board layers, the membrane and the surface covering. Flat roofs are often the best in this kind of situation as long as they are insulated properly with an EPDM or TPO membrane and there typically isn’t large amounts of precipitation to create ponding.
If you live in a high wind area always check the specifications of the roofing materials you choose as well as the manufacturer and installation warranties. While lightweight asphalt shingles are cheaper, they usually need costly repairs when exposed to this type of weather. More durable, quality shingles are able to withstand these harsh winds, especially when installed and secured properly by roofing professionals. Another option would be metal roofing as they are much less moving parts and as long as they are installed properly by a professional, are much more resilient in windy conditions.
Each year finds various parts of the country exposed to snow. This may be a heavy load of snow that stays on the roof for a very long period of time or just a small amount that melts off quickly. If the roof slope is low, metal roofing is preferred as it makes the snow easier to handle. They typically allow for snow and water shedding due to their material and help prevent and protect against water ponding and damage. With steeped sloped roofs, roughly textured roofing is preferred as it holds the snow in place rather than allowing it to slide off and injure someone.
It is extremely important that proper insulation and roof ventilation be in place with such a roof. This will minimize the formation of an ice dam. It is also possible to install snow melt systems, or heat tape, to minimize ice accumulating in valleys or on eaves. Regardless of they type of roof chosen for snowy areas, it is important to have plans in place to prevent snow from lingering and staying on top of your roof to prevent damage. Whether the roof is designed to shed the snow naturally or it requires a more manual approach, its a good idea to have a snow removal professional take a look as soon as possible after extreme snow storms or even when you see or notice that the snow isn’t budging.
Many parts of the country are exposed to extreme UV sun exposure during the summer months. This can cause high energy bills, which makes it well worth a good roof to avoid this expense. In addition, extreme heat can cause extensive damage to the roof materials. Both metal roofs and shingles with acrylic coatings are ideal candidates in these environments as they help to reflect UV rays away form the house and keep the inside cooler.
Thermal shock is another name for fluctuation of temperatures from hot to cold when day and night temperatures vary greatly. Your roofing system contracts and expands as these temperatures change. Older roofs are often unable to survive this kind of treatment. If you live in this area of the country always check with your roofer regarding the type of roofing that will best fit your requirements.
Rain and Hail
While rain is something the entire country needs, in some areas it seems like it will never stop. Choosing roofing materials that have a track record of water repellent quality is extremely important when living in this weather-related area. Proper installation of gutters is also essential as they help move the water buildup away from your roof and home to prevent ponding and buildup.
Hail can not only be noisy but cause extensive damage. As a rule, hail stones smaller than half-inch around will not do extensive roof damage. If it is larger than that, it is important to have your roofing contractor make an examination when the following signs appear:
- Loose Asphalt Granules
Large sized hail can cause the asphalt granules to tear loose and wind up in your gutter. Wood shingles usually show damage with wooden splinters or shards. Either of these cases can result in immediate leaks into the roof’s under-structure.
- Missing/Broken Shingles
During a storm, any old shingles can become loose and/or completely removed from the roof. This is because, over time, they will lose their adhesive and become brittle. Always inspect your roof after a storm. This will help avoid damage to the contents underneath.
The importance of your roof cannot be over-emphasized. It is what protects the building’s contents as well as its occupants. Having a regular roof inspection program will assure that you receive the very best benefits your roof has to offer.
