Roofs are complex building components and each roof type and material has its own weak points – here are the most common roof obstructions:
Problems with flat build-up roofs – alligatoring (small cracks on the roof surface caused by prolonged exposure to UV radiation that makes the roof look like alligator skin), roof shrinkage (the pulling away of the topmost membrane from the sides, caused by aging, exposure to heat and UV radiation or improper installation) and the punctures caused by impact, such as hail or sharp stones, twigs and branches falling on the roof are the most common issues encountered on BUR systems;
Ponding water – a universal issue that can affect any type of roof and is usually caused by improper roofing design or the damage sustained by the roof’s support structure that causes roof sections to sag and to allow water to accumulate;
Flashing problems – the stripes of material installed in roof valleys, in the areas where two roof sections meet or around roof openings, such as the chimneys or the skylights, are very sensitive parts that need special attention. Improperly installed flashing stripes or aged, cracked or deformed flashing will let water through, causing leaks and damaging the roof structure. No matter the roofing problem, an expert Dallas roofer can help repair all the above problems, or do a complete replacement.
Texas is a state that has varied geography, each of its geographic regions having its own, very distinct climate. Texas climate varies from humid in the eastern part of the state to subtropical and arid and what makes the state’s climate even more complex is the high occurrence of tornados and other extreme storms on the entire territory of the state.
While such extremes can affect any part of local buildings, the building component that needs to be the strongest and most resistant is the roof, the topmost layer of defense on any construction. The work should be done by professionals experienced in roofing Dallas homes and businesses. The requirement to build roofs that are able to withstand harsh UV radiation, heat, heavy rain, high winds as well as fires has made local builders and building owners turn towards special roofing solutions, such as impact-resistant shingles and special coatings. Impact-resistant shingles have been designed to withstand hail, but they make the best choice for areas affected by other types of extreme weather as well, while the application of coatings on existing roofs is a great way to improve the roof’s resistance to harsh sunshine as well as to the harmful actions of water. Other construction solutions aimed at creating roofs that can withstand Texas weather include reduced slopes – the flatter the roof, the more resistant to the high winds associated with storms.
Each of these options can be better than the others, at the right time.
As long as they can fix the problems, repairs are the most convenient solution. Regular maintenance is critical to detect vulnerabilities and minor problems before they aggravate. Repairs must always be performed very promptly because the more time passes, the greater the damage will become.
Roof restoration consists in a set of operations to make it look brand new and functional again, adding at least another decade to the roof`s lifespan. It is an alternative to roof replacement, being less expensive, more sustainable, providing tax benefits and preventing catastrophic loss. When it comes to repairs, there are only parts of your roof that contractors work on; on the other hand, restoration involves a complete makeover.
However, restoration is effective only if the roof is still structurally sound, otherwise a roof replacement is the only good option.
The replacement of a roof is necessary if the roof is very old and outdated. Old roofs have different problems that may only be fixed partially: most of roofing materials are damaged, there are water leaks, there is no energy efficiency and there may also be structural issues, which are the worst. An honest Dallas roofing company will give you options when they can, but when the roof is old they will tell you it can’t be repaired, it just needs to be replaced.
This is a very popular commercial and industrial roofing option that passed the test of time. It consists in sheets of rubber and other synthetic materials applied on the insulation, to form a protective layer. Besides durability, single-ply membrane provides some other advantages too: considering that it has been used for years, it has a proven track record, it is rated class A when it comes to fire resistance and it can be easily customized to be retentive or reflective, depending on the climate.
Spray Polyurethane Foam
SPF consists in a liquid which is sprayed on a flat roof and expands into foam that creates a resistant protective layer. It is an environmentally-friendly roofing option, which can be used regardless of the climate and which typically lasts for a few decades. Additionally, it provides a high R-value.
Metal roofs for commercial buildings are made from galvanized steel, aluminum or tin. Metal sheets are a lightweight material; it can be installed on an existing roof and also coated for additional protection against rust, water and UV radiation.
