According to the statistics prepared by professional associations, the average lifespan of roofs in Texas for all roofing materials combined in 18-20 years. However, that figure can be quite misleading as the durability of individual roofs is determined by a very wide range of important factors – here are some.
The Roofing Material Used
Each type of roofing material is warranted for a specific period of time:
- Asphalt shingle roofs are warranted for about 20 years, but their longevity will also depend on the thickness and type of the shingles, on the extreme weather events that the roof is exposed to and whether the shingle roof is the first or the second layer of material installed (asphalt shingles can be installed on the old layer of roofing material provided that the building is able to support the extra load);
- Metal roofs can stay on the roof for about 40 years;
- Built-up roofs – BUR structures are great for flat roofs in Texas, offering proper protection for over two decades;
- Spray-foam roofs – another great solution for flat roofs, sprayed roofs can last for around 30 years;
- Clay and cement tiles – these two materials can stay on the roof for about a century, but they are quite heavy, so not all lightweight buildings can support the weight of the material;
- Slate – the most durable roofing material of them all can outlast the building itself, but load-related aspects need to be taken into consideration, just like in the case of tiles.
The Quality of the Installation
The above figures are for roofs that have been installed correctly, so when you choose your new roofing material, choose professional and licensed roofing contractors in Houston TX to install it for you as well.
The Quality of the Maintenance
A good durable roof is one that is not only installed properly – it is one that is maintained regularly as well. Whatever material your roof is made from, regular cleaning, inspection and the timely repair of the issues identified during the inspection are essential for being able to have a roof that lasts for the period it is warranted for.
Ideally, roofing maintenance is performed twice a year, once in spring, to tackle the damage caused by the colder months and once at the end of fall, to remedy whatever harm the harsh summer has caused and to prepare the roof for the winter. The procedure should be extended to the areas around the roof openings, such as the skylights and the chimneys, to the vents, the gutters, the downspouts and the attic as well.
Trees are great assets on any property, but the large trees that have branches and limbs overhanging your roof can pose potential hazards. To prevent any damage caused by fallen branches, make sure to inspect your overhanging trees whenever you inspect your roof and cut off any branches that seem old or weak.
Texas is frequently affected by extreme weather. Unfortunately, the roof damage caused by hurricanes, tornadoes or hail cannot be entirely prevented, but a well-maintained roof, made from the right material and installed properly can stand up to whatever weather comes along much better than a weak, leaky, neglected roof.
