The asphalt shingle roof is the most popular type of roofing in the United States. The average lifespan is up to 20 years. The materials start at prices below a dollar a square foot, are easy to install and simple to repair. If your shingle roof is aging, we offer a seamless, durable elastomeric coating to seal shingles against leaks and damage.

Metal standing seam roofs are factory-made panels with raised seams that interlock then are sealed watertight. It has been used in half of all low-rise commercial and industrial buildings constructed in the last several years.

Modified bitumen is ideal for buildings with flat or low slope roofs. It is manufactured in rolls with adhesive on the underside to bond the roofing to the substrate.

Metal roofing complements home exterior decor, delivers the long-lasting affordability commercial structures require, and is the first choice for industrial building. In light colors, or with a metal roof coating, the energy efficiency is significant.

Roof coatings adhere to many kinds of roofing materials. The products are not “one size fits all,” but are engineered for specific roofing materials. What they do have in common is exceptional “reflectivity,” which means heat from the sun bounces away from the surface, significantly reducing air conditioning costs.

Elastomeric roof coatings are applied as a liquid, and then dry to a seamless coating that prolongs the life of your roof. It is an economical roofing solution for BUR, modified bitumen, metal, cement, and EPDM roofs.

For rubber roofs, a seamless coating results in years of worry free and maintenance free service. An aging EPDM roof shrinks and cracks. The coating restores leak protection.

Metal roof coatings are the innovative solution for commercial, industrial, farm and ranch structures. Your roof is coated with layers of polymer leak and rust protection.

Flat roof coatings eliminate the succession of troubles associated with flat roofs such as chronic leaking, ponding and rapid deterioration. Ask about it if your current roof is hot-tar modified bitumen rubber; built-up single-ply metal; or polyurethane foam.

Matt Parker - Sunday, October 15, 2017

Longhorn commercial roofing in San Antonio, TX offers a number of roofing options for your business. When your roofing project is on a tight budget, single-ply roofing is a option for building owners in need of a proven, cost-effective roofing system. There are a lot of factors that account for the popularity of single-ply, including the following. Single-Ply Roofing | Longhorn Commercial Roofing San Antonio, TX

The Benefits of Single-Ply Roofing

  • The manufacturing method and strict quality control of single-ply provides a roofing material of consistent quality.
  • Single-ply roofing offers a cost effective solution for your roofing project, and is effective for a low-slope or flat roof. Not all roofing materials can make this claim. Longhorn commercial roofing in San Antonio, TX can assist you in selecting the best roof for your building and budget.
  • Single-ply resists deterioration resulting from the sun's UV rays, with white roofing providing the greatest resistance. In addition, white is the most effective option in reducing the roof and attic temperature in hot climates. As a result, you can also see a reduced temperature in the building's interior. These benefits provide your business with energy savings, and the reduced need for the air conditioner to run as often. Consequently repair bills on the AC are averted with reduced wear and tear, saving you even more money on expenses.
  • Longhorn commercial roofing in San Antonio, TX installs single-ply roofing are on new buildings and existing buildings. Furthermore, the product can often be installed on an existing roof. Your roofing contractor can determine if your situation will allow a roof-over with single-ply.
  • White, and other select light colors of single-ply roofing can provide points for your building's LEEDS certification.
  • Single-ply roofing provides fire resistance, and resists the adverse effects of chemicals and pollution.
  • The seams of many types of single-ply roofing are heat welded to form an extremely strong bond. After welding, a specialized coating is applied to the seams for supplemental waterproof protection of the seams. The result provides superior leak protection for your building.
  • Single-ply roofing systems offer a strong, flexible and durable roof for your commercial building. Contact Longhorn commercial roofing in San Antonio, TX for additional information.

    The Disadvantages

    A thicker gauge material provides greater tolerance against foot traffic, hail events and punctures. When single-ply is chosen for a roof with foot traffic, you should take precautions to ensure punctures do not occur. Always inspect any roof for damage after hail events or storms.

    The Types of Single-ply Roofing

    Single-ply roofing is available in three types: thermoset, thermoplastic, and modified bitumen. You can rely on the quality of craftsmanship and the product when you contact Longhorn commercial roofing in San Antonio, TX.

    Thermoset roofing is formed of rubber polymers, and therefore the seams can not be hot air welded. Instead, the seam is formed with specialized tape or contact cement. EPDM is a type of thermoset roofing, best known for its flexibility, resistance to weathering, and its tolerance of UV rays. It is available in sizes up to 100 feet, and as thick as 90 mils in both un-reinforced or reinforced types. For obvious reasons, it is especially advantageous for large roof areas and minimizes the number of seams necessary.

    Thermoplastic roofing is a plastic polymer with plasticizers added to provide flexibility. PVC (polyvinyl chloride) is an one type of thermoplastic. Hot air or chemical welding is used to form the seams, and when complete are as strong as the membrane itself. Thermoplastic membranes are often reinforced with polyester or fiberglass. PVC is naturally fire retardant.

    TPO is another type of thermoplastic, and can be installed in a number of ways. One popular version is a peel-and-stick product that significantly reduces the installation time. In addition, TPO can be hot-air welded at any time during its life span, a bonus for repair and maintenance of your building.

    Modified bitumen use prefabricated layers of asphalt, with the addition of plasticizers to provide flexibility, and includes a layer of reinforcement for additional strength and stability. It provides the advantages of EDPM, TPO and PVC , while offering a number of surface finishes and multi-ply configurations for added strength. Longhorn commercial roofing in San Antonio, TX will be glad to provide you with additional information.

    Making a Selection

    The factors to be considered in your roofing choice includes budget, building height, wind exposure, estimated foot traffic, the desired appearance, and the attachment system. The roof slope, height, location and whether or not high winds may be a problem are some of the factors determining the attachment system used. Longhorn commercial roofing in San Antonio, TX can provide you with the information you require, ensuring you can make an informed choice.

    Installation and Maintenance

    The use of a skilled and qualified roofing contractor, providing routine maintenance and roof inspections are key factors in attaining the expected life span of your commercial roof. Inspection after storms are not the only time to inspect the roof, you should also ensure no damage has occurred after workers have been on the roof.

    Common Roof Issues

    Eventually any roof will have problems that require repair, or replacement. Ignoring the need for repair, aging roofs, weathering and a lack of maintenance are all factors that are detrimental to commercial roofing. The following information is the indications of a roof in need of professional attention. Contact Longhorn Commercial Roofing in San Antonio, TX today for all your roofing concerns.Longhorn Commercial Roofing San Antonio, TX

    Crazing is the development of fine cracks on single-ply membrane, and if not addressed will lead to roof failure and leaks. Roof coatings offer a solution for crazing. Contact Longhorn Commercial Roofing in San Antonio, TX for additional information.

    Seam failure can occur due to several possible causes. Shrinkage and the loss of elasticity over time, along with age and weathering can degrade the seams, leading to failure and roof leaks. Routine inspection and maintenance are essential, along with prompt repair when seam failure occurs. Seam failure may also occur when a roofer provides poor craftsmanship in its installation.

    It is common for roof leaks to occur around flashing that has come loose, has lost its seal, or has been damaged. Flashing is installed around the roof perimeter and intrusions through the roof such as pipes. To prevent structural damage to your building from leaks, contact Longhorn commercial roofing in San Antonio, TX.

    Metal Roofing is one of the best investments for a qualifying commercial business. It can potentially last indefinitely with the proper care. Metal roofing requires very little maintenance for many decades. Routine inspection and an annual cleaning are the best tools for ensuring your metal roof lasts a lifetime, or even longer. Eventually, typically decades later, the protective coating, paint or galvanizing wears off, allowing rust to set in. The rust can be removed, and the affected areas treated with rust inhibitor, followed by painting for a protected, and like new finish. Contact Longhorn commercial roofing in San Antonio, TX when your metal roof needs repair and/or refinishing.

    Smooth surface asphalt roofs can develop a cracking of the surface called alligatoring. The process of the asphalt drying out is due to the sun, and can extend completely through the roof surface, allowing leaks and damage to occur. If your asphalt roof is developing alligatoring, contact Longhorn commercial roofing in San Antonio, TX for a solution.

    Flat or low sloped roofing can experience ponding, where water stands on the roof. Ponding not only accelerates roof deterioration, it is the source of fungi and vegetation growth, sediment deposition, and eventually leaks. Due to the weight of accumulating water, over time the areas experiencing ponding will increase in size. As the areas and weight grow, collapse of the roof structure can occur. If your roof is experiencing ponding, prompt repair is essential. Contact Longhorn commercial roofing in San Antonio, TX for reliable repair.

    Mold thrives where moisture is present, such as occurs due to roof leaks, or gutter failure. Blocked gutters can cause water to back up and can result in both structural and foundation damage to your commercial building. Periodic gutter inspection can prevent gutter backup,while roof repair for leaks will prevent additional damage.

    Blistering occurs when moisture is trapped within the membrane plies. As the outdoor temperature increases, vapor from the trapped moisture expands, forming a blister on the membrane. A blister weakens the membrane and results in roof failure if repair is not provided.

    Emergency Roofing Services

    Always inspect your commercial roof and its drains after storm, high wind and hail events. If wind blown debris is present go ahead and remove it to prevent additional potential damage, and/or the development of mold. If your building's roof has been damaged, contact Longhorn commercial roofing in San Antonio, TX for emergency roof repair. Repairing a damaged roof promptly can mean the difference in effecting a repair, or the need for roof replacement if you should delay repair.


    • Trim overhanging tree branches to prevent damage from rubbing. In addition, eliminating overhanging branches can help to reduce leaf debris and related problems with moisture.
    • Keep the roof clean and free of debris and loose objects.
    • Keep the gutters free of leaves, bird nests and other materials. Inspect them routinely for damage. Replace damaged gutters.
    • Be sure to check the seals around vent pipes, HVAC system or other equipment on the roof. In addition, do not forget to inspect fasteners for loosening and the edges of the roof system for damage or loosening of membranes.
