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.

Signs of Commercial Roofing Problems and the Importance of Roof Maintenance and Repair | Commercial Roofing in San Antonio TX

Jamie Ndungu - Sunday, April 15, 2018


The roof of your commercial building is the first line of defense in case of seismic disasters such as hail, ice, snow, fire, rain, heavy winds, storms, heat, etc. The roof, on the other hand, is also very vulnerable. It is exposed to different weather conditions at all times, every day, and certain elements may contribute to its deterioration. Not to mention deteriorated roofs pose the contents of the building to a high risk of damage.

The authority that sets safety standards for commercial buildings, called the International Building Code (IBC), has set a requirement for the roofs of commercial buildings to “serve to protect the building.”

This and other safety reasons are the force that compels people to call professionals such as Longhorn Commercial Roofing in San Antonio, TX. A roof’s strength does not only depend on the materials used to construct it and appropriate installation but also on the design of it. A roof that “protects the building” is built considering all of these things to ensure safety and the business’s continued operation in case of a disaster.

Apart from the construction requirements, you need to ensure schedule regular programs of inspection, maintenance, and repair in order to increase the useful life of your roof and ascertain that it does what it is meant to do.

Here are the common signs of problems related to commercial roofing in San Antonio, TX and everything else you need to know about roof care.

Recognizing the Signs of a Roof Problem

As a business owner or a commercial building owner, it is your responsibility to keep a check of the problems your roof might be facing. If it is been a while already since you last checked your roof for any issues, it should be your foremost priority to hire a professional for commercial roofing in San Antonio, TX to identify and fix any existing and potential problems.

If the roof is facing a serious problem, the signs are often evident from inside the building as well. For example, water stains on the top surface of the premises may indicate a leak caused by a crack or hole in the roof.

Remember, no leak is negligible or less important from the other, even if it is a small leak. Even the smallest leak you see can easily put you in shambles by expanding over time. Likewise, if your commercial building has molds or bad odor inside it, this may be a sign of water penetration because of roof leakage. It’s important to understand that even the smallest leak can be a sign of big trouble.

While these few signs observed from inside the building are sufficient for you to call a professional for commercial roofing in San Antonio, TX, it is more important to physically inspect your roof yourself to see if any problems are evident and keep them from worsening.

While business owners or other people working in a building should regularly check for roofing problems in a commercial building, this is not enough. There may be underlying/hidden problems that only a professional for commercial roofing in San Antonio, TX will be able to identify and resolve. For this reason and more, it is a smart choice to hire a contractor to ensure safety as well as to prevent and/or fix the potential/existing problems and their recurrence.

Looking for the Visual Clues on the Roof


  • Ponding on the roof or water that is standing for long can result in premature aging and destruction of the cover of the roof and ultimately cause huge leaks. Leaks that are left untreated deliberately or are unnoticed for awhile can steadily result in the rusting, rotting, and deterioration of insulated concrete and gypsum decks, which turn into a thick paste. Furthermore, the water standing on the roof can put additional pressure on it due to the weight, which then weakens the deck of the roof.
  • If you see bubbles on your roof, this is probably a sign of trapped moisture inside the cover of the roof, which can soon cause leaks. Trapped moisture can also drastically reduce the durability of the roof, accelerate premature aging, and reduce the effectiveness of the roof’s cover system against forces such as winds.The release of gases trapped below the cover from the insulation board could be another source of bubble formation on your roof. A moisture survey done by an expert dealing in commercial roofing in San Antonio, TX will help diagnose such issues easily.
  • Waterproof material or metal strips that are fixed along the roof is called roof flashing. It is also draped around other roofing equipment to deflect water away from the seams and joints. When a gap emerges in the flashing or roof cover perimeter, it increases the risk for roof failure during an event that leads to water intrusion or brings in high winds and molds.
  • Cracking, worn seams, or tears in the roof cover can also make a way for water to enter below the cover and cause problems.

Hiring a Professional for Roof Care and Maintenance


  • Choosing a provider who is established, licensed, and/or has bonded professionals.
  • Obtaining estimates before the work has started.
  • Checking if the provider and his technicians are insured. If possible, ascertain that the coverage for liability and workers’ compensation insurance is up-to-date.
  • Checking website ratings or contacting your local Better Business Bureau to know about any complaints filed against the provider.
  • Discussing and verifying your warranty and guarantee options. Confirming what is or isn’t covered and asking any questions you need to be clear.

A roof that is properly maintained and strong is imperative to safeguard your building, business, and the people associated with it. A little amount of money spent on roof maintenance goes a long way. Dial 210-446-3982 to connect with the experts at Longhorn Commercial Roofing in San Antonio, TX.






Commercial Roofing in San Antonio, TX – Maintenance

Jamie Ndungu - Thursday, March 15, 2018

In the past, we have spoken quite a bit about how important it is to have your facility's roof inspected and by having periodic maintenance and other vital repairs performed before the colder weather sets in. Today we will talk about just how damaging natural debris can be to a roofing system. Such as in the fall, when all of those gorgeous orange, gold and brown autumn leaves begin falling from the trees and how they can cause damage to a facilities commercial roofing in San Antonio, TX.


With a little bit of moisture and a heap of feathery light leaves, it can create a soggy, heavy biodegradable heap that can clog drains and create the perfect scenario for the proliferation of fungi, mildew and mold. If it is not promptly addressed, leaves and the debris can lead to water backing up which will increase the load on the deck of the roof. Standing water, just an inch in depth, adds around five pounds per square foot on a roof assembly. Over time, that standing water can leach the pliable properties out of some single-ply membranes which will reduce the flexibility and the life cycle of the roofing system.

In the winter months, ponding becomes a very critical scenario when pooling water begins to freeze and expand which causes it to force its way into tiny cracks or under the roofs flashings. Additionally, any additional ice weight can cause structural damage and expensive repairs and in worst case scenarios it can even cause a roofing system to collapse.

Preventative Maintenance

Maintenance crews that handle the commercial roofing in San Antonio, TX should be trained to inspect for leaves and other debris around the drains. During the fall months before winter sets in, frequent inspections should be done in order to remove the debris in order to help prevent the possibility of buildup and blockage. Areas where there are standing water could possibly indicate blocked drains and they should be addressed immediately. Partially blocked drains will still allow water to flow slowly, so even if there is no standing water on the roof it does not indicate that there is not a problem with the drains and they should still be inspected for debris. If there is noticeable staining on the roof, this could indicate that there were previous ponding. Not every problem that is caused by falling leaves and other debris will be visible to the untrained eye and it is critical to have a qualified roofing professional such as Longhorn inspect the roofing system for you. Drains and gutters should always be cleared before frigid temperatures kick in and turn a soggy leafy mess into frozen blockages.

Additionally, after the disposal of falling leaves and debris, a qualified roofing specialist should water-test both the internal and external drains and inspect the gutters and downspouts. The roofing specialist will inspect the little things that could escape the notice of a maintenance crew, such as inspecting the strainers to make sure that they are tightly in place and that the bolts securing them are tight also. It will take an experienced and trained eye in order to recognize early problems with sealants, flashings, mortar, seams and penetrations. Gutters and downspouts should also be inspected for the possibility of sagging, loose connections and also for broken or missing fasteners.
