How to Get Rid of Mold Before It Does Any Damage to Your Commercial Roof

commercial roofers in Denver

Mold can easily damage the interior of your home and cause a lot of health risks that most people don’t even want to look at. However, it’s equally important to guard against mold developing on the exterior of your home or building, especially considering the best ways to spot and get rid of mold on your roof, before it causes too much damage:

  1. Work together with your commercial roofers in Denver to establish and use proper maintenance tasks that are adapted to the type of roof you own. While some roofing systems can be left without any cleaning or maintenance for up to a year, others require more care and consideration, as certain stressors – such as temperature differences, hail or snow – can damage them more easily and lead to the faster production of mold when the temperature and humidity levels end up rising.
  2. Learn how to distinguish between the main types of mold, and use testing kits to determine whether mold is growing in specific areas of your roof. It also helps to read up on the roofing material your roof was made from, and check to see if it has more of a propensity to develop a certain type of mold.
  3. Spot mold early and remove it using professional equipment or by hiring an expert to do it for you. If you’re not sure how to remove certain types of mold efficiently, always call on your local roofers to help you out and refer you to a specialized service for the job.

What Are BUR Roofing Systems and What Are Their Main Advantages?

If you know a little bit about flat roofing systems, you probably heard or read about the abbreviation “BUR.” BUR roofing (which is short for built-up roofing) is one of the most common types of roofing systems used by commercial roofers in Denver when installing low-slope and flat roofs. This type of roofing is made from alternating layers of bitumen (asphalt) and various reinforcing materials designed to promote durability and long term resilience.

The great thing about using this type of roof on a low slope or flat roof is that it creates a virtually permanent seal. Unlike in the case of higher slopes, where the construction has to be adapted to the slope to generate an appropriate seal, and flashing has to be used to enhance and consolidate the seal to prevent any leaks, bitumen and BUR roofing systems don’t need any of that. The various layers press upon each other, and modern day BUR systems also use an additional, highly resilient insulation layer that enhances their energy efficiency.

Basically speaking, if you’re looking for a low slope roofing design that will withstand strong impacts, water damage, fires and large temperature fluctuations, BUR roofs would be considered one of your best choices by far. Just contact your local commercial Denver roofing experts, and they can tell you precisely how to make sure you get the best value for your money.

Guide to Commercial Roof Insulation

The financial success of a company highly depends on the quality of your roof insulation. At the same time, it is required by the current legislation. For these reasons, it is essential to understand the importance of making the right choices for your commercial building insulating systems.

There is a variety of materials that can be used for insulating a commercial roofing system. The most versatile material in this respect is EPS (expanded polystyrene). This insulating material does not retain water in the long run and keeps insects away. It does not deteriorate over time, so it can be used for long periods of time. To make sure your roofing system is insulated properly and operating at it’s best capacity, schedule time to talk to the best commercial roofers Denver has available.

XPS or extruded polystyrene usually comes in pink, blue or green. It is not a vapor barrier, but rather a vapor retarder and it is recyclable. Polyiso (polyisocyanurate) is the most common type of insulation material. It is not recyclable, but it is quite resistant.

Concrete is a very common material, which provides good insulation and does not get damaged too soon. It does not rot or get neutralized in case of humidity.

The exact type of insulation that your commercial building needs depends on several factors, such as the age of the building, the budget you have at your disposal, or local legislation.

Flat Roofing Materials

Flat roofs are nowadays a popular choice and not just on commercial facilities, but also on residential buildings. This is mainly due to their great performance (materials have been constantly improved along the years) and aspect that compliments modern, geometrical homes.

The traditional BUR roofing is now stale, because there are other materials designed to greatly increase the reliability of a flat roof.

According to recognized commercial roofers in Denver, there are 3 basic types of flat roofing materials. Read on and learn some essential information about them.

Single-layer membrane

A flat roof covered with a single-layer membrane (known as elastomeric membrane) represents the latest technology in terms of flat roofing and is very popular in commercial construction. Popular and efficient PVC and EPDM are varieties of single-ply roofs.

Modified bitumen

This roofing type has been developed more than 5 years ago, as a replacement for built-up roofing technology, by adding roof wear layers reinforced with polymers to improve elasticity in low temperatures. Installation methods for modified bitumen include hot or torch applied, cold applied, or self-adhered.

Built Up Roofing

We can say that BUR is the grandfather of flat roofs, being a very old technology, installed using layers of a special felt impregnated with asphalt, embedded in bitumen and applied with a hot mop.


Flat Roof Maintenance Tips

A flat roof requires special maintenance operations to remain in good shape for as long as possible, fulfilling its role to protect the building. Regular maintenance ensures that there are no vulnerabilities and problems that could escalate into disasters. It does not cost much, not even when you call for specialists, but will help you save significant amounts of money for repairs or for a premature roof replacement.

Here is a little guide on how to maintain a flat roof.

  1. Make a regular maintenance schedule. In order to be efficient, maintenance has to be periodic. Ideally, a flat roof has to go through this process every 6 months, or whenever a severe weather phenomenon occurs.
  2. Always call reliable commercial roofers Denver contractors to inspect the roof`s membrane. Even if you prefer to deal on your own with other maintenance operations (such as cleaning the roof for example), the inspection and repairs should be performed by a specialist who is trained to identify any potential problems and formulate the best course of action to repair them.
  3. A flat roof should be cleaned periodically. Because of its shape, twigs, leaves and dirt tend to accumulate on it and block the drainage system, which is something that must be prevented. Draining holes of a flat roof must also be checked during the regular maintenance and unclogged if necessary.
  4. The surrounding trees must be trimmed so that there is no risk of braches falling on the roof during a storm.

Creating a Rooftop Terrace for Your Business

Creating a green terrace on the roof has become possible for anyone who has a flat roofed building. Any flat roof on the top floor of an office building can become a place of relaxation and socialization, because it can be transformed into a beautiful green garden, with spectacular plants, flowers, shrubs and even trees.

Contrary to the opinion of many, the construction of a green terrace on the roof is not a complicated process, and the benefits make the investment profitable.

Insulating the roof to make it able to sustain a green terrace is easy nowadays, considering the wide variety of materials and coatings that seal the roof and make it completely waterproof. New roofs installed by quality commercial roofers in Denver, are actually designed to be waterproof, regardless of whether the space they provide is used as a terrace or not.

Heat losses at this level are important, and infiltrations through poor quality membranes can compromise the work of those who have endeavored to complete a solid construction and the related finishes. Therefore, the quality of the materials and the execution must be beyond any suspicion. A green roof terrace does what any thermo-waterproofing system does and, with a small amount of resources, it can bring life back to an apparently compromised landscape, because nature always finds resources to regenerate.

Signs That Your Flat Roof Was Hit by Hail

Some forms of hail damage are obvious, others are hidden and difficult to detect, but all of them can aggravate very quickly, so it is essential to find and fix them very soon after the hail-storm that caused them. Here are some of the most common signs that indicate hail damage:

  • Dents on the gutters – the gutters are usually made from material that is weaker than the material of the roof surface, so if the roof has suffered any hail damage, the gutters will be dented;
  • Damaged vents – look for dings and dents there as well;
  • Chimney covers – most covers are also made from metal, so the damage caused by hail is the same as in the case of the vents and the gutters;
  • The roof covering – the signs of hail damage differ depending on the material. Metal roofs show the same signs as the other metal components, foam surfaces get holes or form gaps, while PVC can get cracks. Gravel roofs are the most resistant to hail, the impact caused by the ice balls hardly affects them, but the special construction of these roofs makes damage difficult to find, so the best way to diagnose your roof is to hire specialized hail damage commercial roofers in Denver for the job.

The Dangers of Ponding Water on your Flat Roof

Flat roofs have a very slight inclination, invisible to the eye, that’s why heavy rains can form ponds on their surface. This is not a reason of concern unless water remains on the roof for more than 48 hours.

The flat roofs are designed to resist water ponding, being covered with sealing membranes and provided with water drainage systems. However, ponding water is always a risk and must be avoided to protect the roof. Flat roof commercial roofers in Denver are experts in this area, and can be called upon for inspections, repairs, and all other roofing services.

First, standing water adds weight on the roof and increases the pressure on its structure. It weighs about 5 lbs. per inch, so a large ponding area can stress the roof more than you may realize. Also, as water accumulates, it tends to cause deck deflections (sags), which will gradually increase the ponding water problem, compromising the structural integrity of the decking.

Ponding water also cause premature wear because it attracts algae formation and dirt, so the roof`s membrane is more prone to rot.

The building owner must address this problem promptly, not just because of the risks, but also because most roof warranties are voided if the water ponds for more than 48 hours. A flat roof must be carefully inspected after each rain storm.


Tips for Staying on a Commercial Roof Maintenance Schedule

Running a Denver business involves lots of tasks to see to, including not only the tasks related to the business itself, but to the building that the business is run from as well – no business can be safe if the building it resides in is neglected and this is especially true for the roof. The most important task to handle if you are to make sure that your roof will function properly for its entire lifetime is roof maintenance, so here are a few things you should know about how to schedule roof maintenance tasks:

The process should involve detailed inspection, roof cleaning and the repair of any issues found on the roof;
  • Maintenance of the draining system – if your commercial roof is flat, you need to pay special attention to its drainage needs. Water tends to accumulate on the surface of flat roofs and without proper drainage, ponding water can and will damage your roofing surface, so make sure that the gutters and the drainage spouts of your roofs are inspected and cleaned during the six-monthly maintenance or, even better, after each big storm.
