Most commercial roofs are flat or they slope in a very low angle and this feature requires a special approach not only in terms of installation technology, but when it comes to the materials used as well.
Here are some of the most common materials used on flat commercial roofing:
EPDM – the acronym is for ethylene propylene diene monomer denotes an inexpensive, easy to install and very durable rubber membrane. The material is also lightweight and it can be expected to live for at least 20 years;
TPO – thermoplastic olefin is another durable material option used by commercial roof repair Fort Collins pros for commercial roofs, and preferred by the owners of commercial buildings for its affordability, its ability to reflect solar heat and its resistance to corrosion, algae infestations and pests;
PVC – polyvinyl chloride roofs installed by commercial roofing Denver CO pros are usually comprised of two layers, the topmost layer being resistant to UV radiation, moisture penetration, high winds, fire, pests as well as to chemicals;
Spray roofing – these roofs are made spraying polyurethane foam in multiple layers onto the roof decking and applying a topcoat for enhancing the material’s resistance to UV radiation and moisture. The material has superior thermal insulation qualities, therefore it is the preferred solution for roofs in climate zone that get wide temperature variations.
Structural roofing issues are problems that affect the support structure of the roof. They can be caused by a building or design defect, by leaks that have gone undetected and therefore neglected for a long time, by the excessive weight of snow that has spent too long on the roof, by pest attacks and in the most severe cases, they pose very serious safety concerns for the building and for the entire household.
Here are some of the major symptoms of such structural issues:
Roof ridge bending or sagging – a sagging or uneven ridge can be detected from the ground, by simply looking up at the roof; A reputable Colorado Springs roofing company will easily spot structural roofing damage, and provide necessary repairs.
Excessive moisture in the attic – wet beams, rafters and soaked or damp insulation are clear signs that moisture has penetrated through the roof and has soaked into the roof’s support structure, damaging and weakening it;
Signs of structural roof damage inside the house – any deformation or major deterioration of the roof affects the structure of the building underneath as well. Cracked plaster, windows and doors that no longer open and close properly, ceilings that start sagging, cracking or warping, severe leaks that keep recurring are all signs that the roof is affected by unwanted structural changes.
The biggest advantage of a flat roof is the cost effectiveness; installation as well as materials is less expensive than in the case of pitched roofs.
The other significant advantage of having commercial roofers in Denver install a flat rooftop consists in the extra space provided by a flat roof, which can be used for different purposes; you can store air conditioning unit, solar panels or even create a lounge on top of the roof, in the form of a small garden, a barbecue etc. The possibilities are numerous and everything depends on your imagination and preferences.
A roof deck to support traffic is easy to install, not to mention that re-roofing is relatively quick and easy.
Having a flat roof living space installed by commercial roofers in Denver definitely adds discernible value and helps units sell faster, because the building becomes more appealing. The investment itself is not so huge; actually, all you need to have a roof that accommodates people is installing decking, plants and seating.
If you go further and plan an entirely green roof, you must be prepared to pay more money for this. Green roofs cost more to be installed and maintained. The results are truly spectacular and will have a great impact on your life, but you must be ready to invest more money that in creating a simple lounge on top of your roof.
Replacing the roof is a big project that must be planned ahead, with the implication of a specialist able to guide you and help you make the best choices according to the budget you have at your disposal. Replacing a roof, be it residential or commercial, is a long-term investment, but also expensive, that is why you have to be prepared.
The first step is to find a good Colorado Springs roofing company, licensed and insured, who can support their experience with a portfolio and with references from previous clients. It would be a good idea to contact some of these clients, just to find out how their roofing projects went and whether they are happy with the results.
Once you choose a roofing company and receive an estimate, you must identify sources to obtain the necessary money, if you do not have them already.
Finally yet importantly, another thing to think about is the type of roof cover you want. Perhaps one of the reasons why you now change the roof is precisely the questionable quality of the materials used in the first place. So, this time, you might want to focus on other types of materials or at least on a manufacturer whose reputation is impeccable and which provides adequate product warranty.
Most roofing cover materials are designed to last for decades, so if only a few of your shingles or tiles are cracked, you can easily replace the damaged items without having to replace the entire roof. However, be prepared that the color of the recently installed tiles or shingles will not match the color of the rest of the roof perfectly;
The same goes for larger patches as well – you can replace taches of shingles or tiles as well;
Roof sagging – in some cases, the damaged beam that causes the roof to sag can be replaced lifting the roof with an elevator and keeping it up until the new beam is fixed into place, but if more than one beam is damaged, you might want to have a closer look to eliminate the cause of the damage and you might have to replace the entire roof as well;
Other problems that can only be solved with complete replacement – replacement is often the only solution for extensive damage caused by a recent storm and roofs that are very old also need to be removed and replaced.
Investing in a new roof for your business is an operation that raises a lot of question marks about the most appropriate solution. There are many roof types and materials, each with its own pros and cons. Per trustworthy Colorado Springs commercial roofing contractors, one of the options we recommend you to take into consideration is the metal roof.
The advantages of metal roofs:
The first advantage is the variety of materials that can be used to create metal roofs: metal sheets or shingles made from zinc, aluminum, copper or galvanized steel. This variety allows you to choose the most important aspects for you, such as strength, durability, style or costs involved.
Lifespan and strength
A properly installed metal roof will have a very long life span, up to 80 years, comes with warranties between 20 and 50 years and is almost maintenance-free. At the same time, metal roofs provide high resistance to fire, strong winds, moisture and pests. Compared to most other roofing materials, metal sheets and shingles are lightweight. This is an advantage because they are easy to install and do not require a reinforced structure.
The cost of metal roofs is quite high, compared to other materials, but given their long life span, the investment will be absorbed over time.
Using vegetation on roofs is not a modern invention. If in the past the green roofs used to have the purpose of insulating and preventing water infiltrations, now, this option represents an alternative to a less polluting environment, a great protection for roofs situated in areas with many sunny days per year, as well as a way to increase the energy efficiency of a building.
What is a green roof? It is practically a cover of vegetation, placed over an existing roof, waterproofed with a special membrane designed to be resistant to root growth and penetrations, as well as with a drainage system that directs the water to the building’s drainage holes; the draining system also maintains water in places designed to hydrate the soil.
Vegetation on these roofs can grow and develop naturally, without human intervention.
Considering that there are no exposed roof materials, the sun will not damage them. Moreover, a green roof is also naturally soundproof, provides a special look to your home, and maintenance costs are low. Finally yet importantly, it contributes to improving the urban environment, by reducing the temperature as well as the effects of global warming.
Flat roofs vary according to factors like slope and functionality. Flat roofs are not completely flat but they have a very subtle slope of less than 5°. Some of them are designed for higher traffic, others for lower traffic, so they can have slightly different structures.
There are several types of materials used for flat roofs and they must provide good sealing and protection against water infiltrations. Traditionally, flat roofs used to be covered with a mixture of concrete and gravel. However, this option is not very durable because this type of asphalt becomes fragile over time and surface cracks will appear eventually. In addition to not providing long-term protection against moisture, this material is not considered sustainable, because during production and installation, there are chemicals released into the atmosphere.
For new constructions, there are now new types of flat roof materials, such as composite polymer-based liquids. They are much more efficient and create a membrane that practically seals the roof.
According to Fort Collins commercial roofing flat roof experts, being a relatively easy and low-cost option, any type of flat roof offers protection as well as multiple possibilities for using its space, which makes it a good choice, especially when it comes to modern, minimalist, cubist style or commercial buildings.
Folded plate roofs are roofing systems chosen for their high weight-bearing capacity and their durability. They can be best described as assemblies that consist of flat slabs or plates that are inclined in different directions and are joined along their edges at the top.
The first folded plate roofs were used in Germany in the 1920’s, mainly for very large factory buildings such as coal bunkers. The technology was first used in the U.S. in the 1930’s on warehouses and it quickly became the preferred roofing solution for really large commercial and industrial buildings.
Lightweight systems – metal roofs are resilient without being heavy, therefore they are suitable for any building, very solid and lightweight construction alike;
Low maintenance – metal roofs also need to be regularly inspected for minor issues, but the metal panels used for making the system are made from special alloys that are resistant to corrosion, to rust and to other forms of damage, so you will probably not need to do any major repairs on your roof;
Durability – the estimated lifetime of metal roofs is between 30-50 years;
Fire resistance – metal does not catch fire, therefore metal roofs can be used on buildings that pose a fire hazard from the inside or are located in dry and fire-prone areas;
Energy-efficiency – metal roofs form very efficient thermal barriers that enhance the energy-efficiency of the entire building, keeping the temperature more even in the building the year around.
