Commercial roofing types advantages and disadvantages they provide Part 4:
Commercial Metal Retrofit Roofing: Pros & Cons
Metal retrofit roofing is a simple, cost-effective method of re-roofing your older, end-of-life metal roof with a durable membrane.

Advantages of Metal Retrofit Roofs
The biggest advantage is the cost of the retrofitting your metal roof. This material not only greatly extends the life of your roof, it doesn’t cost as much as your standard metal roof replacement.

During installation, the original metal roof provides protection to your building’s interior so you can continue day-to-day operations while the work is being done. This protects your employees, your inventory, and doesn’t interrupt production.

Retrofitting is also eco-friendly. By not taking the roof apart and damaging / scrapping the materials, this reduces landfill waste, making re-roofing an appealing option for the environmentally-conscious.

When you retrofit over a metal roof, you are taking advantage of reusing your current roof insulation, as well as additional insulation from the membrane. This can help save on energy costs and keep building temperature regulated.

Disadvantages of Metal Retrofit Roofs
While having a metal retrofit roof installed over your existing metal roof can extend the life of your roof by up to 20 years, a complete metal roof installation is generally estimated to last between 30 – 60 years.

Keep in mind that comes at a significant cost increase, and can be more cost-effective to simply retrofit.

Commercial roofing types advantages and disadvantages they provide Part 3:
Commercial Pitched Roofs: Pros & Cons
While pitched roofs are seen in residential homes more than commercial buildings, they are still commonly used alongside flat and low-sloped rooftops.

Advantages of Pitched Roofs
The main positive aspect of pitched roofs is that the increased slope provides greater runoff for water and snow.

The steeper the roof structure, the easier it is for liquid and debris to roll off. Ultimately this means less risk for water buildup that could lead to leaks and mold damage.

Overall, having a steep-sloped roof could reduce your needs of repair and maintenance a bit compared to a flatter, less inclined roof.

Disadvantages of Pitched Roofs
Unfortunately, with the steep incline of a pitched roof it is significantly more difficult to perform maintenance and repair.

The need for increased safety procedures, transferring materials and difficulty maneuvering around the roof generally increases the costs of each individual installation, repair or maintenance service.

Commercial Roofing Types: Advantages and Disadvantages They Provide. 3 weeks ago we discussed the Pros and Cons of Flat Roofs.
Today we discuss the Pros and Cons of Low-Sloped Roofs.

Low-sloped roofs are often found on factories, warehouses, apartment buildings and other industrial buildings. They may first appear to be flat but they actually have a slight pitch.

Advantages of Low-Sloped Roofs
The pitch of low-sloped roofs allows for water runoff. The roof design directs the water to where it should go, such as valleys, saddles and drains. Roof area is less than with high-pitched roofs, requiring fewer square footage of roofing materials.
Low-sloped roofs offer easier and safer conditions for roofers to work on than high-pitched roofs or steep slope roofs.
Commercial roof installation, repair and replacement is easier to perform. There is less chance that the building owner will need to call repairmen out to manage water problems, since the slight pitch does not allow for standing water or puddling.
Air conditioners, solar panels and satellite dishes are easier to install and maintain on low-sloped commercial roofs than on roofs with a higher pitch.
The same variety of materials that are used on commercial flat roofs can be used on low-sloped roofs – rubber rolled roofing, EPDM, TPO, bitumen and modified bitumen. Modified bitumen have longer warranty times due to the additional thickness and superior sealing capabilities.

Disadvantages of Low-Sloped Roofs
Heavy snows that do not melt quickly can add weight to the roof. Building codes regarding low-sloped roof for your area must be adhered to precisely.

Commercial Roofing Types: Advantages and Disadvantages They Provide. This post is on of a few that will follow...
Commercial Flat Roofs: Pros & Cons
Flat roofs are one of the most common types of roof for commercial buildings.
Since the 1920s, flat roof systems have been a symbol of commercial & industrial commerce. Before this, pitched roofs were the most common architecture, even for larger commercial structures.
For building owners and roofing contractors throughout the world, the transition to flat roof types offer many benefits.
Advantages of Flat Roofs
Commercial flat roofs can be significantly more cost effective to build than pitched roofs or steep slope roofs because they require less material due to the fewer square feet to be covered.
They are easier and quicker to install, which can translate to a significant savings for the building owner. This also effects the ease and potential price of your next commercial roof repair.
Owners have many types of flat roofing materials and membranes to choose from – rubber rolled roofing, EPDM, PVC, TPO, bitumen, modified bitumen and built-up roofing.
While there are many different color choices to choose from with roofing membranes, however many building owners choose to stick with white.
This can help reduce energy waste from cooling costs due to it’s reflective properties.
Air conditioners can be moved from the ground to the roof. Solar panels and satellite dishes are easier to install on flat roofs than on pitched ones. These items are then less obvious from the curb or parking lot.
Maintenance and drain cleaning is easier on flat roofs since workmen can walk easily and safely, regardless of weather conditions.
Disadvantages of Flat Roofs
One of the most important disadvantages of flat roofs is poor drainage.
Standing water can degrade the roofing materials long before they normally would. One of the advantages of pitched roof styled buildings is not having to worry as much about drainage issues.
Material breakdown leads to leaking and water damage inside the building.
It is imperative that an experienced commercial roofing contractor with a good reputation for professional work do the installation or repairs in order to avoid problems with the roof.
The experienced team at Doublejack Construction understands where the drains must be located and the proper height to avoid puddling.

Weekends always seem to go quickly, but they’re longer than we think ! There are 60 hours between Friday 6pm and Monday 6am. Even if you sleep for 24 of those hours, that leaves 36 waking ones. Make the best of that 36!
😀Minimize your binge-watch - Some effortless fun is okay, but not the entire weekend.
😀Don't sleep in too late - If you sleep in for too long, it can disrupt your sleep cycle and make the weekend feel much shorter.
😀Take it easy on the chores - Pencil in just a few hours of errands and chores and fill the rest of the time with fun things, be creative, have a braai, go fishing......
😀Avoid the Sunday blues - Don't waste the whole day thinking about Monday. Plan something fun for Sunday night
😀Plan a weekend trip - Doing a lot of activities will make the two days feel even longer.
Happy Friday! May your 36 hours go by super slowly!

9 Important Things to Think About When Replacing Your Industrial Roofing
1. Your choice of roofing contractors
First of all, you need to know that no matter how durable your industrial roofing is, a faulty installation will only waste your time and money. Don’t be carried away by random contractors who randomly show up at your door and offer their “trusted” services.
It’s best to conduct your own research so you can make a well-informed choice.
2. Budget at hand
Where do you want your money to go? No matter what roofing you choose to replace your current roof, make sure to set a budget. For sure, the last thing you would want to face is unexpected roofing prices.
3. Building codes in your area
It’s important that you install a new industrial roofing based on the building codes in your geographical location. For instance, if your building is within an area that experiences frequent storms, you are limited to installing certain roofing types.
This is why you need to look for industrial roofing services that can assist you in negotiating local building codes.
4. Noise and disruptions
When you’re going to replace your roof, remember that it’s going to cause some noise and might disrupt your day-to-day operations.
5. Slope of new roof and drainage
Maintenance is one thing that you should really care about if you want to avoid frequent, costly repairs in the future. Drainage problems are common, especially among flat roofing systems.
The best way to avoid such problems is to pay attention to the various designs and options to help you avoid issues in drainage. The slope of a roof usually determines how well rain water drains.
6. Structural load and foot traffic
Are you planning to install solar panels on top of your industrial roof? How about solar panels? Other types of equipment? If so, you need to know that foot traffic and structural load are factors that shorten your roof’s lifespan.
7. Lifespan of roofing system
While in the process of choosing the best industrial roofing material, take into account the average lifespan of each roofing system. Other factors play a vital role in shortening or prolonging the life of your roof such as the frequency of maintenance and repairs, ventilation inside your building, and weather conditions in your area.
8. Energy efficiency and savings
Every business owner wants to get the best value for their money, especially with a roof replacement. With that, consider getting an energy-efficient roofing material. Energy efficient roofs work to minimize your utility bills.
They effectively reflect light, thereby reducing the amount of heat that enters your building. As a result, your air conditioning systems will not have to work harder to keep your interior temperature comfortable.
9. Maintenance
There are high maintenance roofs and low maintenance roofs. Depending on the weather conditions of your area.
