Maintenance, Restoration, or Replacement?

When reviewing the process of commercial roofing, the first step is to decide what method of roofing is required. Of course, there will be decisions in regards to the metal used, yet this all depends on whether or not you have a flat roof. For example, you may be looking to repair your roof, perform annual maintenance, completely replace or restore your existing system.

Repairing Your Commercial Roof

Commercial roofing repairs are best done by a roofing contractor that complete repairs on a daily basis and who is aware of all the commonly accepted standards. GRS employees are highly trained to work with all varieties of commercial roofs; our crews undergo extensive training that help them to assess and repair any and all issues. Flat roof repairs are specific to the type of commercial roof such as; Tar and Gravel, Torch-on SBS, TPO, EPDM, PVC, Roof Coatings, or SPF – Spray Foam. It is important to have roofers that are aware of the type of commercial roof membrane that is being repaired.

Metal roof repairs on commercial buildings are also type-specific. These common types are are metal cladding roofs, standing seam metal roof systems, and coatings with a reflective coating or black rubber liquid coating.

The objective is to locate a commercial roofing contractor that has technicians with the knowledge of all commercial roof types.

Preventative Maintenance

Commercial roofing systems require regular maintenance. In most instances maintenance on a commercial roof (flat roof) should be completed a minimum of twice a year. It is recommended to have this completed once in the fall and once in the spring. GRS has specific commercial roofers that specialize in roof maintenance. Our roofers are aware what to look for and how to solve specific commercial roof problems. Our web site contains a step by step list for commercial flat roofing repair and maintenance:

Metal Roof Maintenance

Metal commercial roof systems also require regular maintenance. Maintenance should be performed on all the metal seams, metal roof fasteners, and roof openings. Sometimes this only requires a simple process of caulking (be sure to use high-end metal caulking). Yet with scenarios, when the metal roof is beginning to fail due to rust or expansion/contraction of the metal seams and holes for the fasteners, more extensive roof repair or roof restoration becomes a necessity. This is another area where it would be beneficial to have type-specific contractors completing the work.

Our roofing blog has numerous articles regarding metal roofing, metal roof repair, and metal roof restoration. Simply search your topic by category on the left hand side of the page.

Roof Restoration

Restoring Your metal or flat commercial Roof when regular commercial roof repair and maintenance doesn’t alleviate the problems you are experiencing with your metal or flat roof, more extensive restoration is required. One significant advantage of restoring your commercial roof rather than replacing it is the tax benefit. Roof restoration is considered maintenance and not typically considered a capital cost as it would with a complete roof replacement.

Metal roof systems are filled with challenges, especially in colder climates like Alberta and Saskatchewan. For example, in Edmonton, AB last winter, the snow loads were so immense with the ice damming on the metal roofs, as well as the heavy weight loads, that several metal commercial roofs were affected. Our metal restoration crews have been working nonstop since last winter to repair and restore metal roof systems on numerous commercial and industrial facilities. The advantage of having a metal roof on your commercial facility is the longevity of the material. Metal roofs are known to last several decades before requiring full replacemetns.

The inherent challenge with commercial metal roofing is that the metal expands and contracts. This is especially true in our unpredictable Western Canadian climate. Unfortunately, many leaks occur as a consequence.

When thinking about restoring a metal roof it simply comes down to two things. First is whether or not you would want white reflective metal roof restoration, or do you want a black roof?

In today’s market, there are several advancements to metal roof coatings. One primary example would be the liquid rubber polymers that were created for waterproofing commercial metal roof systems.

The challenge with reflective coatings for metal roofs is that coatings such as acrylic, which are highly reflective, also contain the disadvantage of cracking and peeling. The important items to be considered when choosing a restoration process or coating for your commercial roof is to be sure that the roofing contractor you hire is experienced and knowledgeable as to what is required. It is also important to inspect the coating material being used on your commercial roof. This is important due to market factors drastically changing over the past few years.

The same applies for flat roofing as it does for metal as we described above.
Coatings for commercial roof systems in this day and age have radically changed as restoring a flat roof today is not the same it was 3 years ago. At one time (and we still restore tar and gravel commercial flat roof this way), we would re-coat flat roofs with bitumen or tar from a hot kettle. Or in the case of a rubberized asphalt commercial flat roof, we would re-coat with hot rubberized asphalt.

Commercial roofing today has many more options. More recently many commercial property owners have been having roofing contractors spray foam their roof systems. With this process you skirt around the entire old method all together. Once the spray foam has been laid down you then add an acrylic reflective top coat to the SPF.

The process of spraying foam over an existing commercial roof is highly effective and cost efficient  – although this isn’t always the best method for an extended amount of time. There are coatings that are asphalt based that contain fiberglass that can be used to coat roof systems and emulsions. And then more recently elastomeric coatings have become available. This newer type sprays right over top of the existing system. Finally the most recent to come forward on the market is liquid rubber coating. Liquid rubber coating has been an excellent success for both roofers and owners alike.

Roof Overlays or Retrofits

An example of a roof overlay or retrofit is when your current commercial roof system has a tar and gravel roof. Instead of coating the roof and completely ripping out the roof and replacing it entirely, you can retrofit or recover it. There are many forms of flat roof recovery. One method is for our roofers to scrape or spud the gravel off. Our roofers will then install an insulation board and the roofing membrane right over top. For more information on retrofitting you can reference our blog and website.

Complete Roof Replacement

Complete roof replacements are a massive undertaking. In order to have this procedure completed correctly it is extremely important to choose the right contractor for your project. The contractor you choose must have roofers that are trained and have accurate knowledge of all roofing systems. In addition to this you will need to choose the right method of roof replacement or retrofit. Once you have done that, the next item to select will be the right membrane and search out a reasonable competitive price.

GRS has written extensive articles to assist commercial property owners with the process of completing roof replacements, some of which are on our blog and website. Here are some articles for your consideration when planning a commercial roof replacement:

New Generation of Roof Coatings

With every new product or technique there is always some skepticism to be had among both technicians and buyers alike. Yet with the new elastomeric rubber roof coatings, this has proven to be a positive experience among all who use/receive it. Our crews have been quite satisfied with the coatings that are placed down on the metal and flat roof systems.

Roof Coatings for Restoration, Repair, Maintenance

Liquid rubber elastomeric polymer roof coatings have proven to be quite efficient in the field. When metal or flat roof systems need repair, this new generation of roof coatings is something that should be considered for your roof repair or restoration process.

Roof Coating Warranty and Guarantee

Our liquid rubber systems come with a 10 year, no hassle warranty from the manufacturer. Yet GRS is able to extend this guarantee for an additional 10 years, giving owners a full 20 year warranty. In addition to this, our lifetime workmanship guarantee would also be honoured, therefore providing a full lifetime warranty for the duration you own the building.

Roof Coating – Why does a Metal or Flat Roof Coated in Rubber work so well?

Roof systems expand and contract and buildings move. The secret to the new generation of roof coatings is the coating elongation (900% or more) – they are suited to cold Canadian winters and summers. The new coatings stretch and move with the metal or flat roof systems. They are monolithic (there are no openings or seams) and they stretch. Metal roofs can be quite difficult to repair; finding the source of the leaks can prove to be quite a frustrating experience for roofers, business owners and homeowners alike.

Metal roof seams, fastener holes, fastener gasket, flashing, vents, etc. can all move, and expand/contract. Seams between panels become larger, fastener holes become larger over time, the rubber gaskets on the screws deteriorate over time from UV, and flashing gives way to ice dams and expansion and contraction over time. The new roof coating is able to solve this problem by providing a 100% expansion rate to all surfaces.

Cost of Roof Coatings, Roof Replacements, and Roof Repairs

The cost to temporarily repair your roof (whether it is a flat roof or metal roof) is typically around 10% of the value of the roof (average over lifetime of roof). The cost to replace your metal or flat roof is roughly between 8.00 and 20.00 per square foot. Essentially a roof coating will only cost you half of what a full replacement would. Both coating and roof replacements have the same length of warranties. And should you choose to go with a roof coating it is tax deductible as it is considered maintenance.

Flat Roof Repair, Coatings, and Restoration

General Roofing Systems Canada provides flat roof coatings throughout Canada. Roof coatings are completed in the following cities: Calgary, Red Deer, Edmonton, Fort McMurray, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Banff, Cranbrook, Kelowna, Vancouver, Whistler, Winnipeg, Toronto and points between. British Columbia. Alberta. Saskatchewan. Manitoba. Ontario.

Technology has changed. Today’s flat roof coating technologies allow for GRS to offer highly effective flat roof coatings that perform extremely well, have relatively lengthy manufacturer warranties, possess tax deductible benefits that a new flat roof system can’t offer, and are economically more feasible than traditional roof maintenance systems (the new flat roof coatings have excellent life cycle costs not available in past).

 

Flat roof coatings available today are an excellent, predictable solution for waterproofing new or old flat roofs (low slope roofs). GRS has cool roof coatings (“reflective white coatings”) and we also supply and install black rubberized flat roof coatings (which are more commonly used in Canada). We have recently been installing a number of flat roof and metal roof coatings throughout Western Canada (early in the 2011 season) and we will be posting the process of those installations to our blog as soon as photos start coming in from the sites.

GRS flat roof coatings are an excellent solution for flat roof repair over most aged flat roofing materials except coat tar roofing (in which case a roof recovery membrane system is better suited). As a side note, we can offer an “out of the box” manufacturer warranty on the new flat roof coatings that is 10 years, and on flat roof recovery systems 20 years is available from the manufacturer.

Technology in both categories of flat roof remediation or restoration has certainly changed in recent years. GRS installs flat roof coatings over metal roofs (the photo above shows a metal roof coating in progress in Leduc, AB just south of Edmonton), BUR Tar and Gravel Roofing, Modified Bitumen SBS Torch Down Roofing, and Single Ply Roofing such as EPDM, PVC, TPO, etc.
Our flat roof restoration systems utilizing roof coatings allow our clients to avoid a complete re-roof tear-off; they complete the flat roof repair or restoration process faster; coatings lower flat roof maintenance and replacement life cycle costs; and roof coatings (or roof recovery systems) eliminate landfill costs.
Coatings are applied using a brush, roller, squeegee, and/or sprayers as required. The coatings cure quickly (set instantly and cure within 48 hours). With excellent advancements in roof coatings our client base has rapidly grown also, GRS has many satisfied commercial and industrial clients that can attest to the remarkable advances in product deliverables in this particular segment of the roofing maintenance industry. We strongly encourage anyone with a flat roof or a metal roof that is seeking replacement, repair, or maintenance to look in to this excellent solution.

 

In addition to the new roof coating products being an excellent solution and alternative to complete flat roof or metal roof replacement, many of our flat roof coatings are green, environmentally friendly roof coatings. A few points of note:

  • They carry a 10 year roof coating warranty.
  • UV resistant.
  • Have  tax deductible benefits as they are considered maintenance and not a new roof.
  • Coatings are cold-applied roof systems (no open flame is used on the roof).
  • Many of our roof coating systems do not contain any toxins or VOCs.
  • Highly elastomeric – in most cases are equal to or exceed 850% elongation with 95% recovery – that is a very elastomeric roof coating – they are able to adapt to surface movement and thermal changes like few flat roof solutions can.

Industrial Roofing: Roof Coatings, Metal Roof Restoration and Roof Sealants

General Roofing Systems Canada Services Industrial Roofing and Roof Coatings throughout Canada including Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler, and points between.

Some of the most common issues our clients call us about are low slope metal roofs that expand and contract and leak and flat roof systems that are very costly to replace. Our clients are looking for ways to extend the life of their flat roofs or metal roofing systems.

Truth is, a flat roof or a metal roof replacement is expensive, and there are excellent ways to set off much of the cost of a complete roof replacement.

If you have a low slope metal roof, chances are you have aggravating leak issues. Metal expands and contracts, the seams on metal roofs leak and the roof penetrations on metal roofs leak. A complete metal roof replacement isn’t necessary and replacing a metal roof doesn’t solve the metal roof leak issue anyway.

Roof Coatings for flat roofing and metal roofing available in today’s marketplace are very effective – we can’t stress enough our success in this area of roof maintenance. Premium roof coatings available now solve the aggravating roof sealant and caulking issues and flat roof and metal roof coatings are an excellent alternative to a complete re-roofing.

Premium Roof Coatings now carry a 10 year manufacturer warranty. The product is literally bullet proof when installed and has huge elasticity. The pricing for a premium roof coating is very competitive when considering flat roof or metal roof full life cycle costs, a roof coating is maintenance work so there are tax benefits, and the best part about the roof coatings available now is the new generation of roof coatings perform very, very well. They eliminate the aggravation that comes with metal roof problems and they can save you a lot of the expense associated with constant metal or flat roof repairs, roof maintenance.

Roof coatings set off the need for a complete re-roof/roof replacement for years or even decades.

The photo in this post is of a roof coating crew that completed an industrial roof coating in Lloydminster, AB. The industrial metal roof they coated in rubber is around 20000 sq. ft. and the coating work took just under a week. The roofers pressured washed the metal cladding first and then applied a rubberized roof coating to the metal roof cladded deck. Prior to the field of the metal roof being coated in the elastomeric liquid rubber, a trowel grade liquid rubber is applied to the screws (fasteners), to the seams of the metal cladding, and to any roof penetrations. Then the liquid elastomeric rubber roof coating is applied to the main field area of the roof. Now when this metal roof expands or contracts the seams and the roof penetrations are not going to let water in and the roof won’t leak. Additionally, the life cycle of the roof has been extended for 10 to 20 years and the tax benefit is realized.
