Maintaining Your Real Wood Roof Shakes

Below this article has a listing of  links that will help assist you in a “do it yourself” shake roof cleaning and proper maintenance. We have also included options for roof repair and replacement. To experience the proper life-cycle of your roof, your real wood shake roofing require regular maintenance, inspection, and repair.

Roof Inspections

Should you experience any leaks, or see signs of splitting, curling or crumbling, it is advised to have an inspection completed. GRS provides thorough inspections that include complete documentation of the status of your roof. With our inspections you will receive accurate photos, cost estimates, and a detailed plan to maintain your roof properly. Shakes require regular upkeep in order to maintain 100% efficiency.

Even the roof flashing behind skylights, chimneys, and valleys require adequate maintenance. If not properly maintained, you may begin to see the metal rusting or the caulking around the metal roofing beginning to crust. If this continues to deteriorate, it is guaranteed that you will begin to have leaks.

Roof Repair

????????????????????????????????????

The repair of shake roofs is often more extensive than shingle or metal roofs. When the time comes to do significant repairs, be sure to get a detailed roof inspection done so that you can see everything that needs to be completed on your roof in advance. GRS’s roof reports are highly detailed and show photos of all the areas that require immediate concern.

Repairs to metal roofs are quite often due to metal seams expanding or contracting, screw holes that have expanded over time, or roof penetrations that are improperly flashed.

The first step is to assess the repairs from a repair or remediation perspective. Some high end caulking, underlayment, and flashing knowledge is required. We use a journeyman that can assess the conduct the repairs to this end.

Once the repairs are done, you may have to consider one of the many options in metal roof coatings if your roof is low slope or irreparable.

Flat Metal Roofs – Low Slope Roofing Considerations

A roof coating or restoration will likely be required in addition to the repairs, especially if you have a flat or low slope system. We often service these types in commercial and industrial facilities.

Flat roofing is more difficult as “waterproofing” becomes key. A high slope roof can be looked at as a “watershed”, so are a little easier in terms of this type of maintenance.

There are many different options for metal roof restorations/roof coatings. A proper metal roof restoration, with the right people doing the application coupled with the right materials, should get you (conservatively) about ten years or more out of your metal roofing system. As well, a high quality coating will cost you about half the price of a brand new metal roof. In the meantime, you will have another decade free to plan for your roof replacement when it has reached end of life.

The reason a roof coating or restoration is typically required when you have run into metal roof issues especially flat ones) is that the issues are most often installation or design issues that cannot be permanently fixed. Any fix we do to mitigate a roof leakage, for example, will most often be temporary repairs.

One of the most common calls that come into our switchboard are those with reference to metal roofs.

Frequently Asked Questions:

From prospective buyers

  • How much are metal roofs? For the most part, people inherently know they are higher in price than a shingle roof.
  • How long does a metal roof last? Most folks know a metal roof is supposed to last longer than shingles.
  • What colours/profiles are available? Most often our clients have seen, at one point or another, a metal roof that really stood out which they really liked, and they have also seen others they did not like the look of at all.

From metal roof owners that have a leaky roof

  • Why does my metal roof leak?
  • How can I avoid leaks?
  • Are the seams leaking?
  • I can’t figure out if the leaks are coming from the screws.

In fact, we had a call this morning in which the caller, a golf course facility manager in Alberta, said he had changed out every screw on the roof (exposed fastening system) and caulked every screw head and seam and he still had two leaks he just could not pin down.

From metal roof owners frustrated by their leaky roof

  • I’m done with this roof, I’ve tried everything to stop the leaks. What other types of roofs are there?
  • I’m done trying to seal or caulk this roof, can we look at roof coating options?

The truth is, a metal roof is like any other roof. Metal roofing systems have benefits and they have inherent problems.

A metal roof can be the best roof you will ever own. It can be installed so that it does not leak, as well as look great and last almost a lifetime.

In saying that, we endeavour below to address the most important highlights of purchasing considerations, installation procedures, as well as leak repairs, coatings, and restorations.

quality metals:

People considering a metal roof purchase call us all the time with aesthetic and cost questions, and we cannot blame you. I know when I am searching for a new truck or my wife is looking for a new car, some of the first thoughts we have are regarding colour, style, and cost.

However, we should be thinking most in terms of what will get the job done right and what meets our needs most appropriately. Of course, budgets and pricing comes into play, but first and foremost the consideration should be: “what does it cost to do the job right?”

If a metal roof is incorrectly installed, or you have chosen a metal roofing system that has inherent problems or a low quality material was used, it will not so much matter how inexpensive it was when you consider the cost of leaks, repairs, roof coatings, and constant aggravations.

Case in point, to coat a metal roof or to do a metal roof restoration properly due to a leaking roof caused by a compromise during installation, it is about 50% to 70% of the cost of what it would have been to just install one properly the first time. Unfortunately, that is the most important thing to keep at the top of your mind when shopping for a metal roof.

The Right Questions

About the contractor

Experience with metal roofs specifically, regardless of its application, (residential, commercial, industrial) is paramount. Challenge the contractor, get references, check out their portfolio, and ask lots of questions. Unless their information is easily and publicly available, questions are your only weapon. You can find a guideline here for how to hire a roofing contractor on our main website.

The proposed metal roof system

When you are talking to roofing contractors about systems, I am not speaking of colours, cost, or the fancy names they give them [the systems]. Ask the contractor the follow questions. If the contractor can confidently carry this conversation with you, then you know you have a great chance at getting a roof that will, in fact, last near a lifetime and will have that aesthetic appeal you were looking for. A metal roof should not “oilcan”, should never leak, vent improperly, or require a full replacement after only a couple of years.

Questions:

Red metal roof, metal panels
Red metal roof, metal panels
  • If there are exposed fasteners, what kind are they?
  • If there are hidden fasteners, what kind of clips are being used and where are the clips fastened?
  • Are the clips being fastened directly to the roof deck; and if so, is there an underlay going under or over?
  • Ask whether the contractor will be hand cutting and wrapping the panels at the eave and at the ridge. If not at the eave, will you see the underside white of the panel from below when standing on the ground? If not, what are the wind lift considerations?
  • Is the system as monolithic as possible?
  • Are the seams hand crimped?
  • Where each seam is crimped or comes together, are they using a caulking underneath, or a caulking tape? How long does it last?
  • Will the underlay be synthetic, or tar paper? If it’s Ice & Water, what grade?
  • Will the underlayment be monolithic with base sheet torching?
  • If the contractor tries to “assure” you there will be no negative laps on the underlayment, gauge their reaction when you ask to see the roof for yourself.
  • Will there be strapping, and if so will it be going on before or after the underlayment
  • Will the system be able to breathe?
  • Will the metal panels be manufactured off-site? If so, what assurance is there that they will fit?

Once you have gone through this process, and the contractor’s answers have been vetted, then pick a colour, get a competitive and fair price, and pay your chosen roofers on time for a job well done.

When repairing a metal roof or considering a metal roof coating or restoration

This is a little easier than the questions you should be asking when you are considering a new metal roof.

Repairs are quite often due to the metal seams expanding or contracting, screw holes that have been expanded over time, or roof penetrations that are not flashed in properly.

The first step is to assess repairs from a remediation perspective. Some high end caulking, underlayment like Ice & Water, and flashing knowledge is required. We use a journeyman that can assess and conduct the repairs.

Once the repairs are done, then you will most likely have to do a roof coating at some point.

There are many different options for roof restorations that we will not go into here, but essentially a proper roof restoration with the right people doing the application should get you, under a conservative estimate, about ten more years out of your system and will cost you about 50% of the price of a new metal roof.

The reason a coating or roof restoration is typically required when you have run into metal roof issues is that they are most often installation or design ones that cannot be permanently fixed. Any fix we do to mitigate a leakage, for instance, will most often be temporary repairs.

For more information on roof coatings and metal roof systems, visit our roof repair and roofing replacement website. At the bottom of the main page their are links that discuss various issues, repairs, systems, hiring contractors, etc. You can also search this blog and the documents or links to the site by typing in your search key words and that may assist you also.

Ultimately, you can pick up the phone anytime and more often than not we have very experienced roofers that will either answer your call right away or one will get back to you in short order (we do our best to have our most senior roofers answer live on the front end as much as possible). We will give you a hand with whatever questions you may have.

Commercial Re-Roofing Process

General Roofing Systems Canada Repairs commercial roofs throughout Canada.

Whether you are a project manager, engineer, architect, business owner, or facility manager, planning a commercial re-roof is a significant multifaceted task where due diligence becomes essential.

In our estimation, the most important thing to keep at the top of your mind when considering a commercial re-roof is the experience of the contractor you are entrusting.

From roof analysis to the design phase, and from the start of your project to its conclusion, as well as the after-installation service, roofing experience is key. Experience trumps all other considerations. A roofing contractor that does not have the appropriate, successful experience is ill-equipped to be sure a commercial re-roof is successful. The consequence of an error when planning or executing a flat roof replacement can be disastrous. The cheapest or most convenient roofing contractor may not be the best long term choice.

Flat Roof Membranes: Sample Customer Query

Below you will find a customer inquiry we had in Fall 2011 referencing flat roof membranes for a new inner-city home our customer is having constructed in Calgary, Alberta.

This fellow was the unfortunate recipient of what occurs in the flat roofing industry every year – there is a year-end tsunami we as roofers experience when panicking clients need to have their flat roofing systems maintained, replaced, or repaired. It turns into an “all hands on deck” period of time during this so-called tsunami, especially for our commercial roof and industrial roof clients. This particular flat roof membrane query unfortunately took some time to return, but the client was gracious nonetheless. Please note that the quoted blocks in italics are our responses to the client’s questions.

< Start of Email >

Well thank you very much for the in-depth follow-up, it is much appreciated.
I do have several questions, some of which may overlap with others. Please bear with me, my inexperience with flat-roofing necessitates a bit more research, and there seem to be so many systems that it is difficult to know which is more appropriate than the next.
1. With the liquid rubber roof coating system, will the membrane simply seal around any punctures in the roof (i.e. irrigation line for the planter box, roof skylight openings, scuppers in the parapet), or does this require separate attention?
Liquid Rubber roofing, at least the specification GRS applies liquid rubber roof coating to is a process of steps. The first being cleaning the substrate or roof deck, next is preparing all roof penetrations, fasteners, expansion joints, connections, etc with a scrim fabric sheet (polyester woven scrims) and trowel grade liquid rubber (done by hand with trowel, squeegees, and rollers), then a flood coat of liquid rubber (sprayed), and then the final stage of liquid rubber roof application is a final spray coat of liquid rubber. Another coat is optional to add colour. This is done with an acrylic top coat. The liquid spray on acrylic roof coat can be specifically tinted to the desired color.
2. Do you recommend, as per the liquid rubber system, a 2-layer approach (using the Sealroof A-100 over top the Sealroof B-200), in the same way you would do a 2 or 3-layer torch on system? In this way, you could apply a white top-coat < GAF Top Coat > to help reduce the heat island effect on the roof and help alleviate the temperature variation in Calgary?
The GRS process of application for liquid rubber roofing, flat roofing, and pitched roofing is typically more involved than most specifications our roofers see day-to-day in the marketplace. Specific to Liquid Rubber roofing, our system of application is detailed at point 1 above. Top coating the liquid rubber is also detailed above and there is an article linked to our website specific to the white and black decision with flat roof membranes found here (Carlisle-Syntec Article).
3. My current details include a sloped insulation for added R-value, over top of a ventilated ceiling cavity with vents in the parapet wall. Who do you get your sloped insulation from, and is it custom made for the project, or does it require labour to adjust it? Is it possible to simply install sleepers above the roof joists to achieve slope and sheath the roof and apply the membrane overtop of that, and sacrifice the added R-value of the sloped insulation? Is that normal?
Sloped insulation for flat roof structures is a common method. Many designers will specify the framing of the substrate to be sloped also as an alternative. We source our sloped roof insulation from a number of companies. One we often use in your area is Plasti-Fab. It is a pre-engineered sloped insulation that is delivered with a diagram for installation. We would have difficulty answering to the roof sleepers question until on site or more discussion was had.
4. You mentioned custom metal flashings, and I am wondering what the scope of your roofing will entail (in other words, do you also provide flashing around skylights, and around scupper holes for drainage)?
Various roof flashing required we provide to our flat roof customers. Typically, roof skylights will have flashing kits, but various designs will have us custom fabricating metal. Whether it is flat roof cap flashing, cant flashing, edge flashing, or various custom flashing for roof membranes… we fabricate and install it.
5. You mentioned the TPO system (which I have been recommended to use from a colleague) is more suited for Vancouver than for Calgary. What are the reasons for this? Is it strictly based on freeze/thaw considerations or total precipitation, snow loads, or some other reason? One of my biggest concerns is that the roof membrane will not stand up to the temperature differentials we all know that Calgary is susceptible to.
Answering to the environmental impact to various roof membranes (such as freeze thaw) is a complicated topic. SBS Modified Bitumen (torch on) and Built Up Roofing (Tar and Gravel) has been a mainstay for so long, with Alberta holding to it longer than most other areas of the world. My comment to TPO or any roof membrane that is reflective or light colored is more specific to the energy efficiency of roofing systems or flat roof membranes. In Alberta, many see it as counter productive to have a reflective roof as more often than not we have our heat on than we do the air conditioning. This too is a diverse conversation. Our web site under the flat roofing section on the right column has links to articles. With respect to how each membrane will hold up specific to Calgary, that is a difficult question. TPO, PVC, EPDM single ply flat roof membranes are being installed every day in Calgary, as are the traditional SBS modified and BUR flat roof membranes. SPF – Spray Foam Roofing is another roof membrane option and then the Liquid Rubber roof membranes. At issue is that most roof membranes have not been installed for a long enough duration in the Calgary market for an excellent evaluation of performance. For example, the liquid rubber we are referring to in this instance has only been available for shy of a decade and not widely used until very recently. Our comfort is in that we simply add more liquid rubber membrane if there were to be failures. When single ply membranes were first introduced the remediation of early failures in the membrane was much more complicated than with liquid rubber roof membranes – with liquid rubber we simply apply more liquid rubber if failures were to occur. In saying all of that, we have significant liquid rubber roof membrane applied over the last 3 years with no failure to date.
6. Is a Torch on SBS system the only one which requires a ballast? Or does the liquid rubber also require a covering to reduce UV penetration, etc? Would adding Ballast prolong the life of some of these other systems?
Ballasting a roof membrane is for the purpose of keeping the roof membrane to the roof deck – wind uplift etc. For example, a ballasted EPDM roof membrane holds the EPDM down so the wind doesn’t take the membrane away. The EPDM is adhered at the seams and loose laid to the insulation or roof deck with the roof ballast (rock) covering the membrane. Inverted loos laid systems have the roof insulation laid on top of the EPDM roof membrane with the rock or roof ballast on top of the insulation. Single ply roof membranes (EPDM, TPO, PVC) can be mechanically fastened (not requiring roof membrane ballast), Loose Laid (requiring roof membrane ballast), or Fully Adhered (not requiring roof membrane ballast). With SBS Modified Torch on roofing their is no ballast required as the SBS membrane is torched or fastened to the system by way of torching or with adhesives etc. The UV is not an issue also with SBS Modified Roof Membranes as the cap sheet (or second layer of roof membrane) has granules attached that keep UV away from the Bitumen. With Built Up Roof Membranes (or BUR) the layers of bitumen are covered with an inset top layer of gravel to keep the UV away from the bitumen in the roof membranes (typically a four layer membrane system). The gravel in this instance is not for ballasting, it is only for the purpose of UV resistance. In the case of Liquid Rubber Roof Membranes, the liquid rubber manufacturers claim UV resistance with-out the requirement of granules as with SBS membranes or gravel as with BUR or Built Up Roof Membranes.
7. Do you have specific price per square foot values for each of these products, or is the quote system more complex than that (in terms of metal flashing, scupper detailing, etc.)?
Specific pricing for flat roof membranes is wisely derived after review of the construction drawings and discussion with the parties that can affect construction processes. In your instance, specific pricing for the various roof membranes can be accomplished by way of the construction drawings provided.
It seems from your email that the liquid rubber system is more costly initially and less costly over the lifespan of the roof. Can you list the roof systems according to their initial cost for installation? I am very interested in the liquid rubber system, but a little hesitant regarding the price. My understanding was that a modified Torch-on SBS was cheaper than some of the other systems, like a TPO membrane or a soprema system.
Pricing for all flat roof membrane systems are similar. Tar and Gravel Roof membranes (or BUR) will tend to be more costly due to the extensive labour, SBS Modified should be similar or perhaps a touch more than the Single Ply roof membranes (TPO, PVC, EPDM), TOUGH ROOF (which is a concept built on the strength of the traditional Built Up Flat Roof with an elastomeric top coat) would be on the higher side of the pack, and Liquid Rubber systems (if done per the specification of membrane application that we use) will be in line with Single Ply. More often than not, with roof membrane choices and pricing, you will receive varying opinions that are usually specific to what the roof membrane applicator installs most, what roof membrane the roofer is certified to install, etc. The widest divergence we see in flat roof membrane pricing is not necessarily the roof membrane material that will be used, but the process of application of the roof membrane itself and whether the flat roofing company has all the other operating costs that credible flat roof companies can have due to safety, staff remittances, benefits, company vehicles, licensing, insurances, etc.
My roof works out to be about 1150 sq. ft. (inside parapet), with the planter on the second storey being about 23 sq. ft. Would you be able to work out a few prices using the Torch-on SBS, liquid rubber, EPDM, and Soprema systems that you install?
As it applies to SBS Modified, we typically use when available to us the IKO SBS Modified Bitumen products vs Soprema. Not that we see IKO superior, it is just what our company typically uses for SBS roof membrane unless specified otherwise. I am personally a Soprema certified installer and I don’t see much of a difference either way – both IKO and Soperma produce a quality SBS Modified Roof Membrane as I see it. With EPDM, we regularly install Firestone and Mulehide EPDM (I believe Carlisle manufacturers the Mulehide EPDM, but I could be wrong). With TPO we install Firestone and Mulehide regularly also. Liquid Rubber roof membranes come in various forms, because we are installing so much of the liquid rubber roof membranes we have various specifications for application and material for the membranes. I will price yours specific to how we see it best applied and according to the manufacturer(s) we see as best for your roof membrane.
The pricing for the various roof membranes I will forward in a separate email.
Thanks again for your comprehensive response. You’ve been most helpful.
