How does the quote process work?

The process Goodmen Roofing uses is standardized, ensuring a job done right every time

Step 1: Request for Estimate Our system ensures that our estimator will contact you within 3 business days, possibly sooner.

Step 2: Schedule a Site Visit A meeting and/or a site visit is determined during the initial contact.

Step 3: Estimating Our estimator customizes a line item quote detailing the products we will be using and the process involved on your project. Warranty information and projected timeline are also included. Your Goodmen Roofing Estimate is emailed, dropped off or faxed over. We will follow up to ensure receipt and to discuss. Another meeting may be set up at this time.

Step 4: Project Approval One you have approved the estimate, we enter your job into our internal system and all the information is supplied to our Field Supervisor, who will be your first point of contact for the duration of the project.

Step 5: Roofing Roofing takes place and the Field Supervisor will keep you up to date with progress, any issues that arise and provide photos of the project progress. Barring any unforeseen circumstances, your Field Supervisor will ensure that your job is done properly on time and on budget.

Step 6: Completion The Field Supervisor will meet with you on site to confirm completion of work. The project is then inspected by the Field Supervisor or by a third party inspector (depending on the materials used, this will have been detailed in the estimate).

Step 7: Delivery Upon receipt of payment your warranty is issued. At this time we will discuss a recommended Maintenance Plan.

Should I look at price alone?

This is an easy questions to answer. NO. Always take into consideration that there are many roofing products on the market today. Even if you get an estimate for the same type of roof system the products and quality are still different. The best way around this is to do some research or ask the estimator what the difference is. Also, you may not be getting the same roof system. If the quotes are different, and price varies make sure to call and ask. Don’t just assume a contractor is more expensive and trying to gouge the customer. There may be a reason the price is higher. Here at Goodmen Roofing we look at each individual project and come up with the proper system to install based on the specifications in the industry. Very seldom are we the cheapest but we always do the job right.

My roof is leaking and I need a roof right away - what should I do?

The best answer to this is to have a reputable company come out and assess and make a repair. This will buy you some time to go through the proper process of getting a quality roofer. Odds are good that if a roofer provides a quote and can start your job within a few days, there may be a reason that they are not busy. This is not always the case but it may raise a red flag.

I am not sure if my roof needs to be replaced or repaired. Can you help with this?

Yes, We would be more than happy to come have a look at your project and give you our professional opinion. We will let you know if you need to re-roof, repair, or set you up with a maintenance plan to prolong your roof and give you time to budget for a re-roof.

How can I tell if I have hail or wind damage?

Unfortunately we live in a hail and wind zone in Alberta. Most of us have either had to re-roof or know someone who has in the past few years. Here are the most common signs of hail and wind damage to your roof:

  1. Are there lots of granules (the rock that is on the top side of a shingle) on the ground or coming out of your down spouts after a rainfall? If so you may have hail damage. It could also be that your roof is wearing out but if you never noticed it before a hail storm it is probably caused by hail.
  2. Are there broken pieces of shingles in your yard? This is a sure sign of wind damage but it may also be a sign of hail damage.
  3. There are shingles lifting when the wind blows. This may be a sign of wind damage. It may also be that your roof is worn out. If your roof was just re-roofed the shingles are not tabbing properly. Have the roofer come back and manually tar each shingle so they tab together.
  4. If you can get on your roof, are there any dented metals, broken air vents or areas where the granule loss is significant? If you can see any of these you may have hail damage.

How do I ensure my roof is ready for winter?

One of the hardest things on a roof is an infamous Canadian winter. Tis the season for an assortment of ‘wear and tear’ issues that can drastically reduce the life of your roof, not to mention unwanted and avoidable leaks.

Here’s a short list of these ‘wear and tear’ issues and what you can do to prevent them:

Debris (leaves, branches, etc)
Debris must be removed from your roof BEFORE the snow flies. Gutters and drains blocked with debris hold water when snow melts. When it freezes (overnight for example), the expansion is intense enough to split rocks, so you can only imagine what it does to your roof system!

Caulking/mastics
Check your chimney stacks, plumbing vent stacks, roof curbs, gum-cups and metal flashings to ensure that the existing caulking hasn’t dried up and/or peeled away. If repair is needed, DO NOT simply caulk over the old. You need to remove it and replace it with a high grade sealant. Note: there are specific sealants for this and silicone is not one of them.

Flashings
Flashings provide two services on your roof; one is for aesthetics the other, primary function, is to cover and protect the roofing materials terminated beneath them. Flashings should be checked annually and/or after high winds to ensure they’re fastened properly and won’t blow off.

Weight
Snow load is typically not an issue with roof systems in Alberta as our codes ensure that buildings are designed, engineered and built to withstand the snow load weight for our region (search the internet for specifics if that information is required). Surprisingly, one of the worst things you can do to your roof is shovel off the snow! Most roofing products get brittle in colder weather and walking on your roof and shoveling or scraping them off will only aggravate them further. Rule of thumb: Unless there’s a 100 year record of snow accumulation or your building is 20 years+ and older, stay off it. A good roofing contractor can assist in both situations.

Product Lifespan
What does this mean? In short, all roofing products will eventually wear out and need to be replaced. When inspecting your roof have a close look at the overall condition to see where it is in its ‘lifespan’. Will it make it through another winter? Am I going to have leaks in the spring? Can I re-roof now or do I have to wait? These questions are best answered and explained by your roofing contractor.
Although most commercial properties retain a maintenance person or company, the roof seems to be one area of many buildings that is overlooked; out of sight, out of mind…

Your best insurance against ‘winter roof issues’ is to call a professional roofing contractor to assist you with ‘winterizing’ your roof, providing maintenance pre-winter and to assess your roofs lifespan. I know that if I have a toothache, I don’t get my neighbor’s kid to fix it, I call a Dentist; they’re the professionals.

Does Rot affect buildings in the Calgary area?

Roof-rotIt’s quite surprising how many buildings in and around Calgary are been plagued with common rot issues; wood building components (structural and non-structural) that have had long term exposure to moisture caused by leaks, condensation and/or higher than normal humidity.

Rot occurs when moisture gets into the cellulose fibres of wood and begins the ‘natural’ decay process. Rot is a sneaky devil and not always easy to detect as it likes to ‘hide’ in places we can’t see; this is where moisture gets trapped and the rot begins. Rot found within a building’s exterior envelope usually occurs under the exterior covering; walls and/or roofing systems. Rot is the natural breaking down of organic cellulose fibres (wood).

Rot is one of the most destructive, expensive and frustrating repairs one can have with a building and gone undetected and addressed, can lead to more serious issues like building closures due to structural integrity, poor air quality (from mold and mildew) and many other related issues.

Goodmen Roofing has been involved in numerous restoration projects that were plagued by rot and takes pride in our general knowledge of these issues and how to rectify them. Some of the most common causes of rot that we have encountered are:
Decks with leaking membranes
Windows and doors with failing gaskets and/or sealants
Roofs with leaks
High humidity trapped within a wall, roof or attic space due to poor (or lack of a proper) vapor barrier or venting

We work closely with several engineering, consulting and building envelope design authorities to ensure the restoration is done properly and all to code. In most cases, remediation can occur while the building is occupied. The major cost and problems occur when it goes undetected for too long. If you want to know if rot is lurking in your commercial building, contact someone with proven experience in building envelope sciences such as a reputable roofer, consultant, engineer or general contractor.

Do you have guidelines for a successful Roof Replacement?

What to look for and who to hire

Replacing your roof is a huge undertaking and can be rather expensive; it’s a decision that needs to be thoroughly thought out.

When making your decision, keep in mind that your roof, along with the exterior finishes of your building are what protects everything inside; the structural, the electrical, the mechanical, the finishes and all the furnishings and contents. Take these steps to ensure you’re getting what you want, expect and deserve:

  1. Get written estimates from at lease 3 qualified contractors (see notes below). Ensure the quotes are comparing similar products and accessories. Ask for clarification if not clear and NEVER take verbal promises or assurances as truth; get it in writing! Goodmen Roofing provides clearly written and detailed estimates and our testimonials speak for our reputation.
  2. A good rule of thumb is NOT to accept a quote based solely on price. Real low bids drive down the market, only serve to feed poor quality products, inferior workmanship by cutting corners and lack of after sales services; all of which hurt the end user – you. Then you have the highest quoted price; what are you paying for the best of the best or maybe the company is simply very busy and has priced accordingly? These are questions that your research and follow-up with references (see notes below) will prove to be invaluable. Focus on the middle quote you’ve received. Quite often, the middle price quote is the one that has everything covered and is providing the best bang for your buck. Although this sounds like common sense, you still need to do your homework.

Qualified Contractors

  • Get referrals and be sure to call them. Remember, verbal ‘confirmations or promises’ should not be accepted as the truth; get it in writing.
  • How many years has the contractor been in business?
  • Get proof of their WCB, General Liability, COR & ISN (if applicable) and/or other Accreditations.

Comparing Apples to Apples

  • What are the exact products being used? Get brand and product names then research them online.
  • What type and length of warranty is being provided or offered? Read the fine print.
  • What’s the timeframe? If it seems reasonable, then it probably is.
  • When the work is being done, ensure the products being used are the ones you agreed to; any reputable contractor will be more than pleased to prove this to you.

Things to Watch Out for

  • Bad-mouthing other products, contractors or customers.
  • Time sensitive offers; they’re usually tricky sales tactics that benefit no one.
  • And remember… If something sounds to good to be true, it usually is!

If you want a contractor who sticks to their word, consider whether or not they did everything they said they would in regard to the estimate. Doing so is a good way to evaluate the future of your project and prevent any possible setbacks due to bad work ethic.

Can you compare and contrast commercial roof products?

PVC (Polyvinyl Chloride)

PVC Roof membranes are most commonly installed as a single ply system that utilizes hot air welding technology. This is the flat roofing material of choice.  Goodmen Roofing is an accredited installer of PVC roof systems and is our #1 choice and recommendation.

Pros:

  • Pre-manufactured rolls in widths of up to 22’ wide x 100’ long can eliminate up to 85% of field welding
  • Pre-manufactured through-roof drain, pipe, stack and curb flashings reduce the human welding error by 85%
  • Purpose made, safety edge walk-pads protect the roof membrane and service personnel while on the roof
  • Certain manufacturers provide non-prorated warranties that cover both labour and materials
  • Life expectancy during accelerated 50 years has been accelerated
  • Most PVC membranes are 100% recyclable
  • Canadian climate performance
  • Highly resistant to numerous chemicals and liquids, making it ideal for a wide variety of applications
  • Available in many colors with options for custom colours as well
  • White PVC membranes reflect the solar energy of the sun; reducing A/C costs during hot summer months
  • All seaming is performed with extremely safe, hot air; there are no tar kettles or open flame torches required
  • Goodmen Roofing prefers to install PVC over all other flat roofing products due to the quality and longevity of this product

Cons:

  • Single ply membranes are subject to physical damages caused by careless service personnel
  • Are extremely slippery when wet and/or snow and ice covered (the reason for purpose made walk-pads)
  • Not patchable with asphaltic based mastics or caulking
  • Most commonly mechanically fastened which can be hazardous if the underside of the roof deck has cables, conduits, gas lines or other attached to the underside of the deck (this is illegal to do, but some older buildings were constructed that way, so a visual inspection prior to using a mechanically attached system must be performed)

SBS (Styrene Butadiene Styrene)

SBS is a 2-ply, granule coated modified bitumen membrane system applied with cold adhesives, hot tar and/or open flame torches.  Goodmen Roofing only installs SBS systems using cold application methods (for safety reasons) and is our second roof system choice after PVC systems.

Pros:   

  • 2-ply ensures a thick, robust flat roof covering
  • Low maintenance
  • Canadian climate performance
  • Available in several colours, thicknesses and applications
  • Cold applied systems are safe but increase the overall cost of materials and labour

Cons:

  • Hot tar and flame applied SBS systems are extremely dangerous and subject to human error
  • Granule surface that protects the bitumen wears away and the UV protection it provides is compromised
  • Ponding water affects the long-term performance and not covered under the manufacturer’s warranty
  • Future replacement and disposal of mixed bitumen based products goes straight to the landfill

One meter wide rolled goods create 100’s of feet of seams that are subject to failure (often installation error)

TPO (ethylene propylene rubber)

TPO membranes are installed as a single ply system that utilizes hot air welding technology.

Goodmen Roofing is experienced in TPO roof system installations and repairs.

Pros:

  • White TPO membranes reflect the solar energy of the sun; reducing A/C costs during hot summer months
  • Heat welded seams eliminate the use of adhesives or tapes, making it a very safe system to install
  • Typically, mechanically fastened which increases the installation time
  • Industry comparable warranties are provided and/or available
  • Resistant to many chemicals, making it a good choice for industrial applications

Cons:

  • TPO membranes are extremely slippery when wet and/or snow and ice covered; walk-pads must be used
  • Tying into a TPO roof after a year usually requires a chemical cleaner in order for it to become re-weldable
  • Becomes brittle and stiff over time; to the point that sometimes can’t be re-welded
  • TPO’s are stiffer than PVC and not as user-friendly when installing on cooler or cold days
  • The seams are ‘heated’ together and not melted/fused to the degree PVC membranes are, so seam failures occur if not performed by a highly skilled and experienced tradesperson

EPDM (ethylene propylene diene terpolymer)

EPDM (rubber roofing), is a flexible, stretchable, single ply roof membrane that is most commonly loose laid and ballasted with river rocks.  Goodmen Roofing is experienced in the installation and repair of EPDM roof systems.

Pros:

  • EPDM roofs can be installed in large, monolithic sheets that minimize laps and seams
  • EPDM is very flexible even in extreme cold temperatures
  • Easy installation makes EPDM one of the lowest cost flat roofs systems available
  • Best suited for larger buildings with little or no roof penetrations

Cons:

  • EPDM seams and detail work relies on tapes and adhesives that are highly sensitive to cold, hot, wet, wind, dust, etc during their application
  • A ballasted EPDM roof system weighs no less than 10 psf., therefore not suited for all building structures
  • EPDM is notorious for leaking at the detailing, but the low initial cost quite often overshadows that fact
  • Finding a leak is near impossible as the rock ballast must be removed first and is very labour intensive

BUR (tar & gravel / Built-Up Roof)

BUR roofs are a combination of asphalt impregnated organic felt paper, hot asphalt/tar and fibreboard with a pea gravel covering. Since the introduction of SBS, PVC, TPO and EPDM roof systems, BUR systems not the norm. Goodmen Roofing does not install this type of roof system.

Pros:

  • Other than used to repair and old BUR system, these roofs have little to no advantages over the new systems

Cons:

  • BUR used to be an inexpensive system, but the price of oil changed that several decades ago
  • BUR systems use tar kettles, torches which are notorious for catching fire during the application
  • Only a 3rd party will/can offer a warranty as the components of a BUR system are produced by several sources
  • Products used in today’s BUR systems are not the same quality they were several decades ago
  • The lifespan of a BUR system has been ‘estimated’ at approx. 10 years; less than half of it’s competitor’s

Asphalt Shingles

Asphalt shingles are by far the most commonly used sloped roof product there is. Asphalt shingles are comprised of asphalt blends (the quality differs between an entry level and a high-end shingle), a mat in which the asphalt is attached to (organic and more commonly inorganic felts) with coloured granules for UV protection and aesthetic appeal. Goodmen Roofing prefers to install only high-end asphalt shingles.

Pros:

  • Asphalt shingles remain the least expensive sloped roofing system available and offer the most colour choices
  • Recycled shingles are used for road repairs
  • Relatively easy to install

Cons:

  • Asphalt shingles can and are affected by the outdoor elements; wind, hail, UV and heavy rains
  • Life expectancy, although most often touted as ‘Lifetime’, asphalt shingles typically last 10-15 years in favourable weather conditions
  • Should never be walked on as the granules are rubbed off and they’re there to protect against the elements
  • Can be purchased at any hardware or lumber store, too often they’re installed by unskilled people and when installed improperly, are subject to premature failure.
  • Cause huge costs for insurance companies due to their poor resistance to high winds and hail

Composites

Composites are used as an upgrade to asphalt shingles on sloped roofs and are most commonly made from a combination of recycled plastics, wood fibres, epoxies, pigments, UV inhibitors and other manufacturers specific binding agents. Goodmen Roofing prefers to install quality products like composites so you never need to re-roof again.

Pros:

  • Most composites are made up in part of recycled materials; a win-win for us and the environment
  • Composites are highly resistant to extreme weather, making them ideal for our Canadian climate
  • There are literally dozens of colours, styles and looks available for almost any building design
  • When replaced with new materials, the old can be recycled again
  • Composite warranties vary, but most offer Limited Lifetime
  • Past performance has seen some composites exceed 35 years of performance

Cons:

  • Some composites look ‘cheap’ and don’t appeal to everyone
  • The initial cost can be anywhere from twice to four times that of asphalt singles
  • Composites can be very slippery even when dry, so it’s highly advised never to walk on them
  • Some composites (based on their composition) can fade and lose their aesthetic appeal
  • Some composites can also fade unevenly, taking on a ‘patchwork quilt’ look that’s undesirable
    • Snow and ice slides off easily and can be a concern for anyone/anything below (snow-guards can be installed, but they’re an added cost)

Rubber Shingles

Rubber shingles are made from new and recycled rubber (old tires for example), polymers, UV inhibitors and proprietary materials.  Goodmen Roofing prefers to install high quality rubber shingles (like Calgary’s own Euroshield) so you never need to re-roof again.

Pros:

  • Available in shingles, shake and slate profiles with complementing accessories
  • Rubber products are available in several colours that will suit most sloped roof applications and appeal
  • Virtually resistant to our Canadian climate, whether it’s hail, wind, rain, snow, ice or UV rays from the sun
  • Sloped rubber roofing products are installed very much like asphalt shingles, so they’re fairly easy to install
  • Only available to authorized installer, ensuring they remain an upgrade in look and overall performance
  • Keeps thousands of old tires out of our landfill sites; a win-win for us and the environment
  • Can be completely recycled after lifespan
  • Are designed and formulated to last 30+ years, but results to date may prove to exceed that by a decade or two

Cons:

  • Sloped rubber roofing products give off a ‘new tire’ odor that dissipates after a few months of exposure, but some find it offensive up until then
  • The installed cost of a rubber roof is approx. twice that of a high-end asphalt shingle (although the life cycle cost is lower, making the Con and Pro in the long term)
  • Like composites, snow and ice tend to slide off rather easy, making the area below subject to impact (snow-guards take care of this but at an additional cost)

"Hail Proof" roofing products - fact or fallacy?

“Hail Proof” roofing products – fact or fallacy?

This is a great question and one we get asked often. The answer is double-sided; yes and no.

Flat roofing membranes that are covered with gravel ballast or paving stones are indeed ‘hail proof’ because the hail can’t get to them.

Sloped roofing products such as composites and rubber tiles are as close to hail proof as you’ll find in the sloped roofing category. Cedar shakes, shingles and even quarry slate and concrete tiles can only take small to medium sized hail hits without sustaining damages.

Membranes with a granule surface such as SBS and asphalt shingles do not fair well in hail storms. Once the granules have been ‘beaten’ off of them, they’re susceptible to UV degradation and a much shorter life expectancy.

Single-ply membranes installed over a hard substrate such as cement board, plywood, steel or concrete tend to perform very well in hail storms (for example, strike a piece of paper laying on a cement floor with a hammer). Membranes installed on soft substrates such as foam insulation and fibreboard will take small and medium sized hail due to their modern manufacturing process and material composition, but larger hail will crack the surface and be subject to leaking if not addressed in a timely fashion.

Never assume weight bearing capacity

Compare the load bearing effect of different roof products

Flat roofing systems are not ‘one size fits all’ and/or in the same weight or load bearing capacity.

  • A ballasted roof is a minimum of 10# psf before you add in the insulation, intermediate layers of drywall, vapor barrier, substrate, etc.
  • A single ply membrane can weigh as little as .25# psf by itself before adding in the other components.
  • Sloped roofing products, such as concrete tile and quarry slate, are the heaviest products.
  • 28 gauge screw down metal roof comes in at one of the lightest.

So… ask your roofing contractor, an architect or an engineer before you decide what type of roofing is best suited for you and your building. Don’t ever assume weight loading capacities and/or design of a structure.

Are multiple layers better than one layer on a flat roof?

Are multiple layered roof membrane systems better than one layer on a flat roof?


It used to be that a 4 or 5 ply built-up tar and gravel roof system was the go-to for flat roofs. This was because the tar was installed very hot and flowed into every little crack and crevasse. In addition, the asphalt-impregnated felt paper used to give strength to a tar and gravel roof system, absorbed the hot asphalt and made a monolithic membrane.

Tar and gravel roofs have a vapour permanence and eventually absorb water. Another issue with tar and gravel roof systems is the poor quality of products available and the fact that very few contractors still install this dirty, smelly, dangerous and ‘old school’ system. Two-ply modified bitumen membranes more or less replaced tar and gravel roofs due to their ‘new age’ material combinations, design and manufacturing process.

Single ply membranes such as EPDM, PVC and TPO are the new ‘norm’ and are installed on the majority of flat roofs today. What will keep you drier? A roof system 1” thick or one that’s 40mil thick? The answer is both. A roof system should be chosen based on weight, the number of penetrations, ease of maintenance, proven field performance, the lifecycle cost and of course, an experienced roofing contractor with references to back them up; do your homework!
