Common Roofing & Contractor Questions for MacKenzie Roofing

At MacKenzie Roofing we will not give you an estimate without going on your roof. Some roofers may give estimates sight unseen, but we want to be upfront and transparent with all of our costs and it is difficult to give a 100% accurate quote without seeing your roof in person. We have to take measurements, check out the area and see the condition of the roof, which we can’t do from far away. Sometimes there may be something wrong with your roof but we won’t be able to tell without inspecting in person. For a thorough and complete estimate, schedule an appointment so we can check out your roof today. You may have a lot of questions, if you don’t see your answer below, call us today.


How do I know if my roof needs replacing?

Visually inspect your roof from the outside. If you see any of the following you will want to have a professional roofing contractor inspect your roof:

  • Cracked, curled, warped or missing shingles
  • Gutters clogged with decomposing shingle granules
  • Corroded metal flashing
  • A bowed roof (which may indicate rotting wood trusses)
  • Rotting fascia and soffits (which may indicate decomposing roof shingles)

Inside your house, look for water damage in ceilings and walls. Don’t forget to look in closets and the attic. Water damage is often first seen around ceiling vents and light fixtures. Soft spots and discoloration in drywall, plaster or wallpaper may also indicate moisture inside the walls. Unseen interior damage behind walls may remain unseen for many months or years resulting in substantial damage and repair costs.


You may not want to wait until your roof gives you problems. After all, your roof protects everything you own. If your roof is over 15 years old it may be time to re-roof. The life of your roof is dependent on many factors including the quality of the original installation, the proximity to trees, regular inspection and maintenance of your roof, and the type of product originally installed. Keep an eye on the appearance of your roof or call a qualified roofing contractor to make a professional assessment.


What should I know about roof ventilation?

Your home needs to breathe and ventilation in your roof and attic system are an important part of a safe and healthy home. Our building code stipulates one vent for every 300 square feet of roof.


Moisture from everyday living (showers, laundry, dish washing and cooking) needs to escape from your house to prevent mold, mildew and the rotting of your attic wood.


Summer heat needs to escape so your home does not become unbearably hot. Winter heating also needs to escape from attic spaces to prevent ice damming. (Ice dams are the large mass of ice that collects on the lower edge of the roof or in the gutters. As more melting snow runs down the roof, it meets this mass of ice and backs up, sometimes under the shingles and into the attic or the house.)


An effective ventilation system will help:

  • Reduce attic heat build-up
  • Reduce attic moisture and condensation
  • Prevent weather infiltration (drifting snow, wind-driven rain)
  • Prevent ice dam build-up

What types of fiberglass/asphalt shingle products are available?

At Mackenzie Roofing, we know customers want choices about their roof. Many options are available and we are happy to explain and discuss the good, better and best shingle product options that meet your budget and personal preferences.


How long will it take?

Depending on the size and pitch of the roof; anywhere from 1 to 4 days.


How much longer does my existing roof have on it?

If you give us a call, we can schedule an appointment and have a look to determine the life expectancy it has on it.


How much maintenance is involved with a new roof compared to my old roof?

Both flat roofs and metal roofs are maintenance free. A tar and gravel roof requires more upkeep and usually requires re-roofing (contact us for details on these types of roofs). Shingled roofs require more discussion, so feel free to contact us for more details on these types of roofs.

What kind of questions should I ask a contractor?

How long have you been in business?

Where are you located?

Is your service 24 hours a day, 7 days a week?

Is your staff trained and licensed?

Do you have general liability insurance and workers compensation?

Do you have a business licence to work in this community?

Do you have any references?

What kind of record do you have with the Better Business Bureau in this community?

Are you willing to put all agreements in writing?

Do you provide a written warranty for materials and labour?


What should I do when I get estimates that are different in price?

Provide each company doing an estimate with the same specs. A low price can signal estimate discrepancies, unreliability, and inexperience on the contractor’s part. If you’re still not sure, you might need to call an inspection company to help determine the right specs for your roofing project.


Where can I find a reliable inspection company?

Inspection firms comply with Roofing Contractors Association Guarantee Corp standards, policies and procedures.


How much does it cost to get my roof inspected?

You can expect to pay between $300 and $400 for inspecting the roof of a typical home, depending on roof size and ease of access. For a strata or an apartment building, call an inspection company and get a quote.


I got estimates from two different roofing companies – one says I need to replace the roof and the other says I only need to repair it. What should I do?

It’s time to get an inspection done so that you can make an informed decision. This could save you thousands of dollars in the long run.


My roof leaks. Do I need a new one?

Not so fast – you may only need some repair work. Call a professional roofing company and get an assessment.


During which season is it best to replace my roof?

You’ll usually get better availability and faster service if you replace your roof in the spring or fall.


I have roof issues. I called a bunch of companies and no one has called me back. What’s the deal?

Most roofing companies are very busy during the summer. Give them a few days to get back to you. Don’t hesitate to call again.
