Gauthier’s Windsor Roofing FAQ

How can I tell if I need a new roof for my Windsor, ON home?

If asphalt shingles were installed 10 to 15 years ago, especially given some of the inferior options available at that time, your roof might be ready for replacement. Some of the warning signs to look for with an asphalt shingle roof are excessive granule loss, curling, cupping, cracked or missing shingles. Signs of interior water damage can also raise a red flag. Sometimes the roof just visually looks old and worn, especially in the valleys. If you live in a neighbourhood where many of the homes have roofs of similar ages, and you’ve noticed that a number of these neighbours have replaced their roofs, then it’s time to take a close look. If unsure if you need a new roof, you can also reach out to a professional roofing contractor.

How much does a new roof cost?

There are several factors involved in the cost of a new roof. The main ones are the material selected, the scope of work, the size/style of the roof and the roofing contractor. A good shingle, as part of a complete roof system, installed by a reputable roofing contractor that has proper insurance coverage, provides a warranty, and an invoice will cost more than the alternatives. Keep in mind that roofing isn’t unlike anything else, in that you get what you pay for. For the majority of homes in the Windsor area, installing a new roof with fibreglass-based laminate style asphalt shingles, along with the rest of the components in the roofing system, by a reputable roofing contractor costs between $4500 and $9500.

How long will it take to replace my Windsor, ON roof?

Most shingle roofs can be replaced in a day or two, but large and/or steep roofs can take more time. A professional Windsor roofing contractor will make sure your roof is protected at the end of each workday so that in the event of rain before the next day, your home is protected. Sometimes some factors can add to the time it takes, like rotten wood replacement, weather delays or even how cooperative the old roof is when being removed. Sometimes an old roof peels off nicely in sections and other times, it can be very dry and brittle, breaking into little pieces. It’s essential to put the focus on craftsmanship as opposed to speed.

How long will a new shingle roof last?

This depends on several factors, mainly the material used, the roof’s design (ex. steep vs. shallow pitch), whether a roof system approach is used if regular maintenance is performed, and the quality of the installation. Weather patterns, as well as how much damage the sun will cause moving forward, are also factors. If an excellent fiberglass-based laminate style asphalt shingle is used as part of a complete roof system (i.e. full underlayment, proper ventilation, coordinated accessories, etc.), then maximum longevity can be achieved. From what we’ve seen in the Windsor area, 20-25 years have been achievable. Time will tell if they can last longer, but realistically not much more would be anticipated. As a side-note, for the price point in relation to other roofing materials (ex. metal, wood, rubber, clay tile, slate, etc.) it’s hard to beat the value of asphalt shingles. Other roofing material options may last twice as long, but they typically cost at least twice as much.

How do fiberglass shingles compare to asphalt shingles?

This is a common question, but it stems from a misconception. Fiberglass shingles are still asphalt shingles. Organic-based asphalt shingles were popular in the past, and these were typically referred to as asphalt shingles. When fiberglass-based asphalt shingles came out, they were usually referred to as fibreglass shingles, giving the impression that one was asphalt and the other fiberglass. In reality, both are asphalt shingles with the difference being the base of the shingle, one being an organic mat (i.e. paper) and the other being a fiberglass mat. Each of these mats (AKA bases), would be saturated in asphalt in the production process. It’s important to note that the organic-based shingles are no longer being manufactured, as their longevity paled in comparison to the fiberglass-based shingles, sometimes lasting less than ten years.
