5 Reasons to Hire Roofing Contractors For Repairs

A roof is a critical part of any home. It keeps the weather elements out and helps protect your family and belongings from damage. That’s why it’s so important to make sure that your roof is in good condition, and that means hiring roofing contractors for repairs when necessary. Here are five reasons why you should hire a professional roofing contractor for your roof repair.

1. Roofing Experience and Expertise

Roofing contractors have the experience and expertise to properly assess the damage to your roof and make the necessary repairs. They will also be able to recommend the best course of action to take to prevent further damage from occurring.

2. Safety

One of the most important reasons to hire a roofing contractor for repairs is for safety reasons. Working on a roof can be dangerous, and it’s important to have someone who knows what they’re doing when it comes to making repairs. A professional roofing contractor will have the necessary safety equipment and training to safely repair your roof.

3. Quality Roof Materials

When you hire a roofing contractor for repairs, you can be confident that they will use high-quality materials to make the repairs. This will help to ensure that your roof lasts for many years to come.

4. Roof Repair Warranties

When you hire a roofing contractor, they will often offer warranties on their workmanship and materials. This can give you peace of mind in knowing that if something goes wrong with the repairs, you’re covered.

5. Save Time and Get a Quality Repair

Hiring a roofing contractor to make repairs can actually save you time and money in the long run. They will be able to quickly assess the damage and make the necessary repairs, which can save you from having to do more extensive (and expensive) repairs down the road.

When it comes to roof repair, hiring a professional roofing contractor is always the best course of action. They have the experience and expertise to properly assess the damage and make the necessary repairs. Hiring a roofing company with experienced and a warranty is very important.

How To Find Roof Leaks

Your roof is essential to the protection of your home. A leaky roof can cause a lot of damage, so it’s important to find and fix any leaks as soon as possible. Water stains that cover ceilings or trickle down walls are likely the result of a leaking roof. In this post, we will teach you how to find roof leaks and who to contact to repair them fast and effectively.

Look For Signs Of Water Damage

If you think you might have a leak, the first step is to check your attic. Look for any signs of water damage, such as stains on the ceiling or dripping water. Water pouring into your attic through your roof may be identified by following the water’s flow back from the brown patch on the ceiling or wall. Look for damp spots at the bottom of the roof deck starting in the attic near where the leak is visible on the ceiling. If you notice water damage on your walls or ceilings, there could be mold damage as well. Check for mold damage on the interior of your home, this can indicate a leak that has been there for awhile. If you see any evidence of a leak, it’s important to contact a roofing professional right away. They will be able to inspect your roof and determine the best course of action for repairs.

Check Your Roof Outside

Another way to check for leaks is to go outside on a rainy day and look for any water that’s pooled on your roof. If you see any areas where water is collecting, it’s likely that there’s a leak in that spot. You can also check for any roof damage on the exterior of the home.

Fixing A Roof Leak

Once you’ve found a roof leak, it’s important to have it fixed as soon as possible. Depending on the severity of the leak, you may be able to do some repairs yourself. However, if the leak is significant or if you’re unsure how to fix it, it’s always best to contact a roofing professional. They will be able to quickly and effectively repair your roof, ensuring that your home is safe and protected from further damage.

Can Ice Damage Your Roof? Eco-Friendly Ways to Get Rid of Ice Dams.

Have you lifted a large pot of water? Heavy, isn’t it? Now, imagine many gallons of frozen rain and snow dammed at the bottom portion of your roof. As this bank of ice grows, it creates many problems for your roof, shingles and attic. But don’t worry, ice dams can be fixed!

Armour Shield Roofing strongly discourages homeowners from going up and down ladders or doing repairs on their roofs. The accidents and fatalities sustained by untrained individuals are tragic and avoidable by calling a professional roofing contractor.


What are the consequences of an accumulating hump of ice at the bottom edge of your roof? 

  1. This barrier produced by frozen snow and ice prevents snow and rain from exiting correctly off your roof through the eaves and downspouts.
  2. The underside layer of melted ice has nowhere to go but down and toward the warm interior of your attic. 
  3. Like the oncoming stream of water approaching a beaver dam of sticks and logs, falling snow has no way to pass the dam of ice and snow to exit your roof. The snow becomes an even bigger block of very heavy ice, putting incredible strain on your eavestroughs, downspouts, lower shingles and roofing plywood.

Armour Shield Roofing cares very much about your roof. We take care of eavestrough cleaning and inspect your roof to prevent or repair ice damming. Please contact us below.


What causes the phenomenon called ice damming?

Your warm attic air heats the underside of the roof plywood, and the heat transfers upward through to the shingles that have snow laying on them. The snow melts, but mother nature wins and refreezes the roof moisture, filling the eavestroughs and downspouts with solid ice. 

The attic space transfers just enough heat to keep the lowest layer of ice melted, causing the plywood to rot and water to back up eventually under the shingles. The water turns to ice at night between the shingles, expands, and pushes the shingle layers apart. This cycle never corrects itself all winter and allows crevices between the shingles for water to leak down into the attic. 

The shingle damage is evident in shingle edges drying, becoming brittle, losing granules, and eventually blown-off shingles.

Without repairing the overall problem, this cycle continues all winter, year after year. 


What are the solutions to preventing ice dams before winter descends?

Your roof surface and attic space must remain at the same temperature. The upside to these remediations is less money is spent on your heating and cooling bills, which in turn rewards our environment.

You can achieve a neutral attic temperature in five ways:

1) Ventilate your roof to allow any warm attic air to escape.

Soffit vents, ridge vents, and roof vents should be part of your roof structure. 

Soffit vents are on the underside of your soffit (where your eavestroughs are attached). They draw in the cooler, lower air from the outdoors, which pushes the warmer attic air out through your ridge vent (a vent that runs the entire length of your roof along its top ridge) and individual roof vents. 

2) Seal your attic space from the heat of the lower floors of your home.

This means sealing the whole upper floor ceiling. Holes for lighting or venting must be well sealed with proper insulation, and recessed lighting must have air movement around their wired housing. Insulation and adequate taping around adequately sized individual boxes ensure the ventilation requirements for the lighting and the insulation requirements for the attic are met.

3) Ensure bathroom and laundry vents do not vent into your attic space.

All venting must go through walls or rigid venting that extends out of the top of the roof. Prevent the heat emanating from your vent pipe surfaces from transferring into your attic space by using foil-covered insulation sheathing made uniquely for this application.

4) All flashing must be correctly placed around the chimney, venting pipes, or skylights along with the use of their associated caulking.

The use of appropriate caulking, depending on the application of its use, whether for a chimney, skylight, or different flashing, is crucial with the use of flashing. 

5) Add the correct amount of insulation to your attic.

Make sure the outside soffit edges are left free, so the movement of cool air coming from your soffits pushes the warm air up and out through your roof vents.


Armour Shield Roofing suggests these quick fixes if there is no other option for now. However, ice dams must be addressed professionally to avoid accumulated damage.

Electrical coils are often attached to roofing down near the eavestroughs, and they also run through the eaves and downspouts.

A nylon casing filled with eco-friendly icemelt attached three feet up from your eves and allowed to hang down and into your eavestrough helps to melt the ice build-up, keeping roofing sections and portions of the eavestrough free. This promotes runoff. 

You should never tackle quick fixes that involve ladder climbing in the winter. Even though we can purchase a ladder, it does not mean we are impervious to climbing accidents, especially if we are not certified roofers. Slippery surfaces are hazardous, but winter slippery is an entirely different sort of dangerous

Armour Shield Roofing uses and promotes the use of an eco-friendly ice melt that protects plants, animals and our precious water system. 

Do not use salt or chloride-based products to work through the ice in the eavestroughs or on your sidewalks. 

  • Chloride-based icemelt products perform by drawing moisture from whatever they touch. However, this effect is highly damaging to living cells, whether skin, animal fur, insects, plants, shrubs, grasses, or trees. 
  • If allowed into waterways, these chloride-type products, although used in the past, have proved life-threatening to our fish and wildlife, reducing the oxygen in the water leading to extensive aquatic death.

How Long Does It Take to Replace a Roof?

How long does it take to replace a full or partial roof of shingles? The answer to the amount of time required for a roof repair is, it depends. Contrary to what others may say, Armour Shield Roofing of London ON does not advise that you replace just part of the roof if it is past its useful life.

Armour Shield Roofing strongly discourages homeowners from going up and down ladders or doing repairs on their roofs. The accidents and fatalities sustained by untrained individuals are tragic and avoidable by calling a professional roofing contractor.

The length of time needed to replace a whole roof of average size with an easy installation is approximately two to three days although you may see online suggestions that the length of time it takes for a roof replacement is one day. Truthfully, there is always something that changes a roofing job from easy to slightly more complex and that something will add either a short amount of time or a longer extent of time.

Armour Shield Roofing of London Ontario does not recommend thinking of your roofing job as a race; a quality job requires a realistic work schedule.


Can you replace just part of your roof?

We sincerely don’t recommend it. If your roof is past its useful life, it is better for you to have a whole roof of a consistent age than have a patchwork of repairs. It is easy to track a roof’s overall performance when all roof sections are of the same age.

It takes more billable hours to weave individual roof sections to those adjoining; ultimately the cost to replace partial roof sections does not make financial sense and allows other problems to remain hidden.

The exception is when damage (by a storm or tree) has occurred to a roof with a reasonable amount of roof life left, it makes financial sense to repair that portion. Venting, flashings, and eavestroughs are usually part of that roof repair.

What circumstances add work time to the replacement or repair of your roof shingles?

The larger your roof, the longer the time required to remove and replace the shingles:

The advantages of replacing the roof of a smaller home are lower overall costs to you. The price of your roof replacement is determined by its coverage. Although different methods are used by contractors to measure a roof, all measurements come out to the same result.

The more uniquely shaped and the greater number of roof sections on your home, the longer its repair or replacement will take:

Many of us love the look of unique and varied-shaped roof sections. Curved roofs, sections intersecting other sections; these details create custom work in the form of more intricately installed flashing, shingles, and vents. Additionally, numerous roof sections require more work time. All of this pushes your roof costs higher.

Difficult accessibility to the roof sections will add time to roofing work:

Closely spaced homes require more time for everything to access their roofs; heavy shingles, equipment, plywood sheets, and workers’ access are delayed and made more difficult. Similarly, large bushes and trees hinder the efficiency of the project and all of this extra time must be accounted for.

Steeply pitched roof sections are dangerous, and your roofing contractor must take more safety precautions:

Additional safety equipment must be installed on a steep roof, not only for the benefit of the crew but also to ensure the roofing supplies stay in place. The extra care that must be taken on steep roofs translates to a lot more time and effort.

Flat roofs or those with a shallow pitch require special attention:

If easy water run-off is unlikely, roofers must protect the roofing plywood with additional special underlayment.

Restoration projects to historically significant homes take much more time:

Special products are likely needed to replicate the roofing of your historical home. Its structure may be quite different from a contemporary home too. Even special permits may be required, depending on whether your home is on a local historical list.

Finding hidden problems as the project unfolds adds unavoidable further work:

Armour Shield understands there is often hidden damage and your project manager will discuss these possibilities at the outset and make sure you are kept informed every step of the way.

Excessive moisture in your attic is often caused by improper roof venting or/ and improperly applied attic insulation. This moisture causes the roofing plywood to soften, degrade and rot to the extent new plywood may be required as well as further venting.

Are There Any Roofing Projects I Can DIY? -3 Dangers to Consider

You might ask, ’How hard is it to install your own roof?’ There are several reasons that you should not try a DIY roof replacement. Unless you have previously worked as an employed roofer and have your roofing legs, you will be taking a substantial risk.

Armour Shield Roofing strongly discourages homeowners from going up and down ladders or doing repairs on their roofs. The accidents and fatalities sustained by untrained individuals are tragic and avoidable by calling a professional roofing contractor.

The 3 Dangers of DIY Roofing:

  • The number one reason to avoid doing your own roofing is your risk of falling and the incredible injuries that can result.
  • The number two reason to avoid doing your own roofing is your lack of proper, safety-regulated equipment that makes a roofer’s job easier and safer.
  • The number three reason to avoid doing your own roofing is a lack of roofing expertise and an understanding of secondary concerns.

This highly skilled job is best left to the professionals. It is because a roof appears simplistic, that so many DIYers are injured.

The following are just two incidents that happened to real people: A client sustained a debilitating brain injury from falling onto his concrete driveway due to a rotted facia board that upended the ladder, (not safely attached), on which he was climbing. Another client working overconfidently on his own roof, fell from his ladder and subsequently broke his heel. Approximately 12,000 people are injured annually from falling from a height. One-third of falls from roofs result in fatalities and unfortunately, a head injury is the third most common outcome. Statics from Ontario Occupational Health and Safety (OHS) show homeowners’ and workers’ falls from roofs are increasing.

Falls occur because fall-protection equipment is misused or is not used at all.

Not understanding job procedures, a lack of training and the use of shortcuts make up the second group of reasons that falls happen. A lack of edge awareness and poor lines of sight are common reasons for accidental falls from roofs. A damaged roof is a dangerous thing to navigate, even for experienced roofers. Like the rotted facia board that caused a client’s ladder to fall sideways, a structural weakness can begin to fail beneath you and give you little or no time to react. Tripping on vent pipes, snagging gear, a rope or a tool on something attached to the roof’s structure while on the roof, is always a risk. Slipping on a steep roof. Workers wear special safety roofing footwear; paramount to having firm footing. Not having roofing legs (experience). Roofs constructed with areas of different levels and variable heights, can cause sudden tripping or stumbling, especially when carrying a large piece of plywood as a gust of wind occurs.  

Many fall accidents happen, not while on the roof itself, but from climbing up or down the ladder.

Roofing employees are taught safe ladder and climbing techniques while accessing a roof. Special equipment is used to stabilize and tie off a ladder properly, crucial to avoiding an injury. Every employee is required to graduate from a government-approved working at heights training program, additionally, equipment-specific training is required. Roofing contractors take their profession very seriously. Roofers are trained to inspect the facia and roof even before their attempt to climb a ladder is made.

Curb appeal is a smart reason to make sure your roofing project is done by a professional.

There’s a reason that painting is one of the most common DIY projects for a homeowner to take on. It is because it seems easy. However, we still easily distinguish between a painting job done by someone who should never have picked up a roller or paintbrush and one by someone who has clearly perfected the task. Even if you feel you mastered heights, having taken heights safety classes, do-it-yourself roofing is very much about knowing what you’re doing. Shingles laid by a DIYer are very often easy to see. Laying shingles correctly as per manufacturers’ guidelines, and having the knowledge and experience to contend properly with typical or unforeseen roof problems, is essential. According to a May 12th, 2021 article written by Clayton DeKorne, Canadian Cost versus Value Report by ZONDA, roofing came in 12 out of 22 projects with the highest Return on Investment (ROI). 61% of your investment is returned. Keep in mind the time of its installation and the time of the home’s resale. Painting anything was not on the list.

You likely will not invest in, or have the storage for, the proper equipment that makes a roofer’s job easier and safety-regulated.

As an example, even the equipment and products required for painting is expensive to acquire; rollers, extension poles, ladders, good brushes and the price of quality paint are enough to turn people off DIY painting. The storage of painting equipment is sometimes reasonable if you have the space for it all. When it comes to roofer’s equipment, what on earth will you do with those items afterward: safety harnesses, hard hats, goggles, ladders, ladder hoist, tool belts, safety roofing-shoes, tin snips, tape measure, chalk line, nail gun, roof rakes, roof brooms, magnetic sweeper, tarps, roofing tools, plus the left-over underlayment, extra shingles, left-over felt paper, the old shingles and dumpster when the project is finished?
