Is Your Roofing Solution in Shingles or Tabs?

Roofing Materials Today

Manufacturers make modern roofing from laminated compounds with color added. There are two basic types, which are essentially either a single-layer or a double-layer roofing tile. The double-layer roof tile is the architectural or dimensional type. The single layer is the three-tab version.

The architectural type is costlier but more appealing to the eye, and it can add value to your home. The single-layer type or three-tab tile is a basic roof cover. It has a flat appearance, and the tiles are consistent in size and shape.

Construction of Asphalt Roofing

The inner core of each tile is a piece of fiberglass. The fiberglass is water-resistant and provides some insulation. The maker then sandwiches the sheet of fiberglass between two weatherizing layers. Next, the top layer receives a covering of mineral granules, which add texture and color.

The architectural type of roof tile is a double of the four composite layers. The lower edge of the architectural tile has a raised laminated ridge. This raised section adds to the appearance of depth.

The double-layer composite tile is a popular roof cover. Manufacturers call it architectural or dimensional roofing. You can distinguish the architectural type from a three-tab or single-layer tile by its size, weight, durability, and appearance.

Asphalt Composition

Asphalt is the base material for architectural or double roofing and the 3-tab types. In the early 1980s, technical advances in lamination and materials created the architectural type. From that time to the present, architectural types have replaced tabs as the preferred material for roofing installations. Today, the traditional three-tab type of roofing is the low-cost option and the required material to repair roofs that already have tab shingles. 

When estimating the number of shingles needed to cover a roof area, Roofr uses technologically advanced methods to obtain precise measurements. Roofr will utilize satellite imagery to determine the exact roof dimensions and to estimate the bundles needed to complete the work on your home.

Advantages of Architectural Roof Covers 

The double-layer roofing tiles have a noticeable multidimensional surface. The tiles stand out for their contours and depth. You can get them in shapes and colors that resemble high-end materials, like baked tiles, cedar shakes, and slate tiles. The advantages of double-layer tiles include: 

  • Durability: Double-layer roofing lasts longer and maintains its appearance better than single-layer materials. While the costs of acquisition may be higher for double-layer roofing, the longer life and added value for your home can pay for the added investment.
  • Appearance: The double-thick roof types have the appearance of depth. They add value to homes because of their popularity and eye-catching results.
  • Wind resistance: The thick tiles do not resist the wind better than the thin tiles until they seal. Single-layer tiles traditionally have ratings of up to 80 miles per hour. The manufacturer's warranty requires a 6-nail installation pattern for a high-wind damage rating of up to 130 miles per hour.
  • Warranty: Manufacturers typically provide warranty coverage in the range of 40 to 50 years. The latest warranty trends also include a lifetime coverage for as long as you own your home.

Why Slope Matters in Roofing

Roof Slope and Project Estimates

Roof slope is one of the biggest factors that professionals consider when calculating a price for a roofing job. A steep roof may present a number of challenges. Generally, the steepness of a roof relates to how much risk is involved with the project, especially if it is on a tall building. Working on a roof with a steeper angle may also require bringing in more equipment and taking longer to deal with issues. All of this is factored into your roofing estimate.

The Ratios

The pitch of a roof is commonly expressed as a ratio or fraction. The rise is stated in inches of height per 12 inches of length. For example, a 4/12 grade on a roof means the surface rises 4 inches for every 12 inches of length.

This can lead to some misleading math. While 12/12 as a fraction sounds tame, it actually means that a roof rises very aggressively for every foot of distance. Conversely, a 1/12 grade is actually rather flat.

Conversion table:

Roof Pitch Angle Roof Pitch Multiplier
1/12 4.76° 1.0035
2/12 9.46° 1.0138
3/12 14.04° 1.0308
4/12 18.43° 1.0541
5/12 22.62° 1.0833
6/12 26.57° 1.1180
7/12 30.26° 1.1577
8/12 33.69° 1.2019
9/12 36.37° 1.2500
10/12 39.81° 1.3017
11/12 42.51° 1.3566
12/12 45.00° 1.4142

Calculating Pitch

One of the easiest and safest ways to calculate roof pitch is from inside your attic using a level, tape measure, and pencil. First, measure 12 inches on your level and make a mark. Then, hold the level flat against the bottom of a rafter while making sure the level bubble is centered between the two lines.

The final step is to measure vertically from the 12-inch mark on the level to the underside of the rafter above it. The distance from the level to the rafter shows you how much your roof rises for every 12 inches of length. This is a good rough figure that you’ll be able to pass along to a contractor.

At Roofr, we help customers connect with contractors quickly. Knowing the angle of a roof will enable you to provide better information as you receive multiple estimates through our system. Contact us today to start the Roofr process.

Let It Breathe: The Importance of Roofing Ventilation

Roofing Ventilation

Can your roof breathe properly? It may sound like a silly question, but the answer is critical to the health and long-term durability of your home. Whether you live in a hot and steamy climate or you prefer the colder weather of the northern latitudes, there are good reasons for making sure that your home has the proper roof ventilation. To help you better understand why these vents are so important and how to determine whether your home can adequately breathe, let's take a look at everything you need to know about roofing vents.

The Importance of Proper Airflow

When it comes to protecting your roof, and the home below it, it's all about controlling temperature and moisture. During hot weather, the sun beats down on your roof and transfers an extraordinary amount of solar energy, causing the air below to become extremely hot. This eventually works its way into your home, significantly increasing the need for cooling and creating a less pleasant living space. It also places a lot of stress on your roofing materials. In cold weather, the opposite problem occurs. Warm, heated air from inside your home transfers to the roof, melting snow and creating a risk of ice dams. This clash of warm air with a cold roof also causes moisture buildup, potentially posing a risk of mold growth and even water damage.

Let Your Roof Vent

The solution to both of these issues is simple: Increase the airflow around your roof deck and attic with proper venting. By creating a steady flow of air, you can ensure that your roof stays cool year-round. This means less stress on your roofing materials, less cooling costs during the warmer months, and less risk of ice dams and moisture buildup. In fact, proper airflow is so important that inadequate venting may even void any warranties offered by your roof's shingle manufacturer. So, how do you know whether your roof is vented correctly?

How Roofing Vents Work

At its most basic, venting a roof requires vents for air intake and exhaust. There are a number of options to choose from in each case, with intake vents including:

  • Soffit vents
  • Fascia vents
  • Dormer vents

There are even more options for exhausting air, such as:

  • Ridge vents
  • Gable vents
  • Turbine vents
  • Off-ridge vents
  • Powered attic vents

The Right Amount of Ventilation

Unfortunately, ensuring proper airflow from soffit to ridge isn't quite as simple as it sounds. The air needs to circulate smoothly and consistently to achieve the desired effect, and poorly placed vents can disrupt this airflow or even stop it altogether. Finding the right amount of ventilation is also important as both too much and too little airflow can potentially cause problems. Though the typical standard is the 1/150 rule, meaning that one square foot of free vent area is required for every 150 square feet of attic space, it's best to check with your local municipality for specific building codes.

As you can see, outfitting your roof with proper roofing vents is an important but complex task. If done correctly, it can help to lower your cooling costs and extend the life of your roofing materials for years to come. If you suspect that your roof may not have the venting it needs, or if you'd simply like an expert opinion, contact us today to begin the Roofr process. You'll be glad you did!

A Valley on My Roof? - Roofing Language Explained: Valleys

Valleys and Flashing explained in simple terms.

It may sound odd to learn that you have a valley on your roof. The place where two roof surfaces intersect is called a valley. This is one of the most common areas for a roof to leak. Non-permeable materials such as metal sheets or roof rolls are placed over these joins to seal out moisture.

Definition of a Roof Valley

The greatest portion of a roof is a flat expanse that is covered with a non-permeable material, such as asphalt shingles, metal tiles or slate tiles, to protect the roof structure and the interior of the building. When two roof surfaces meet, a valley is created. The valley creates a channel that allows moisture to run off the roof.

Importance of Flashing in Valleys

Water flows onto and down the metal flashing in the valley.

If your roofer says to put flashing in the valleys, the contractor is concerned that moisture may penetrate between joins. Flashing is placed in a valley to create an impermeable seal. Valleys often deteriorate more quickly than other portions of a roof, particularly if leaves and debris build up in the channel. If valleys become clogged, water will not run off. As debris accumulates, the flashing weakens and corrodes.

If your roof leaks, a roofing expert can inspect the roof surface and valleys to find the source. Roofr works with vetted roofing contractors who are licensed to work in your area. Each independent contractor provides a guarantee for labor and a warranty for materials. Roofr makes sure you're satisfied with the quality of work. Our goal is to hear you say, "My roofer did an excellent job. My roof looks great, the valleys are well-sealed and there are no problems."

Why Get a Roof Inspection or Consultation?

You might find yourself looking for a roof inspection or consultation. It is usually because there is a new problem appearing on your ceiling.

Finding the cause of the problem

Whether it’s a leak or missing shingles, a consultation will be necessary so that you know how much you will need to spend for your repair, as well as how long it will take to fix. But you don’t need to wait until you have a major roofing emergency; what a lot of people don’t realize is how much a bi-yearly roof inspection can help save you money, and potentially prevent major roofing emergencies. 

Preventative roof inspections

Just because there might not be an immediate or noticeable issue, doesn’t mean your roof is in perfect condition. By getting a regular inspection, you’ll be able to catch problems early on, which could save you possible thousands in the future. Often times, minor repairs don’t cost a lot and can really help with the longevity of your roof.

If you are looking to buy or sell a home, you should seriously consider a roof inspection or roofing consultation. It’s common for a roof inspection to be on the list of required inspections when selling a home, mostly because agents don’t want their new homeowners blindly walking into a house with huge repairs hanging over them. If you are looking into purchasing a home, and you see that they have not had the roof inspected, its advised that you ask for a consultation before you purchase the home. If you sign off on a house that is sitting at the higher end of your budget, and find out later on that you need to pay for the entire replacement of a roof, its going to quickly become a shocking and disappointing experience.

Finding the right roofer for your project

Consultations are a super important part of finding the perfect contractor for you. Without a consultation or some kind of initial meeting, you might as well be going into your homeowner/contractor relationship blind. Its important to find out if the contractor is a licensed professional, and to find out how much experience they have, especially if you have a very specific problem with your roof. You want to make sure that the person you hire can get the job done safely, professionally and in a timely manner.

And that’s where Roofr comes in; we simplify that process for you.

Roofr guarantees professional contractors, free estimates, amazing savings and a full warranty on all of our roofing systems. We’ve got all of this, and your home covered.

How Does Roofr Save You Money?

4 min read-

Roofr Vs. 'The Big Guys'

Since Roofr’s launch just a few months ago many people have asked how we can possibly save customers so much money, and do so without sacrificing the quality of both workmanship and material.  The answer is ingrained in the basic principal of who we are. We are ‘Roofing Simplified’.  After many years in the traditional roofing industry, we’ve witnessed the seemingly endless inefficiencies and subsequent costs of the standard roofing operation. We’ve decided to do our best to change that.

How do most roofing companies work?

Let’s start by talking about ‘the other guys’. Why are large roofing contractors charging an arm and a leg to get the job done?

When it comes down to it, big roofing contractors are essentially marketing giants; consisting of elaborate tiers and avenues to be navigated. When you, the homeowner, call up one of the big guys and ask for a quote, they proceed to send out a sales rep to convince you their high price point is necessary. 

They will then call up a guy who will probably call up another guy, who might just be the guy that installs your new roof.  Large scale roofing companies subcontract 100% of ‘their work’ and tack on an additional markup as high as 50%. 

That massive markup is necessary for these giants to survive.  It’ll cover over head costs, sales staff commission, marketing departments, accounting departments, project managers, and so on and so forth.  In the end you’re paying not only for your roof replacement, but for the big guys to keep the many archaic aspects of their business operational.

We connect you directly with reputable installers in your area

We eliminate the middleman and ensure that you receive competitive pricing on all materials.

No sales teams to pay commissions to, no advertising team or project managers, and most importantly no crazy overhead. Our revolutionary, stripped down platform has allowed us to save ourselves money in all areas.  We’re so pleased we get to pass those savings on to you.

We will never be the absolute cheapest roofer

We pledge to always provide the best possible workmanship and service at the most affordable price point.  At Roofr, we understand that you get what you pay for.  We know, and want you to know that we will never be the absolute cheapest choice

There are quite a few ‘fly-by-night’ roofing companies that often don’t have proper insurance, certifications, or WSIB clearance.  There can be no guarantee of the experience they provide or most importantly, the end result. Be wary of these companies; if it seems too good to be true, it probably is.

All of Roofr’s installation teams have been hand selected based on reviews, years in business, amount of jobs completed, insurance, certifications and overall workmanship.  You can rest easy knowing that your roof is in capable and reputable hands, and you didn’t have to spend that arm or leg to make it happen!

The Importance of Proper Roof Ventilation

2 min read

A properly ventilated roof can save you a ton of money in the long run. 

One of the most important components of a great roofing system is ventilation, the longevity of your roof greatly depends on it. A few extra dollars spent on adequate ventilation will save you a ton of money in the long run.

What does Ventilation do and Why is it Important?

Ice damning is a major cause of leaks during winter months. Ice damning occurs when your attic is not properly ventilated. Warm air from your home travels upwards and remains in your attic, melting the snow unevenly, which then freezes again when it reaches your eaves. This ice buildup will not only cause condensation and mould, but will deteriorate the shingles at a rapid rate and rot the roof deck.

During the summer, proper ventilation will allow for continuous outside airflow throughout the attic, keeping the inside of your home cooler, thusly saving you a large amount on your air-conditioning bill.

Things to Remember When Ventilating your Roof!

  • Your intake ventilation (soffits) must not be blocked by any insulation.
  • Vents must always be staggered along the ridge of the roof. Placing vents adjacent to one another will cause cross ventilation (air entering one vent and leaving directly out another).
  • Only one style of vent can be used in the same attic space. The use of different vents types will cause an imbalance in air flow and leave portions of the roof unventilated.

Ask your Contractor.

When replacing your roof, be sure to ask your contractor the following questions regarding ventilation:

  • Do I have an adequate amount of exhaust vents in relation to my attic space and intake vents?
  • Is there more than 1 type of exhaust vent being used on the roof?
  • Are my old vents being used?
  • Is there potential for cross ventilation to occur?
  • Are my intake vents (soffits) blocked by any insulation? (This can be checked by looking inside the attic space).
  • Do I have an adequate amount of intake ventilation?

All in all, choosing the right roofing contractor in your area will eliminate any future ventilation risks and save you a ton of money in the long run.

Hope this helps!!

How to Avoid Roofing Scams

Finding the right roofing company to repair your roof can be quite the hassle.

From filtering through the thousands of roofers online, not knowing who's best, to getting inconsistent quotes with massive markups. It can be really tough to make the right decision. On top of all this, there are a ton of shady, 'fly-by-night' contractors looking to scam you out of your hard-earned money.

In fact, problem's with home renovations are among the top consumer complaints in Ontario:

In 2015, the Ministry of Government and Consumer Services received approximately 1,600 complaints and inquiries about home renovation services – 21% were related to roofers.

-Consumer Protection Ontario

Roofing Project Checklist - What to Do:

We've compiled a quick checklist to help you avoid these scams and save as much money as possible.

  1. Get written quotes

    Make sure the following is in the contract:
    • The contractor’s business name, address and contact information
    • Detailed description of the work to be completed and the materials used
    • The total cost, including all applicable taxes, the payment terms as well as the down payment and deposit
    • How the property will be protected
    • Cleanup details
    • Who will cover any damages to your property in case of any accidents
    • Detailed warranty on both materials and workmanship
  2. Understand what you are signing for

    Ask the following questions:

    • How long will the shingles last?
    • Is there adequate ventilation?
    • Are you putting Ice & Water Shield along the perimeter, valleys, and skylights?
    • How much do you charge for plywood replacement?
    • Will you pull up the plywood to inspect for mold in the attic?
    • Will you magnet the property to pick up any missed nails?
    • Will you be using synthetic underlayment to cover the entire roof deck?
    • Will you be using drip edge flashings?

  3. Ask your contractor if they have the necessary safety training.

    Working at Heights Training is mandatory for any contractor using a ladder or working at any heights.

  4. Avoid any TAX-FREE deals. 

    This is extremely important. Not only does this raise many concerns why a business is trying to avoid taxes, but it also voids your warranty completely. If something happens to your roof within the warranty period, the shingle manufacturer will request a receipt for all materials and installation. If the contractor is providing you with a tax-free deal, they are most likely keep everything off the books and nothing will be documented. You will be on the hook for yet another expensive roof replacement.

  5. WSIB and Liability Insurance. 

    Make sure you ask for a recent WSIB Clearance Certificate and Proof of Liability Insurance (Minimum 1M)

If you're planning on repairing or replacing your roof this year, please take the time to vet the contractors, it could save you thousands of dollars down the road!

Hope this helps!
