Ready to Replace Your Roof? Here’s How to Get Started

Replacing your roof is a big job, and you want to do it right so that it lasts for years to come. That means addressing some important questions before getting started. What type of roof is compatible with your home’s exterior and style? What material is best suited to the weather conditions? How does cost affect your choice? This guide will help you understand the different types of roofing and the tools you’ll need to get the job done right.

Types of Roofing to Consider

Asphalt/fibreglass and metal are two of the most common materials used for roofing. Find out the characteristics of each to decide which is best for your home.

Popular and Affordable Asphalt/Fibreglass Shingles

Asphalt shingles are the most popular type of roofing material. They are readily available, offer great value and, with some experience, can be installed as a DIY job. Asphalt-impregnated fibreglass-base shingles feature a man-made fibreglass core sandwiched between layers of asphalt.

Strong and Resistant Metal Roofing

Metal roofing is available in the form of panels or metal shingles. It is light, durable, fire-safe and requires minimal maintenance. Steel and aluminum are the most popular choices.

Metal roofing is:

Durable, long-lasting and low maintenance
Resistant to fire, insects, rot and mildew
Ideal for winter climates because it easily sheds water and snow
Environmentally-friendly because it contains recycled materials
Energy-efficient because it reflects heat and may qualify for tax credits
Versatile as it can mimic the textural look of wood, clay, slate and more
Clean and modern in appearance

TIP: Also take into consideration the slope (also expressed as the pitch) of your roof. The steepness of a roof can impact the cost and type of roofing material used. Low- or flat-pitched roofs must be topped with seamless materials to prevent water-pooling that can result in a leaking roof.

Synthetic Underlayment: A water-resistant or waterproof weather barrier installed directly onto the roof deck that works as an ice and water shield.

It can be left exposed before shingling over which helps during installation when adverse weather is encountered
Lighter than felt underlay, therefore it adds less weight to the roof
Tear resistant, wrinkle-free and resistant to fungal growth

Felt Underlayment: An older type of roof underlayment. It is water resistant but not waterproof.

Low-cost and easy-to-install material
Comes in two thicknesses: 15-pound and 30-pound
Over time, volatile compounds will dissipate, and it can become more moisture-absorbent and fragile

Roofing Nails: Commonly used for installing shingles, fastening underlayment and attaching roof flashing. They come in different sizes and materials suited to different roof types.

Flashing/Drip Edging: Flashing and drip edging are metal sheets that direct water away to extend the life of your roof.

Flashing directs water away from critical areas such as vents and chimneys
Drip Edging directs water away from the fascia and into the gutter, and can help give your roof a finished look

TIPS: Before you purchase your roofing material, determine how much you need:

Roofing materials are sold in "squares": 100 sq. ft. = 1 square in roofing terms
You can measure in square feet and have store staff do the calculation for you
A typical bundle of shingles covers 32 sq. ft., which is equal to one sheet of roof sheathing (plywood)
Add on 10-15% extra material to allow for waste

Accessories for Complete, Trouble-Free Roof Replacement

Make sure you include all the accessories you’ll need when creating a budget for your roof replacement costs. Here’s a quick rundown.

Eavestroughs: These are installed along the edge of a roof to collect rain. They help to protect walls from mould and rot.

Roof Vents: Roof vents assist with air ventilation in your attic, which in turn helps to regulate temperature throughout the home. They also regulate condensation, which helps prolong the life of your shingles.

Sealants: Act as a protective barrier to extend the life of your roof.

Roof Heat Cables: Heat cables help to prevent snow and ice buildup. They heat the roof, melting snow and ice that can become heavy, cause damage or fall and cause injury.

Roof Repairs

Does your roof just need a little TLC? You can also use the materials and accessories above to make roof repairs, or to replace individual components when a full roof replacement isn’t required.

Safety Tip: Replacing or repairing your roof involves handling rough materials. Be sure to wear safety gloves and safety glasses throughout the process.
