Is It Time to Replace Your Roof?

You may need a new roof if you notice:

If you’re not sure whether you need a repair or full replacement, we’ll inspect it honestly and explain your options

Our Roof Replacement Process

1. Full Tear–Off

We remove the existing shingles so we can properly inspect the roof deck underneath.

 

2. Plywood Inspection 

Every good roof starts with solid plywood. If we find rotten, soft, or damaged decking, we replace it before installing the new roof  system. 

 

3. Ice & Water Protection

We install ice and water shield in key areas such as eaves, valleys, around penetrations, and other vulnerable spots.

 

4. Underlayment Installation

A quality synthetic underlayment is installed over the roof deck for an added layer of protection. 

 

5. New Shingle System

We install starter shingles, field shingles, hip and ridge caps, vents, flashings, and accessories to complete the roofing  system properly.

 

6. Cleanup & Final Inspection

We clean the property, remove debris, run magnets for nails, and complete a final inspection before the job is finished.

Asphalt Shingle Roof Replacement

Most homes in Simcoe County have an asphalt shingle roof, and most shingle roof replacements put asphalt shingles back on. The choice is between two kinds:

  • Three-tab shingles are flat, single-layer strips with cut-outs that make them look like separate tabs. They were the standard on older homes and are now less common.
  • Architectural (laminated) shingles are two layers bonded together, which gives a thicker shingle and a textured, shadowed look. Owens Corning Duration, the shingle line 705 Roofing installs, is an architectural shingle.

The shingles are only the top layer. A shingle roof replacement done properly is a system: ice and water shield at the eaves and valleys, underlayment over the rest of the deck, starter shingles along the edges, the field shingles, hip and ridge caps, vents and flashing. When those parts come from one maker’s system and a certified contractor installs them, the contractor can register the maker’s extended system warranty, which covers that maker’s components of the roof, not only the shingles.

What Sets the Price of a New Roof

Every roof is priced on its own, and a fair quote explains what drives the number. The main factors are:

  • Size and pitch. More roof area means more material and labour. A steep roof is slower and needs more safety equipment.
  • Layers to remove. Tearing off two old layers takes longer and fills more bins than one.
  • The deck. Rotten or soft plywood found after tear-off must be replaced before the new roof goes on.
  • Details. Valleys, dormers, chimneys, skylights and plumbing vents each need flashing and time.
  • Ventilation. Adding or correcting roof and soffit-intake ventilation adds parts but protects the new shingles.
  • The shingle line and the warranty level you choose.
  • Access. Tight lots, steep driveways and distance to the bin all affect the work.

A quote that skips the deck, the ice and water shield or the ventilation is cheaper on paper because it leaves out part of the roof.

Can You Shingle Over an Old Roof?

Laying new shingles over old ones costs less up front, because there is no tear-off. The trade-offs are real:

  • No one sees the deck. Rot, soft spots and old leak damage stay hidden under the new roof.
  • No new ice and water shield or flashing goes in at the eaves and valleys unless the old roof comes off there.
  • More weight on the roof, and new shingles laid over a lumpy old surface do not lie as flat.
  • Warranty limits. Owens Corning’s extended system warranties require a clean deck with all old roofing removed, so a roof-over does not qualify for them.

705 Roofing does full tear-offs on every replacement, so the deck is inspected and the whole system goes on new.

The Warranty on a New Roof

Every new shingle or metal roof 705 Roofing installs comes with a 10-year workmanship warranty at no extra cost. If a leak or problem comes from how the crew installed the roof, it is fixed at no cost for those 10 years, and the warranty transfers once if you sell your home. As an Owens Corning Preferred Contractor since 2019, 705 Roofing can also register Owens Corning’s extended system warranties on a new shingle roof. The levels and what each one covers are set out on the roofing warranty page.

What to Expect on the Day

A roof replacement is loud and busy, but you do not have to leave home. A typical job goes like this:

  1. Set-up. A bin is placed near the house, and tarps go over gardens, decks and the ground near the walls.
  2. Tear-off. The old shingles and underlayment come off one section at a time, so the deck is never left open to rain longer than needed.
  3. Deck check and repair. Soft or rotten plywood is cut out and replaced. See roof plywood replacement for how that part works.
  4. The new system. Ice and water shield, underlayment, starter, shingles, flashing, vents and ridge caps go on in order.
  5. Clean-up. Debris is cleared, magnets are run over the lawn and driveway for nails, and the roof gets a final inspection.

Before the crew arrives, move cars out of the driveway, take fragile items off walls inside (hammering can shake them), and cover things stored in the attic, because some dust falls through during tear-off.

Roof Replacement Questions

What is the cheapest way to replace a roof?

Laying new shingles over the old ones is the lowest up-front price, but it hides the deck, skips new ice and water shield, and does not qualify for the shingle maker’s extended system warranty. A full tear-off with only the deck repairs the roof actually needs is the lowest cost over the life of the roof.

Damage in one place, such as one leak or a patch of missing shingles, can usually be repaired. Shingles curling or losing granules across most of the roof, leaks in more than one place, or a roof near the end of its life point to a replacement. If you are unsure, see our page on roof repair and ask for an honest look at both options.

Only where it needs it. After tear-off, the deck is checked, and soft, rotten or damaged boards are replaced before the new roof goes on. Sound plywood stays.

Yes, with care. Shingles seal to each other with heat from the sun, so in cold weather they may not seal until a warm day. For that reason, shingle makers’ instructions call for extra hand-sealing with roofing cement along the edges when shingles go on in the cold. Very cold, icy or wet days are not safe for a tear-off.

The 705 Roofing 10-year workmanship warranty transfers once to the new owner. An Owens Corning system warranty can also transfer; Owens Corning charges a transfer fee.
