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
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.
705 Roofing installs trusted roofing products from leading manufacturers, including:
We are proud to be an Owens Corning Preferred Contractor, a member of the program since 2019.
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:
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.
Every roof is priced on its own, and a fair quote explains what drives the number. The main factors are:
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.
Laying new shingles over old ones costs less up front, because there is no tear-off. The trade-offs are real:
705 Roofing does full tear-offs on every replacement, so the deck is inspected and the whole system goes on new.
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.
A roof replacement is loud and busy, but you do not have to leave home. A typical job goes like this:
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.
In 2026 we replaced roofs in Wasaga Beach, Stayner, Barrie, Springwater, Essa and Grey Highlands. Most were full tear-offs on houses. Some were smaller jobs: one side of a house in Stayner, the rear slopes of a house in Wasaga Beach, and a detached garage in Wasaga Beach.
Most of our shingle roofs use Owens Corning TruDefinition Duration shingles. As an Owens Corning Preferred Contractor since 2019, we can offer Owens Corning System Protection when the whole roof is a new Owens Corning roofing system, and it is usually included in our price. Partial re-roofs do not qualify. A full new shingle or metal roof also gets our 10-year workmanship warranty.
A re-roof is often more than new shingles. On this year’s jobs we also:
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.
