Shingle Roof Installation & Replacement

Protect your home and increase its value with help from an experienced shingle roofing company. First, we install engineered shingles with skilled craftsmanship and close attention to detail. In addition, industry-leading warranties help protect your investment. As a result, you receive lasting performance and the professional service your property deserves.

Is It Time To Replace or Repair Your Shingle Roof?

If your roof is 15 to 20 years old, inspect it for visible wear. Otherwise, delaying service may allow moisture to damage the roof deck. Over time, trapped moisture can also cause attic mould and costly interior damage. Therefore, contact an experienced shingle roofing company when you notice signs of deterioration.

Look for these critical warning signs:

Granules in Gutters: Accumulated granules in gutters or near downspouts may signal worn shingles. Therefore, contact a trusted shingle roofing company to inspect your roof’s UV and water protection.

Curling, Buckling or Blistered Shingles: Freeze-thaw cycles can cause shingles to lose their shape and effectiveness. Therefore, a shingle roofing company should inspect these warning signs.

Missing Shingles After High Winds: Wind gusts catching loose tabs indicate underlying adhesive failure or s shingle not designed to sustain high winds.

Water Stains on Ceilings: Water is penetrating the flashing or underlayment into your living spaces. This can cause extensive damage and mold.

Need an Immediate Assessment?

We provide honest evaluations. If a cost-effective repair can safely extend your roof’s lifespan, we’ll recommend it. However, if you need a full replacement, our shingle roofing company will clearly explain your options upfront.

Decking Inspection

Next, we thoroughly inspect your roof deck for rot or damaged plywood. If needed, we replace damaged sections before continuing. Then, we install heavy-duty synthetic underlayment for superior secondary leak protection.
