Roofing in Gloucester

It scales with roof area, pitch, number of storeys, access, and material. Basic asphalt shingle or concrete tile sits at the bottom of the range; metal, slate and clay cost two to four times more. Tear-off of the old covering, disposal, scaffolding or edge protection, and hidden deck repairs are the lines that move a quote most — make sure all four are priced before comparing.

Repair when damage is localised — a few slipped tiles, one flashing leak — and the roof is under about two-thirds of its expected life. Replace when leaks recur in different places, more than roughly 30% of the covering is failing, or repair quotes start approaching a third of replacement cost. A good roofer will show you photos from the roof to justify either answer.

Typical service lives: asphalt shingles 15-30 years, concrete tile 40-60, clay tile and slate 60-100+, metal 40-70, flat membranes (felt, EPDM, TPO) 15-30. Underlayment and flashings usually fail before the covering itself, which is why old roofs leak even with intact tiles.

A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.

A typical asphalt shingle replacement runs CAD $8,000-$25,000 with most homes landing around $12,000-$15,000; metal roofs run $18,000-$50,000. Per-square-foot pricing of $5-$13 installed is typical for asphalt.

It's possible but not ideal — shingle adhesive strips need warmth to seal, and snow slows and endangers crews. Most contractors work April-November; winter work is usually limited to emergency repairs and ice-dam mitigation.
