Serving Unionville, Cornell, Milliken, Thornhill (Markham side), and every neighbourhood across Markham with expert roofing, insulation, and aluminum work.
Markham is one of the GTA's most diverse and densely built communities, with homes ranging from the heritage streetscapes of Old Unionville to the large newer subdivisions of Cornell and the dense housing of Milliken. This variety means roofing needs vary enormously — and experience across all types of residential construction is essential. Ultimate Home Services brings that experience to every Markham job, backed by a proven track record and a team based just 15 minutes away in Thornhill.
Markham homeowners have found us consistently through HomeStars, where our perfect 5.0/5 rating and 118 reviews tell the story of a company that shows up, does the work properly, and stands behind it with a 15-year workmanship warranty.
Markham's 1980s–2000s building boom means a large proportion of the city's homes are at or past the typical shingle lifespan. We handle full replacements as well as targeted repairs for homes that just need isolated flashing work or missing shingles addressed. Every replacement includes tear-off down to the deck, thorough inspection, ice & water shield at all critical points, synthetic underlayment, and quality architectural shingles. We're efficient — most Markham homes are completed in a single day.
Markham's winters are cold and the city's flat topography doesn't provide much natural shelter from northerly winds. Homes in Cornell and newer subdivisions east of Highway 48 are particularly exposed. We install cellulose blown-in insulation to R-50 across your entire attic floor, eliminating cold spots and dramatically reducing heat loss. Homeowners typically see 15–25% reductions in heating costs after insulation upgrades — a return that pays back the investment within a few years.
Markham's mix of older and newer construction means some homes have original wood soffit and fascia that's quietly failing, while others have 20-year-old builder aluminum that's faded, dented, and pulling away. Either way, we replace it with durable, colour-matched aluminum that requires zero maintenance. Our seamless eavestrough systems handle Markham's spring runoff and summer downpours without the joint failures common in sectional gutter installations.
Markham sits in a part of York Region that sees the full brunt of GTA storm seasons. The open, flat terrain east of Yonge Street accelerates wind during summer thunderstorms — and high-wind shingle damage is more common here than in more sheltered western parts of the GTA. If you've noticed shingles lifting after wind events, it's worth having us take a look before the next rainstorm finds those gaps.
The Unionville area, with its mature trees and older homes, presents different challenges — moss and algae growth on north-facing slopes, aging flashing around dormers, and in some cases, original 1970s shingles that have been layered over rather than replaced. We always inspect for prior layers during our assessments and provide honest recommendations.
Just 15 minutes from Thornhill — we can typically schedule Markham assessments within 1–2 business days. No sales pressure, just honest answers.
