The membrane, substrate, insulation and drainage need to work together. We plan your project around the complete assembly, with an explained work scope.
An ageing roof deserves a complete assessment before you decide on the work. Alliance Roofing helps you plan a flat or low-slope roof replacement around the condition of the roof, the needs of your building and your budget.
A ceiling stain does not always reveal where water entered. Planning an effective roof repair starts with understanding when the leak occurs and examining the relevant details. Describe the problem to Alliance Roofing so we can help identify the next step.
Is water entering your building? Call Alliance Roofing at 514 556-2864 to explain the situation and check availability. For an active problem, calling lets you share essential information without waiting for a website request to be reviewed.
Does water remain in certain areas of your roof? Drainage deserves attention alongside the rest of the roof assembly. Alliance Roofing can help you prepare an assessment of the affected areas and discuss potential work as part of your roofing project.
Want a clearer understanding of your roof before deciding what to do? An inspection helps document visible conditions and establish priorities. Alliance Roofing helps you approach maintenance, repairs and future roofing work with a more informed plan.
A commercial roofing project needs to account for the building and the people who use it. Alliance Roofing handles enquiries for flat and low-slope roof replacement with attention to the scope of work and the practical organization of the project.
A modified-bitumen roofing project starts with an assembly that suits the building. Compare system options, installation details and replacement scope before deciding.
Replacement is an opportunity to review insulation, slopes and moisture control. The assembly should be designed as a whole, rather than simply adding thickness.
Roof junctions deserve as much attention as the main surface. Plan an assessment of flashings, copings and penetrations for a coherent waterproofing system.
Accessible drains and outlets help with flat-roof maintenance. Debris, persistent water and overflows should be assessed to understand what is obstructing drainage.
