Deciding whether it's time to replace the roof
Repeated leaks, widespread wear and several failing details can justify a replacement assessment. Roof age provides useful background, but it shouldn't be the only reason to recommend a new roof. The condition of the covering, supporting deck and connections matters more than a date on its own.
We review the existing roof and discuss whether replacement addresses a broader problem that isolated repairs would leave behind. When the roof remains serviceable apart from one area, roof repair options may be the more appropriate place to start.
Look beyond the surface material
A useful replacement proposal should explain which parts of the existing roof will be removed, retained or renewed. Two estimates can name the same roof covering and still describe very different work.
Removal and deck review
Our replacement service includes removal of ageing roofing and review of the deck during tear-off. The deck is the supporting surface beneath the roof covering. Its condition affects what can be installed above it.
Not every concealed condition is visible beforehand. Before work starts, discuss how unexpected deck damage or other hidden issues would be assessed, priced and approved. The estimate should make clear what is included and how additional work would be handled.
Underlayment, flashing and transitions
The layers beneath the covering and the details around walls, valleys, vents and skylights are part of the roof system. A replacement scope should identify which of these details need renewal and how the new roofing will meet any sections that remain.
This is especially important where the building has more than one roof type. A new sloped roof and an adjoining low-slope section need a considered connection, not two unrelated material choices.
Ventilation and drainage
Where the roof assembly uses ventilation, its condition belongs in the review. Drainage also needs attention, including the route water takes off each roof area. These questions should be addressed for the actual building rather than reduced to a standard list of extras.
Choosing the replacement system
Roof slope, shape, exposure, appearance and budget all belong in the material discussion. Asphalt shingle systems and metal roofing systems offer different finishes and detailing requirements. Flat and low-slope roofing needs a system suited to that roof area.
Start with what the building needs, then compare the available options. A preferred colour or profile is worth discussing, but it doesn't replace checking whether the system is suitable for the roof.
Planning the work around your property
Share access restrictions, other scheduled exterior work and any roof sections that have been replaced separately. Ask how material delivery, removal, temporary weather protection and final cleanup will be included in the project plan.
The building's height, roof complexity, removal requirements and concealed conditions can affect the scope and schedule. A useful estimate explains the work behind the price. A fixed online figure can't account for those differences.
If an older skylight is already being considered for replacement, raise it early. Discussing skylight replacement alongside the roof allows the two scopes to be planned together.
Roof replacement questions
Does re-roofing mean laying new material over the old roof?
Not automatically. The term can describe different approaches. Our roof replacement service includes removal and replacement, and the proposal should identify the intended method. Don't assume that retaining an existing layer is suitable or included.
Will every flashing and vent be replaced?
That should be stated in the estimate. Ask which components will be renewed, which may remain and why. A description that only names the roof covering doesn't tell you enough about those details.
How much will my replacement cost?
The roof area is only part of the scope. Access, geometry, materials, tear-off, flashing, skylights and deck repairs can also affect the work. Request an assessment and compare proposals on the same included items rather than the final number alone.
Do I need to choose the material before getting in touch?
No. Describe the current roof, known problems and the appearance you're considering. We can discuss appropriate system options as part of planning the replacement.
