Roof problems
Start from what you can actually see.
A roof problem is easier to plan once it has a name. Choose the description that fits closest — each guide explains what the sign implies, what you can check safely, what a repair usually involves, and what to ask before you spend anything.
Six common starting points
- Read the leak guide
Leak or ceiling stain
Water stains, drips and damp patches. Narrow down where water is actually entering, and what a repair usually involves.
- See what to check
Missing or damaged shingles
Lifted, cracked or missing tabs expose the layers underneath. What you can check from the ground, and when it stops being cosmetic.
- Open the metal guide
Metal roof concerns
Loose fasteners, seam separation, rub-through at fixings and ponding on standing-seam and exposed-fastener roofs.
- Open the flat roof guide
Flat roof concerns
Ponding water, seam separation, blisters and membrane wear on low-slope roofs, plus how patches are usually scoped.
- Storm damage guidance
Storm damage
Wind, hail and debris. What to document safely from the ground, and how to sequence temporary protection before repair.
- Repair or replace?
Repair or replace
The same spot failing for the third time? How to judge whether repair is still the sensible spend before you commit.
If the roof is unsafe right now
A sagging roof, structural movement, or water near electrical fittings is not a research problem. Keep people out of the affected area and contact a qualified professional or your local emergency services. We publish guidance only — we do not dispatch crews and cannot attend.
