The roof condition checklist for Lower Mainland homes
What is on the list
Work through it from the ground or a stable ladder at the eaves. Never walk a wet, mossy, or steep roof — that is the one item on this page we would rather you left to us.
From the street
- Shingles or tiles that look lifted, shifted, cracked, or missing
- Sagging or wavy rooflines and ridges
- Dark streaking, heavy moss, or vegetation growing in the courses
- Metal edges, ridge caps, or vent hoods peeled back or rattling
Gutters and drainage
- Debris in gutters, valleys, and downspout outlets
- Water stains running down the fascia, a sign of past overflow
- Downspouts discharging against the foundation
- Standing water on a flat section 48 hours after rain
Flashings and penetrations
- Chimney, skylight, and wall flashings with lifted edges or failed sealant
- Plumbing stack boots that are cracked or hardened
- Silicone or caulking used as a repair, which is temporary at best
Inside and in the attic
- New or spreading ceiling and wall stains
- Musty smell in upper rooms or closets
- Damp sheathing, rusted nail tips, or frost in the attic
- Bathroom fans venting into the attic instead of through the roof

Checklist questions
Before you head outside
Do I need to get on the roof to use this checklist?
No. Every item is written to be checked from the ground, a window, or a stable ladder at the eaves. Walking a wet or mossy roof is how homeowners get hurt, and it can also damage brittle shingles.
How often should I run through it?
Twice a year works for most Lower Mainland homes — once in spring to see what winter did, and once in early fall before the rain settles in. Add a quick pass after any real windstorm.
What if I find something on the list?
Take dated photos and send them to us. Most findings are minor and can wait for a scheduled visit. Active water entry, missing shingles, or displaced flashing should be looked at right away.
Is the checklist useful for a strata or commercial building?
It is a useful starting record, but multi-building and low-slope roofs need drainage, membrane, and rooftop-equipment items a homeowner list does not cover. We put those together as part of a maintenance program.
