Materials
Check and clear the deck drains
Every year, in October.
What to do
Clear the drains and scuppers on a membrane deck, and pour a bucket through to see it go.
Why it matters
A membrane deck over living space is a roof, and a roof with a blocked drain is a pond. The membrane is designed to be wet and not to be submerged, and the drain flange is the weakest point in it.
What to look for
- Leaves, needles or grit over the drain grate
- Water standing anywhere on the deck an hour after rain
- A scupper or downspout that runs slowly or not at all
- Sealant lifting where the drain meets the membrane — this is the joint that leaks
- Staining on the ceiling of whatever is underneath
Where this comes from
Travelers Canada New Home Maintenance Manual, Appendix G, "Check/clean deck drains" (section 6.15). October, after leaf drop and before anything freezes standing on the deck.
Catch it while it’s still maintenance.
