Island storm season brings wind-driven rain, saturated conditions, and the occasional freeze. Roofs that sail through it are almost always the ones that were prepared in advance. Here is a practical, preservation-minded checklist for getting ready before the weather turns.
Clear gutters and downspouts first
Blocked gutters are the single most common cause of avoidable water damage in the wet season. When water cannot flow away, it backs up under the roof edge and pools against the foundation. Clearing gutters and flushing downspouts before the heavy rain arrives is the highest-value half-hour you can spend on your home.
Deal with moss before the rain, not after
Moss is at its most damaging when the roof stays wet for months. Addressing it ahead of the wet season — with proper low-pressure removal and treatment — means the roof goes into winter able to shed water rather than hold it.
Check the vulnerable points
Most leaks start at transitions: flashing around chimneys and skylights, valleys where two slopes meet, and any spot where a previous repair was made. A drone or ground-level inspection catches lifted shingles and failing seals while they are still cheap to fix.
Book the inspection before you need it
The worst time to discover a roof problem is during a storm. A pre-season assessment turns emergencies into planned, scheduled work — which is both cheaper and far less stressful. It is the same preservation principle that runs through everything we do: plan ahead, protect the asset.
Key takeaways
- Clear gutters and downspouts before the heavy rain.
- Treat moss ahead of the wet season so the roof can shed water.
- A pre-season inspection turns winter emergencies into planned work.
