Preparing a Roof for Winter: Checks Before the First Gales

Preparing a roof for winter means clearing the drainage path and testing the details that wind attacks first, in the weeks before the first sustained gales rather than after them. Download the schedule for the roof and book a survey when a step needs a ladder. Clearing gutters before checking the ridge is the wrong order — dislodged debris from ridge and moss work lands in the gutters.

The autumn check runs top down, because everything dislodged higher up lands lower down. Leaf fall and the first sustained gales overlap by only a few weeks in the West Midlands, and the work sits inside that.

One thing to do before any of it

Cut the branches back Overhanging growth is reduced before leaf fall, which cuts both the debris and the shading.

Gutter clearance is the task with the most riding on it, because leaf fall coincides with rising rainfall — and it is still sixth, because what comes off the ridge lands in the channel. A preventative visit costs a fraction of a winter call-out and the internal drying that follows one.

What should you check before winter?

Clear the gutters and downpipes, inspect the ridge line for loose units, check verge pointing and every flashing, look for slipped coverings on all elevations, clear valleys and flat roof outlets, and cut back overhanging branches.

The winter preparation is carried out in early autumn, before the first sustained gales; the first task, because leaf fall coincides with rising rainfall.
The check of the ridge line is units sitting proud, missing mortar, vegetation rooted in the joint.
The verge is cracked or missing pointing at the gable edge.

When should the checks be done?

Carry out the checks in early autumn, after the bulk of leaf fall and before the first sustained gales. That window is short in the West Midlands, and a check completed after the first storm has already missed its purpose.

The flashing is cracked fillets and lifted sheet at every abutment; the check of the slipped unit is any displaced covering visible from ground level on every elevation.

What can you check from inside?

From inside the roof void, look for daylight through the covering, damp staining on rafters and underlay, insulation pushed into the eaves blocking airflow, and any sign of nesting. All four are visible without a ladder outside.

The valley is debris accumulation where two slopes meet.
Cut back before leaf fall to reduce both debris and shading.

Which faults cause winter emergencies?

Four faults account for most winter call-outs: loose ridge units lifted by wind, blocked gutters overflowing onto walls, cracked flashings admitting driven rain, and slipped coverings exposing the underlay to sustained weather.

The flat roof outlet is cleared of silt and debris, and confirmed draining.
A preventative visit costs a fraction of an emergency call-out and its internal damage.

An autumn leaf fall coincides with rising rainfall and blocks a drainage.

Is a preventative check worth the cost?

Yes. An autumn inspection and clearance costs a fraction of a winter emergency call-out, and avoids the internal drying and redecoration that follows water reaching a ceiling. The saving sits indoors, not on the roof.

An unbonded ridge unit is removed by the first sustained gale.
A blocked eaves stops airflow and produces winter condensation.
A preventative check costs less than the emergency it avoids.

Some checks need a ladder, and a ladder needs a reason.

What to leave to a roofer

Clearing gutters before checking the ridge is the wrong order — dislodged debris from ridge and moss work lands in the gutters. Leaf fall and the first gales overlap by only a few weeks in the West Midlands, and the check has to sit inside that.

Booking an autumn check

Daylight, damp staining and blocked eaves are all visible from inside, in ten minutes, with no ladder. A preventative visit against a winter emergency call-out plus internal drying and redecoration — the arithmetic is rarely published.
