There is a window every year between the last warm week and the first hard freeze. It is short, most people miss it, and it is the difference between a fifty dollar problem and a two thousand dollar one.
Roof problems do not announce themselves in October. They announce themselves in February, at two in the morning, as a stain spreading across a bedroom ceiling. By then the repair is harder, the weather is against you, and every roofer in the state is booked.
Here are seven things worth checking before winter sets in. Most take ten minutes. None of them require getting on the roof, and you should not.
1. Look for lifted, curled or missing shingles
Stand back from the house and look along each roof plane, ideally in low morning or evening light when shadows show up texture.
You are looking for shingles that have lifted at the edges, curled at the corners, or gone missing entirely. Also look for shingles that sit slightly darker than the ones around them, which usually means granule loss.
A few lifted tabs are a repair. A pattern of them across a whole slope, particularly along the rake edges, usually means the nailing was wrong from the start and wind has been working at it ever since.
2. Check the flashing, not just the shingles
Most roofs do not fail in the open field. They fail at the joints.
Look at where the roof meets a wall, around the chimney, and at any skylights. You are looking for metal that has lifted, pulled away, rusted, or has visible gaps where sealant has dried and cracked.
This matters more on the Seacoast than inland. Salt corrodes flashing and fasteners years before the shingles themselves wear out, which is why we check the metal first on coastal properties in Hampton and the surrounding towns.
3. Clear the gutters, properly
Not a quick scoop of leaves. Clear them and then run water through to confirm the downspouts actually drain.
A blocked gutter in November becomes a block of ice in January. That ice adds serious weight to the run, pulls hangers out of the fascia, and forces meltwater back up under the shingle edge instead of away from the house.
While you are there, look at where the water discharges. If it is dumping against the foundation, that is a separate problem worth fixing before the ground freezes. Undersized gutters are also worth addressing now rather than during a spring melt, and larger profiles carry considerably more water.
4. Go into the attic, which almost nobody does
This is the single most useful thing on the list and the one most homeowners skip.
Take a flashlight up on a dry day and look at the underside of the roof deck. You are looking for:
- Daylight visible between boards or at the eaves
- Dark staining or water tracks on the sheathing
- Insulation that feels damp or looks compressed
- Any smell of mildew
- Rusted nail points, which indicate condensation
The roof surface tells you one story. The attic tells you a different and usually more honest one. Staining on the sheathing means water has been getting in for a while, and decking that has taken on water will not dry back to structural condition.
5. Check that your ventilation actually works
Still in the attic, look at both ends of the system.
Ridge vent or roof vents at the top are the exhaust. Soffit vents along the eaves are the intake. Both have to be clear for either to work.
The most common problem we find is insulation that has been pushed into the soffit and blocked the intake completely. The homeowner has a ridge vent, assumes ventilation is handled, and has no idea that air is not moving at all.
That is what causes ice dams. Warm air collects under the roof, melts the snow above it, and the water runs down to the cold eave and freezes there. Fix the ventilation and you have addressed the cause rather than the symptom.
6. Cut back anything overhanging the roof
Branches over a roof cause three problems at once. They drop debris into the gutters, they hold moisture against the shingles and encourage moss, and under ice load they come down.
Late fall is the right time for this, once the leaves are off and you can see the structure of the tree clearly.
7. Deal with the thing you already know about
Most homeowners reading this already have something in mind. The stain that appeared last March. The section of gutter that has been sagging since spring. The shingles that came off in a storm and never got replaced.
Winter does not improve any of it. Water that got in once will get in again, and freeze thaw cycling turns a small opening into a larger one every time the temperature crosses freezing, which in New Hampshire is most nights between December and March.
A repair booked in October is scheduled work at a normal price. The same repair in February is an emergency call in bad conditions, and the damage inside the house has had four months to spread.
Why the timing matters more than people think
Roofing is seasonal, and not only because of weather.
Shingles need warmth to seal properly. The adhesive strip on an asphalt shingle bonds with heat, which is why late fall and winter installations often need hand sealing to hold until spring. It is doable, we do it, but it is more work and more expense than the same job done in September.
Contractor availability tightens too. Everyone who ignored a problem in October calls in January, and by then the schedule is full of emergencies that jump the queue.
The practical version: whatever you find on this list is cheaper and easier to deal with now than it will be in four months.
What we look at on a free inspection
If any of the above turned up something, or if you would rather someone who does this daily take a look, our free roof inspection covers twenty points across the roof surface and the attic.
You get photographs of anything we find and a written condition report, including our honest read on how many years the roof has left. There is no obligation attached to it, and if your roof is fine, that is what the report will say. A meaningful share of the roofs we inspect do not need work yet.
Frequently asked questions
When should I have my roof inspected in New Hampshire?
Fall is ideal, before the first hard freeze. It gives you time to schedule any repairs as planned work rather than an emergency. A spring inspection is also worthwhile after a hard winter, particularly if you had ice damming, so you can see what the season did.
Can I get roof work done in winter?
Yes, and we do it. Cold weather changes how shingles seal, so some work is staged: the roof is made watertight immediately and finish work is completed once temperatures allow. It costs more and takes longer than the same job in September, which is the argument for dealing with problems now.
How do I know if my attic ventilation is working?
Check both ends. There should be clear intake at the soffits along the eaves and clear exhaust at the ridge or through roof vents. If insulation is blocking the soffit vents, or if the attic feels warm and damp in winter, the system is not working regardless of what is installed on the roof.
Do gutter guards prevent ice dams?
No, and any product sold on that claim is overstating it. Ice dams are caused by heat escaping into the attic, melting snow on the roof, and that water refreezing at the cold eave. Gutters are simply where the ice becomes visible. Guards reduce cleaning and keep downspouts clear, which is useful, but the actual fix is insulation and ventilation.
Want someone to take a proper look?
Our free roof inspection covers the roof and the attic, with photographs and a written report you keep. Booked in the fall, most repairs are straightforward scheduled work. Left until February, they rarely are.
