The maintenance that actually matters

Clear the gutters before the wet season

Gutters full of grit are not just a drainage problem — the grit is your roof, and its presence tells you something about how far along the covering is.

Look in the attic after heavy weather

The attic shows a leak long before the ceiling does. After any serious storm, take a torch up and look at the underside of the deck around penetrations and valleys.

Deal with growth properly

Moss and algae hold water against the surface. Treat and brush gently, or fit zinc or copper strip near the ridge. Never pressure wash an asphalt roof — it strips the granules and takes years off it in an afternoon.

Cut back anything touching the roof

Overhanging limbs cause three problems at once: abrasion, permanent shade that keeps a slope damp, and a highway for rodents into the attic.

Twice a year, from the ground

You do not need to be on the roof to find most problems. A slow lap of the house at a low angle finds nearly all of them.

Keep the penetrations honest

Rubber pipe boots are the single most common source of leaks on an otherwise sound roof, and they are cheap to replace before they fail.

In short

None of this is difficult and none of it is expensive. It is simply the difference between a roof that reaches its rated life and one that does not.
