The maintenance that actually matters
Most of what shortens a roof is neglect of things that take twenty minutes: a blocked valley, a lifted flashing, a gutter full of grit.

Three questions, and up to three Diamond Bar contractors. Free either way.
You are on the list.
No provider in Diamond Bar is taking requests through this service yet. We are lining them up, and yours is kept until one can.
- Nobody gets your details yet. Your request stays with us and is not passed to any company.
- One email when someone can help. When a provider covering your area can take it on, we email you once and ask whether you want that company, by name, to contact you.
- Deleted after 90 days. If nobody can take it on, or you do not say yes, your contact details are deleted 90 days after your request.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
Nobody will call you about this request unless you say yes to a company by name.
Keep the penetrations honest
Pipe boots crack, sealant shrinks, and satellite mounts get screwed straight through the covering. Every penetration is a hole somebody decided to make watertight, and each is worth a look.
Look in the attic after heavy weather
Check after the first real weather of the season rather than at the end of it. A small stain found in autumn is a cheap repair; the same stain found in spring is not.
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.
Clear the gutters before the wet season
Blocked gutters back water up under the bottom course of shingles and rot the fascia behind them. This is the highest-value hour of maintenance there is, and here it wants doing before November through March.
Twice a year, from the ground
Walk the perimeter with binoculars if you have them. You are looking for missing or lifted material, dark patches, sagging lines, and anything growing where it should not be. Ten minutes, twice a year.
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.
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.
Related questions
How much deposit is normal?
Ten to thirty per cent is ordinary, and is often used to order material. A demand for full payment up front is a reason to walk away.
I rent. Can I use this?
Only the owner can approve roofing work. If you are renting, the fastest route is to send this to your landlord or property manager rather than gathering quotes nobody can act on.
It is leaking right now. What do I do?
Move what you can out of the way, put a bucket under it, and if there is a bulge in the ceiling put a small hole at its lowest point to let the water out in one place rather than bringing the whole panel down. Then mark your request as an emergency — those go out first.
