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.
Get it looked at
Three questions, and up to three San Dimas contractors. Free either way.
You are on the list.
No provider in San Dimas 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.
Deal with growth properly
Cleaning a roof aggressively does more damage than the growth was doing. Gentle treatment, patience, and a strip at the ridge to stop it returning.
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.
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.
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.
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
Is moss on the roof a problem?
Yes, eventually. Moss holds water against the shingle and lifts the edges as it thickens. Zinc or copper strip at the ridge suppresses it. Pressure washing an asphalt roof strips the granules and does more harm than the moss did.
Is this really free?
Yes. You pay nothing, now or later. Roofing contractors pay us for the introduction, which is why the service costs you nothing and why we are upfront that it is how we make money.
I have solar panels. What happens to them?
Panels have to be detached and reset. Budget for it separately and coordinate the two trades. Never put a new solar array on a roof with under ten years left.
