Signs your roof is finished
Most roofs give you two or three years of warning. The trouble is that the warnings are easy to explain away one at a time.
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.
Daylight or damp in the attic
Go up on a bright day with the lights off. Pinpoints of daylight through the deck, dark staining on the sheathing, damp insulation or rust running down a nail shank all say water is getting in and has been for a while.
Repeated repairs in different places
One leak is an event. Three leaks in three different areas inside two years is a pattern, and the pattern means the covering has reached the end of its service life rather than suffered a specific failure.
Sagging along a line
A ridge or a plane that dips is a structural signal rather than a covering one. It usually means decking that has been wet long enough to lose strength, and occasionally framing. This is the one symptom that should not wait.
Shingles that curl, cup or go brittle
Look along the roof from the ground at a low angle rather than straight on. Edges that lift, corners that curl upward and a surface that no longer lies flat all mean the material has lost its flexibility. Brittle shingles crack when walked on, which is why contractors stop wanting to walk them.
The age on the paperwork
If the roof is over twenty years old and made of asphalt, an inspection is worth doing whether or not it is leaking. The failure modes above are much cheaper to catch before the water arrives than after.
Granules in the gutter
The granules are the sunscreen. Losing them in volume means the asphalt beneath is being cooked directly, and from that point the roof ages in years rather than decades.
In short
None of these on their own settles it. Two together usually do. An inspection costs little and removes the guesswork entirely.
Related questions
What should I do to prepare?
Clear the driveway, protect attic storage from falling dust, and plan for two loud days. Agree in advance where the dumpster goes and who sweeps for nails.
How many contractors will contact me?
Up to three. That is a hard cap, not a guideline. Three is enough to compare and few enough that your phone stays usable.
Do you cover the whole Los Angeles County area?
Yes. The contractors we match on cover San Dimas and the surrounding towns, so if you are just outside the city limits it still works.
