What to check before you sign
The difference between a good roof and a bad one is mostly the crew, not the material. Both quotes list the same brand of shingle.
Get it looked at
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.
Compare scope, not totals
Lay the quotes side by side line by line. Underlayment type, ice-and-water coverage, drip edge, valley treatment, ventilation, flashing replacement, decking allowance and warranty. Large gaps in the total are almost always gaps in the scope.
Ask for current certificates of insurance
You want general liability and workers compensation, both current, and ideally sent directly from the insurer rather than as a photocopy. If an uninsured worker is hurt on your roof, the exposure can land on your homeowner policy.
Get everything in writing, including the unknowns
Anything agreed verbally will be remembered differently on day two. In particular, pin down the decking rate, the start date and the clean-up before you sign.
Be careful with the deposit
Ten to thirty per cent is normal, often to order material. Full payment before work starts is not, and in several states it is not even legal. Hold the final payment until you have walked the job.
Check the licence yourself
A licence number on a business card is not a licence. Look it up, confirm the name on the licence matches the name on the contract, and check the status is active today.
Prefer somebody you could drive to
Ask where their yard is. Companies that follow storms across state lines do competent work and then vanish, which is fine right up until something needs putting right.
In short
Do the boring checks. They are the entire difference between a roof that is somebody else's problem for ten years and one that is yours.
Related questions
What time of year is best to re-roof in Diamond Bar?
Here, the long dry run from May to October is the easy window. November through March is when the phone rings hardest, which means less flexibility on dates and less room on price.
Do you cover the whole Los Angeles County area?
Yes. The contractors we match on cover Diamond Bar and the surrounding towns, so if you are just outside the city limits it still works.
Do you handle commercial buildings?
Yes. Commercial requests go to contractors who do low-slope and flat systems rather than to residential crews. Say so on the property question and it routes correctly.
Ready for a real number?
No cost. We email you once when a provider near you can take it on.
