Per facebook this company prides themselves on "great value, detailed and excellent work".

Well.. I'm here to let you know that you are none of those things.

For those looking for something done to their home, do yourself, family, and or friends, a favor and don't use this company.

Do not waste your time to get ripped off. He did not do what he said he would do and refuses to come back and fix his work. Thomas says he is scheduling to come back out then blocks your number and avoids the issues.

Again save yourself your money and heartache and DO NOT use this company.

For the record, this is not slander. Slander is "the action or crime of making a false statement damaging a person's reputation".

Unfortunately, nothing I have said above is false. If I were to rate this company based on our experience, it would clearly be a 0/10

Diamond State Gutters and Roofing delivered fantastic results. They offered fair quotes for a full roof replacement or repair and recommended the repair, which addressed our roof’s issues perfectly. John oversaw the work, which included fixing leaks, replacing broken tiles, and repainting siding. We even received detailed photos of the completed work. Outstanding job!

I called John out to my house to get an estimate on getting seamless gutters installed.

He was ver professional and polite, explained everything about the job in detail.

He gave a very competitive rate and seemed genuine so we set up a date to get the job done.

His team came out and got the job done in a timely manner, I would highly recommend John made the stressful process go smoothly and kept us updated the whole time.
