PLEASE PLEASE PLEASE DO NOT HIRE!

I should have done my research on this company before the board decided to hire this roofing company.

On June 29th of this year we hired ACE Roofing to complete a large repair on a leak that we were having on one of the sections of the church (Central Seventh - Day Adventist Church) in San Francisco.
2 people showed up to complete the repair and they were extremely unknowledgeable of the task that had to be done. 1 of them even had a ankle monitor. Fast forwarding to a couple hours later, the whole church started smelling like smoke. We saw the worker worried and asked to see if he had a fire extinguisher and he did not...... Minutes later the fire started bursting from the top of the building. Fire fighters started arriving and it took over 100 fire fighters to get a hold of the fire.

From then to now ACE Roofing has been completely uncooperative on fixing the issue. They are really unprofessional! They have a good rating on google but going in more through into the bad reviews you see that many people have had issus with them.

Due to their unprofessionalism we have lost our 134 year old church, a place that helped the community and the homeless but overall we lost a staple of San Francisco history.

ACE roofing worked with us to re-roof our house a few years ago when we decided to put solar panels onto our roof. They took extra care and worked with me to make sure their roofing works together with the solar panel mounts.
Communication was a bit tricky at times, but nothing you wouldn't expect while getting a construction job done.

ACE Roofing Group fixed our entryway stairway leak years ago when no one else could - still perfect today. When home insurance co required roof upgrades, we called ACE immediately. Four technicians completed the work in 3½ days, answering all questions politely. The owner, John, personally inspected everything - his quality control is exceptional. The roof looks perfect and resilient. With a 10-year workmanship warranty, ACE's professionalism is unmatched. Highly recommended to all San Francisco and Bay Area neighbors!

Buyer Double Beware ! I paid full price to replace two small new tile roof and two flat roof. I almost got cheated with just one new tile roof. Jon attempted to just repair the second roof using my old tiles but was caught in the act! So prepare to climb up to the roof to check every step of the process. As shown in the pics. He put metal flashing Just half on my flat roof. It leaks in less than a year. Took many attempts for him to come…the reason, he said he was busy because of so many complaints!!! He eventually came and did a Sloppy job patching up my “supposed”brand new tile roof! I thought he was kind, honest and experienced when I first met him… but he is the exact opposite plus very unprofessional and unresponsive!

Buyer Beware! Long overdue review about incompetence and unprofessionalism dating back to January 2018.

I hired them to fix 1 leak and gained 4 more leaks. As a result of forgetting to seal several seams on the roof and then leaving it unprotected, it caused multiple leaks in home:

* Kitchen floor and counter completely flooded as a result of leaks from 2 different points and warped the counter-top and the wood floor.

* Guest bathroom floor flooded and water leaking from ceiling near light fixture.

* Door entry to downstairs leaked from two points and warped the wooden floor landing.

I wish I had done a better job researching him. I found the following out after the fact:

* Two complaints against Ace Roofing from the Contractor's Licensing Board that is posted on their website, one for insurance fraud.

* He has a "D" rating on Better Business Bureau .

You can find both documents online.

* I filed a claim with his insurance after the damage and was denied only to be told that any damage caused by his negligent roofing work will not be covered by his insurance, a clause that was included in his policy as an exclusion.

The insurance firm told me "We are not denying liability only coverage."

This a roofing company that has insurance that does not cover his roofing work. What is the point of insurance then?

John (the owner) sent his guys over to "patch" up the leaky areas twice. But the negligence of his workers had already caused the multiple leaks and created over $28,000 worth of damages in the home.

John admitted fault several times and stated that he'd preferred to not to go through insurance and offered me a "credit" of $500 to fix the floor, and $5,000 to do the sheet-rock work in order to settle.

Unfortunately, this did not come close to covering the damages of doing the repairs to my home.

As it stands today, my kitchen and guest bathroom still have open walls and ceilings. This has been since January 8th, 2018.

See my pics to view the damages to my home.

2 attempts were made to resolve this. On the first appt, he didn't show up, and the 2nd appt, he came in shouting profanities.

He then threatened to sue me for writing a bad review on Yelp, and then said that he will charge me $1000/week for every week that my Yelp review stays up.
