Recommended Customer Reviews

Very solid work for a great price. I'm so glad I chose these guys to fix my roof. I've lived in a few homes now and have had a lot of bad experiences with other companies. But from now on these are my go to people.

Great people and easy to get along with, they did as I said and they got the job done before the due date. HIGHLY recommend them!

From start to finish, All Tops is a professional and expert company. The team is punctual, courteous, and incredibly efficient. They will take time to explain the entire process and answer any question with patience and clarity. The quality of their work is outstanding and you can be confident in the durability and craftsmanship. It's rare to find a company that combines great service with such meticulous care.

Excellent company! They were very professional, quick and did an awesome job! John, the owner is upstanding and reliable. The crews were very hardworking and know their craft. The inspector was even impressed!

Great company! John the owner is a delightful English gentleman, very honest and very reliable. Old fashion principles he picked the wood himself that went on our roof! They did an awesome job! Highly recommend this company!!

do not have these jerks do your roofing! they will damage your items because they employee people that do not understand english and do not care about your items. they broke many of my items in my yard and when i found out that a glass cylinder to a lantern i can no longer use, i asked the guy who headed the project, juan and he told me that one of his guys broke it. i ased him when were they going to tell me? he said he would replace it. i have had to call 3 times now and john hung up on me before telling me it was not importatnt to replace it.
i am fileing a complaint with the better business bureau. john will not replace it because he denies that they broke it when juan told me they broke it.
run do not walk away from this company they leave do not clean all the crap up and john lied from the start when i asked him twise ""do i need to cover anything"" he saidd no. but when i witnessed his guy taking whatever he could find of mine to cover my fountain and they rifled thru my stuff to find things to cover other items of mine. i had tarps that i would have used if john did not lie.
they are not a good company to do business with!!!!

I've worked with John Poulter, Alltops owner, and his company employed crews on numerous solar installations. I truly appreciate the ease & fairness in which John provides. It's great to know I can trust my projects with this company and the homeowner's have been extremely happy with their level professionalism, superior quality workmanship and genuine care. I would highly recommend hiring this company for your roofing needs.

My husband and I chose Alltops for our house's reroofing project because owner John Poulter is very trustworthy and professional. He was referred to us by the real estate agent who sold us the house two years ago to help us evaluate the roof's condition. At that time he honestly assured us that, although in bad shape, we could wait another two or three years without leaking problems. So when we were ready to replace the wood shakes by concrete tiles (our choice of material), John promptly gave us a reasonable estimate that covered all costs with no down payment, and explained exactly how the project would be executed after we picked the tile we wanted and got HOA's approval, step by step, from the Structural Engineer's visit till the last City Inspection. The work was executed in five days, and John's team was friendly and did a great job with clean up each day. Thanks to Alltops, our house has one of the best looking roofs in the neighborhood now.

I refer Alltops to our solar Clients that need to re roof before installing solar panels. Alltops is one of the best in the business. Over 30 years of Experience. Great selection of roofing materials. Reliable Customer Service. Competitve pricing. Outstanding attention to details. The owner John Poulter oversees everything. There is nothing more expensive than a cheap roof. They offer a 20 year roofing warranty on GACOflex 50 year silicon sealant for flat roofs.

Looking for contractors is a real pain in the ass, especially when it involves something crucial like ""roof over your head."" It's not like trying a restaurant where you can simply switch and go somewhere else if you don't like the place. I actually took couple of days off from work just to research and get estimates from several roofing contractors. I called at least 10 contractors and got 7 quotes/estimates. Alltops wasn't the cheapest but I chose it for the following reasons:
1. Quote covered pretty much all unforeseeable costs, meaning no hidden costs. Few other contractors came in with lower quotes but they were going to charge additional fee for any bad wood they have to replace. Most of them were charging about $5/foot. With our house being so old, I didn't want to take any chances with
2. My very picky friend used them for his house in Cerritos and was very happy with the result. The company has replaced roofs on many other houses in my friend's neighborhood.
3. Owner John was not pushy and didn't talk or sound like a typical contractor or a salesperson. He didn't even ask for any money upfront. He said he doesn't ask for money upfront because consumers are scared of contractors taking deposit money and just disappearing. John also has a cool British accent.
4. Alltops provided the longest workmanship warranty of 15 years. Most other contractors were 5.
This is a complete list of work that was done:
-tore off 2 layers of previous shingles
-installed half inch sheathing
-laid 30lb. underlayment
-installed new Timberline shingles
-installed new metal flashings for pipes, valleys, and chimneys
-all new metal flashings were painted to match roof color
-dry rot and termite damaged eaves board were replaced, primed, and painted
Entire work was finished in four days and crew did a good job with clean up each day. Best part is, there was no additional cost. I paid exactly what was on the original quote.
There was one incident that happened on the first day of construction. One of the employees from an outside company that was doing the teardown, stepped on a bad wood and his leg fell through our bedroom ceiling, leaving a big hole. John was very apologetic about this and got his crew to fix it as soon as possible. It was a bit of an inconvenience but they did a good job patching it up and repainted our entire bedroom ceiling.
The reason I didn't give five stars is because the owner wasn't on site everyday. I didn't expect John to be on site the entire time but should've stopped by at least once everyday to check on progress and monitor his crew. I also need to wait and see if there are any problems down the road like leaks or loose shingles, and how responsive they are to warranty/repair work. But the overall work looks good and our house looks so much better with new shingles.
One last tip. When working with any contractor, make sure you get a lien release from the contractor and supplier after you pay them. You may even want to pay the supplier directly for materials so you don't have to worry about mechanics lien if the contractor doesn't pay the supplier.
