Hexagon Construction our company is based on the belief that our customers' needs are of the utmost importance. Our team is committed to meeting those needs. We welcome the opportunity to earn your trust and deliver you the best service. No job is too big or too small for our experienced team. Call today for a quote.

"This was my second project with HEXAGON CONSTRUCTION and by far the largest and most complex. (Replacing an old, clay tile roof on a three story house is no job for a rookie.) HEXAGON’s owner, Eli Vatkin, is what everyone should be looking for in a contractor. He’s knowledgeable, reasonably priced, trustworthy, responds promptly to any concerns that you have during the project, keeps you apprised of its progress, finishes on time, and generally aims to please. His contracts were straightforward and “by the book.” On top of that, he’s a genuinely nice guy. Rarely will you find all these qualities in a contractor—and I’ve been around long enough to know. "

"I don’t normally write reviews, but I had such a great experience with Roofing Angels that I had to share. Chuck was amazing—from the first meeting, he made sure I understood everything about the process and helped me choose the right materials for my home. No pushy sales tactics, just honest advice. His crew was super professional and hardworking. They showed up early, worked long hours, and always made sure to clean up at the end of the day. I was expecting a lot of noise and disruption, but honestly, it wasn’t bad at all. Now that the job is done, I can’t stop admiring my new roof! It looks perfect, and I feel a lot better knowing I won’t have to worry about leaks anymore. If you’re looking for a stress-free roofing experience with people who actually care, I can’t recommend Roofing Angels enough!"

"If I could give a 10 out of 5 stars I would. Argo from Sandoval roofing came out and gave me a quote which was very reasonable. After getting a few more quotes, we decided to go with Sandoval roofing to completely redo our roof and patio (new sheathing, paper, and tiles). We decided to go with them because they were quick to respond through call and text (even late at night), gave a good price, are licensed and bonded through CSLB, and have roofers with 25+ years experience (their roofer Francisco was awesome) They were able to start within a week of giving the quote, and finished the whole job in 4 days. The two bosses were on site to overview the job which I appreciated as well. Overall I could not be happier with this company. With all the bad contractors there are now a days it’s hard to find someone who does quality work at a good price, but Sandoval roofing did so. Sorry for the ramble, but they finished my roof today and I’m very pleased with it so I thought I’d share my whole experience."

FAQs for asphalt shingle roofing installation and replacement projects in Diamond Bar, CA

Roofing professionals can usually install a medium-sized asphalt shingle roof in two to three days. Installation time increases if your roof is particularly steep or difficult to access or has features like chimneys or skylights that roofers must work around.

Three-tab asphalt shingles usually have the lowest upfront cost of any roofing shingle material. They’re sturdy and typically last 15 to 20 years. However, they may have a shorter lifespan in especially hot or cold climates. Talk to a local roofing professional about the best materials for your climate. In some cases, materials with a higher upfront cost may save you more on repairs or replacements in the long run.

Start by multiplying the length by the width of your roof to calculate the square footage. Most shingle replacement costs $4 to $12 per square foot for materials and labor, depending on factors like the material and the slope of your roof. Once you know the size of your roof, you can calculate a rough estimate of total costs or contact a local roofing professional to provide you with a custom quote.

Asphalt shingles are generally considered to be a low-maintenance item. However, cleaning your asphalt roofing can help prolong the lifespan and keep it looking fresh. If you’re comfortable with DIY and have the proper equipment, you may be able to clean your asphalt shingles yourself. However, if you have an especially high or steep roof, it’s usually safer to hire a professional roof cleaner.
