What clients say about MDG Builders
My Design Guide Inc recently installed a new roof and new windows for our house, and we couldn't have been happier! We originally contracted them to put in new windows, but when we suddenly found ourselves in need of a roof fast, we talked with David, he and his team sprinted into action to accommodate our situation so we could have it done within a week. Throughout the two installation jobs, David was responsive, attentive, and very thorough in explaining the process to us. He was also upfront and honest on his pricing, no surprises. We would definitely work with them again on our future home improvement needs.
From the beginning, we had a great experience with the team at My Design Guide Inc! We wanted to upgrade our patio but we weren't creative enough to know what to do. David was full of great suggestions to make the patio a true conversation piece while still honoring our budget and we couldn't be happier with the result! The quality of work and professionalism is the best I have seen in this business, and they really do take pride in their work. David communicated with us throughout the process and was meticulous in ensuring our yard was still taken care of during the construction period. We have received so many compliments on our new paver patio, fire pit with seating, and built-in outdoor counter. I highly recommend going with them. I would go with them again a hundred times over!
We had no idea where to start, we had a large project with so many moving parts can be very challenging for novices like us. From the very beginning, Emil was responsive, helpful, timely with any questions, night and day. Since this was a gut job we were even more nervous. We were astonished on just how easy the whole process was with no hiccups at all. Less than 3 weeks and we had a wonderful spa. His workers were responsible, timely, responsive and did an amazing job down to the little details. Even our friends were surprised we had such an easy time with the job. Book them for any job because you will not be disappointed.

Cost guides:
How much does a new roof cost in Southern California?
For about 2,000 sq ft of roof: composition shingle $12,000–$28,000, concrete tile $24,000–$45,000 and clay tile $30,000–$60,000.
Who installs the roof?
Roofing on MDG Builders projects is performed by C-39 licensed roofing subcontractors, scheduled and managed by our team.
How do I know if I need a new roof or just a repair?
Isolated leaks and flashing issues can often be repaired; widespread granule loss, cracked tiles, multiple layers or failed underlayment point to replacement.
How long does a roof replacement take?
Many homes are re-roofed in a few days once materials are on site; tile and structural repairs add time.
Do I need a permit to replace my roof?
Generally yes. The roofing contractor pulls the permit and the city inspects the work.
What is a tile lift and relay?
The existing tiles are removed, new underlayment is installed and the tiles are reset, replacing broken ones. It often costs well under a full tile replacement.
What roofing material lasts longest?
Clay and concrete tile generally outlast composition shingle but cost more and weigh more; the underlayment beneath tile still needs replacement over time.
