Their english is not the greatest, however, they make up for it and more with their honesty, hard work, fairness, price and quality of work! I was skeptical at first, but Mr. Lin was adamant he could do the whole job effectively and at a great price. I had raccoons trying to get into the attic. The shingles were a bit soft, however, the roof doesn't need to be changed for at least another 5 years. Nevertheless, the raccoons found a couple of weak spots and started ripping out the shingles and chewing away at the plywood underneath trying to get into the attic. Lin put aluminum flashing along the entire length of the house along with new shingles and checked the rest of the roof and addressed weak spots as needed (nails, new shingles, tar). Below are pictures of the raccoon damage. The last picture is the finished result. I highly recommend them for their honesty, integrity, quality of work and great price. I definitely recommend!
