“I would like to thank you for a great job on the situation we had with our roof. Your customer service is excellent, your estimator was on time and courteous and the crew you sent out to do the work went above and beyond to make sure the roof was repaired. I asked for a follow-up inspection and your men were here the next day. Thank you once again for a pleasant transaction. Please feel free to use this letter as a testimonial for your company.”
