Khalil and Ali did an amazing job upgrading our roof. Khalil provided us with a very detailed estimate with separate cost estimates for different parts of our roof that needed attention. In the end, we decided to take all of Khalil's advice and replaced our shingles, added a layer of plywood to strengthen the roof, upgraded ventilation and changed our eavestroughs, soffits and fascia, including adding potlights. We are very confident that the roof was done right and will last a very long time, plus it updated the appearance of our 50+ year old house. Thanks Khalil and Ali!
