"Mo from Presidential Exteriors inspected our roof and did an excellent job. He was polite, professional, and friendly and answered all of our questions. He was very thorough, and showed us the problems with our roof both externally and internally. He explained how they would replace our roof and explained about all of their premium products, great insurance, great warranties, certified builders etc., that they provided. I know that building our new roof will be done well because they have such good materials, technique, and builders who will work on it."

Customers say: Quick response

"I called and left a message for a call back on Sunday and Jessie called me back on that Monday. I found him to be pleasant and very easy to work with. I advised Jessie what the problem was with mine and my tenants roof and I ask him what he thought it would take to repair both sides. He had quoted me a price, but after his assistant had looked at what was needed, he was upfront and advised that it would be more and gave me a bottom line price which I thought was reasonable and fair. Jessie's assistant came and completed the project in one day and I was pleased with the finished product. Thanks Jessie, I will refer and use your services again in the future."

"The whole experience was good. The warranty is exceptional The customer service was nice and the guys that actually installed the roof were hard workers. There are only two issues I had. One, the initial consultation lasted 7 hours. Between discussions about the roof to the actual roof inspection. Second. The Forman on the job barely spoke English. There was a gap that had to be overcame for understanding my questions I had. Towards the end, he offered to call someone to translate but that, I felt, was too little to late. But like I stated earlier, the group as a whole worked very hard and the roof looks great."

Roofing FAQs, answered by experts

A roof can collapse from a leak if the leak is left unattended long enough. A collapse will happen when the structural components of your roof become saturated with water over time. The roof deck or rafters can slowly weaken until they can no longer support the weight of your roof.

A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes—one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.

The best way to check if a roofing company is legit is by asking the roofer for their license number. They should have no issue providing you with this information if they’re legitimate. You can also look to see if they have an online presence, read reviews, and ask contractors you’ve worked with before if they know the roofing company.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

You can secure roof decorations like inflatables and other Christmas decor by tying a rope or attacking bungee cords to your roof clips. Depending on the pitch of your roof, you can use sandbags for extra support. Like with Christmas lights, avoid using staples or duct tape.
