"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."

Roofing FAQs, answered by experts

Yes, roofers can repair and replace roof trusses. In fact, because trusses are such an important part of your roof’s structure, it’s best to have a roofing contractor deal with a damaged truss. If you try to fix the problem without the right skills or knowledge, your roof could sustain further damage or even collapse.

An improperly installed skylight could potentially impact your roof's warranty. This happens because roofing penetration is necessary during skylight installation. Check your warranty information to verify. In most cases, having skylights professionally installed with proof that flashing is being done to specifications can be enough to preserve your roof's warranty.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

The most important thing to remember when laying shingles is to work from the bottom of the slope to the top. This leaves you with a top overlap that directs runoff from one row to the next until it reaches the eave for disposal. You should also make sure you follow the manufacturer's instructions and the local building code for nailing patterns and frequency so all of your hard work stays put through varying weather conditions.

Asphalt shingles, wooden shakes, and slate or clay roofing tiles are often replaceable without having to replace the entire roof. It's possible to replace just a few shingles or tiles without much trouble in the case of wind damage or other minor problems. DIYers can perform the task in some situations. However, professional repair is always the best bet when it comes to roofing.
