"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 with Integrity installed a new roof on my house, build new cement paver steps and install a new side door. In all instances, they did excellent work. Their pricing was fair and TJ, the owner was very responsive. Two of our neightbors expressed in new roof after seeing their work. I would recommend them to anyone."

Roofing questions, answered by experts

If your roof is nearing the 20-year mark in age, you probably should start worrying about the roof’s longevity. If you don’t know the age, it may be time to figure out who installed your roof, so you can estimate the age accurately. You then can make plans to pay for the upcoming roof replacement. You also can learn how to inspect a roof yourself to look for signs of damage that may indicate a need for a replacement.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.

Winter is the least expensive time of year to replace a roof due to decreased demand. However, it’s not an ideal time to replace your roof, as there are numerous factors that can inhibit the work, including shorter days, snow and ice, and cold temperatures.

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.

Shingle damage comes in many forms, and the damage usually depends on the wind speed and the shape of the roof before the winds. Typically, when shingles are damaged by wind, they become torn, creased, or detached from the roof. Some might go missing entirely. More extensive roof damage might occur if a tree branch or other debris has fallen onto the roof as a result of the windstorm.
