Thomas Clemmer
I've had the pleasure of working with Guardian Roofing on multiple new and reroofing jobs and every single one has been an excellent experience. First class service from a first class team. Punctual and always delivers on what is agreed upon. Guardian Roofing is always the first on my call list for any roofing job.

I have worked with John Dondero on helping our customers with their roofing needs. He is knowledgeable, professional and always on time. They are an awesome,
local, family run company. Guardian Roofing will always be our choice in a Roofing company.
Nate Auerbach
We've had a mystery leak at our business for years that no one had been able to solve after dozens of attempts from several other roofers. John came out and was quickly able to identify the problem and correct it. We've since made it through several storms leak free. I can't recommend John and his team highly enough. The efficiency and quality of work is top notch.
Jennifer Moezzi
Guardian Roofing was a referral from my dad. They did a great job for him. We used them for many services and found them to be easy to work with, respectful and thorough. Our roof, skylight and gutters look wonderful and we are very pleased with their workmanship. They gave us a very reasonable price. We are greatful for their integrity and service.

When our roof started leaking, we called Guardian. They responded immediately, and quoted a fair price. The installation went smoothly and looks great. Guardian staff are courteous and professional. They care about their customers.
