Why Us


A+ Better Business Bureau Ranking:  We subscribe to the highest business ethics, and handle your entire claim as if it were our own home.

Licensed, Insured, and Locally Owned: We live amongst our clients.  We contribute to the community.  And we will be here, unlike out of state fly by companies, to guarantee our work.

Industry Leading 15 Year Labor Warranty:  Most companies will only warrant their work for 5 years, whereas we do it right, and can warrant the workmanship three times as long!

Higher Quality Products:  We use the best, and that’s Owens Corning shingles, made here, and guaranteed with a Limited Lifetime Warranty.  We will not use some knock off cheaper shingle to save money.  Finally, we use synthetic underlayment under the roof shingles, rather than cheaper and less stable paper roll off. Even if this cost us money, we gladly do it. Doing it Right is More Important Than Making a Higher Profit.
