Our History

Delbert H. Mayou founded Mayou Roofing in 1940 and since then we have been serving Ottawa and the Illinois Valley area for over 60 years. There have been a lot of companies that have come and gone in that time. Mayou Roofing has established and maintained a reputation of expertise and excellence in commercial, industrial and residential roofing.

We are not concrete contractors or general contractors who happen to do roofing, we are professional roofing contractors and we have the experience and equipment to do your roofing job right.


Mayou Roofing has been successful because we install quality roofs at a fair price. Some companies only offer one type of roofing material, even though it may not be the right solution for your roofing needs.

Mayou Roofing has been able to stay in business so long by installing quality roofing. That means specifying the right material for each job; there's no cutting corners or offering the cheapest materials just to sell the job.
