Anyone can call themselves a contractor, but not everyone is licensed. We are registered with the state of Montana’s Construction Industries Board, which means we meet and work to maintain industry-wide requirements for safety, liability, education and more. We are a Montana owned and operated company, and we have been since our founding in 1997. As an established, local company, we carry insurance, liability and labor warranties for our customers’ protection. In short, we’ll be here whenever you need us. Out-of-town companies and fly-by-nights, on the other hand, often can’t be counted on to honor their warranties – or even be around when the time comes.

Experienced contractors should be able to determine accurate budget numbers at the frontend of any project. That’s why we offer free estimates on every job. We wouldn’t make a decision without first having the information we need to set clear expectations, and we don’t want our customers to, either.

If you have loose, broken, bent or split shingles, make sure you replace them in a timely fashion. If the shingles on your roof are damaged, they can’t fully protect your home, so they longer they stay in disrepair, the more susceptible your roof is to harm. Be careful when climbing up on your roof, though. If you don’t feel confident and comfortable replacing the shingles yourself, call Donahue!

The type of valley used for a roof depends on the roofing product being installed. Open valleys, which are required for some products, are used for thicker designer shingles to eliminate a hump look when a closed valley install is performed. Open valleys are also used to direct water away from the roof with a center rib in the middle of the valley. Closed valleys overlap two slopes to create the finished valley

A ventilation system might seem like an odd thing to have on a roof, but it’s essential for the proper function and optimum life of a roofing system. Roof vents allow hot air and moisture to escape from attics and other areas of a home, preventing mold, mildew and other factors from damaging a roof and potentially causing health concerns. There are many different roof vents – each with its own strengths and weaknesses – the most common types being box vents, ridge vents, wind turbines, power vents, off-ridge vents, cupolas and soffits. Using a ventilation calculator (smartphone apps available) can help find the appropriate amount of ventilation needed for your house. We can also determine which vent or combination of vents is best for your home. We love solar-powered ventilation. It has the most power, requires fewer holes in your roof and comes with tax-incentive rebates.

Cleaning your gutters at least twice a year can prevent damage to your roof. If leaves and debris clog your gutter, they can cause water to overflow, potentially damaging your roof – and eventually the foundation of your home.
