Frequently Asked Questions


Do I need to be home when you come to do the estimate?
No, our estimators will come to your home and knock to let you know we are there. If you are not home or do not answer, they go about their business and leave you a card near your front door to let you know we were there.
If you do want to meet with one of our estimators, we would be happy to schedule an appointment. Just make sure to let us know when you call or make note of it in the comments section of our Request an Estimate page.


How do I know if my roof needs torn off?
The Minnesota Building Code requires that any residential property property that has 2 or more existing layers of shingles (or other roofing material such as rolled roofing) must be torn off. However, most roofs, even one layer roofs, should be torn off. There are a plethora of problems that could be occurring underneath your existing roof, such as rotting wood and undetected leaks. The only was to address these problems is to expose them.


Should my Drip-edge, Soil Stack Flashings and Chimney Flashings be replaced?
Yes, all roofing related items should be replaced at the same time your shingles are replaced. All of these materials are as old as the roof itself and are prone to similar wear-and-tear over the years just like your shingles.
The drip edge goes around the entire perimeter of the house to ensure that no wood is exposed and, as the name suggests, prevents dripping rainwater from damaging your sheeting wood. In its older age, it can rust, fracture and break entirely. This exposes your wood and leads to rotting.
Flashings is a procedure that must be done to anything that protrudes from your roof. Electric posts, soils stacks, chimneys and skylights are common things that protrude from roofs and there are two main ways the flash these items.
The first is for the soil stacks and electric posts. These types of items are of standard shape and size and have covers with rubber rings to slide over them before the singles are laid. Over the years the rubber ring can dry rot and would let water down toward the wood.
The second involves cutting various sizes of aluminum and a line into the chimney and bending the aluminum to fit into the line. This method yields very few problems, but many companies do not cut the line directly and fix the flashing into the chimney. They used caulking material to seal and prevent leaks, if the caulking material they use fails; your roof will leak.


Should my roof be ventilated?
Absolutely! Warm air rises and when that air can longer raise, the moisture it possesses condensates. The condensation will occur in your attic space where your sheeting boards are (the wood the shingle are nailed into.) The sheeting boards and insulation will absorb the moisture and begin to rot from the inside out. This will eventually let water from the outside in as well. In addition, the water that the sheeting boards cannot absorb will drip down onto your ceilings and cause water spots. You will think your roof is leaking, but it is really the water already trapped inside your home trying to escape! Your manufacturer's warranty for the shingles also requires that your roof is properly ventilated.


How much ventilation should my roof have?
There is no such thing as "too much" ventilation on a residential roof. Since the warm air will rise to the highest point in your attic, we use Everflo Concealed Ridgevent. It is placed along the ridge, or peaks, of your roof. This eliminates the possibility of any air becoming trapped and condensing. Another key benefit is that ridgevent eliminates the square box vents that protrude from many older roofs. Asphalt Roofing Manufacturers Association Roofing manual states that 1 square foot of ventilation is required for every 150 square feet of attic space, but we tend to install much more than this to ensure the quailty of your roof. In some special cases additional ventilation may be needed, but if you are one of these cases we will be sure to thoroughly discuss the situation prior to the start of your job.
