Roofing FAQs

How long should my roof last?

A typical asphalt shingle roof should last about 20 years. There are, however, factors that can increase or decrease the lifespan. Regular maintenance, good design, and good installation will lengthen the life of your roof. Trees, hail, critters, manufacturing defects, and poor installation can prematurely age your roof, often necessitating replacement.

Can I just shingle over the existing roof?

Not in the state of Minnesota.

What about warranties?

Iron River Construction offers upgraded 50 year manufacturer’s warranties. This includes both material AND labor, and is non prorated. You should never have to buy a roof again.

How much does a new roof cost?

It depends. How big? How steep? Are there any framing issues? What material are you going to have installed? What kind of warranty? All these questions can be answered at a free in home estimate from Iron River.

Why does my new roof look lumpy?

It may take a week or two for the shingles to “lay down” and adhere into one solid surface. Adhesion is achieved by the heat from the sun. It may take a little longer if your roof is installed in the winter.

Why is my roof stained and discolored?

Algae and lichen often grow on roofs, especially in shaded or damp areas. It can negatively affect the lifespan of your roof, but typically doesn’t do too much harm. Shingles manufactured today have algae resistant materials added, minimizing growth.

How do I prepare for roofing day?

Take down any valuables from shelves so they don’t fall from the vibration from hammering. Mow your lawn short to make it easier to find any loose nails. Clear your driveway. Clear the work area of any toys, hoses, debris. Leave a plate of cookies. We love cookies.

Why is there green or white stuff growing on my shingles?

Algae and lichen often grow on roofs, especially in shaded or damp areas. It can negatively affect the lifespan of your roof, but typically doesn’t do too much harm. Shingles manufactured today have algae resistant materials added, minimizing growth.

I just installed a new roof, why do I still have ice dams?

Ice dams are a symptom of improper ventilation and insulation-it has nothing to do with your shingles. Iron River Construction can have an inspector come out to troubleshoot the problem, and offer permanent solutions.

How do I know what color shingles I should choose for my house?

We have color samples, we can get actual shingles, we have done roofs in every color, and we can get you addresses so you can see what it looks like on an actual house, and we also can take a picture of your house, and superimpose all kinds of finishes. We have many tools to help you make a decision.

Why does my roof leak?

Most roofs leak where there is opportunity for water to get in. Skylights, valleys, vents all need to be sealed properly during installation. Sometimes it is roofing material defects. Sometimes it is storm or mechanical damage (trees, etc.)

Do you recommend skylights?

No.

What time of the year is a good time to install a roof in Minnesota?

Any day over 35 degrees, no rain, not too windy, and not too hot. Sometimes when a roof is installed on a really hot day you’ll get scuff marks from walking on it. When we install during the winter, sometimes it takes a couple of weeks for the shingles to lie down.

Why did you leave an extra bundle of shingles when the job was done?

This shingle bundle is for any minor repairs you might need in the future.

How long can I expect the crew to be working on my roof?

Average sized roofs should take less than two days to complete, although there might be an extra day of quality control and punch list.
