• Are all your installers insured?

Yes, all Mulligan workers are covered by State of Michigan worker's compensation and public liability protection.

• Do you use driveway safe dumpsters?

Yes. All dumpsters will be dumpster trucks on soft wheel pull dumpsters.

• Do you sub-contract?

No. All of our contractors work for us and only us. None of our work is sub-contracted out.

• How much can I expect to pay for a new roof?

The cost of a new roof depends entirely on how many square feet of roof you need to cover, and what type of shingles you are going to select. Mulligan features a wide range of standard and premium shingles to choose from. You can also contact a Mulligan associate and we will come to your home and give you a free quote.

• How many years should my roof last?

With proper venting, your roof should last as long as the warranty that is given by the manufacturer, but only with proper ventilation and installation. Learn more about proper ventilation.

• How do you know when it’s time to change your roof, and should I tear off the old?

1. It is important to keep all of the information from the last time that you had the roof replaced, in order to give you an accurate timeline.
2. When your shingles start to curl on the corners.
3. It would be time to tear off the old roof if you already have two layers on the roof. When you think that the second layer of roof is bad and you are leaning towards putting on a third layer of roof, Michigan Building Codes will not allow you to do that, two layers of roof is the most that you are allowed to have.

• How long will a roof job take?

It all depends on the size of your home, and how many layers of shingles are currently on your home. Some homes may have up to three layers of shingles on the roof. A ranch style house will normally take 1-2 days, a colonial style house will normally take 2-3 days, and a tudor style house will normally take 3-5 days.

• Is ridge venting better than canister venting?

The style of the house would determine if a ridge vent is the proper tool to help ventilate the house/attic. If the intake ventilation is done properly in the soffit area and is open to the attic, a ridge vent would work.

• Do you use staples or nails?

We use ONLY whole head nails. They are 1 ¼" to 1 ½" inch galvanized nails with a 3/8" head on the nail.

• How far up does your ice & water shield go?

Building codes for ice & water shield is 24” inside a heated wall area. That is minimum, so we take our ice & water shield six feet up from the eave and in all valley areas.

• Do you have the foam back siding?

Yes. We use a foam back siding product called Cedar Ridge which is manufactured by Crain.

• What colors of siding do you have?

We have a wide range of colors in vinyl siding ranging from white, blue, clay, earth tone colors and many more.

• How soon can you start and how long does it take?

We first need to have the agreement is signed and the materials are ordered, which can take anywhere from 10 days to 2 weeks. Weather can also play a small part in the installation of the siding, but mostly it depends on the size of the project. Ranch style homes usually take 1-4 days and a colonial style home usually takes 4-6 days.

• What colors will look good on my house?

When a representative comes out to your home, they are trained to help you select colors that would work best for the specific type of home that you have. They will help you to pick colors that will compliment the other colors on your home, such as your shingle colors and the colors of your windows. You can also launch our virtual home builder and see what siding colors will look good on your virtual home.

• Do you put insulation behind the siding?

If you are not having the foam back siding from Cedar Ridge by Crain, we always use a ¾" foam insulation behind all of our vinyl siding.

Are there different qualities of vinyl siding?

Yes. There are different gages in vinyl siding. The gage determines the thickness of the panel. The thicker the siding panel, the higher the quality. Visit our siding pages to find out all about Mulligan Premium Siding.

• How long is the labor warranty?

Mulligan has a Lifetime Siding Labor Warranty.

• Will the crews stay on the job until finished, or start and come back 1-3 days later?

Our siding crews receive one job at a time. So, when the work is started at your home, it is all about you and only you. We work the job from start to finish.

• Will new windows reduce outside noise?

Yes. The double pane thermal insulated glass and the welded mainframe and sash should reduce some of the outside noise, unless your window is open.

• How will the windows be installed?

Our windows are installed from the inside and the outside, about 50/50.

• Do you replace the sills?

We only replace the sills on a complete full pull with all new framing, casing and sills. On normal custom replacement, it is not standard.

• Fiberglass windows vs. vinyl windows?

Fiberglass windows will not have welded frames or sashes. They are constructed the old-school way, screwed and glued at the corners. Vinyl windows have a welded frame and sash.

• Who manufactures your windows?

The vinyl window lines that we carry are Republic and Alside. The wood window lines that we carry are Peachtree and Weathershield. Visit our windows pages to learn more about windows, bays & bows and patio doors.

• Do you have a showroom?

Yes.  Our showroom is located in Farmington, Michigan at 32700 W. Eight Mile Rd. Map this location.

• Are the installers your employees?

Yes. Our window installers work for Mulligan and only Mulligan all throughout the year.

• Do you haul away old windows?

Yes. We haul away all of the old windows and do a very thorough cleanup after the job is completed.

• How do you handle rotten wood?

Any rotten wood will be replaced that is part of the window installation only. We will only be checking for any rotten wood in the four sides of the window opening before installing the new product.

• Will the installers show me how the new windows work?

All of our window installers are instructed to show the homeowner how the window is operated before they leave. But, we must be careful in showing the homeowner how the window operates, since the window caulk needs to be dry to ensure a proper installation before being fully operated.

What kinds of fencing do you offer?

We carry a full line of vinyl and aluminum fencing.
