Why are flat roofs common on commercial buildings?
Summary
Commercial buildings are typically large in size. It makes them easier to construct to give the most size for the dollar and last longer. They also can hold all the equipment that is need for a larger building.
______________________________________________________________________________________________________________________________________
With larger buildings, comes with more equipment needed for them. Saving space by putting in on the roof is the best way to go about that. Having a flat roof on commercial buildings is common due to that reason. Flat roof materials last a long time if installed correctly, that’s why choosing the right contractor for the work is equally important as the material and cost itself.
How do I know if I need my flat roof replaced?
Summary
A flat roof may need to be replaced if it has reached the end of its service life, has extensive damage, or repeated repairs are no longer effective. A previous recover does not automatically mean the roof needs a full replacement. In many cases, the existing recover can be removed and replaced with a new roofing system, as long as the underlying roof assembly is dry and in good condition.
______________________________________________________________________________________________________________________________________
Some reasons to replace a roof: if it is in need of major repair work and costs begin to reach higher than the typical budget, insulation is showing buckling, has soft spots, or is wet, or if you are looking for a long term solution with new technologies that have come out. Having lower maintenance costs, saving on energy, and having protection for a long time are all benefits of having your commercial roof replaced. It is always good to find a trusted roofing professional to give an inspection of the condition of your roof for the best options for your roof!
What is BUR roofing?
Summary
Built-up-roof. It is a tar and gravel style roof. Installers will lay 90 lb. felts (3 or 4 plys) and tar those together and then a layer of tar with pea gravel on top.
______________________________________________________________________________________________________________________________________
Built-Up Roofing (BUR), often referred to as a tar and gravel roof, consists of multiple layers of roofing felt and asphalt. Depending on the system, the roofing felts may be mechanically fastened to the roof deck. A layer of gravel is then applied to help protect the membrane from UV exposure, reduce weathering, and provide ballast for the roofing system. While BUR has been used on commercial flat roofs for many years, it has become less common due to the increased popularity of newer roofing systems.

Can a roof leak happen even if the shingles look fine?
Summary
Yes. While damaged shingles are a common cause of roof leaks, they are far from the only one. Leaks can also result from issues with ventilation, flashing, vents, installation details, or other components of the roofing system, even when the shingles appear to be in good condition.
______________________________________________________________________________________________________________________________________A roof is made up of many components that work together to keep water out. If any one of those components fails or is installed incorrectly, a leak can develop even if the shingles themselves still look perfectly fine.
Some common causes include:
- Ice dams and attic moisture: Improper ventilation or insulation can allow ice dams to form along the roof's edge. Condensation or ice can also build up inside the attic. When temperatures warm, that ice melts and can work its way through the insulation, causing water damage inside the home.
- Improperly installed sidewall flashing: Flashing is designed to direct water away from areas where the roof meets a wall. If it isn't installed correctly, water can find its way behind it and into the home.
- Roof vents: Vents can leak if they were not installed properly or if wind-driven rain or snow is able to enter through the vent openings.
- Incorrect shingle installation: If the shingle seams are not staggered properly during installation, water can follow the seams and create a leak.
- Insufficient shingle overhang: If the shingles do not extend far enough over the drip edge or gutter apron, water may not drain correctly and can work its way underneath the roofing system.
- Improper window or siding flashing: If windows are not flashed correctly or the siding was installed improperly, water can get behind the siding and leak behind the roof flashing, making it appear that the roof itself is leaking.
- Exposed fasteners: Fasteners that are left exposed or are not sealed properly can become entry points for water over time.
Because roof leaks aren't always caused by obvious shingle damage, it's important to look at the entire roofing system when identifying the source of a leak. A thorough inspection can determine where the water is entering and what repairs are needed.

What size hail causes roof damage?
Summary
The size of hail is only one factor in determining whether it will damage your roof. Wind speed, hail density, the volume of hail, and even the temperature at the time of the storm all play a role. In many cases, hail around 1.5 inches in diameter or larger is more likely to cause roof damage, but smaller hail can also cause damage under certain conditions.
______________________________________________________________________________________________________________________________________
While larger hail generally has a greater potential to damage a roof, there isn't a single size that guarantees damage. Factors such as strong winds, the hardness of the hail, the age and condition of your roofing materials, and how long the storm lasts can all influence the severity of the impact. Because damage isn't always visible from the ground, it's a good idea to have your roof inspected after a significant hailstorm if you have any concerns.
What does hail look like on a roof?
Summary
On asphalt shingles, hail damage often appears as areas where the protective granules have been knocked away or as bruising that can expose or fracture the fiberglass mat beneath the surface. On Duro-Last roofing systems, hail damage may not be immediately visible, as spiral fractures can take time to develop before leading to leaks.
______________________________________________________________________________________________________________________________________
Hail damage isn't always easy to identify from the ground, and in some cases, it may not become noticeable until weeks or even months after a storm. On asphalt shingles, look for dark spots where granules are missing, soft bruised areas, or exposed fiberglass matting. On Duro-Last commercial roofing systems, hail can create spiral fractures that may not appear right away but can eventually allow water to penetrate the membrane. Because some forms of hail damage are subtle, a professional roof inspection is often the best way to determine whether your roof has been affected.
Should skylights be replaced every time the roof is replaced?
Summary
Yes, skylights are meant to last the life span of a roof, around 30 years.
______________________________________________________________________________________________________________________________________
If skylights are not replaced every time you get your roof replaced, it will increase the cost of the skylight labor and materials. While you could get a couple more years of life out of them, they could start leaking on your new roof causing more problems. It is better to simply replace them while you are getting your roof replaced to avoid any issues down the road.
When is the best time to have a chimney tuck pointing completed?
Summary
We recommend having chimney tuckpointing completed before your roof is completed.

What if gutters straps are improperly fastened to the roof deck?
Summary
Gutter straps should never be fastened to the roof deck.
______________________________________________________________________________________________________________________________________
Doing so can cause shingles to lift, increasing the risks of leaks, especially during the winter. Gutters should be fastened to the facia instead. If they are attached through the roof deck, they will need to be removed and reinstalled with every roof replacement. Be sure to talk to a trusted contractor when installing gutters so there won't be any issues in the future.
When does shingling stop for the year?
Summary
We generally stop shingling in November due to the MN climate.
______________________________________________________________________________________________________________________________________
We stop installing shingles at the end of fall and pick up again in the spring. To maintain the manufacturer's warranty, shingles should typically be installed when temperatures are above 20°F. Since shingles also need sunlight and warmer temperatures to seal properly, 40°F or higher is ideal, which is why spring and fall are typically the best times for installation.
Does the shape of the shingle matter?
Summary
Yes, but primarily for aesthetics and performance. Different shingle styles can change the appearance of your home, and some, such as laminated (architectural) shingles, are built with multiple layers that can provide greater durability and improved impact resistance than traditional 3-tab shingles.
______________________________________________________________________________________________________________________________________
While many homeowners choose a shingle based on its appearance, the style of the shingle can also influence its overall performance. Architectural (laminated) shingles are made with multiple layers of material, making them thicker and generally more durable than traditional 3-tab shingles. Depending on the product you choose, they may also offer higher impact and wind resistance. Choosing the right shingle comes down to balancing your home's style, your budget, and the level of protection you want from your roof.

How do I know if I need my roof replaced?
Summary
The main factor is the shingle granules which protect the asphalt matting from the UV. Granules naturally shed with normal wear and tear. Once there is significant granule loss, it’s time to consider replacement. There are other factors like thermal cracking, wind/hail damage. The frequent freeze/thaw cycles in Minnesota can cause shingles to fail sooner than in other regions. Typically 20-25 years max is the life expectancy for standard asphalt shingles.
______________________________________________________________________________________________________________________________________
Knowing the age of your roof can help determine whether it may be time for a replacement, especially if your home has experienced multiple severe storms over the years.
