Purchasing windows for your home is a large investment, and we make it our mission to remove any hassle from this undertaking. Our windows are designed to deliver durability and energy efficiency, providing the best value for your home.

Common Window Types We Service

RoofPro offers high-quality, energy-efficient windows that you can depend on. Whether it’s classic designs like double-hung windows or more elaborate bow or picture windows, our experts have extensive experience with all models of windows, and we are more than happy to serve you. Here are the common models we install:

Double Hung

A double-hung window is a type of window that has two operable sashes that slide up and down. Both sashes can be locked in place for safety or removed, and both can provide ventilation. 


A casement window is a window that is attached to its frame by the hinge at its side. They can be installed as a single-window or in pairs within a common frame. A casement stay holds them open, allowing for easy cleaning.


A picture window is a large window that doesn’t open up. This window design aims to provide a clear and unobstructed view of the outside, framing it like a picture. These windows are designed to provide maximum visibility and light for both inside and outside the home. Since picture windows do not open, they are often paired with ventilating windows to prevent moisture build-up.

A slider or gliding window has a sash or panel that slides either left or right in a single frame. Slider windows come in many different designs, with up to three different panels, but the defining aspect of a slider is that you can always push one or more panels to the side to open the window fully. Like picture windows, these windows are optimized to provide unobstructed light.


A bay window is a three-sectioned window that projects outward. The middle window is a picture window with two smaller windows flanking either side at a 45-90 degree angle. A small roof section is usually built across the top of the bay.


A bow window projects or bows outwards in a curved shape. They consist of multiple sections of equally sized window shapes and join together to form the arched “bow” shape that protrudes from the flat exterior of the home.


Roofpro offers a wide variety of window designs to fit your unique style. Our windows are based on your specifications and offer customization on pane glass, custom colors, shapes, and grid patterns.

When to consider replacing your home windows

Outdated or damaged windows can lead to high energy bills and structural damage, and most importantly, it doesn’t make your home feel safe. Here are some tell-tale signs that you need to replace your windows.

Cracked or Damaged

Cracked or damaged frames will allow the outside elements to penetrate your house easily. If left untreated, the frame damage can cause structural damage to your home, so if you see any visible damage, seek a professional immediately.  


Heavy condensation build-up signifies that the frames are cracked or decaying. If you see condensation build-up between the panes, it’s time to call a professional. 

High Electricity Bills

Older single-pane windows lack proper insulation, which means your AC and heating systems will need to output significantly more power. To prevent this, update your windows and consider double or triple-pane windows. Updated designs provide better aesthetics and help prevent air transfer and heat loss, which will save immensely on energy bills.

Can’t Close Them

A common problem as windows get older is the presence of dirt and dust build-up, which affects the sliding track. In addition, a functioning lock provides an added seal for trapping in air, so if you can’t properly close your window, you should consider repairs or calling a professional. 

Updated Look & Feel

New windows enhance the natural beauty of your home both internally and externally. You can drastically enhance whatever color theme you desire with different finishes such as wood, fiberglass, and vinyl. Additionally, updated windows can increase the overall value of your home by making it more attractive.

Yes, new windows are worth it as they provide a strong return on your investment and can drastically increase the value of your home, but new windows are not for every home. A replacement window has an ROI of up to 85 percent, but it’s also important to balance the cost of materials. When replacing your windows, you can choose cheaper frame material, which saves you money initially but will cost you more in energy bills as you have less durable material to provide insulation.

Window replacements take around 40-60 minutes each so that windows can be replaced within a standard 8-hour workday. Window replacements usually take roughly 4-7 weeks after ordering the windows.
