Shingling a gambrel roof, known for its dual-slope design, demands precision. With over 15 years of roofing expertise, I offer this guide to help you achieve a durable, well-shingled gambrel roof.
My extensive roofing experience and hands-on knowledge ensure that this guide is reliable and practical.
Understanding a Gambrel Roof
What is a Gambrel Roof?
A gambrel roof features two distinct slopes on each side. The steeper lower slope maximizes attic space, while the shallower upper slope enhances the roof’s aesthetic.
Key Characteristics
| Feature | Description |
|---|---|
| Lower Slope | A steeper angle, provides more headroom |
| Upper Slope | Shallower angle, enhancing aesthetics |
| Increased Attic Space | Allows for more usable space under the roof |
How to Shingle a Gambrel Roof
Shingling a Gambrel roof is actually similar to shingling a common roof. There are no specific instructions to follow. Below are the detailed instructions:
- Preparation: Ensure the roof deck is clean and in good condition. Install a drip edge along the roof’s edges to prevent water damage.
- Underlayment Installation: Roll out roofing felt over the roof deck, starting at the bottom edge and working upwards. Secure the felt with roofing nails, overlapping each row by about 4 inches.
- Installing Starter Shingles: Begin at the bottom edge of the roof and install starter shingles along the eaves. Cut the shingles to fit and secure them with nails.
- Shingling the Lower Slope: Lay the first row of shingles directly above the starter shingles, ensuring a proper overlap. Use a chalk line to maintain straight rows. Nail each shingle according to the manufacturer’s instructions.
- Transition to Upper Slope: Use flashing at the transition point between the lower and upper slopes to ensure a watertight seal. Start shingling the upper slope, overlapping the lower shingles.
- Completing the Upper Slope: Continue shingling up to the ridge, maintaining alignment with a chalk line. Install ridge shingles along the roof’s peak to complete the installation.
- Final Inspection and Sealing: Conduct a thorough inspection of the entire roof. Ensure all shingles are properly secured, and apply roofing sealant to any exposed nails or potential leak points for added protection.
In one of my projects, we shingled a gambrel roof on a restored barn. Ensuring a smooth transition between the slopes was crucial. We achieved a durable and visually appealing roof using high-quality flashing and aligning each row of shingles precisely.
A case study of a colonial home with a gambrel roof showed that using high-quality materials and following precise installation steps significantly extended the roof’s lifespan.
“Ensuring a seamless transition between the slopes and using durable flashing are critical for the longevity of a gambrel roof.”
Common Challenges and Solutions
| Challenge | Solution |
|---|---|
| Transition Between Slopes | Use flashing to ensure a watertight seal |
| Maintaining Alignment | Use a chalk line and measure regularly to keep shingles straight |
| Working on Steep Slopes | Use safety harnesses and ladders for stability and safety |
How to Shingle a Gambrel Roof Shed
As mentioned under the sub-headline, shingling a Gambrel roof shed is done like that. Shingle can be done on a sunny day to ease your job. The heat can help the tarred shingles to be more flexible.

Shingle Gambrel Roof Transition
Shingling a Gambrel roof transition will require you to shingle the lower pitch first. Then, if you’ve reached the upper edge:
- You should ordinarily apply shingles until reaching the top row, which connects to the next shallow slope. To do that, do every step of the details above. Suppose you got the upper part of the shingles too long and extended it above the edge—there is no need to change that.
- Continue by placing the shingles in the shallow slope of your Gambrel roof. Make it extend the edge so the shingles overlap with the lower side shingles. Combine them all and secure them with a nail-like usual.
All right, those are the steps for shingling a Gambrel roof. You might wonder if you can use architectural shingles on a Gambrel roof. You can use any shingles while shingling your roof.
However, it might be more difficult to do as architectural shingles are much thicker and heavier by at least 50%. Also, bear in mind the architectural shingles will cost more. However, despite the drawbacks, the finished look will be better.
It also offers many upsides, especially its longevity. Therefore, choose one which suits your style and, most importantly, your budget.
Conclusion
Shingling a gambrel roof requires careful planning and precise execution. You can achieve a durable and aesthetically pleasing roof by following the steps outlined in this guide and leveraging my extensive experience. Proper preparation, quality materials, and meticulous installation are key to a successful project.
