Complete Guide to Shed Roofs: Design, Installation, and Costs
What Is a Shed Roof and Why Choose It?
A shed roof is one of the simplest and most practical roof designs, featuring a single sloping surface. Unlike pitched roofs with multiple slopes, a shed roof is straightforward, affordable, and easy to build.
Historically, shed roofs were primarily used for outbuildings, barns, and lean-tos. Today, they’re also popular in modern home architecture, thanks to their clean, minimalist look. Visit types of roofs, (dont forget to read our blog about how to get insurance to pay for roof replacement).
Benefits of shed roofs include:
Cost-effectiveness – fewer materials and less labor.
Simplicity – easy installation and quick construction.
Versatility – works for sheds, garages, cabins, and modern homes.
Good Drainage – water flows off naturally due to the single slope.
In short, when people ask “What is a shed roof?”, the answer is: a functional, affordable, and stylish design that’s ideal for both small structures and contemporary houses.
Types of Shed Roofs
There are several shed roof styles that vary by slope, application, and design preference.
Single Slope Shed Roof
The single slope shed roof (also known as a skillion roof) is the most common type. It has just one continuous slope, often angled steeply to allow efficient water runoff.
Best for: Sheds, porches, small cabins, and modern minimalist homes.
Lean-To Shed Roof
A lean-to shed roof is essentially a single slope that leans against an existing wall or building. This style is often used for extensions, storage sheds, or garden shelters.
Advantages:
Saves space by attaching to another structure.
Requires fewer materials.
Quick to build for DIY projects.
Materials for Shed Roofs
Choosing the right shed roof materials impacts cost, durability, and appearance.
Metal Shed Roofs
A metal shed roof is durable, lightweight, and long-lasting.
Pros:
Lifespan of 40+ years
Fire-resistant
Excellent for snow and rain runoff
Cons:
Louder during rainstorms
Can dent from hail or falling branches
Asphalt Shingle Shed Roofs
A shingle shed roof is one of the most affordable options, especially for small structures. Asphalt shingles are easy to install and widely available.
Pros:
Cost-effective
Variety of colors and styles
Average lifespan: 15–25 years
Cons:
Shorter lifespan than metal or tile
Requires more maintenance
Other options include wood shakes, slate, and polycarbonate panels, though these are less common for basic shed roofs due to cost.
How to Install a Shed Roof
Building a shed roof is manageable for DIYers with basic carpentry skills.
Preparing the Shed Frame
Before installing the roof, the shed frame preparation must be solid and level. Ensure walls are square and properly anchored.
Roof Sheathing and Waterproofing
Apply roof sheathing (plywood or OSB boards).
Install an underlayment or roofing felt.
Use waterproofing membranes for added protection.
Proper shed roof waterproofing is critical to prevent leaks.
Applying Roofing Material
For metal shed roof installation, secure panels with screws and flashing.
For shingle shed roof installation, start from the bottom edge and overlap rows upward.
Whether using shingles or metal, always follow manufacturer instructions and local building codes.
Shed Roof Cost and Budgeting
The shed roof cost depends on materials, size, and labor.
Average Costs:
Asphalt Shingles: $2–$4 per sq. ft.
Metal Roofing: $5–$12 per sq. ft.
Labor (if hired): $40–$80 per hour
Cost to build a shed roof:
Small shed (100 sq. ft.): $300–$700
Medium shed (200 sq. ft.): $600–$1,500
Large shed (400 sq. ft.): $1,200–$3,000+
DIYers can save significantly on labor costs.
Maintenance and Longevity of Shed Roofs
The shed roof lifespan depends largely on material choice:
Asphalt shingles: 15–25 years
Metal roofing: 40–50 years
Wood shakes: 20–30 years
Maintenance tips:
Clean debris from roof surface and gutters regularly.
Inspect after storms for loose shingles or bent panels.
Reseal flashing and joints every few years.
Regular shed roof maintenance prevents leaks and extends lifespan.
Common Problems with Shed Roofs and How to Fix Them
Despite their simplicity, shed roof problems can occur.
Leaks: Often from poor flashing or damaged shingles. Fix with sealant or patching.
Sagging: Caused by undersized rafters or heavy snow loads. Reinforce with braces or replace rafters.
Ponding Water: Usually from too shallow a slope. Correct by re-sloping or improving drainage.
Prompt shed roof leak repair prevents long-term damage.
