A lean-to roof is a single sloped roof that attaches to an existing building. Homeowners most often use lean-to roofs for home and outbuilding additions.
The most significant advantage of a lean-to roof is the easy construction. Since these roofs only have one slope, they don’t require a lot of material or labor costs.
If you’re considering adding to your house, garage, or outbuilding, here’s what you should know about lean-to roofs.
What is a Lean-To Roof Design?
A lean-to is a shed roof featuring one sloping side that butts up against an existing structure. Contractors use lean-tos to add on to houses or outbuildings. Lean-tos can be enclosed on all four sides or left open, depending on the use.
Since lean-tos have a steep pitch, they prevent water or snow from piling on the roof but require gutters for adequate drainage.
What is a Double Lean-To Roof?
A double lean-to roof occurs when two lean-to roofs butt up against one another at their lowest peak, forming a “V.” Double lean-to roofs are not as common as single lean-to roofs.
