What is a lean-to roof?
A lean-to roof is a single slope with its upper edge adjoining a wall or building. A
lean-to roof is also known as a sloping roof and it is the most
commonly used roof in houses.
the lean-to roof used for?
This type of roof is
generally used for verandas, building simple extensions, carports and
lean to sheds. It is also used for storage building; if a building
needs more space, then the roof is built with an existing wall.
advantages of a lean-to roof
The simple design of the
lean to conservatory roof makes it far easier to install then a
luscious green roof for example. You may think that building a lean
to roof will be cost you a pretty penny, but it’s actually one of
the more affordable options. Another benefit of this roof is that
water and snow run off it easily during the chilly seasons, so there
is no need for added waterproofing. This roof is best for high
rainfall and snowfall areas.
needed for a lean-to roof
One of two materials can
be used: polycarbonate and glass. While the latter is more expensive,
it does have more advantages than the former:
Conservatory Roofs: This plastic roof material offers decent
insulation, and it’s lightweight and cost-effective. There are
however some downsides to using this material: it gets dirtier
quicker than glass has the limited soundproofing abilities. Hence,
this type of material is best used for rooms that won’t be used
regularly or for living/entertaining purposes. It is the ideal
option for a greenhouse for instance.
Conservatory Roofs: If you’re building a conservatory roof
that you will use regularly, such as a veranda, then a glass roof
might be the most suitable option. Glass units can be fitted with
most types of frames such as uPVC or wood, and it offers good
insulation and soundproofing that is superior to polycarbonate. This
makes it the perfect choice if you live in a bustling street and you
want to block out noise, or if you want to control the temperature
of the room.
involved in building a lean-to roof
Consult the local
building authorities: This is the first and most important step
in the process. You need to gather information such as permits you
will require, code prerequisites and property setbacks for storage
buildings. This will help you make informed decisions about building
your conservatory roof.
underground hazards: Before your start digging, contact a
utility location service. They will advise you on whether it’s
safe to dig in the area that you are planning your build your lean
to roof. Failure to do so could result in digging into an electric
line or pipe and you could be held financially liable for this.
Draw up a plan:
You need to consider the length and width of your roof, where it
will attach to the shed, and building it to withstand harsh weather.
Make sure you position the roof so that rain and snow is directed
away from the building’s parameter, especially if you live in an
area that experiences harsh rainfall and snowfall. Use a simple
gutter or downspout drainage piping to prevent pooling at the bottom
foundation: A solid foundation is key when it comes to
constructing a lean to conservatory. In this step, decide on the
materials you will use for the base. Considerations such as your
location and climate will determine the type of materials you pick.
amount of materials you require: After figuring out how much
material you need, work out the total cost of the items. This way
you won’t be shocked when you visit your nearest hardware store to
for building a lean-to roof
Now that the planning of
your structure is sorted, it’s time to get your hands dirty and
start the task of building. To make things as easy as possible, we’ve
created a step-by-step guide for constructing your roof.
Step 1: Mark the
area where you want to build the structure
Step 2: Measure 8
feet from the existing structure towards the outer direction. Now dig
a deep hole.
Step 3: Drive the
post in and fill the hole with concrete in order to set it in place.
Step 4: From this
existing post, measure 3 feet distance in the same line. Then dig a
hole and drive the second post in. Repeat this process for the third
and fourth post. Be sure to maintain the same distance as before
between the posts.
Step 5: Cut out a
notch on the top of your posts. This is where the supporting post
Step 6: Place the
supporting posts into the notches.
Step 7: Once this
structure is ready attach the metal purlins on the outward side of
the installed posts. Nails must be used for this so that it is
attached firmly in place.
Step 8: Fasten the
nailer on the side of your existing structure. Use high-quality
screws to drill in the nailer. You will be attaching the upper end of
your rafters on this.
Step 9: Attach two
planks on either ends of the nailer by nailing them firmly in, and
place them on top of the structure. Add a third plank in the center.
Step 10: Set the
roofing material by attaching wooden planks at regular intervals on
top of the roof as previously done.
Step 11: Measure
out your roofing material and place it over the base roof structure.
Screw it in with a drill and nails.
Step 12: Finally,
install the trim of your choice as a cover against the side
structure. Screw it in with a drill and nails.
costs of building a lean-to roof?
The total cost of
installing a lean-to roof is difficult to estimate. You need to
consider the type of materials you will use and add the costs of
contractor and builders’ fees if you plan on using them. As stated
above, glass is more costly than polycarbonate, but prices vary per
manufacturer. On average, if you’re using a steel base, it costs
anywhere between £1,000 and £1,500 for a small to medium lean-to
roof. The supply-only cost for a quality, small uPVC full-glass sided
lean-to with a polycarbonate roof is £2,000 to £2,500. As far as
contractor fees goes, each professional will charge a difference
price according to how established they are. It’s worthwhile to
request quotes from a few different places before deciding on one.
will it take to build a lean-to roof?
Again, this will differ
according to a few considerations. If you’re hiring a general contractor and builders, it should take roughly 3-4
weeks to complete. This is of course dependent on the availability of
the contractor and builders, and how much time they have to dedicate
to the project. If you are planning on building the roof yourself, it
may take longer depending on how much building experience you have,
