What Is A Roof Lift Loft Conversion And How Much Does It Cost
A roof lift loft conversion is the simple answer to those who want to convert their roof space into accommodation but dont currently have the headroom. The roof on the property is removed and replaced with a taller one to increase the head height in the roof void thereby allowing the loft space to be converted into usable accommodation.
It is hard to generalise on cost as so much depends on the size of the house and therefore the roof and also, what plans there are for the interior of the roof space once the new roof is in place. Change your original plan for a bedroom to a large kitchen or en-suite and you can easily add between £10,000 and £20,000 to your final bill. Fill out the form below to get a more accurate price from local loft conversion experts.
The best way to figure out the cost is to look at the pricing for a whole new roof including trusses, probably somewhere between £10,000 and £20,000, the final figure dependent on your choice of roof materials and size of the house. Add to this the average cost of a loft conversion which is between £10,000 and £40,000 again depending on the interior fittings and the type of loft conversion you have, for instance, including dormer windows will increase the cost as will a mansard loft conversion. This should give you a working average for how much a roof lift loft conversion will cost. However, a new taller roof with an interior converted to accommodation will hugely increase the value of your property.

Undoubtedly, its not worth taking these risks while raising your garage roof. Thats why before raising the garage roof, go to your local city authoritys planning office and file an application. After that, your local city authority will inspect your garage and give you permission.

Making A Vaulted Ceiling
In situations like the ones above, it can make sense to lift a roof in one piece and replace it without much structural modification especially with a trussed roof.
But while a trussed roof can be raised, it cant be modified to make a vaulted ceiling. You need to start with a stick roof to do that.
Exposing the underside of the sloped rafters is what creates the vaulted shape inside that youre looking for, and that means removing the ceiling joists first.
That breaks the structural triangle that holds the roof together, and requires additional framing work to restore structural integrity.
A common solution is adding collar ties, which are similar to ceiling joists but a little higher up. A vaulted ceiling with collar ties usually has a large flat area above the sloped sides.
If you want the ceiling vaulted all the way to the top it gets a little more complex, and youll need a structural ridge beam.
The ridge beam is at the very top pointy part of the roof.
What Happens To The Hvac System
When a roof or ceiling is raised, there is a strong chance your HVAC systemand electrical systemwill be impacted, especially if you have central heating and air conditioning. Working with complicated electrical and HVAC systems is the biggest argument for hiring a roofing contractor to work on this renovation project. A contractor will keep you from being injured and will also make sure your home is safe.

If your higher ceilings go into your attic space, depending on how high it goes, your attic air conditioning systems will have to be moved. This can be relatively simple if the attic is large or the ceilings are not raised dramatically. But regardless of how high the new ceilings are, ventilation will have to be re-routed through the new air ducts.

Labor Cost To Frame A Roof
Labor is typically charged by the hour at a rate of around $25 to $35 an hour for a total of about $2,500 to $3,000 of the $13,500 to $16,500 cost range. Labor is one of the smallest portions of the cost to build a truss roof. Material costs, including the factory assembly , the cost of the crane , and other incidental costs , make up the bulk of the project costs. Keep in mind that very tall buildings, large properties, and complex roofs cost more because they involve more material and labor. Costs also increase for roofs with a very steep pitch and those needing premium materials, such as steel braces.
When using a truss roof, the framing process is fairly simple. The trusses are ordered about three to four weeks before they are needed. They are factory-built and assembled with computer-aided technology to the exact specifications of your home and roof size. They will be delivered to the site on a flatbed truck. A crane is needed to lift the individual truss pieces into place, where they will be balanced and nailed into the frame of the home. The entire process can be done in less than a day once the trusses arrive, which is the biggest benefit of using this roofing system.

It usually takes about a month to raise the roof, sometimes longer. Would you be able to stay in your home while the work is ongoing, or would you need to stay with friends or family or at a hotel?
A roofing contractor can give you an estimate for the total cost of a roof-raising project and answer any additional questions you might have about the process.

Adding A Second Floor
As long as weve got that crane on site, lets take the roof up a little more enough to add an entire second floor.
Now were less concerned about the hinge, because were keeping the first floor walls the same height. Were going to add a new floor structure on top of the walls, then add new second floor walls on that.
Finally, well build new second floor walls and lower that roof back down.
Thats not too complicated but weve created additional structural issues to resolve first is the additional load of the new second floor on the existing first-floor walls can they handle it?
Second is the additional load on the foundation. Chances are it can easily take the extra weight, but youve got to have this professionally checked out, too.
Rewiring Electrical Connections And Redesigning The Plumbing
Do you have electrical connections and pipes that run up close to your roof? Even if you didnt before, youll need them now since youre turning that part of your home into a living space. The cost of rewiring electrical connections and rearranging your plumbing system is $4,000.
Hopefully, those alterations can be made without interfering much with the rest of your home. Thats not always the case, but it could be for your household.
Clear that matter up with the contractor before they start reconfiguring your wires and plumbing. Many of your homes fixtures may be out of commission while they work on those changes. You need to be ready if that turns out to be the case.
