Zinc is one of the most popular metals used for roofing which can either be installed in shingles or sheets. It is both extremely durable and low maintenance, and works well on extensions and modern style homes due to its sleek modern finish. It is one of the more expensive options and has a relatively unsustainable production process, though is 100% recyclable once created. Metal roofs like zinc may require additional insulation against noise from rain and hail.
Zinc cost per m2: £30-£60
Thatched roofs are a staple of idyllic country living, made from straw, water reed, combed wheat, and other plants and grasses. The look is unique, typically associated with English country cottages. Though material costs are low, thatching requires niche expertise that will increase a professional’s fees. Maintenance is also high which will increase cost and affect long-term durability.

Other costs to consider
On top of the material costs, you need to consider the cost of installation, maintenance and repair throughout a roof's life. We always recommend hiring a professional whenever attending to your roof, so professional fees need to be carefully considered.

As well as different materials to choose from, roofs can take different shapes. The primary choice for any extension or new build project will be between a pitched or flat roof.
Pitched roofs are what many would consider traditional roofs, sloping downwards from a raised point. There are many different styles of pitched roof, such as:
- Gable: two sloped sides of equal size.
- Hip: four slopped sides, two large and two small.
- Pyramid hip: four sloped sides of equal size.
- Saltbox: two sloped sides, one short and steep, one long and slight.
- M shaped: exactly as it sounds, two peaks with a recessed middle.
A saltbox pitch gives this small flat a unique look and interior vertical space.
The slope of a pitched roof allows for natural drainage, a factor that needs more careful consideration when taking on a flat roof. The gradient of pitch roofs also needs thought however, as steep slopes are more technically challenging, requiring more expert knowledge and therefore a more expensive service.

Flat roofs are an increasingly popular roof choice, particularly for home extensions and annexes. As they are less complex than pitched roofs they can often be constructed cheaper and quicker. They also allow the potential for skylights, a hugely popular addition in home extensions that welcome heaps of natural light into a space.

Most areas of the home need general upkeep to prolong functioning use, however roofs are much better at keeping their problems hidden. Not only that, but the effects of unsolved roof issues could be very problematic and expensive to fix. So you should carry out these tasks to ensure the security of your roof.
Check your roof!
Unfortunately, roofs very rarely get the attention they deserve. It can be easy to go years without looking up on the shingles, especially when there is no need to. But the warning signs of roof damage will never be seen without looking, so it’s good to check atleast once a year.
Clear away moss
Moss is roof enemy number one. Not only does it hold water, damaging most building materials over time, but it can sprout underneath and in between shingles. By growing between the cracks, moss can actually lift, move and even completely dislodge shingles creating space for leaks. When removing moss we always recommend getting a professional on board. Roofs are places you can’t afford to make a DIY disaster.
It’s easy overtime for gutters to fill with debris and dirt. If water cannot properly drain it may back up and cause huge problems. This is especially important with drainage on flat roofs as backed up water could linger for long periods and do serious damage.
Trim nearby branches
If your roof is overshadowed with trees in any way, trimming the trees back can be a great way to avoid future problems. Not only will overgrowing branches drop leaves and small twigs into your gutters, but a snapped branch in a storm could make some very expensive mess.
Insulate your roof properly
Effective and functioning roof insulation is a tricky thing to get right. A roof needs to stop heat from escaping, but if not properly ventilated a roof can collect moisture in condensation. This lingering moisture can rot and weaken your roof from the inside, which then becomes a real problem. Regularly monitor your insulation and ventilation in your home to avoid these costly repairs.

At Resi, we strongly recommend hiring a professional whenever tending to your roof. Roofs are complex beasts and mistakes or oversights can be very costly. Here are some professionals you may need to consult:
Though most builders and contractors will have general roof knowledge, there may be situations where you need a specialist. Specialists will likely be required in complex situations, such as irregularly shaped roofs, particularly steep pitches or roofs with large amounts of damage.

Structural engineers specialise in the science and safety of structural strength, and their expertise may well be required in a roof works. Roofs are heavy things and need a lot of support to provide shelter safely, so it’s always good to get the opinions of an expert.
