The cost for a sun tunnel is affected by 5 key factors:

1. Tube size: Small areas or stairways can gain from a 10-inch size tube, whilst bigger rooms will require a bigger tube. The higher television size, the greater the price.
2. Kind of tunnel and also roof type: You can pick from stiff or flexible tunnels and also domed or flat roofing system panels. Each choice will have a different price.
3. Place: Where you stay in the country will certainly impact the price of your sun tunnel installation. Generally, the higher the living prices in your location, the greater the price of employing an expert will certainly be.
4. Length of the tunnel: Longer tunnels will be charged at a greater price than their shorter equivalents so whether the tunnel runs from the roof to the 2nd or very first flooring will certainly impact the sun tunnel price.
5. Ease of gain access to: Flexible tubes are fantastic for homes where sun tunnels do not run in a straight line from roofing to ceiling. The tubes can then be fitted around challenges in your loft space. Frustratingly, these alternatives do not allow as much light as stiff tubes and also due to their hard setup can be much more expensive.

If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system.

One of the most popular choices for roofing materials are roof slates. There is a number of advantages that a roof slate has, hey can be aesthetically pleasing, they can also increase the potential selling value of the house and many more. Slate is a sturdy and resilient material that delivers waterproofing physical characteristics to a pitched roof. Unlike other roof materials which absorb water slates do not. Therefore, slate is the most resistant towards freezing and water damage.

Find out the pitch of your roof

Before beginning with the fitting procedure, you need to figure out the pitch of your roof. The roof pitch commands how much overlap is essential with each slate. This has been made a lot easier than the early days with the advancement of technology.

Find out the required overlap

Once you’ve found out the exact pitch of your roof accurately, take a look at the slate producer’s description. Each manufacturer will propose the obligatory overlap in order to form a firm and safe slate roof.

Roll out the roof membrane

Firstly, guarantee your joists or trusses are clean of any sheards or old nails that could harm the membrane. You will now have to roll the chosen roofing membrane along the roof trusses. It is always wise to start from one of the bottom corners and keep rolling it along to the other corner.

Secure the roof membrane

Once the membrane has been moved out, use thump nails to protect one edge. You will now have to pull the membrane taut and carefully fix it into position. Do this before adding any nails across the membrane at points of intersection with the trusses for extra stability.

Batten placement

This is done to find the proper assignment of the battens. For this, you will need two full-sized slates along with an under eaves slate. Carefully position the battens on the top of the roof on the top of the overlay. Make sure not to fix them down since it will be easier to move them around and make any adjustments.

Fibreglass, or GRP, flat roofs are very durable and should last you years, but over time they can become brittle and you might see some cracks or holes forming. Luckily, you can repair a fibreglass flat roof and it doesn’t have to be too difficult. Cracks in a fibreglass flat roof If you notice long cracks in your fibreglass roof, you can often use a fibreglass crack sealant. Simply clean the area, squeeze the sealant into the crack, then smooth it off. If you want it to look neater, you could coat the entire roof with a restorative coating which will make it look new again. Hole in a fibreglass roof If you notice a hole in your fibreglass flat roof, you’ll want to get this repaired as soon as possible to avoid any rainwater getting into your home. There are lots of fibreglass roof hole repair kits on the market, both online and in DIY stores, so you shouldn’t have trouble picking one up. They usually contain a mouldable UV cured patch that you can stick onto the hole. It will harden and become instantly weatherproof, so is the perfect emergency repair solution. Fixing pin holes in a fibreglass flat roof Unfortunately, if you find pin holes in a fibreglass flat roof it’s often because the installer didn’t use enough resin during the fibreglassing process. Luckily, if you can’t get back in touch with the installer or you only notice after a few years, you can fix this yourself. Sand down the roof back to the clear resin layer. Clean the entire roof with acetone and reapply some GRP roofing resin. Ensure that all the pinholes are filled – you might need two coats.

Tar and gravel flat roofs are popular because the gravel weighs down the surface of the roof so it doesn’t blow away and it also protects it from sun damage. The tar makes the roof watertight, so you won’t get any leaks. However, sometimes problems occur and you’ll get cracks and leaks. So how do you repair a tar and gravel flat roof?

If you notice leaking coming through your flat roof, try to find the source of the leak. Since water can travel easily, it might not be where you think it is. The first place to check is the flashing, then any parts of the roof with gravel missing. Once you’ve found the crack, sweep away any remaining gravel and clean the area.

Apply a primer to the area and allow it to dry. Then, apply a tar and gravel roof patch that you can get from most DIY shops. Patch 2-3 inches around the damaged area, creating layers, and ensuring that there aren’t any air bubbles or gaps. Then you should cover the entire patch with gravel.

Before you try to repair a tar and gravel flat roof yourself, consider how much of the roof needs repairing. Professionals often say that if cracks and faults make up 25% or more of the roof, then you should look to replace it. It might be tempting to try and replace your tar and gravel roof yourself, but it’s best left to the specialists. They will ensure that your new roof is watertight and strong enough to withstand sun damage and storms.

A Velux window is a brand of roof window, but the brand is so popular that people often use the name to describe the entire type of window. They are windows that are installed at the same orientation and ‘in plane’ with the surrounding roof, and they’re usually installed at a minimum of a 15-degree pitch. You can buy roof windows that offer completely frameless internal views for a really clean look in your loft conversion, while some come with built-in shutters.

Velux windows aren’t to be confused with rooflights which usually refers to a glazed unit that’s installed on a flat roof. It might also mean a window that’s been installed on a pitched roof out of plane with the level of the tiling.

People also confuse roof windows with skylights, which normally can’t be opened or closed and are usually smaller than Velux windows. Skylights, therefore, only let daylight into the room whereas roof windows also help with ventilation.

If you’re using your loft as a room in your home rather than simply for storage, you must have a roof window installed. Skylights won’t be enough as they don’t allow for ventilation. It doesn’t have to be a Velux window – it can be any type of roof window. Luckily, they tend to come in standard sizes and they must be CE marked if they’re sold as a roof window, so they should be easy to find.
