Roofer FAQs

What is the best commercial roofing material?
The best commercial roofing material for your building will depend on the size and type of roof you have as well as your budget. A lot of commercial buildings have flat roofs, but some have pitched roofs. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively. Pitched roofs are much steeper and are made using tiles or shingle. Our top choices for commercial flat roofs would be fibreglass or EDPM rubber. Both of these materials will set you back around £80-110 per square metre, making them some of the most expensive flat roof materials, but they’re strong and durable. A fibreglass roof consists of a cut glass fibre mat that is pressed on the roofing frame, then resin is poured and rolled over the roof before a topcoat is applied. An EDPM roof involves laying an EDPM rubber membrane on the roof surface then gluing it down and coating it with a contact adhesive. For pitched commercial roofs, our top material would be concrete tiles or metal. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Metal roofs have been used for over 50 years and today’s modern systems are extremely strong and allow for structural or thermal movement. Aluminium roofs will cost between £40-75 per square metre, plus installation. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively.

For pitched commercial roofs, our top material would be concrete or clay tiles. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Clay tiles cost as little as 50p to £2 each and can last over 50 years, but they are heavy so if your commercial roof isn’t already, it will need to be reinforced.

why do roof tiles slip?

Why Do Roof Tiles Slip?

Despite being our first line of defence against the elements and covering the most valuable assets we possess, it’s shocking the reason why most roofs go unnoticed for years. However, when a damp patch suddenly appears on the ceiling or water starts to leak into our home, the condition of our roofing suddenly becomes of huge importance to homeowners.

In the UK, we get a fair share of harsh wind and heavy rainfall across the year which over time can lead to a plethora of roofing issues. One of the most obvious to identify is when roof tiles slip. If you’re also facing the same challenge, then you’ll most likely be interested in knowing the reason behind this occurrence. In this article, we’re going to take a look at some of the reasons why roof tiles slip.

Roof tiles can slip as a result of a corrosion of the nails that’s in place to secure your tiles to your roof. This happens especially during strong storms, whereby several roof tiles can be dislodged by rain and winds. If the affected tiles are just a few, then it may actually be a little issue to resolve. However, there are also times that the tiles slippage can be caused by a more serious issue. What’s more? You can also discover slipped roof tiles if the wood of your roof is corroded or weak. However, this applies a lot more to older homes than new or recent constructions. Any of the above reasons may be the main cause of your roof tiles slippage, but if you really want to know the exact cause for sure, you’ll have to call in a professional roof company to inspect your home.

How to clean soffits and fascias?

As long as you can access them safely, it’s fairly easy to clean soffits and fascias. Using a sponge and warm water to scrub them is a good way to get off most types of dirt. You might want to add detergent or bleach to the water to make it more effective.

Once you’ve scrubbed your soffits and fascias, rinse them with clean water to make sure you’ve got all of the dirt and detergent off.

What is a pitched roof?

A pitched roof is a type of roof that is defined to have a sloping surface that has an angle that is greater than 20 degrees. Pitched roofs offer a more classical appearance. They remain the most communal and effective answer in wet and cold weathers to guarantee all-out protection.

Eaves

In the roof, the lower part of the inclined roof which is prominent outside the external face of the wall. The chief purpose of eaves is to pour the rainwater from the roof straight on the exterior wall. It also provides protection from sunlight. Eaves are sometimes decorated to an architectural beauty.

Gable

The Three-sided higher part of the wall at the end of a ridge roof.

Flashing

A band of impermeable material, typically metal, used to eliminate water from the intersection between a roof covering and another part of the structure. Flashings are provided to stop moisture from inflowing the wall and roof through joints in copings, parapet wall, and other infiltrations through the roof plane.

Hip

The Hip is defined as the exterior angle, which is generally greater than 180 degrees, which is formed at the inclined ridge of the roof slopes.

Ridge

The ridge is defined as the horizontal intersection made by the rising roof surfaces that are inclined in opposite directions.

Purlins

Purlins are the horizontal members which are laid on the principal rafters which help to support the common rafter of a roof. This is usually done when the span is large. Purlins are made from wood or steel. The top surfaces of the purlins intend to be unvarying and plane.

Fascia

This is the wooden board that is fixed to the feet of the common rafter at eaves. The Fascia helps the lowest ends of the roof covering material to rest on it.

Rafter

One of the major structural components of a pitched roof is a rafter. The rafter generally begins for the support of the roof to the ridge or hip. The purlin is supported by equally spaced rafters used side by side.

How to repair a fibreglass flat roof?

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.

do you need felt under roof tiles?

Do You Need Felt Under Roof Tiles?

Before now, roofing felt were mainly incorporated to serve as a temporary waterproof roof on a building which would later on be changed for the permanent solid tiles or slate roof. This is due to the fact that rebuilding a roof can be time consuming taking a few number of days, the roofing felt would be used to protect the structure as well as the property it contains by acting as a barrier between the house and the harsh elements such as rain, wind, snow, sleet and more, while also providing minimal insulation until the structure is complete.

However those are in the olden days, in recent times, roofing felt ( also referred to as breathable roofing membrane or breathable felt) is now being used to create a safe and waterproof roof which is long lasting and will protect your house, properties as well as other outbuildings for a long period of time while also complying with the Building Regulations. So to answer the question - yes, you’re going to need felt under roof tiles as it has been made mandatory by building regulations.

Now let’s take a look at the different functions served by felt.
