Finding a Contractor:

How Can I Choose the Right Roofing Contractor?

Be sure to get a detailed quote from your roofer, and make sure it shows everything that was discussed on it. You should also ask for referrals and speak to some former customers. Make sure that the roofer cleaned up after themselves, finished the job when they said they would, addressed any issues in a timely way, and kept to the contract. Make sure that you trust whoever you hire to do the job correctly the first time.

To get the best deal, get a range of quotes from several roofing companies and ensure you know exactly what you are being quoted for. If you like the look of a particular product for your new roof, don’t be afraid to ask for it.

If my roof is leaking, do I need to get it completely replaced?

Just because your roof has a leak, does not mean it needs a complete re-fit. A leak usually stems from a loose or broken roof tile. However, a complete roof system failure, or a generally unsafe roof, will need a complete re-fit.


What are the warning signs that my roof needs replacing?

There are quite a few different signs that your roof is on its last legs. If you believe your roof is showing any of these signs, then it’s time to call in the experts.

Your roof has not been replaced in 20-30 years, which is the average life of an asphalt shingle roof.

Your tiles or shingles are cupping (the shingles turn upwards) or clawing (the edges stay flat but the middle starts to turn upwards).

There are entire tiles or shingles missing from your roof.

There are roof granules in your gutter.

Your tiles or shingles are cracked.

Light is coming through your roof and can be seen in your attic

The roof is sagging in an area, which could indicate a structural issue


How long will it take to re-slate my roof?

It really depends on how big the roof is. It could take up to three weeks on a standard semi-detached property.


Will I have to move out of my home while the roof is being repaired?

Only in very exceptional circumstances, such as when the roof is very structurally unsafe. Otherwise, you can stay at home.


How can I as a homeowner recognise when a roof system has problems?

Leaks are often the first sign that something is wrong. Make sure you inspect your roof and gutters twice a year. Look out for cracked, warped or missing shingles or excessive surface granules accumulating in the gutters – these can all be visible signs that your roof has a problem. Indoors you should look out for bubbled or peeling wallpaper, cracked paint, discoloured plasterboard or anything out of the norm. Remember, the longer you leave a problem the more expensive the solution is likely to be.


Can I do work on my roof myself?

Most work should not be done by you. Even cleaning gutters can be dangerous. And please don’t use a jet wash to clear moss off your roof (it may not be dangerous for you but your tiles won’t like it). Professional roofing contractors should carry out most works as they are trained to safely and effectively repair or replace roofing systems. You could damage or further damage your roof by attempting to carry out the work yourself and possibly cause yourself injury doing so.


What should I do if I notice cracked tiles on my roof?

Cracked or broken tiles are unfortunately a common occurrence. When they do occur we recommend that they are removed and replaced as soon as possible to minimise damage to sub-structures. When replacing damaged tiles, it’s important to use tools such as cat ladders and crawl boards to spread out your weight so as not to damage any more tiles. We also recommend that you do not put yourself in any danger, so call a professional roofing service (like us!) to ensure your safety and that the job is done properly.


Do I need planning permission to re-roof my property?

In normal circumstances, it’s unlikely you’ll need planning permission to re-roof your house or to insert lights or skylights. The permitted development rules allow for alterations subject to the limitations and conditions below:

Any alteration to project no more than 150 millimetres from the existing roof plane.

No alteration to be higher than the highest part of the roof.

Side facing windows to be obscure-glazed; any opening to be 1.7m above the floor.

The permitted development regime for solar panels has different limits on projections and in relation to protected areas.

There are exceptions. If your house is within a conservation area or world heritage site, then there are stricter guidelines to follow.


Q: How does rain run off a flat roof?

A: Flat roofs are generally built with a slight incline so that rainwater can drain away into the gutters. Basically flat roofs aren’t always absolutely flat.


Q: How do I maintain my flat roof and what should I inspect?

A: Inspect the roof twice a year in March and November – ideally soon after rain or snow so you can check that the water is draining away. Before you attempt any inspection ensure that access is safe. If you’re unsure of the condition of the deck do not step on the roof. If you do need to step on the roof use a sheet of OSB3 or Plywood to distribute your weight evenly.


Q: My flat roof is leaking. Can it be repaired, or do I need a whole new roof?

A: If it’s obvious what’s caused the leak, and the rest of the roof is okay, then a minor repair is probably okay. This sort of random patching up isn’t guaranteed though. That said, if the whole roof is in poor condition, or you need a warranty, then a full replacement (or possibly an ‘overlay’ – see below) is the best thing to do.


Q: How do I find a reputable contractor?

A: Asking around for local roofers with a good reputation in the area is a good place to start. Ensuring they are members of the appropriate trade association or the competent Roofer scheme is also advisable.


Q: The contractor wants me to put insulation onto my roof – do I need to? If so, where does it go?

A: Thermal Insulation reduces heat loss through the roof, and saves energy during the winter. It also keeps your house cooler and more comfortable in the summer. This is now a requirement of Building Regulations (Part L:2006). If you are putting up a new building or a new extension, or you’re repairing or replacing more than 25% of an existing flat roof area, then YES – you do need to upgrade by including a layer of thermal insulation.
