New roof

How do you know you might need a new roof? It’s actually easier to tell than you might think. There are some tell-tale signs that let you know when there might be a problem. Not all of them mean an entire roof replacement is going to be necessary. Repairs can be made if the rest of the roof is largely in good shape. If you need to inspect, we recommend going out to the road below and taking a picture at high resolution with your smartphone. You can then blow it up and inspect things in detail. Don’t get out on your roof yourself, it’s too risky, simply ask us to do it. We have the equipment needed to make it safe and we are really experienced and know where to walk.

With a flat roof, watch out for signs of water pooling. On the inside of your home, water entry of some kind in the upper levels or patches on the top ceilings are the first signs to look out for. You might also find discoloured patches on the ceiling. Don’t ignore them. They could mean a loose or missing tile, or they could be a sign of a more serious problem.

If you have an attic, go up there carefully and check to see if you can see any light coming in from the tiled roof area. If there is, give us a call and ask for help. Don’t leave it, it gets harder to repair if damp has been coming in for a time. Small water-marks and mossy or greenish mouldy patches can be a sign too. The work involved making a lip and reboarding the back section. The whole area within refelted using high tensile material which should be good enough to last at least 25 years.

Inspect your photos. Look for obviously slipped or missing tiles. That’s another problem you should not just leave, as water ingress can damage your timbers and cause bigger damp and rot problems in the roofing structure. If you see missing tiles, call us. They are usually not difficult to repair. If you have a very old roof, you can expect missing tiles to be possibly a sign of nail fatigue, that will mean a new roof is going to be required. After 100 years all the nails can be fatigued. We will tell you straightforwardly whether you are in for a small repair or a bigger one.

Check your photos again for signs of mossy areas or mouldy areas. If there are lots of them a new roof may be required. A few mossy areas may just mean smaller repairs.

Over time these tiles will go soft erode and slide off with nail fatigue

Then blow up the details again and check the brickwork in the ridges and side walls. Check the chimney too. We are experts at repairing brickwork and renderings around these areas so if you see any pieces have fallen off, or if there are cracks, or parts are leaning to one side, call us right away or use the contact form on this website.

Go to a top window and look at the gutters. If there are pieces of brickwork or pieces of tile in the gutters, call us in, it’s a sign something is wrong with the roof. If any of the guttering has fallen off, ask us for a quote to fix, don’t leave it as falling water will damage the sides of your building over time and cause damp to appear in the inner walls eventually.

A natural slate roof weathered and needing replacement

This picture show the natural slate roof weathered and old and in need of replacement. These roofs can last over 100 years, but like everything in life, they need replacing after  along period of  time.One of the work in progress photos shows us stripping back the old roof for inspection. In this case, no timbers needed replacing -however we topped up the insulation to current LABC requirements. As you can see there is no need to completely empty the loft as we were able to move things around to accommodate the work.No timbers needed replacing however we topped up the insulation to labc requirements.

This is as close to Welsh slate in its appearance, which can be useful if you have another area of roof which needs to be matched. The photograph also shows new hips and new ridge tiles which we fitted to match.

These dormer constructions can sometimes leak over time because the zinc will need renewing. In this case the soaker underneath needed replacing which we did. Symptoms to watch out for include leaking around the edges internally.
