Roof Leak Detection - How We Find Where the Water Is Getting In

· Absolute Roofing 247

Roof tiles and ridge checked during roof leak detection by Absolute Roofing 247 in Greater Manchester

A brown stain on the ceiling, a drip in the loft or a damp smell upstairs are all signs your roof may be leaking. The tricky part is that the leak on the roof is often not right above the mark inside. That is why Absolute Roofing 247 always starts with proper roof leak detection before carrying out a roof repair anywhere in Greater Manchester or West Yorkshire.

Why roof leaks are hard to find

When rain gets through a roof, it does not always drop straight down. Water can run along roof timbers, felt or the top of a wall before it finally shows on a ceiling. A damp patch in the bedroom might start at a cracked tile further up the roof, a gap in the lead flashing by the chimney, or a split in a nearby flat roof.

If a roofer only patches the spot above the stain, the leak can come straight back. Finding the real cause first saves you money and stress.

Common causes of roof leaks

On homes across Manchester, Stockport, Bolton, Leeds, Bradford and Huddersfield, the usual causes we look for are:

- slipped, cracked or missing tiles and slates

- loose or broken ridge and hip tiles

- worn or lifted lead flashing around chimneys, walls and dormers

- splits, bubbles or lifted edges on flat roofs

- blocked gutters and valleys, where water backs up under the roof

- storm damage after high winds and heavy rain

How our roof leak detection works

We look at the roof and the area around the leak, inside and out, and follow the likely path of the water back to where it is getting in. On hard-to-reach roofs, a drone survey can help us get clear photos without climbing up. Once we know the cause, we explain it in plain words and give you a free quote for the roof repair.

What you can do while you wait

If water is coming in now, keep yourself safe and limit the damage:

- stay off the roof, especially when it is wet or windy

- move furniture and belongings away from the leak

- catch drips with a bucket or bowl

- if water is near lights or sockets, switch off the power to that area if it is safe to do so
