Signs to look for

Signs a valley is letting water in

Leaves, moss and silt in the valley

Debris dams the water, and in a storm it backs up under the tiles either side.

Split or thin lead

Old lead valleys crack along the folds. The splits are hard to see from the ground.

A leak in a corner of the room

Valley leaks tend to show where two roof slopes meet, often over a bay or an extension.

How Shane does it

How Shane repairs a valley

He lifts the tiles along the valley, checks the boards and lead underneath and renews what has failed. Short splits are repaired; a perished valley is replaced in new lead or a GRP or dry valley trough, with the tiles cut and refixed along its edges.

A Brookwood family had a heavy leak in their guest room overnight and two quotes the same day for substantial work at a huge cost. Shane and the team found the problem was the valley and had it solved within a day, at a fraction of what they had been quoted.

Valley repair

I contacted Shane after a heavy leak in our guest room appeared over night , after two initial quotes the same day advising substantial work being carried out at a huge cost ! Shane and he’s team quickly discovered the issue with our valley within a day they had the problem solved at a fraction of what we had been quoted prior . 10 out of 10 service very professional and trustworthy and no issues since !! Thankful for now having a roofer we can trust for any issues in the future … thanks again guys !!!

Shane and he’s team was very prompt and assessed our roof to quickly navigate the leak in our flashing , had the works completed within 48 hours and helped us steer away from spending thousands on a replacement we was recommended by another firm , very happy transparency is key and we appreciate you ! Thanks guys

New roof installation

I had a lot of problems with my roof, it was leaking in a few different places. I contacted Shane, he was very helpful with explaining to me what was actually wrong with the roof and what needed to be fixed. When the work was carried out Shane and his team were very respectful , reassuring and hard working. They done a brilliant job, and I haven’t had any problems since.

Roof valley questions

What is a dry valley?

A preformed GRP or plastic trough that sits in the valley with the tiles cut to it, held by clips rather than mortar. It replaces mortar-pointed valleys that crack.

Lead or dry valley: which is better?

Both last when fitted properly. Lead suits older and slate roofs and conservation areas; dry valleys suit concrete tiled roofs. Shane explains which suits yours and prices both if you want to compare.

How long does a valley repair take?

Most valleys are repaired in a day. The Brookwood valley in the review above was solved within a day of Shane finding it.

Leak, slipped tiles or a roof you are worried about?
