Roof valleys and gullies are an integral part of your roof. These are channels running up and down the angles and “folds” of your roof. Unless you have a very simple roof design, you’re likely to have at least one roof gully or valley on your roof. Unfortunately, these areas are particularly vulnerable to damage, which can compromise the water tightness of your roof and put your home at risk of water damage. Here, we’ll explore some of the common reasons why your home may need roof gullies and valley repair.
Properly flashed roof valleys should always have an ice and water shield. This should be installed with the roofing felt secured over it. If your shield is missing, it can allow water to infiltrate your home and cause damage. You can check if your roof has a shield by looking in your attic. Look through the spaces in the roof boards to see where the valley is located. If you have multiple valleys in your roof and all are missing shields, this can be a significant problem. Installing new shields will involve removing the tiles on both sides of the valley and replacing them after the shields have been installed. If you have an older roof or there are other areas of damage, you may need to consider a new roof. However, our recommended experts can advise you if a repair is feasible.
Tiles do not have an unlimited lifespan, and as they start to age, cracks and fissures can be created that allow moisture to pass through. When new or well-maintained tiles create a water barrier, bit exposure to wind, snow, rain, and sun can allow the tiles to shrink, expand and break apart. Eventually, pieces of tile can be blown off or washed off your roof. When this occurs, the underlying roof materials are exposed, creating a real possibility of leaks and very costly problems. Since valleys and gullies are particularly vulnerable to weather damage, when your tiles are getting old, it is likely that you’ll need professional repair services.
During installation, if nails are improperly placed, it can accelerate the aging process of tiles and other roofing materials. When roofing nails are left within the seam area of a roof valley, they can allow moisture to be drawn through. Additionally, if tiles or slates are nailed too close to the valley, tension is created, and this causes premature wear, cracking and tile failure. Roofing nails should be placed six to ten inches from the valley seam to reduce the pressure on all the roofing materials.
Roof gullies and valleys are prone to collecting leaves, twigs, tree branches, dirt, and even ice or snow. This accumulation of debris interrupts the natural downward water flow, and water will start to become trapped and pool. This leads to seepage and can encourage the valley or gulley materials to start to deteriorate. Removing the debris regularly will allow proper drainage and protect your roofing materials.

We had been trying for weeks to have a hole in our roof mended. We asked for a call back on the Thursday. They called us back within a few minutes and came and fixed our roof Saturday. Will definitely use them for any other roofing repairs
Great service from Alan and his team. Kept us informed throughout. Would rehighly recommend.
Very pleased with the new roof to our extension. Excellent communication - came out quickly to provide a quote - work done speedily and efficiently in very cold weather. Thank you.
Small job fixing ridge tiles. Good quality work, done promptly and at a fair price.
On my journey to find what is the issue with my roof Michael came recommended by another very high ranking professional who deemed its best to get some roof work done before I attempt to clean moss. I have nothing but kind words to describe Michael's professionalism, knowledge and skill. He has a very sharp eye and can pinpoint anything wrong with the roof and is incredibly honest and clear on what options we have on how to attempt to do the work. He provides an update every day on what is done and what is left and is incredibly clean and tidy when doing the work. He has so much compassion of the family situation and provides options for work to be done to suit the family budget. He has been so kind, knowledgeable, and honest with us that he has made something as devastating as roof works in 2 months of moving in, for a first time buyer, something manageable. He is always on time and has prioritised to do work even when the temperatures were below 0 just to make sure our roof wasn't leaking with the bad weather saving us a lot of potential damage. He is very trustworthy and I would recommend him and use him again if needed.
I contacted L&M roofing on Saturday, the problem with the damaged chimney, we met on Sunday, we agreed on the work, on Monday it was already done, before and after photos, efficiently and professionally. Thank you I'm waiting for the first heavy rain 🙂
We lost a tile overnight in the recent storms - gave him a ring when we noticed it (on a wet & windy Saturday) - he was here within the hour and job completed 10mins after arriving. He was almost too embarrassed to charge us - but we were happy to pay for his service (and obviously did). Great guy and a great job done. Highly recommended - and such a nice chap as well. We will definitely use him again.
I can't praise Steve and his team highly enough. Exemplary standard of workmanship, courteous, punctual, tidy, considerate and reasonably priced. The work (replacing soffits, fascias & guttering) was completed on time, on budget and to the highest standard. The site was thoroughly cleaned before they left. I would unreservedly recommend giving Steve the chance to quote for your job and am sure that you won't be sorry.
Very professional, Very happy with the end result. Would recommend 100%
Amazing from start to finish
Would recommend SDB building. Communications are always excellent, and the team deliver high quality works on the promised timescale.
Quick and efficient response to the major issue found when doing work, communications were excellent throughout the work, photos supplied of completed work which is very helpful. While not the cheapest or most expensive, work completed looks 5*, it was not rushed.
I needed some repairs to roof & drainpipes adjusting. Steve came as agreed, gave a competitive quote, was friendly & helpful offering good sound advice. His colleagues tidied up and seem to have resolved the problems. Thank you to him & his colleagues
Very helpful and thorough did a brilliant job and very friendly.. Would definitely use them again highly recommend
The work was delayed by weather but Steve kept me updated, and I was completely happy with end result
Prompt reply and dealt with problem immediately, and corrected problem which was left by original company! Thank you
Steve turned up as promised and the job was carried out quickly and efficiently. I would definitely use again!
Steve and the guys did a great job replacing the valley, installing an eaves tray and felt replacement on the chimney and chimney flaunching to name just a few of the repairs. High quality job - I can tell by the photos they undertook before and after. Reliable time keeping, they worked hard, kept tidy and above all the communication was excellent. I have used them several times before for different building jobs and they always provide a high level of service which is customer focused. Highly recommended.
Great team of guys who responded to our urgent repair needs. Steve was happy to talk us through the issues he could see and the options and costs of correcting them, before starting work, so there were no surprises. Work was completed on time and to a high standard.
Needed a Velux window removed from the roof and also some repairs. Team were professional, efficient and got the job done in a day. Will be using them again and would highly recommend if you need work done
