Leaks at the joins are usually a leadwork problem
Lead flashings seal the gaps where your roof meets a chimney, a wall, a dormer or a roof window. Properly fitted, lead lasts for decades. The trouble is, a lot of what we find is torn, too short, cheap flexible flashing, or simply smothered in mastic.
We strip out the failed flashing and replace it in code 4 lead, dressed properly and fixed securely into the brickwork.
What we do
- Chimney flashings, soakers and back gutters
- Abutment and step flashings on extensions
- Lead valleys, or dry valleys where they suit better
- Bay window and porch roofs
- Roof window flashing kits
- Replacing flexible flashing and mastic bodges with code 4 lead
Every job comes with a written guarantee, and we're fully insured. We've been working on roofs across Doncaster and South Yorkshire since 2014.

- Damp where a roof meets a wall, such as an extension or bay

Kitchen leak from a torn abutment
The lead where the kitchen roof meets the house was torn and hadn't been fitted correctly. We replaced it.
Split step flashing replaced
The step flashing had split and the seal into the brickwork had failed. We replaced it and checked the roof for other breakages.
Two new dry valleys
We stripped out the old valleys on the front gable and installed new dry valley troughs on both sides.
What our customers say
Just had complete new roof, fascias and soffits, excellent job from start to finish highly recommended Jamie and the team, they were really up against it as the weather was extremely unkind lots of rain!! But they got the job done and and site cleared. Roof looks great thank you.
Replaced Soffits, fascia’s and guttering over 2 days due to the unpredictable weather. Josh's team did an excellent job, it’s made the house look almost new again. Would definitely use this company again. Thanks Apex.
Hassle free process start to finish, honest and good value quote, no added extras, good set of lads who grafted in damp and cold, good time keeping and really happy with the finished product. Highly recommend an all round good local company.
Common questions
Why not just seal it with mastic?
Mastic and flashing tape are short-term fixes. They crack and peel within a year or two, and the leak comes back. Lead, fitted properly, lasts decades.
What is code 4 lead?
It's the standard thickness for most roofing flashings. It's thick enough to last and flexible enough to dress neatly into place.
Can you fix a leak over my kitchen extension?
Yes. Leaks where an extension roof meets the house wall are usually down to the abutment flashing, and that's a straightforward fix.
