Roof leak investigations for homes and businesses in Todd's Green
A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us and so do photos. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. If you’re worried about staining around the chimney inside and damp ceilings under a flat roof, we can find out what’s behind it, whatever the roof.
Many homes in small places like Todd's Green face open ground, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
Where we can’t see part of the leaking roof, the report says so. You will know exactly what was inspected and what wasn’t.

- Structural calculations (that’s a structural engineer’s job)

DIY checks: what’s safe
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
Common roof problems in Todd's Green
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can send that water under the coverings. The stain may appear well away from the valley itself.
Typical things we’re asked to look at include:
- Wet patches high on an inside wall
- Stains around a skylight
- Damp patches next to the stack
- Water that shows only in certain storms
Landlords with a home close to Stevenage station may find that tracing a leak quickly matters when a tenant is living with it.

Leaks and storm damage in Todd's Green
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Knowing the roof type helps narrow down where water may be getting in. About 3.5 miles south lies Knebworth House, a reminder of how long the area around Todd's Green has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
Take a building like The John Henry Newman School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if your home is one of the older ones nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
