Why Autumn Is the Critical Window
Shropshire's wet season runs from October through March. The combination of heavy rainfall, overnight frosts and occasional snow loading means that any roof defect that exists going into winter will be significantly worse by spring. A minor cracked tile in September becomes a saturated rafter by January. A partially blocked valley in October becomes a leak into the bedroom ceiling by November.
The good news is that autumn inspections are straightforward, most issues are cheap to fix before winter, and the cost of prevention is a small fraction of the cost of water damage repair.
Frost cycling — daily freeze-thaw during cold spells — can convert a 2mm crack in ridge mortar into a 6–8mm gap over a single Shropshire winter through ice expansion, creating tile loss risk in the first significant wind event of spring (British Standard BS 5534:2014 + A2:2018, Slating and tiling for pitched roofs and vertical cladding).
The Checklist: What to Check and How
1. Tiles and Slates — Ground-Level Survey
Stand back from each elevation of the property and look carefully at each pitch in good light. You are looking for:
Tile and slate warning signs
- Any tile or slate sitting lower than its neighbours — the classic slipped tile
- Gaps where tiles are missing entirely
- Cracked tiles visible from the ground (particularly ridge and hip tiles)
- Patches of darker colouration on the roof surface — often indicates wet underlay or a tile that has lifted
- Granular material or fragments in the gutters after rain — indicates surface erosion on concrete tile
2. Ridge and Hip Tiles
Ridge tiles on Shropshire properties take the most weather punishment of any roof element. Check from the ground that the ridge line is straight and continuous, with no gaps or lifted sections. On hip-roofed properties, the hip cappings at the corners of the roof should also be checked for any that appear proud or displaced. A single ridge tile dislodged in a November storm can expose a linear gap along the apex that allows wind-driven rain straight onto the underlay.
3. Gutters and Downpipes
Blocked gutters in Shropshire's autumn are one of the most common causes of winter water ingress. Leaf fall from October onwards can completely block a gutter in a matter of weeks on properties with nearby trees. A blocked gutter overflows directly onto the fascia and soffit, saturating the eaves timbers and eventually finding its way into the roof void.
Check that all gutters are clear and draining freely, that downpipes are unobstructed, and that gutter brackets are secure with no sagging sections causing pooling. A garden hose run from an upper window will confirm whether downpipes are clear.
4. Lead Flashings
Chimney flashings and valley linings should be checked visually from the ground. Look for lead that appears to have pulled away from the mortar chase at the wall junction — this shows as a gap at the top edge of the flashing. On bay windows, check that the lead flat at the top of the bay has no visible cracks or lifted edges. Lead failures that are borderline in summer become active leaks as soon as sustained rainfall arrives.
5. Chimney Stacks
Use binoculars if necessary to check chimney stacks. Look for crumbling or missing mortar between bricks, cracked flaunching (the mortar cap at the top of the stack), or displaced chimney pots. A chimney stack with failed mortar pointing absorbs water with every rain event — in a frost cycle, that water expands and progressively forces the brickwork apart.
6. Flat Roofs
Garages, rear extensions and bay tops with flat roofing should be checked from above where safe to do so. Look for blistering or cracking on felt surfaces, standing water that has not drained 24 hours after rain, and any upstand areas where the roofing material has pulled away from the wall. A flat roof with minor blistering that is serviceable in summer may fail completely under sustained winter rainfall.
7. Loft Inspection
The loft inspection is the most revealing check on the list. Turn off the loft light on a bright day and allow your eyes to adjust. Any daylight visible through the tile covering indicates a gap or displaced tile. Look for damp patches on the underside of the underlay, rust staining from nail heads (indicates nail corrosion), and any sagging sections of underlay that suggest it has already held water. Check all timber surfaces for dark staining or soft spots.
Do not leave loft defects until spring
A damp patch visible in the loft in October will become structural timber damage by March if left unaddressed. Water ingress into roof timbers over a full wet season causes rot that is significantly more expensive to repair than the original roof defect.
What to Do With What You Find
Any defect identified during this check falls into one of three categories:
- Urgent — before first frost: Missing or displaced tiles, open ridge sections, visible daylight through the covering, active lead flashing failures
- This season: Cracked ridge tiles, partially blocked gutters, chimney mortar deterioration, flat roof blistering
- Monitor through winter: Surface moss on concrete tiles, minor hairline cracks on sound tiles, minor pointing deterioration on chimneys

Choosing the Right Contractor for This Type of Work
The most effective protection when commissioning roofing work of any type is insisting on a written, itemised quote from a contractor who can demonstrate both current insurance and verifiable trading history. A contractor unwilling to provide either — or who provides a quote that is too vague to allow comparison with others — should be treated with caution regardless of the price.
The standards that apply to roofing work in Shrewsbury are not exceptional. Physical survey before quoting, written fixed-price specification, stainless fixings, breathable underlay, correct mortar for the property era, and a written workmanship guarantee are normal expectations from a legitimate contractor. If a quote does not include these elements, ask why before agreeing.
What separates a reliable roofing contractor from an unreliable one
- ✓Physical survey — not a quote from the ground or from photographs
- ✓Written specification — materials named, not described generically
- ✓Fixed price — not an estimate or day rate
- ✓Insurance verifiable — NFRC certificate available on request
- ✓Payment terms — deposit plus completion, not full upfront payment
- ✓Guarantee in writing — period, scope, and what it covers
- ✓VAT shown separately — not hidden in the total

The most common source of post-job dissatisfaction in roofing is a mismatch between what the homeowner expected and what was actually agreed in the quote. The gap usually exists because the quote was not specific enough to define expectations on both sides. Getting an accurate, reliable quote requires the same steps regardless of the type of roofing work involved.
First, the contractor must physically access the roof before quoting. A quote based on a description of the problem, ground-level inspection or photographs is not a reliable fixed price — it is an estimate that will be revised once the work starts and the actual condition is visible. Insist on a physical survey as the basis for any written quote.
Second, the quote must specify materials. 'Quality materials' is not a specification. The tile manufacturer, profile, colour and product guarantee should be named. The underlay type should be specified as breathable, not generic felt. Lead work should specify the code weight for each application. Without this detail, the contractor can substitute cheaper alternatives without violating the terms of the quote.
Third, the quote should identify what is excluded as well as what is included. Access, waste disposal and VAT are the most frequent sources of unexpected additional cost at completion. A quote that includes scaffold erection and removal, waste disposal to a licensed tip, and shows VAT as a separate line item is transparent and trustworthy. A quote that omits these elements and adds them at invoice stage is not.
Pre-quote questions that clarify scope and protect you
- ✓Will you physically access the roof as part of this survey?
- ✓Can you name the specific tile and underlay you plan to use?
- ✓Is scaffold included in the price, and does that include removal?
- ✓Is waste disposal included in the price?
- ✓Will you show VAT as a separate line on the invoice?
- ✓What is the payment schedule — deposit, stage payments or completion?
- ✓What is the guarantee period and what does it cover specifically?
