Pre-purchase roof surveys in Harmer Green

About our pre-purchase roof survey in Harmer Green

The best time to book is once your offer has been accepted and before you exchange contracts. At that point you can still ask questions, because nothing is binding yet. We survey seven days a week, which helps when a sale is moving quickly. Basic reports arrive within 48 hours, Standard within 24 to 48 hours and Premium the same day. Common reasons to book are flashings that have lifted or split and roof slopes that look uneven or sagging, on gutters and downpipes, clay and concrete tiles and chimney stacks.

Somewhere as small as Harmer Green, older cottages, farmhouses and converted buildings often sit beside a few newer homes. Village roofs can be clay tile, slate, stone or even thatch on some older buildings. Whether you are buying or have just had a roof replaced, each material has its own checks. Older roofs may also have old felt underlay or none, and fixings that have done a long stint.

After the visit, you get a photo-illustrated written report, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Roof by roof

Lead flashings and valleys

Many leaks start at a flashing, so we check each one closely. Any that need attention are photographed and explained.

Natural slate

Good slate is one of the longest-lasting roof coverings, yet the nails that fix it frequently give out first. Slipped or missing slates are a sign of ‘nail fatigue’.

What a pre-purchase roof survey looks like in Harmer Green

Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new. The wider area around Harmer Green has a long history of building, with Digswell House about 1.5 miles south-west. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.

Take an older house close to Digswell Village Church: ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges. Landlords with a home close to Welwyn North station may find that a survey before purchase, or before signing off a new roof, saves surprises once a tenant moves in.

Harmer Green is about 2 miles north of Welwyn Garden City, in Hertfordshire.

The survey, step by step

We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours on an ordinary house, with bigger or more complicated roofs taking longer. Around Harmer Green, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.

  1. You book once your offer is accepted and tell us the address and your timetable.
  2. We arrange access with you, the agent or the seller.
  3. The roof is inspected from each safe vantage point, inside and out.
  4. Coverings, ridges, valleys, flashings, chimneys and gutters are checked and photographed.
  5. Your report arrives by email, with photos and recommendations prioritised by urgency.

How to prepare

  • Unlock side gates and any roof access doors
  • Note where any stains or damp appear
  • For flats, make sure roof access has been agreed

Tips that help

You don’t need to be a roofer to help. What helps most:

  • Ask for any paperwork for recent roof work
  • Notice patches of new decoration in top-floor rooms
  • Tell us your exchange date when you book
  • Pass the findings to your conveyancer

If you want quotes for the work, roofers can work from the report. The photos show the defects and where they are, which makes quotes easier to compare.

Every so often, check the loft with a torch, keeping to boarded areas. Damp patches, daylight through the roof or water stains on timbers are worth noting. Take photos so you can show whoever looks at it.

Prices for pre-purchase roof surveys in Harmer Green

The price reflects the time and kit the roof needs. The main factors are:

  • Roof area
  • The number of roofs, including extensions and garages
  • How tall the building is and how easy the roof is to see
  • If the survey needs thermal imaging or a drone

We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. The price for your roof depends on its size, access and what you’d like to know.

Getting in touch

The more you tell us, the easier it is to price the survey. When you contact us, tell us:

  • Dates you are working to, such as exchange
  • Access details, like a loft hatch or a shared roof
  • Pictures of the roof from a safe spot, if you have them
  • Why you want a survey: buying, a leak, a storm or new work

A quick phone call is typically the easiest start: call 07833 053749 or send us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.

Landlord and commercial surveys in Harmer Green

For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.

Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photographs included.

Your questions about pre-purchase roof surveys in Harmer Green

Is my home in Harmer Green listed or in a conservation area?

For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.

Do you cover smaller places like Harmer Green?

We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.

Can I take the findings back to the seller?

Yes. You might ask for work to be done, ask questions or ask for a change to the price. The outcome is between you and the seller, so we can’t promise any saving.

Is this an asbestos survey?

No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.

Do you need to go inside the property?

Ideally, yes. We look in the roof space where there is safe access, and upstairs windows give useful views. Access is normally arranged through the agent or seller.

What insurance do you have?

Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.

Does someone need to be in?

Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.

Why it is worth a survey now in Harmer Green

A mortgage valuation isn’t a roof survey. It looks at whether the property is suitable security for the loan, not at the condition of each slate and flashing. Our survey is done for you. For an older or listed building in a place like Harmer Green, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.

All our prices include VAT. Our price is from £150, including VAT. You’ll know the price for the job before you book.
