Buying or selling a house: have the roof inspected

The roof is often the biggest hidden cost when buying a house.

At a viewing, almost everyone looks at the kitchen, the bathroom and the garden. Hardly anyone looks at the roof. Yet that is often where the biggest maintenance cost lies. An inspection gives you an honest picture before you sign or before you put your house on the market.

These are the points I look at.

Four points in a roof inspection

1

The roof covering. Porous or shifted tiles, moss, blisters or cracks in bitumen and EPDM.

2

The junctions. The chimney, ridge, valley gutter and roof windows are where a roof starts leaking first.

3

The gutters and downpipes. Rusted through, blocked or sagging often means damp damage to the wall and the eaves.

4

Insulation and ventilation. A roof without good ventilation or with wet insulation causes damp problems in the attic.

“As a buyer you know what you are buying, as a seller you can negotiate without surprises.”

Fouad, owner of Astrodak Service

For buyers and for sellers

As a buyer, you can have the roof assessed before you sign, and use the result to negotiate or to add a condition to the contract. That is cheaper than a surprise after you get the keys.

As a seller, an inspection shows that the roof is in order, or you see in advance what still needs doing. That prevents arguments in the final stage. Also read repairing or replacing a roof.

Have the roof assessed

I come by with my colleagues with no obligation, we look at the roof and tell you honestly what condition it is in and what needs doing. You get a fixed price up front for the repair.

What happens if you skip it

1

A surprise after the purchase. A leaking roof or wet insulation often only comes to light after the handover.

2

No room to negotiate. Without an assessment you cannot back up why the price should be lower.

3

Higher costs. A small defect grows into a bigger problem if nobody looks at it.

4

Arguments when selling. A buyer who finds a defect themselves often asks for a discount.

How I work

Together with my colleagues I go over the roof, check the covering, the junctions, the gutters and the ridge, and where possible look at the attic from the inside. Afterwards you hear what is in order and what needs attention.

You get honest advice, with no pressure to have anything done straight away. Also read how often you should have a roof inspected.

What you can do yourself

Look up during a viewing: missing tiles, moss and a sagging roof slope can be seen from the street. In the attic, look for damp patches, see mould in the attic.

Ask the seller about the most recent roof work and any guarantees.

Frequently asked questions about a roof inspection when buying a house

The roof is an expensive maintenance item. An inspection shows whether the roof will last for years yet or will soon need attention, so you know in advance where you stand.

The roof covering, the junctions at the chimney and ridge, the gutters and downpipes and, where possible, the attic from the inside.

You can. With a clear assessment you have something to back it up if the roof needs work.

Yes. An assessment in advance shows that the roof is in order or what still needs doing.
