Just Bought a House With a Mossy Roof?
Many people buy a home knowing the roof needs some attention. The survey may have mentioned moss, the gutters may have overflowed on the first rainy day, or the roof simply looks tired in the sunshine. Knowing what to check first and in what order helps you spend sensibly on your new home.
Start with the survey
Re-read what your survey said about the roof and rainwater goods. Surveyors often note moss, recommend clearing gutters or suggest further investigation where moss hides the tiles. Those notes are a useful starting list.
Share the relevant section with us when you enquire so we can see what was raised.
Check for leaks first
Before thinking about appearance, check the loft on a bright day for daylight and on a wet day for drips or damp timber. Look at upstairs ceilings for stains. Any active leak takes priority over cleaning.
Our roof repairs page covers the minor repairs we carry out.
Look at the gutters
Gutters on a house that has been empty or on the market for a while are often full. Watch them in rain: water spilling over, plants growing and dry downpipes all point to blockages. Clearing them is a quick win.
Our blocked gutters page explains a clearance.
Cleaning or repair?
If the tiles are sound under the moss, cleaning and a few targeted repairs are usually the proportionate answer. If tiles are failing widely, replacement may be worth discussing. Our roof cleaning vs replacement guide helps.
A roof inspection with a photo report gives a clear picture before you decide.
The order of work
Deal with any leaks, then the roof, then the gutters, then walls and paving. Moss removal sends debris into gutters, so they are cleared afterwards. Patios and driveways are best done last.
Our exterior cleaning order guide sets out the sequence.
How the roof is cleaned
Moss is removed by hand, working with the tiles, then a soft wash and biocide where suitable deal with algae and slow regrowth. We never pressure wash roof tiles. Gutters are cleared afterwards.
Our moss removal page explains the method.
Getting to know your roof
In the first year in a new home, watch the roof and gutters through the seasons. Note where water overflows in heavy rain, where leaves collect in autumn and which slopes stay damp. That knowledge helps plan maintenance sensibly.
Take photographs as you go, with dates.
Previous owners' records
Ask the sellers or their agent whether there are records of roof work, gutter clearances or repairs. Knowing when the roof was last cleaned or repaired helps.
If there are none, a first clearance and inspection give you a baseline.
Budgeting for the first year
New homeowners often face many costs at once. Prioritising leaks first, then gutters, then the roof, helps spread spending sensibly. Cosmetic work can wait if money is tight.
We will tell you honestly what we think is urgent and what can wait.
Neighbours as a guide
Look at similar houses nearby. If neighbours' roofs are clean, ask who they used and how the roof looked before. If theirs are mossy too, orientation and trees in the area may explain it.
Similar houses built at the same time tend to have similar roofs and gutters.
Planning ahead
Once the roof and gutters are sorted, a simple routine of yearly checks from the ground and gutter clearance on a sensible cycle keeps things in order.
Our roof maintenance schedule guide suggests a routine.
Flats and leasehold homes
If you have bought a flat, the roof and gutters are usually the freeholder's or management company's responsibility. Report concerns to them rather than arranging work yourself.
Your lease sets out who is responsible for what.

Frequently asked questions
My survey mentioned roof moss. Is it urgent?
Usually not an emergency, but thick moss can lift tiles and block gutters. Check for leaks first, then plan cleaning.
Should I clean the roof or gutters first in a new house?
Check for leaks, then clean the roof, then clear the gutters, because moss falls into them during removal.
Can you work from my survey report?
Yes, share the roof section with us along with photographs and we will explain what we would do.
What should I prioritise in a new house?
Leaks first, then blocked gutters, then roof moss. Cosmetic work can follow when it suits you.
Who is responsible for the roof on a flat?
Usually the freeholder or management company. Check your lease.
