Roof Cleaning in Alexandria, IN

Black streaking, moss and lichen taken off asphalt shingle at under 100 PSI, without stripping the granules that make the shingle a roof. We do this work throughout Alexandria and the rest of Madison County on the same terms as everywhere else: a free estimate, most of the time without a site visit, and a method chosen for the surface rather than for the schedule.

Under 100 PSI, and never a wand

Granules are the roof's sunscreen. Strip them and the asphalt underneath is exposed to ultraviolet light, and the shingle begins to fail. A pressure wand strips them by the handful, and the damage does not show up for two summers.

We apply a cleaning solution, let it work, and rinse at a pressure that would not disturb a leaf. The organism dies, the roof comes back to its own color, and the shingle is untouched. It is also the method every major shingle manufacturer points at in their own maintenance guidance.

Black streaks are alive, and that changes the job

The dark staining running down a roof is gleocapsa magma, a cyanobacteria that feeds on the limestone filler in modern shingles. It is not dirt and it will not wash off. It spreads downward with the water, which is why the streaks run in lines and the north slope is always the worst.

Killing it takes a cleaning solution and dwell time. Every roof we clean in Alexandria is done that way, at a pressure that would not disturb a leaf.

What is included

• Black streaking, algae, moss and lichen
• Under 100 PSI, chemical dwell, never a pressure wand
• Asphalt shingle and other applicable roofing systems

Alexandria price. $600 – $1,500+ for standard residential roof. That is a budget range rather than a final number, because size, stories, access and how long it has been all move it. Every range we publish is on the pricing page.

What a wand does to vinyl siding

Vinyl laps are built to shed water running down them. A pressure wand aimed upward drives water behind the lap and into the wall, and on older siding it will chalk, crack or unseat a panel outright.

Nothing about a Alexandria address makes that different, so siding here gets the same treatment as everywhere else: solution, dwell, and a rinse under 500 PSI.

Roof Cleaning around Alexandria

Alexandria sits in Madison County and carries house washing, roof cleaning and concrete as standing services. When we are here we are usually also in Anderson, Pendleton and Elwood, so a job booked alongside one of those is easier to schedule and cheaper to run than a single trip.

Anything on our list that Alexandria does not have its own page for can still be done here as part of a visit. Ask when you call and the estimate will show it both ways.

Working from the ground instead of off a ladder

Most of what we do is reached from the ground: extension wands for siding, a water fed pole for upstairs glass, and low pressure application for roofs. Fewer ladders means fewer marks on the gutters, less risk, and a faster job.

Where a Alexandria property genuinely needs someone up there, we are insured for it and we will say so in the estimate rather than at the door.

Insurance, and why it matters on a roof

We are fully insured, and on roof work that is not a formality. Someone on your shingles with a solution and a hose is either carrying coverage or they are carrying it on your homeowner policy.

Ask any company for a certificate before they start. If it takes more than a phone call for them to produce one, that is the answer.

What a wash actually buys you

Algae is airborne and it will come back. What a clean buys is the reset, plus the years of surface life that the growth was quietly taking: moisture held against shingle, roots in the granule bed, staining working into porous concrete.

A Alexandria property on a one to two year rhythm never gets to the state where the job is expensive. That is the whole economics of it.

Why the driveway is where the difference shows

Concrete is the one exterior surface that genuinely wants high pressure, and it is also where a rented machine gives itself away. A wand cleans in stripes, because the fan is narrow and the overlaps show up the moment the slab dries.

A rotary surface cleaner puts two jets on a spinning bar under a shroud, so a Alexandria drive comes out one even color from the garage to the street.

Booking it in Alexandria

Send the Alexandria address and what needs cleaning. For most residential work we measure from property data and satellite imagery and come back with a number the same day. If the scope needs a closer look we come out, and it is free either way.

You do not need to be home. We need access to the areas being cleaned and an outside water connection, and we confirm both before the day.

Brick holds water, and water is the problem

Masonry is porous. It absorbs water and everything that arrives with it: algae in the shade, salts pushing back out as efflorescence, soil splash from the beds, and freeze damage where trapped water expands. High pressure drives more water in and can cut a mortar joint outright.

So brick and limestone on a Alexandria property get low pressure and the right solution, and where it is worth doing, a penetrating sealer afterwards.

Booked with something else

The crew is already at the property with water and access, so adding a second service costs a fraction of booking it as its own visit. In Alexandria the pairings that come up most are house washing, concrete & pavers.
