Tree-lined suburban street in Montgomery County, Pennsylvania with a newly replaced roof

Montgomery County

Roofing contractor in
Montgomery County.

Older inner suburbs, midcentury splits and ranches, and newer colonials further north. Heavy tree cover across most of it, which is its own kind of roof problem.

Trees are the difference here. Montgomery County has some of the heaviest mature canopy in the region, and shade is hard on a roof. North facing slopes under trees hold moisture, grow moss and algae, and shed granules years before the sunny side does. Half the roofs looked at here are failing on one plane and fine on the other.

The housing stock

Three eras on the same street

The older boroughs, Norristown, Ambler, Lansdale, have twins and Victorians with steep pitches and detail work, close to what is found in the Lehigh Valley boroughs.

The midcentury belt is ranches and split levels from the fifties through the seventies. Those roofs are low pitch with long uninterrupted runs, which sounds easy and is, right up until the ventilation gets looked at. Most were built with almost none, and that is what cooks a roof from underneath.

North and west, through Blue Bell, Skippack and Harleysville, the stock is newer and larger. Multiple gables, dormers and garage roofs at a different pitch than the house, so the square footage runs well past what people estimate from the driveway.

What shade does

What turns up under tree cover

Moss and algae
Black streaking is algae and mostly cosmetic. Moss holds water against the shingle and is not.
Packed valleys
Leaf debris dams up a valley, water backs under the shingle, and the leak shows up nowhere near the valley.
Limb strikes
Small impacts that bruise the mat without breaking through. Invisible from the ground, obvious up close.
Clogged gutters
Constant load under heavy canopy. Overflow rots fascia and drip edge before it touches the roof.
Poor ventilation
Common on the midcentury stock. Shortens the life of whatever goes on next.
Uneven aging
The shaded plane fails first. A repair on that side buys less time than the same repair elsewhere.

Montgomery County questions

What people here ask

One side of my roof looks terrible and the other looks fine. Is that normal?

Under heavy tree cover, yes, and it is the single most common thing found in this county.

The question is whether the good side has enough life left to justify doing only half. Sometimes it does. More often the seams between old and new become the next problem, and that gets explained with photos rather than asserted.

Can the moss be cleaned off instead of replacing the roof?

Sometimes, if the shingle underneath still has granules and flexibility left.

Pressure washing a roof destroys it, so anyone offering that should be turned away. If cleaning is a reasonable option here, you will be told that rather than sold a replacement you do not need.

My roof is a low pitch ranch. Are shingles right for it?

Down to a point, yes, and below that point no.

There is a minimum pitch below which shingles cannot shed properly and a membrane is the correct material. That gets measured at the inspection instead of guessed.

Do you work this far south?

Yes. Montgomery, Bucks, Delaware and Chester counties are all in the regular working area.

There is no trip charge, and the inspection is free the same as it is at home.
