Roofing in Dresher, PA

Dresher roofs wear out slowly, so the hard part is timing

Most of Dresher was built out in the '60s, '70s and '80s: split-levels, center-hall colonials and some ranchers on quiet side streets off Limekiln Pike and Twining Road. A lot of the people who live in them have been there for decades. The roofs are usually on their second set of shingles, and they rarely fail all at once. They fade.

That makes the real question here less "what broke" and more "how long have I got". A roof that looks fine from the driveway can have years left, or it can be one hard winter away from leaking. The only way to tell is to get up on it and look at the shingles, the flashing and the attic. That is what our free inspection is for, and we will tell you plainly if the answer is "leave it alone for now".

Knowing ahead means you can budget, pick a season, and replace the roof on your schedule instead of after a ceiling stain forces the issue.

Where split-levels and colonials leak

Where the low roof meets the tall wall

A split-level has a lower roof that runs into the side of the two-story section. That joint is sealed with step flashing: small pieces of metal woven in with each course of shingles and tucked behind the siding. When it was done right, it lasts. When someone ran a bead of caulk along it instead, water gets behind the siding and shows up as a stain on the lower-level ceiling or a soft spot in the wall. It is one of the most common leaks we trace in Dresher.

Attics that cook the shingles

Houses from this era often have small soffit vents, and a blown-in insulation job years later can bury what little venting there was. The attic gets hot in summer and damp in winter. Shingles over a hot attic age early, usually on the sunny south and west slopes first. Fixing the airflow at the next re-roof helps the new shingles last.

Old patches with different shingles

If you can see a patch of shingles that is a different shade from the rest, that is an old repair. It is not a problem in itself, but if there are several, and the roof is past 20, it is a sign you're near the point where replacement is better money than another patch. Our rule of thumb: once a repair costs more than about 30% of a new roof, put the money toward the new roof.

A 15-minute roof check you can do from the ground

Pick a dry, sunny afternoon. Bring binoculars if you have them. You don't need a ladder for any of this.

1. Look at the gutters and the end of the downspouts. A handful of sand-like granules after a storm is normal. Little piles every time it rains mean the shingles are losing their coating.
2. Compare the south slope to the north slope. If the sunny side looks lighter, blotchy or has curled edges and the shady side still looks even, the sunny side is ahead in the aging curve. That is usually where replacement starts.
3. Check where roofs meet walls and chimneys. Look for dark streaks on the siding below the joint, or a thick smear of black roof cement. Both point to flashing that has been patched, not fixed.
4. Go in the attic after a hard rain. With a flashlight, look at the underside of the roof boards for dark spots, rusty nail tips or drip marks on the insulation.

Selling in the next few years?: A buyer's home inspector will look at the roof. Getting it checked before you list lets you fix a cracked vent boot or a flashing joint for a few hundred dollars now, instead of negotiating a bigger credit later.

• Roof Inspection: Free
• Roof Repair: $350 – $2,500
• Roof Replacement: $6,500 – $18,000
• General Roof Maintenance: $350 – $2,250

Questions we get asked

Do you work throughout Dresher?

Yes, all of the 19025 area, including the streets off Limekiln Pike, Twining Road, Dresher Road, Susquehanna Road and Highland Avenue. We're in Horsham, right next door, and we work across the rest of Upper Dublin Township too.

My roof is about 20 years old and not leaking. Should I have it inspected?

Yes, it's worth it, and ours is free. At 20 years a roof can look fine from the ground while the flashing or vent boots are close to failing. You'll get photos and a straight answer on whether it needs anything now or can wait.

Why does my split-level leak where the lower roof meets the wall?

Usually the step flashing at that joint has failed or was caulked instead of properly woven into the shingles and tucked behind the siding. Water gets behind the siding and shows up on the lower ceiling or wall. The fix is new flashing, which often means lifting some siding and shingles along that line.

How much does a new roof cost in Dresher?

Most roof replacements we do fall between $6,500 and $18,000. Simple ranchers sit lower; split-levels with several roof sections, two-story colonials, and roofs with rotted decking cost more. We give you a free written, line-item estimate after we've seen the roof.

Should I fix the roof before I sell my house?

Often, yes, if the fixes are small. Replacing a cracked vent boot or resealing a flashing joint costs a few hundred dollars and keeps it off the buyer's inspection report. If the whole roof is worn out, we'll tell you that too, and you can decide whether to replace it or price it in.

Can I finance a roof replacement?

Financing is available through Hearth, our financing partner. Hearth handles the application and terms directly with you.
