About Us.
Janville Home Improvements is a family-owned roofing and exterior contractor in Lansdale, PA. We started in 2003 and still run the same way.
A roof, siding, or window job is a major investment. We use quality materials, explain the scope before we start, and will not put our name on a project that is not installed to the standard customers expect. We serve homeowners and commercial properties across Landsdale and Montgomery County.
What You Can Count On.
Locally Owned
Estimates, scheduling, and job-site questions go to people who own the outcome. You are not handed off or meeting with a new manager you've never meet.
Licensed and Insured
We carry the insurance homeowners should expect on a roofing or siding project. Ask for current proof when you book the estimate.
Workmanship That Holds Up
We do not cut corners or overbook the calendar. Crews clean the site, install with care, and the completed work is backed by a workmanship warranty.

Trained professionals
For more than twenty years, Janville Home Improvements has built roofs, siding, windows, and gutters across Lansdale and the rest of Montgomery County. That history shows up in the work: square lines, tight flashing, careful tear-off, and a job site that is cleaned before the crew leaves. We treat each house as a custom project, not a production quota. Measurements are checked, materials are chosen for Pennsylvania weather, and details at chimneys, valleys, windows, and corners get the same attention as the parts you see from the street. Homeowners stay informed from estimate through final walkthrough because the people who sold the job are still the people responsible for how it looks when it is done.
FAQ
-
My roof leaks. Do I need to have it replaced completely?
Not always. A leak can come from flashing, a vent, a valley, or one worn section. We inspect first and recommend a repair when that will last. If the roof is at the end of its life or the decking is damaged, replacement is the better value.
-
How long can I expect my roof system to last?
A properly installed asphalt shingle roof often lasts 20 to 30 years in this climate, depending on material grade, ventilation, and storm history. Cedar and metal last longer when they are detailed correctly. Age, curling, granule loss, and repeated leaks tell us more than the calendar.
-
Are your services covered by my home insurance?
Storm damage and sudden leaks are often part of a homeowners policy. Coverage depends on your carrier and the cause of the damage. We can document what we find so you can file a claim. Routine age and wear are usually not covered.
-
When is the best time to do roofing repairs?
Not necessarily. It's possible that a section of your roof is loose, or that damage occurred in one place only. We'll conduct a thorough investigation before suggesting repair options.
-
Do you serve areas outside Lansdale?
Yes. We work throughout Montgomery County and nearby towns, including North Wales, Hatfield, Harleysville, Kulpsville, Montgomeryville, Colmar, Hatboro, Ambler, and Blue Bell. If you are close to Lansdale, call (215) 368-5200 and we will tell you if we can take the job.
-
Do you give free estimates?
Yes. We come to the property, look at the roof, siding, windows, or gutters, and give you a clear written estimate before any work starts.
-
Can you repair siding and windows, or only roofs?
We install and replace siding, windows, doors, and gutters as well as roofs. Many homeowners combine those trades in one project so the exterior is finished cleanly.
-
How long does a typical roof replacement take?
Most residential replacements take a few days, depending on roof size, weather, and whether decking needs repair. We confirm the schedule before the crew arrives and clean the site each day.
-
What roofing materials do you install?
Asphalt shingles are the most common. We also install cedar and metal systems when the house and budget call for them. We will walk you through the tradeoffs before you choose.
